Android phone won't turn on - what to do? Android phone won't turn on. What to do? Doesn't work on Android

Since there are many different types of devices in the world, there are cases where Android apps don't work is getting bigger. There can be many reasons for this, from banal bugs on the part of the developer to failures in the device system.

Why don't apps work on Android?

Before moving on to possible ways to restore program functionality, you need to find out the cause of the failure. It does not always lie on the surface and is easily diagnosed, but it is worth trying to determine what precedes the failure, then the method of elimination will be more obvious.

Difference between smartphones and tablets. In some cases, the developer did not have time or ignored tablet support, and the program only works on phones. There are downsides to the issue, but they are quite rare. Alas, nothing can be done here until support for tablets/phones appears; nothing depends on you. You only need to find out on the application page about the platforms and devices on which it works;
It is likely that the game should work on tablets or smartphones, but it is not optimized for all device models. There are a lot of manufacturers, in addition to world names like Samsung, Lenovo, Sony, there are also Chinese brands. You should familiarize yourself with the models on which the application is supported or check with support; your smartphone is probably not one of these lucky ones;
You may have downloaded the wrong version of the application. In some cases, another version of the product is released that works directly for individual devices. Here it is best to download the game from the Play Market, where the required file will be selected for you;

You have an old version of Android. When everything works for other people with the same device, but not for you, then the likely reason is the lack of operating system updates. Option 2: simply update the system or report the problem to the developers;
Errors in the application. Obviously, even programmers are people who can make mistakes (given how much there is to take into account, this is quite likely). You just have to report an error and wait for a response.

In general, the user does not have many ways to restore the functionality of a problematic application, but some working options still exist.

What can you do if the application does not work?

When applications on Android do not start, you can use several tricks that can influence the program; there is no 100% guarantee that everything will work, but it’s worth a try. Let's look at the simplest options:

Minimize, restart the application. When using a certain program, it may cause problems. In case you minimize the application and then resume it again, it is re-processed and there is a high probability of restoration. So, while in the program, press “Home”, and then through the list of minimized applications (usually the left button) return it. If this does not help, close the utility completely and run the program again;
Clearing the cache. Quite often, when caching, certain errors occur or the memory allocated for this task runs out. To clear the section: click on “Settings”, then in the “Applications” category open “All”. Tap on the required program and in the “About the application” section click on “Clear cache”;

Clear data. The execution procedure is similar to the previous method, so on the same “About the application” page you need to click on “Erase data”. Be prepared, when you press the button, all your settings in the application will be erased, essentially returning it to its original state. Most often this method helps;

Reinstalling the program. As a last resort, you can uninstall the application and then reinstall it. This method is as old as life, but it still works. If the reason is not a problem with the system, then the option should resolve the error;

No updates. This also includes a new update. In some cases, not updating leads to certain bugs that have been fixed in future versions. Sometimes the situation is the opposite, the utility updated itself, but the update is crude and the developer did not take something into account, so the functionality has become partial or is completely absent;

Blocking by antivirus. Most antiviruses are especially suspicious of applications that are not signed and were not downloaded from the Play Market (sometimes they are also at risk). So blocking a program after it has been launched is a very likely consequence of the system’s protective function. You just need to add the utility to the antivirus exception or remove it.

Obviously, replacing the operating system, flashing the firmware, or updating the OS can also help you. In most cases, this procedure is not justified, since there are alternative programs or they are not so necessary. In case of urgent need, you can install a new version of the system.

Thanks to such simple methods, it is possible to restore the functionality of applications. In other cases, you will only have to rely on the developer, who will take into account previous errors and improve the operation of the application.

Nowadays, many people use mobile phones with Android OS. But what to do if your phone stops turning on?

There can be many reasons why Android does not respond to switching on, but to fix it, just follow these steps:

1. If your Android stops turning on, try resetting all settings to factory settings. We do this as follows: when you turn on the phone, hold down the power button and the volume button. A menu may open in which you need to select the “Restore factory settings” option. Just keep in mind that such a procedure will delete all your data, but it may also cure your phone.

Solution 8: Change the wireless range on your device

If you don't see the Advanced tab, you are not logged in as an administrator. Select Change Settings, enter your administrator password, and select Yes. If it still can't connect, try the solution. Try uninstalling and reinstalling the driver.

Solution 10

Are you having trouble playing video or audio?

If you have any of these video or audio playback problems, you can try some of these solutions. Nothing is displayed on the second screen. If you can connect your device to the adapter but don't see anything on the second screen, try the steps in the previous solutions. If this doesn't solve the problem, try the following solutions.

If Android starts loading and freezes, then a reset can be done using the code #3d5*361d4fb8#.

2. It is also possible that your Android firmware is damaged. To fix this you need to reflash your phone. If you do not know how to do this, it would be best to turn to a professional.

3. If none of the methods help, then the reason that the android does not start may be viruses that have deleted system files. In this case, it is better to take it to a service center.

You can't play video apps when connected to a wireless display adapter

Move the device closer to the adapter. . Close and restart or update the application. Solution 2: Disable your wireless network adapter

Video playback on device but frozen on second screen

If the video plays correctly on the device but is frozen on the second screen, unplug the adapter from the device and display and plug it back in.

Video appears on the connected screen, but audio comes from your device

If the quality of your video stream is poor, here are some ways to help improve it. The adapter works best if it is within 7 meters of the device. The source itself may be of low quality, which will affect the quality of the video transmission. Upload quality video. . If your device can hear audio when you stream video on a connected screen, you can manually set the audio source.

What to do if nothing helps?

You need to do some work on your system. We suggest you do this in two stages.

1. Update drivers with Driver Booster 3. This is really cool software that often helps! Updating old drivers to new ones is a very important point. You might think that Windows itself lets you know when new updates are available.

You can't change the resolution on your device

After disconnecting the device from the adapter, the device will return to the default resolution.

Whether the screen is not scaled or some parts of the screen are missing

If part of your device's screen is not visible on the second screen, the screen may not scale.

Adjust the resolution on your device

If the resolution on your device was set to a lower resolution than the default, you can increase the resolution so that it properly fits the second screen.

The app shows "Not Connected"

If the app shows a "Not Connected" message.

Yes, sometimes it shows alerts, but mostly only for Windows updates or sometimes also for the video card. But besides this, there are many more drivers that need to be updated regularly.

2. PC repair with Reimage Repair. Run this program to analyze your system for errors (and there will be 100% of them). You will then be asked to cure them, either individually or all at once.

The app always displays "Waiting for connection"

If the app always shows "Waiting to connect", first make sure your device is connected to the adapter, then unplug the adapter and plug it back in. Step 2: Select Connect. The adapter will not work if you are using a proxy server to access the Internet.

Please note that actual compatibility may be affected by the accessories included with your phone. You have to think about possible form issues, such as the placement of the side buttons. Turn on your device and attach it to your mobile device. When using portrait mode, the subject can move freely out of the frame without giving the gimbal time to adjust its orientation. The tracking speed cannot be set.

Every year electronic gadgets become more and more complex. The Android operating system, on the basis of which the vast majority of smartphones are created, is gradually acquiring more functionality. Sometimes this doesn't lead to anything good. Some devices regularly produce certain errors, freeze, and sometimes they cannot be turned on at all. The last case is the rarest. Most often, this is caused by unsuccessful flashing - which is why manufacturers recommend not to deal with this matter using standard firmware.

For this reason, we have redesigned the 5mm port as a dedicated port for downloading and updating firmware. You can use the trigger for multiple controls on both the gimbal and camera - hold it to lock the gimbal's direction or double-click to refocus. Unlike other osmo cameras, triple clicking does not rotate the phone.

Instead, change the camera your phone uses between the front and back cameras. You can control the digital zoom by pressing the shutter release and moving the joystick up or down. Please note that image quality will deteriorate when digitally scaling.

Android contains millions of lines of code. Even Google itself says that there are errors hidden somewhere in the depths of this code. They are eliminated with each update, but new ones appear at the same time. In most cases, these errors do not in any way affect the performance of the device. But sometimes some third-party application accesses the ill-fated piece of code, causing the smartphone to freeze. In such cases, a reboot usually helps. But there are also situations when after this the device does not want to turn on.

Therefore, the stabilizer is not removed. You can set the options manually from the Camera Settings menu. Go to Settings, select the live streaming platform and select the custom option and follow the on-screen instructions. The main difference is the speed of the gimbal, which follows your movements. In Sports mode, the gimbal closely monitors your movements, so it is appropriate to record targets moving at high speed. In Walk mode, the stabilizer reduces hand shake, allowing you to record stable shots on the move.

Don't assume that Google employs incompetent programmers. There are no fatal errors as such in a bare-bones operating system. But the creators of branded shells may well allow them. But in this case we are talking about some small manufacturers who do not thoroughly check the created software. This is why problems most often occur on devices from Cube and other little-known companies.

Yes, you can choose between slow, medium or high speed in the app. You can activate tripod mode when you record time-resolution videos at a fixed angle. However, when you are recording a hyperliz video, the tripod mode should be disabled.

To ensure optimal image quality, manual metering, focus, and zoom adjustments are disabled when recording time-lapse movies. The movement of your hands in this mode does not affect the recording direction of your phone's camera.

But more often than not, a smartphone turns into a “brick” after the user’s actions. In particular, such cases that occurred after updating the phone's firmware are widely known. More precisely, after trying to install custom firmware based on an inappropriate version of the operating system. This can become the most serious problem, which can often be “cured” only in an official service center with serious equipment.

Yes, you can use it in both cases. It takes 3 hours to fully charge, life expectancy is 3 to 5 hours. However, using an external target may affect the balance of the stabilizer. The use of long, heavy lenses is not recommended.

Thank you for your patience and understanding. Or maybe it has some sort of false contact where we have to push something out of it or put it in a certain position to charge it. There are many things on your mind: will it be a cable? Do I need to change my charger? Is the connector damaged? The truth is that in most cases, you don't even need to look for a spare since your phone may have a buildup of debris in the socket.

Other user actions that lead to the inability to turn on the device are associated with damage. For example, a person dropped a smartphone into water and immediately took it out. It may seem that this will not lead to anything terrible. But corrosion is a terrible thing. It gradually covers the metal elements. If it gets to the RAM, processor or some other components, then you can forget about turning on the device. In this case, there is a possibility that even the service center will not help. That’s why you need to take the device to a specialist immediately after it (the gadget, not the service center employee) has been in the water.

How to clean the connector on your smartphone

Over time, this prevents the cable from connecting properly and therefore your phone stops charging. If you are suffering from this problem, all you need is a dab, scissors and follow these simple steps. With scissors or precisely cut the tampon in half, but diagonally. This will create a plastic tip that will help remove debris.

Insert the plastic part into the connector. If you don't go in, you can smooth it out a bit. Never insert a pin, clip or any other metal object as you may permanently damage your phone. Remove any debris from the edges. The shape of the tip makes the job easy.

Trying to save a smartphone after being submerged in water

Now there are waterproof smartphones that are not afraid of even the most severe tests. But most of us own a device whose body allows water to pass through perfectly. If your Android smartphone or tablet falls into a river or a full bathtub, it will definitely not turn on after you take it out. If you are not able to immediately run to the service center, then do the following:

You can repeat the step in the hearing aid as sooner or later you will experience the same problem. If you've removed all the junk and your phone still won't charge, it's time to switch cables or switch charger. The last option is to take it to a service center for review.

It's very likely that you pair your cell phone before going to bed because you think it's better to wake up with a fully charged device. The fact is that many people don't expect to have their cell phones for more than two years. According to experts, most of these users will not discover damage to your cell phone battery because it happens before and wants a new device.

Step 1. Try to remove the battery. If you have a non-removable lid, then there is a high probability that nothing can be done without the use of special tools.

Step 2. Place the device in a plate with rice. Before this, you can blow off the gadget with a household hairdryer at a low power level.

Step 3. Wait a while. Rice perfectly absorbs moisture, as a result of which the smartphone itself becomes dry.

If this sounds familiar, feel free to charge it every night and as often as you prefer during the day. However, frequent use damages the lithium-ion batteries in our cell phones. Smartphones are inherently smart, Campos said. “They know when to stop loading.”

So in theory, any damage caused by charging your camera overnight should be negligible. However, charging cell phones is bad for your cell phone battery. Most phones use technology to allow their batteries to accept current faster.

Step 4. Take out the device and clean it of rice.

Step 5. Buy a new battery and insert it into your smartphone. Theoretically, you can try to turn on the device with an old battery, but this is risky - getting the battery into water could damage it.

After this procedure, many phones came back to life. But if your device has been in the water long enough, this may not help it.

This allows electricity to be transferred to the battery at certain modulations, increasing the speed at which lithium ions move from side to side; As a result, the battery charges faster. However, this process also causes lithium-ion batteries to corrode faster than normal.

When you charge quickly, you limit your battery life,” Zane said. Those who want to preserve their batteries should make sure their cell phones don't overheat, Campos said, because high temperatures overwork lithium-ion batteries, causing them to deteriorate faster.

Software errors

As we said above, the smartphone does not turn on not only after physical impact, but also after intervention in its firmware. If an attempt to install a different version of the operating system is unsuccessful, the device may refuse to load anything. But it is possible that this problem can be solved without the involvement of specialists with their special equipment. Try exiting to Recovery Mode. Different devices use their own methods for this. We wrote more about them in the article about. If you are in the Recovery menu, then do a hard reset. It is possible that this will help the computer identify the device so that you can install the previous firmware.

Zane and Campos mentioned that due to the constant demand for new cell phones, the normal procedure of charging them overnight will not be a big problem for many people. You may have encountered this problem several times, and you probably rushed to buy a charger when the solution was at your fingertips with a little effort and a little more knowledge.

Your phone may not charge when it's plugged in, your charge is very slow, or your device boots up too quickly. These smartphone and tablet problems are quite common, and the problem may have more than one explanation. If you notice that none of the cables are making good contact, this could be your problem. This must be done very carefully and very gently. Then reinsert the battery and connect the device. Nine out of ten times you just have to do it.

How to flash Android if it won't turn on?

If the device reacts at least somehow after you hold down the power key, then there is a chance of saving it. If there is no reaction, then try first connecting your smartphone to the computer, and then holding down one “Power” button or it together with the volume down key. If the PC gave a signal or even immediately identified the connected device, then you have every chance to flash your smartphone.

Clean the port and take precautions

Likewise, if the cable is not the problem, check the plug adapter on the wall, it may be the cause. Also test the same charger and cable combination with another device and see if it works fine. Sometimes the reason why a device won't boot properly is simply something stuck in the port, some kind of dust or dirt that is blocking the connection.

Of course, make sure you don't charge your phone near water or in excessively hot or humid areas. Also, you should not overload the device, an overnight charge is not needed, the battery only takes 2-3 hours to complete the job, and leaving it worse can cause terrible battery explosions or simply damage it in terms of capabilities.

There is no point in talking in detail about the methods for flashing a seemingly dead device. It all depends on the manufacturer, brand of smartphone and some other parameters. The only thing that should be noted is the fact that you will need a special flasher - a special utility from the manufacturer or third-party developers. Also, do not forget to get a high-quality USB cable that does not suffer from sudden loss of contact.

Summarizing

Sometimes the smartphone refuses to turn on after resetting the settings. In other cases, getting into water causes this problem. It also happens that even experienced specialists do not understand why the Android phone does not turn on. In short, the reasons for this are very different. We hope that our article helped solve your problem. If not, then you will have to either experiment with the device, resorting to the most fantastic means of resurrection, or contact a service center.

Everyone should know what to do if Android won't start. All the methods proposed below do not require additional technical knowledge and cannot harm the operating system or the device itself.

The Android operating system is not only the most popular in the world, but also very simple, convenient and reliable. Nevertheless, any modern device sooner or later fails or begins to work not quite correctly. Such an unfortunate incident is upsetting and can seriously damage your nerves. There are times when the problem is serious and only a specialist can help. But before you go to the service center, you should try a few simple tricks that can completely revive your smartphone.

Battery or charger

This may sound trivial, but more than half of the problems with turning on Android are related to the battery or charger. This is not about the fact that you simply forgot to charge your phone, but about more global reasons.

With prolonged and active use of a smartphone, its battery gradually wears out. There comes a time when it is discharged to such an extent that an ordinary network adapter can no longer help it.

If the phone model is old and collapsible, remove the battery and use the “frog” device. This is a charger that provides a more powerful charge and can save your phone for a while.

Photo: Frog for charging batteries

Owners of one-piece and non-separable models should not experiment at home. If you suspect that the battery may have failed, contact a service center to have it replaced.

The charging AC adapter may also be causing the problem. New chargers may not be original or compatible with this smartphone. This means that the battery does not receive energy during charging, and the android simply cannot start. In old chargers, contacts come off, wires break, etc. Therefore, it makes sense to try charging the phone from a different adapter.

Hardware problems (phone freezes)

It may happen that the phone is not turned off at all, but is “stuck” with the screen turned off. It’s worth figuring out what to do if Android doesn’t start due to freezing.

All procedures will be aimed at maximum activation and restart of the device.

If the phone has a removable cover, remove the battery for a couple of minutes, then replace it and turn on the device. Such a simple manipulation often gives good results and returns the smartphone to normal operation.

With more modern models the situation is a little different, but there is nothing complicated here either.

If, after a standard single press of the power off or lock button, the phone does not turn on, hold down this button for 10-15 seconds. After this, the screen may light up and the phone will continue to work.

The second way to reboot is the so-called “forced reboot”. To do this, you need to find the reset button and carefully press it with a needle, paper clip or toothpick. In all models it is located in different places, but it looks almost the same. If you can’t find the reset button, open the instructions for your phone.

There is another simple method that can “stir up” your phone. Connect it to your computer via USB. By detecting a new connected device or power source, the smartphone can wake up from its sleep mode.

Software problems

If none of the above methods help, the last chance to turn on the phone yourself will be a complete reset (in technical circles it is called).

There are also several methods and options here.

First, let's consider a situation where the phone still turns on, but does not work correctly and the android constantly freezes.

When you return to factory settings, absolutely all information will be deleted and the phone will become just like new. Therefore, if possible, be sure to back up all data. New models in their menu already have such functions as “data backup”, “backups”, and then full data recovery. Information can be copied to any existing account, Google Drive or to the cloud.

Photo: Phone backup

It is also possible to copy all data to a PC or laptop using a USB cable or, for example, a program Share it (Download). It is worth remembering that contacts from the phone book will be saved in one of the folders as a .vcf file.

To reset the settings, go to “Settings”, select “Privacy” (if Android version is 2.2 or lower), and then “Reset settings”. In the latest versions, go to “Settings”, select “Backup and reset” or “Backup and reset”, then click on “Reset”, “Reset settings”, “Reset Tablet PC” or “Master reset”.

When the phone is turned off and it is not possible to turn it on, you must simultaneously press the volume up button and the power button (on some models the volume button, the Home button and the power button). The Recovery technical menu should appear on the screen. You need to select the line wipe data/factory reset (down-up control is carried out using the volume key). Then click on Yes, delete all user data.

Do not forget that for a full rollback to factory settings, you need to clear the entire cache and SD card. To do this, you can go to “settings”, “memory”, “clear SD” or clear it immediately upon reset by clicking on wipe cache partition.

Important nuances of resetting settings

There are several very simple but important rules that must be followed. For example, during all operations with a smartphone, it must always be connected to charging. Then the phone will not turn off at the most important moment, ruining the entire settings process.

If you plan to reset the settings to factory settings in advance, you need to “overclock” the device’s battery. To do this, first discharge it until it turns off, and then fully charge it. This will ensure that the battery.sys file works correctly.

Since all phones are very different in interface and Android firmware, some users experience certain difficulties during the procedure. Don’t worry, be calm and read every menu name very carefully. If the smartphone model is very new or rare, it is better to study the instructions for it or go to the official website.

Problems after factory reset

Unfortunately, it is quite possible that the Android will not turn on after resetting the settings. You should again press the familiar volume up, power off and Home buttons and hold for 10 seconds. The Recovery mode menu will appear, select the “wipe” item, confirm your decision by pressing the Home button.

In a collapsible phone, remove the battery; under it there is a factory reset button. After pressing it, the settings will be reset again and the phone will turn on.

If the advice does not help, be sure to contact a service center to reflash the software.

conclusions

The tips listed are safe and quite effective. In most cases, with their help you can return the smartphone to normal and correct operation. You don’t need to rack your brain for a long time about what to do if your Android won’t start for one reason. In the event that home diagnostics do not give a positive result, you need to contact professionals. The cause of the failure may be serious, for example, completely faulty software, problems with the matrix, or other internal damage.

Dear readers! If you have any questions or comments on the topic of the article, please leave them below.

In four years, Android has transformed from a small but ambitious project into perhaps the most complex and feature-packed mobile OS of our time. Android supports a huge number of technologies and functions, many of which are hidden from the user or hidden in places you wouldn't even think to look at. This article is a collection of tips and tricks that can be applied to any Android device without the need to root.

01. DISABLE THE AUTOMATIC CREATION OF ICONS ON THE DESKTOP

I think I’m not the only one who is annoyed by the way the market behaves when installing an application. For some reason he thinks that for any more or less software or the next game I definitely need an icon on the desktop, and he successfully creates it. And I have to delete it. And then another one. And so every time.

Fortunately, this behavior is easy to disable - just open the Google Play settings (in the left panel) and uncheck the “Add icons” checkbox. There you can also disable the forced password request every 30 minutes when purchasing applications, as well as the hated auto-update of applications.

02. DISABLE GOOGLE SEARCH AND OTHER USELESS SOFTWARE

The standard firmware of Android smartphones includes a huge amount of useless software, ranging from a bunch of Google applications (do you know that Google requires manufacturing companies to include almost all the software it develops in the firmware of their devices?) and ending with all sorts of junk from the smartphone manufacturer . All of this (or at least most) can be disabled.

Go to “Settings → Applications → All”, tap on the desired software and click “Disable” (of course, you will be warned how “dangerous” this is). By the way, when you disable Google search, Google Now will disappear, as well as the search bar from the desktop (after a reboot), in its place there will be an empty area.

03. RESET TO SAFE MODE

Few people know, but Android, like many other operating systems, has a so-called Safe mode. This is a mode in which the operating system boots with third-party applications disabled. Malware that is not very skillfully written (one that is not registered in the system partition) then falls off, like any software that interferes with the normal operation of the system. Safe mode can be used to bypass screen blockers, applications that cause the smartphone to freeze, or, alternatively, to identify who is actually eating up the battery - the next firmware or software update.

The mode is turned on in a rather simple, but not at all obvious way: by holding down the power button and then holding your finger on the “Turn off power” item. After rebooting, the culprit of the problem can be removed through “Settings → Applications”.

04. GET RID OF INSTRUCTIVE NOTIFICATIONS

“The construction of the castle is finished!” - how did you get these notifications? Everyone who is not too lazy is trying to notify me about all possible and impossible events: “Vasya Dzhubga replied to you on Twitter,” “You have 100,500 new messages,” “You won surgery to enlarge your right leg.” You swipe away one notification, and three new ones appear in its place.

How to get rid of all this slag: hold your finger on the notification for a long time and uncheck the “Stop” button. This is the recipe for KitKat. In Lollipop, everything is a little different, but the essence is the same: hold down, then the i button, in the window that opens, put a checkmark on “Block”. There you can also force the notification to be a priority so that it is always at the very top.

05. DON'T FORGET ABOUT THE SERVICE MENU

Another not at all obvious function is the service menu. It can be opened by dialing *#*#4636#*#*. Basically, there is various technical information like IMEI number, signal strength, current location or network type. But there is also a very useful function for some situations to force the smartphone to switch to the desired type of network (2G, 3G, LTE).

In conditions of poor 3G/LTE signal levels, the device tends to reset to 2G in order to save battery power and ensure subscriber availability. This behavior can be disabled. Open the service menu and in the “Set up preferred network type” item, select WCDMA only or LTE only. In the same way, you can switch your smartphone to 2G - GSM only. It will help if you need to save battery power and the Internet is rarely used. By the way, you can also disable the radio module there altogether (until the next reboot, of course).

Smartphones based on Chinese MTK chips have their own and much more sophisticated service menu. His number is *#*#3646633#*#*. There is various system information and a huge number of tests, among which you can find several useful settings, such as adjusting the volume level during a call or, for example, changing GPS/AGPS settings. The menu itself is terribly illogical and contains so much varied information that I don’t even dare to describe it, but will simply send the reader to three letters - XDA.

06. USE A STANDARD BROWSER

I don't know why users don't like Android's built-in browser so much. In my opinion, he is wonderful. Lightweight, fast, powered by the Chromium engine, can synchronize with a Google account (that is, it immediately includes all bookmarks and passwords from Chrome), but most importantly, it has a very convenient and almost ingenious navigation method. This is the so-called radial menu, which can be activated in the settings (only in Android 4.0–4.4).

07. MANAGE CONTACTS FROM YOUR COMPUTER

Google has web services not only for remotely installing software, blocking and searching for a smartphone, but also for managing contacts. All people's contacts ever saved and synchronized when connecting a new smartphone can always be found on the page google.com/contacts. They can be viewed, edited, added and deleted. Moreover, oddly enough, it is essentially part of Gmail.

08. MONITOR YOUR PROCESSOR LOAD

Android has a built-in feature that displays the current CPU load and currently active processes on top of the screen. In theory, it is intended for application and firmware developers and is hidden from ordinary users, but no one is stopping us from activating it. But first you will have to reach the “For Developers” settings section, which by default does not exist at all.

Go to settings, then “About phone”, find the line “Build number” and tap on it seven times in a row. The message “You have become a developer!” should appear on the screen. This means that the “For Developers” item is now open, and we go to it. We rewind almost to the very bottom of the screen and in the “Monitoring” section we find the “Show CPU load” switch.

Turn it on and see a list in the upper right part of the screen. The first line is the so-called loadavg, which shows the number of processes that had to run or wait their turn to run in the last minute, five and ten minutes. To put it very roughly: if these values, divided by the number of processor cores, are above one, this means 100% processor load in the last minute, five or ten minutes, respectively. Below is a list of the most power-hungry processes (essentially, an analogue of the top command from Linux).

09. USE ADB TO BACKUP SOFTWARE ON YOUR COMPUTER

We have already written more than once about a wonderful tool called ADB, which can significantly simplify managing a device from a computer for a person who is familiar with the console (here we are mainly talking about Linux, of course). In addition to the ability to install software, transfer files to a smartphone, view logs and other useful things, ADB has recently made it possible to backup all smartphone settings and applications.

To use this functionality, install the universal ADB driver (goo.gl/AzZrjR), then download ADB itself (goo.gl/3P7klM), install the driver, then expand the archive with ADB, connect the smartphone to the computer with a USB cable, launch the command line and execute the command

A message will appear on the smartphone screen asking you to specify the encryption password for the backup - you can safely press “Next”. The application backup process will begin, which will affect both the APK packages themselves (the -apk flag in the command) and their settings. All applications from the memory card will also be included in the backup. You can restore a backup using the following command:

$ adb restore backup . ab

10. DISABLE BACKGROUND DATA TRANSFER IN APPLICATIONS

Working in the background, applications can actively use the Internet for a variety of purposes, from updating their content to leaking information about your location. In addition, such activity in any case leads to increased battery consumption.

Android has the ability to selectively restrict applications from transferring data in the background, but it is located in a place where most users would hardly ever look. To prevent any application from using the Internet in the background, you need to go to settings, then “Data transfer”, scroll down the screen to the list of applications actively using the network (for some it will be a surprise that it is there at all) and tap on the desired software. At the bottom there will be an option to “Limit background activity”. It is worth keeping in mind that the option will disable data transfer only over the mobile network, so data will continue to flow over Wi-Fi.

11. USE THE SEARCH BAR

Often, owners of Android smartphones neglect the search bar at the top of the main screen. This is really logical, given the ability to search by typing a request into the address bar of any mobile browser.

Meanwhile, the desktop search bar does much more than just redirect your request to google.com. It allows you to search contacts, applications, calendar events, bookmarks and web browser history automatically. For normal smartphone use, it may not be as useful, but when connecting an external keyboard, it is an indispensable tool. Just click and enter the name of the application, contact or anything else, and it immediately appears on the screen.

12. USE SMART LOCK

Smart Lock is one of those features that you don’t think about, but once you try it, you can’t live without it. This is one of the most notable new additions to Android Lollipop and one of the most useful features added to Android recently. The idea of Smart Lock is extremely simple - it disables the PIN code or other lock screen protection if there is a specific Bluetooth device or map location nearby.

By default, Smart Lock is “sort of” disabled. That is, it does not light up anywhere, but after pairing with a new Bluetooth device (of any type), it will definitely offer to add it to its white list. After this you will forget about her again. But only until you enable lock screen protection in the “Security” section of the settings. Now it will work as it should.

The Smart Lock settings themselves are in the same section, and, in addition to adding new Bluetooth devices, you can specify “safe places” there, along with a list of options based on Google Now “observations.” By the way, if you disable it, as described in the first tip, then this functionality will also be lost.

13. SAVE ENERGY RIGHT

Another notable innovation from Lollipop is its power saving mode. It migrated to standard Android from the firmware of smartphone manufacturers, who previously sold it independently. Now the function is available in pure Android - you use your smartphone to the fullest, and when the battery charge reaches 15%, the system prompts you to turn on the power saving mode, which turns off background data transfer, reduces the brightness to a minimum, turns off some sensors and reduces the screen rendering FPS to a couple of dozen frames per hour. give me a sec. For clarity, the status bar and on-screen buttons at the bottom of the screen turn red - so you don’t forget.

To save battery life on a smartphone with an AMOLED screen, you can set black wallpapers and use apps with black backgrounds.

The energy saving mode is customizable. Go to “Settings → Battery → menu → Power saving mode.” Here you can specify the condition for automatically turning on the mode (though the choice is meager: 5%, 15% or never) and, most importantly, turn on the mode right now. Very convenient if you have a long trip ahead without the possibility of recharging.

14. MONITOR TRAFFIC

Most likely, smartphone manufacturers, as usual, will shovel the standard Android 5.0 interface and change everything (hello Samsung - the biggest fan of breaking interfaces), but in the standard Lollipop curtain, or rather, in the “second curtain” with
There is one highlight to the quick settings options. The data transfer button in the center does not switch data transfer at all, but expands into an interface that allows you not only to view the current traffic consumption, but also to disable data transfer using the switch on top.

15. SHARE NOT YOUR PHONE, BUT AN APPLICATION

Especially for those who like to give their phone to other people, Lollipop has a Screen pinning feature that allows you to lock your smartphone on one application without the ability to close it or switch to another. Like many other useful features, it is completely invisible and hidden quite deep in the settings. To activate, go to “Settings → Security”, scroll almost to the very end and turn on the “Block in application” option.

Now, if you click the View running applications (Browse) button, an pushbutton will appear at the bottom of the current application's thumbnail. Once you tap the icon, the screen will be locked on the selected app and you will need to hold the Back and Overview buttons simultaneously to go back. In this case, you will have to enter a PIN code if it is set for the lock screen.

XX. USE ACITIVITY LAUNCHER

Any graphical Android application includes one or more so-called “activities”. Each of them is an application window (screen), for example the main screen or the settings screen, maybe even a file selection window. By default, you can open directly (from the desktop) only those activities that the application developer marks as main; the rest are accessible only through the application itself and only if the developer himself allows this.

However, having the right tool at hand, you can reach any other activity of any application and even create a shortcut for it on the desktop. Activity Launcher does just that. Just install the application, select “All actions” in the menu at the top and find the software you need. All of her activities will appear on the screen, and any of them can be opened with a simple tap or placed on the desktop by holding your finger for a long time.

An example of useful “internal” activities is the Chrome bookmarks window (Chrome →Bookmark), access to the hidden AppOps mechanism in Android< 4.4.2 (Настройки → AppOps), запуск поиска в TuneIn Radio (tunein.ui.activities.TuneInSearchActivity). Очень много активностей имеет в себе ES Проводник, включая редактор, музыкальный плеер, просмотрщик изображений и многое другое. Любую из них можно запустить напрямую с рабочего стола. Таким же образом можно открыть любой раздел настроек и получить доступ к некоторым функциям ОС, достучаться до которых проблематично. Это абсолютно легальная функцио нальность, и она не требует root.

Android has a large set of hotkeys for connected keyboards. You can use Arrow, Tab, and Enter to navigate the desktop and various menus. In addition, the following key combinations are available:

Esc - “Back” button;
Win + Esc - Home button;
Ctrl + Esc - “Menu” button;
Alt + Tab - switch between applications;
Ctrl + Space - switch layout;
Ctrl + P - open settings;
Ctrl + M - manage installed applications;
Ctrl + W - change wallpaper;
Win + E - write a letter;
Win + P - music player;
Win + A - calculator;
Win + S - write SMS;
Win + L - calendar;
Win + C - contacts;
Win + B - browser;
Win + M - Google maps;
Win + Space - search;
To find out your MAC and IP address, go to “Settings → Wi-Fi → menu → Advanced
new functions.” MAC and IP will be at the very bottom.

Lollipop has a built-in Flappy Bird style game. Go to “Settings → About phone”,
Tap on the “Android Version” item several times, then hold your finger on the “Lollipop” that appears. Let's play.

Google Now supports a large number of Russian-language voice commands. All of them can be divided into two groups: voice search and the voice commands themselves. Voice search allows you to perform smart searches on Google, where the system displays a specific answer on the screen instead of a list of links, and voice commands allow you to perform certain actions, for example, send an SMS or set an alarm. The list of commands is shown in the Google Now Voice Commands image. Voice search includes more than a dozen different types of questions:
Weather. What will the weather be like tomorrow morning?
Addresses. Where is the nearest pharmacy?
Flight information. When does Aeroflot flight number 2336 depart?
Time. What time is it in London?
Events. When is sunset today?
Computing. What is the square root of 2209?
Translation. How do you say "cucumber" in Spanish?
Sport. When does Spartak play?
Finance. What is the S&P 500 index today?
Data. What is the height of the tallest building in the world?
Exchange Rates. Convert 2600 rupees to US dollars.
Images. Show photos of the Golden Gate Bridge.
Interestingly, Google Now understands a large number of much less obvious questions in English. As an example we can give:
Should I wear a jacket today?
How much tip for 420 rubles?
Where is my parcel?

This, of course, is not all that could be talked about, but it will not be possible to lengthen the article, and many of the other possibilities are already known. Don't forget about these tricks, and your smartphone will become
a little more convenient.

You can download and install official firmware “over the air” if you go to the appropriate settings menu or through a proprietary utility on your computer. But what to do if your Android has not been updated for a long time, or if it gives an error when updating? Let's look at the possible causes of this problem, as well as ways to solve them.

The problem with updating the phone's operating system is quite common. It is inherent not only to owners of older models, but also to users of the most modern Android devices. In most cases, it is not possible to update the phone due to the lack of necessary firmware on the developer’s website. But there are also reasons related to the presence of system errors in the mobile phone’s software or even mechanical damage to its components. In any case, each of the possible reasons deserves separate consideration.

Unlike IOC, developers of the Android mobile OS are forced, in addition to the firmware itself, to also work on its compatibility with many devices. This leads to the need to create drivers and other software, without which the correct operation of the system is impossible. Also, Samsung, LV, NTS and many other companies use proprietary shells on top of the operating system itself. As a result of all this, in most cases, only new and current smartphone models receive updates. And older devices, including due to a lack of hardware resources: RAM and processor power, remain without software updates.

Problems with Google services

If an update has been released for your phone, but it is not displayed in the settings, then the problem may be with the Google Services Framework service. The reasons for service failures may be its incorrect updating, infection of the phone with malware, etc. In any case, in order to update Android to the latest version over the air, you cannot do without this service.

Installing unofficial software

Official updates for Android are available only for devices whose owners agree to the developer’s software use policy. If the installation of applications from unverified sources is enabled on your phone, an update error may occur. The same applies to downloading custom firmware and recovery, as well as devices on which administrator rights have been obtained. For such smartphones, you will not be able to install official OS updates, either over the air or using a proprietary utility on your computer.

Virus infection

Without antivirus software, the phone's operating system is susceptible to malicious files. Virus programs can be downloaded from the Internet, or by installing apk applications from unverified sources. Since the effects of malicious files can be very different, one of the possible options is to block the service responsible for updating the Android OS.

Incorrect installation of updates

When updating Android, you must wait until the files are completely downloaded and installed. In this case, the device spontaneously reboots a couple of times. Problems may arise if an error occurred during the installation of updates caused by one of the following factors:

The Internet stopped working on my mobile phone.
The battery has run out of charge.
The phone was forcibly turned on, etc.

This can not only cause the update installation service to not work, but also render the phone inoperable.

Hardware failure

The least likely, but also possible reason is a broken phone. If, after updating the OS, the mobile phone does not see the SIM card or simply does not start, it may have hardware problems. In most cases, this is the result of a manufacturing defect or occurs after the smartphone falls on a hard surface or gets moisture inside.

Solution

To solve problems with updating Android, you may need root access rights to the phone system. But in simpler cases, you can try to do without them. In any case, you must first perform a forced check for new OS versions in the main settings menu. Let's consider all the methods in more detail.

Forced verification through settings

The new OS version may not appear in the notification list until you go in and download it yourself. You can force a check for updates in a few clicks through the main settings menu; to do this, you need to find and select the “OS Version” item. In it you need to click on the “Check now” line and wait until the system connects to the developer’s server. Naturally, the Internet on the phone must be turned on, preferably a Wi-Fi connection.

Verification via USSD request

An alternative way to force verification is to dial a combination of numbers into the dialer. To do this you need:

Open the phone book and dial a number.
Dial request *#*#2432546#*#*.
Wait until the system performs a check.

In this case, you do not need to confirm your request by pressing the call button.

Clearing Google Services Framework data

Clearing the Google Services Framework data can help solve the problem with the update. To do this, go to the main settings menu and tap on the “Applications” item there. In it, use a side swipe to select “all applications” and find the Google Services Framework in the list provided. By clicking on the desired service, a management menu will open in which you need to clear the data by clicking on the corresponding button.

Using a PC on which proprietary utilities from the developer are installed

A reliable way to install the latest updates to your mobile phone operating system is to use proprietary utilities from the developer. In this case, you will also need to download the latest version of drivers for your mobile device on your PC. Let's consider the algorithm of necessary actions for Samsung smartphones and the proprietary Kies program:

Create a backup copy of your data, if necessary.
Download and install the Samsung Kies utility from the developer’s official website.
Connect your mobile phone to your computer via a USB cable.
The program will automatically recognize the device and display information about available firmware versions on the screen.
Confirm the request to install new firmware.
Read the supporting instructions and click on the “start” button.

Installing firmware via the proprietary Kies utility

When performing these steps, the firmware will begin downloading through a special utility, and the phone itself will go into Download mode. After this, the mobile phone will reboot with the already updated OS, and a notification about the successful completion of the process will appear in the Kies program.

Installing third-party, custom firmware

If none of the methods worked, and you are unable to install the official firmware on your mobile phone, then download a custom one. True, in this case you will need to root the device and say goodbye to the manufacturer’s warranty. If this is not critical, then we recommend paying attention to Cyanogen. This firmware is very popular and supports many functions that are not available in official versions of Android.

Installation of third-party firmware is possible both through the recovery menu and using special programs. If system failures or software problems occur, in this case it is easy to make a backup or reset to factory settings.
