Can't complete Touch ID setup on iPhone, what should I do? What to do if Touch ID doesn't work in the App Store? A simple way to solve this problem How to understand that touch id does not work.

A fingerprint scanner has ceased to be something special - today not only flagship models, but also many decent-level smartphones have it. The fingerprint scanner is used to unlock the device, protecting it from unauthorized access. It is also used as a security element for some applications. This is a very convenient and reliable solution, but, unfortunately, only until the moment the scanner stops responding properly to the owner’s finger.

Possible causes of malfunction

All the reasons for the failure of a fingerprint scanner to perceive the fingerprint of the smartphone owner and respond properly to it can be divided for 4 groups:

Damage to the button sensor cable (when you open the device yourself or after a strong impact);
Software failure;
The surface of the button is wet or heavily soiled;
Changes in the fingerprint pattern (physical damage to the skin, its hardening due to frostbite, exposure to chemicals, callus formation).

Ways to fix the situation

Option 1: If you are sure that the sensor cable is damaged, take your smartphone to a repair shop. In most cases, craftsmen manage to cope with the breakdown.

Option 2: Update your smartphone software. You may have missed an important update, which caused the scanner to malfunction. If, on the contrary, the scanner stops working after installing the update, return to the previous firmware version. You can perform a factory reset (don't forget to create a backup copy first so as not to lose all the information from your smartphone).

Option 3: Using a damp (not wet!) cotton swab soaked in alcohol, gently wipe the surface of the button. Dry it and check if the sensor is working. Touch the button only with clean and dry fingers.

Option 4: The method associated with replacing a fingerprint is very effective. The operation of the fingerprint scanner is not only normalized, but also accelerated. The procedure is as follows:

No matter how ridiculous this method looks, it works and works great - tested on Xiaomi smartphones.

Apple provides users of its technology with a large number of functions designed to ensure complete security and protect the device from unauthorized persons. One such add-on is Touch ID.

What is Touch ID

Touch ID is a password that can be set to unlock the device or access certain applications. Unlike previous passwords, which were a combination of numbers or a key character, Touch ID checks the fingerprints of the person trying to unlock the phone or tablet and compares them with the fingerprints stored in the device's memory. If they match, then the unlocking is successful, but if Touch ID suspects that they are trying to hack the device, it will go into lock mode. The user has three attempts to prove their identity using unique fingerprints.

The advantage of this technology is that it is the most reliable way to block access to your device or individual programs. If a phone or tablet is stolen, it will be very difficult for an attacker to remove it from the locked state.

Touch ID first appeared on the iPhone 5S and is present on all subsequent phone models. This technology is also available on iPad Air 2 and iPad mini 3.

How to enable, disable and configure Touch ID on iPhone

Before activating Touch ID, it is recommended to restart your device, close all applications and wash your hands, since the first time you turn it on you will need to add your fingerprints, and if they are unclear, you may have problems unlocking the device in the future.

Open the Settings application.
Go to the “Touch ID and Passcode” section.
Click the “Add fingerprint” button. Detailed instructions for adding a fingerprint will appear on the device screen. It will be necessary to apply your finger several times, raising and lowering it at the right moment. Hold the device the way you normally hold it. Don't place your finger straight or at a certain angle; place it on the Home button the way you most often place it during everyday use.
If you think that the fingerprint is inaccurate, then find it in the “Fingerprints” block and swipe it from right to left. A “Delete” button will appear, which you must click to erase the fingerprint.
You can click on the name of the resulting fingerprint to assign any other name.
Now we activate the “Unlock iPhone” function if you want the device to unlock only after touching it with your finger.
Activate the "iTunes Store, App Store" feature if you want your fingerprint to be required when entering the store.
If you want to disable Touch ID technology on your device, then deactivate the two features above.

What to do if a function stops working or crashes

Some users experience problems immediately after enabling Touch ID, while others experience problems after a few days or months. The problem may be the following: Touch ID does not work, has stopped working, does not work the first time, does not work correctly. To get rid of all the above problems, you need to do the following:

Reboot your device by pressing the Lock and Home buttons at the same time for 8-10 seconds.
Open the Settings app.
Go to the Touch ID and Passcode section.
Delete any existing prints. To do this, first click on the name or fingerprint number.
In the tab that opens, click the “Delete fingerprint” button. Repeat this operation with all prints.
Click the Add Fingerprint button. Follow all the instructions that appear on the device screen: remove and reapply your finger, rest the tip or middle of your finger, rotate, and others. Repeat this process with each finger.

If restoring fingerprints does not help fix problems with Touch ID, you need to take the device to a service center to get advice from a qualified specialist and possibly send the device for repair, since the problem is most likely in the hardware of the phone or tablet. If you hacked the firmware of your device using Jailbreak, then this may be the reason. Also, the reason may be in the IOS version; you need to install the latest firmware on your device for Touch ID to work correctly.

Of course, such protection was to the taste of users who immediately began to use all the benefits of “Apple products”. However, after some time, numerous complaints began to appear on the official Apple technical support website that the Touch ID setup could not be completed. Such a useful solution turned out to be completely ineffective? Or can the problem be solved? Let's take a closer look in the article.

Causes

There are many factors that can affect the performance of a smartphone. Some attribute the failure to complete Touch ID setup to the redesigned stock apps, new Siri features, changes to the CarPlay interface, and more. However, the reasons may be much more trivial than it seems at first glance.

Most often, problems with the scanner appear at subzero temperatures. In this case, the Touch ID setup cannot be carried out due to the fact that the touchscreen is simply frozen and cannot recognize the user. In addition, in cold weather it also changes on a person’s fingers. Of course, this cannot be seen with the naked eye, but for sensitive equipment this is a huge problem. Therefore, if you were unable to complete the Touch ID setup, return to a warm place and try to repeat the procedure again when the device and your hands are warm.

The second common reason is dirt and moisture. If you try to set up the scanner in the rain or in cloudy weather, when high humidity prevails outside, then most likely nothing will work. The same goes for dirty hands. Again, your fingers may look clean on the outside, but this will not be enough for the scanner.

Of course, there are more serious reasons why Touch ID setup couldn't be completed. Quite often the problem occurs due to incorrect settings or a short program crash. The reason may also lie in the hardware.

Correct setting

In order for Touch ID to work fully, you need to configure it. To do this correctly, you need to follow these steps:

Make sure the Home button is clean and free of moisture. Hands must be dry.
Go to your phone settings and select “Touch ID password”. Enter the code combination.
Click “Add fingerprint” and calmly touch the Home button without pressing it too hard.
Hold your finger still until the device begins to vibrate.
Repeat the procedure. The finger must be lifted several times and pressed against the button again. It is recommended to change its position slightly.
A new menu will appear on the screen where you will be asked to adjust the fingerprint capture. To do this, you need to take the phone in your hand in the most convenient way and place your fingertip on the Home button. This procedure is also repeated several times.

If you still can't complete the Touch ID setup, you can try using another finger. Or use another method.

Restoring Touch ID

To rollback previous changes and set new settings, you must complete the following steps:

Go to the main menu and select “Touch ID password” again.
Enter the access code and delete old biometric data.
Repeat the procedure for adding a “cast”.

If after this you still cannot complete the Touch ID setup on your iPhone, you can try restoring the system via a backup that was previously made in cloud storage or on your PC. To do this, you need to connect your device to your computer and go to iTunes. Next, you just need to click the “Restore” button and select the desired backup date. After recovery, you must re-enter your biometric data as described earlier.

If the problem is hardware

If there is a non-software failure and you cannot complete the Touch ID setup, then the reason may lie in the device itself. The Home button cable may have come loose. To solve this problem, you need to carefully disassemble the phone. Then you need to disconnect the cable from the button, check if there is any damage on it, and re-insert it. In some situations, this helps fix the error.

However, such experiments should not be carried out without proper experience. If the user is confident in his abilities, then before performing such operations it is necessary to save all data from the smartphone.

If Touch ID stops working in the App Store

Very often, users notice a problem with the scanner only when they go to the official Apple store. However, if the fingerprint is not removed in the App Store, this may also indicate a problem with the device.

In this case, you must perform the following steps:

Go to settings and go to “Touch ID password”.
Enter the code and find the “Usage” section.
Disable the App Store and iTunes Store in it.
Reboot the device.
Go to the settings again and repeat the procedure, only this time the stores must, on the contrary, be activated.

This usually helps get rid of bugs.

Technical support

If none of the above helped, do not despair. Experienced Apple support technicians can help you figure out why you can't complete Touch ID setup. To do this, you need to go to the company’s official website and create the appropriate ticket. Or you can search in the questions already asked. Most likely, there are a large number of discussion threads on the site with similar problems. If the consultants suggest doing everything that has already been stated, then all that remains is to go to the service center and try to diagnose the device. Before doing this, you should copy all the data from the phone again.

The first Apple smartphone with a Touch ID fingerprint scanner was the iPhone 5s, which entered the market back in 2013. Since then, the Apple corporation has managed to develop and begin to implement the second generation of the fingerprint module, which is characterized by increased recognition speed and increased reliability. However, problems may arise with any generation of Touch ID, so the editors website I decided to tell you about five ways to fix a poorly working fingerprint scanner in iPhone and iPad.

Activate Touch ID in iOS Settings

Before you start looking for the reason for the fingerprint scanner not working in the iPhone and iPad, you should make sure that it is enabled in the settings of the iOS operating system. To do this, you need to launch the “Settings” application, and then go to the “Touch ID and passcode” section and activate the toggle switches opposite all the parameters associated with this module. If they are already turned on, then they can be turned off and turned on again in order to eliminate the possibility of some kind of bug.

Clean the module from dirt and dust

Since Touch ID scans your finger, you should always keep it clean. Of course, you shouldn’t overdo it when cleaning it, but dirt and dust can cause poor performance of the entire module and lead to incorrect fingerprint recognition. You can clean Touch ID from dust and dirt using a special solution for cleaning electronics. It should be sprayed onto a microfiber cloth and thoroughly clean the entire module for a few minutes, and then test its operation.

Update your iOS operating system to the latest version

Despite the fact that the iPhone and iPad are among the most reliable mobile devices in the world, some failures and glitches may occur in the operation of the iOS operating system. As a result, the Touch ID module may not work entirely correctly on certain firmware versions. This problem is solved by updating the device to the latest version of iOS, which probably does not have software problems with Touch ID.

Finger position when scanning

In some cases, unlocking iPhone and iPad using Touch ID may not occur for the simple reason that the fingerprint scanner cannot scan. To help him do this, you should place your fingertips all over the fingerprint scanner. Additionally, Touch ID takes a while to scan, so don't remove your finger from the scanner too quickly.

Adding more fingerprints

All iPhones and iPads can add up to five fingerprints, which can be used to unlock the device. Apple does not impose any restrictions on this, so the same finger can be scanned several times, thereby increasing the chances of successfully unlocking the device with its help.

If all the described methods for solving Touch ID problems did not help, then you should think about visiting a service center. It often happens that the fingerprint modules in the iPhone and iPad fail and the only way to solve the problem is to visit the ASC. Please note that repair or replacement of Touch ID can only be done at authorized service centers that are able to “link” a new fingerprint scanner to the old hardware.

Until December 22 inclusive, everyone has the opportunity to use Xiaomi Mi Band 4, spending only 1 minute of their personal time on it.

Does the Touch ID fingerprint sensor on a fairly recent iPhone not always work when touched and you have to constantly enter the password? If you encounter a similar problem, then in this material we will tell you how to fix it.

Everyone knows that after purchasing a new iPhone, it is necessary to complete the activation procedure and initial setup of the device, which includes setting up the Touch ID fingerprint sensor built into the Home button. The user is asked to add a fingerprint with which the iPhone can be unlocked.

From our many years of observations of users setting up a new iPhone, we can say with confidence that adding a fingerprint to Touch ID during the initial setup of the device is often done very quickly and not always with an understanding of the process. Most users hold their iPhone differently than during normal use when setting up the biometric sensor. This is where the whole secret lies.

In addition, after setting up the iPhone for the first time, few people return to the Touch ID options (in iOS settings) to continue the process of improving the sensor's performance. As a result, users continue to use the single fingerprint that was recorded in Touch ID when they first set up the iPhone. But in the sensor parameters you can add as many as 5 prints. So…

Touch ID doesn't work well on iPhone: how to properly set up the fingerprint sensor on iPhone or iPad

1 . Open the Settings app on your iPhone or iPad and go to Touch ID & Passcode.

2 . Enter your passcode.

3 . Remove any added fingerprints. To do this, select each fingerprint and click Delete fingerprint.

4 . Click Add a fingerprint.

5 . Hold your iPhone or iPad the same way you would normally hold the device before unlocking it.

6 . Go through the process of adding all five fingerprints this way:

add your fingerprint twice Right thumb;
add your fingerprint twice Left thumb;
add your fingerprint once Index finger of the right hand(if you are right-handed) or left hand (if you are left-handed).

The point of this operation is to add more fingerprints to the most used unlock option. The scheme we have proposed can be changed if desired. For example, if you always unlock the device using one hand, then it would not be superfluous to add 3, 4 or even all 5 possible fingerprints to the Thumb.

Try it now. In the vast majority of cases, this will solve the problem of poor Touch ID performance.

If, after completing the procedure for adding fingerprints, the sensor still does not respond well, try rebooting the device. If the reboot does not help, then there are two options left - either you are the owner of hands with an abnormal fingerprint structure (we have met such users) or the problem is still in the Touch ID sensor itself.
