Samsung Galaxy S2 I9100: review, description, specifications and owner reviews. Samsung Galaxy S2 I9100 phone: characteristics, comparison with competitors and reviews Bluetooth is a standard for secure wireless data transfer between different devices

Nobody questions the success of the Galaxy S line anymore. This is the only line of smartphones that not only became famous and popular, but was able to largely surpass the famous iPhone, which was considered the standard for almost a decade. The success story of this series began with the first model released on the mass market, but it was the second version of the gadget that left a special mark in the memory of users. Samsung Galaxy S2 i9100, the characteristics of which were simply discouraging at the time of release. None of the competitors could even come close to it in terms of the power of the “filling”. The technologies that were involved in this device were not available to other manufacturers, so the Koreans, without wasting any time, used their trump card and decided to bring to the market all the best that they had, thereby seizing the championship banner from Sony and HTC. Since then, Samsung has become the trendsetter and the main engine of progress in the difficult conditions of the struggle for the smartphone market. In this article we will talk about one of the most prominent representatives of this industry - Samsung Galaxy S2. Is he really that good?

Case design and materials

Dimensions: 125x66x8.5 millimeters.

Weight: 116 grams.

The main design solutions were carried over to the Galaxy S2 from the first generation of smartphones. The same plastic as the main material, the same hump on the back panel, except that the phone has become a little wider compared to the previous model, which caused a lot of negativity on the Internet. An important difference was the thickness of the device. From a value of 11 millimeters, the thickness of the case has dropped to 8.5, which is impressive. The back cover has a corrugated surface, a kind of imitation of leather on plastic. Visually, this solution looks, to put it mildly, vulgar, but in practice it works perfectly. This surface does not allow the phone to slide, thanks to it there are almost no small scratches, and even less fingerprints. Only the hump in the lower part of the body is severely scratched and rubbed off. The phone fits well in the hand and easily fits into a trouser or shirt pocket. The front panel of the device is boring, as, in fact, it always was before the advent of the Edge model. As for the build quality, everything is at an average level. Creaks and slight play are noticeable, the body is far from solid and this greatly spoils the impression.

Controls and Ports

Almost the entire front panel of the gadget is occupied by the display. Above it are a front camera, a proximity sensor and a speaker. Below the display are the main control keys: a touch button for calling up a list of running applications, a physical Home button, and another touch button for going back one level. A headphone port (standard 3.5 mm jack) is hidden at the top end. At the bottom there is a port for connecting charging. On the right side there is a button to turn on and lock the gadget, and on the left there is a volume rocker. Slots for SIM cards and memory cards are hidden under the cover.

Communications

The smartphone is equipped with a standard set of communication tools:

USB 2.0 can be used in various modes, including Mass Storage (memory access from a computer);
Wi-Fi operating at 802.11 b/n/g frequencies. Supports Wi-Fi Direct fast data exchange technology (a tool that can replace the new generation of Bluetooth);
NFC - technology for data exchange and interaction with contactless payment systems;
Kies is a tool developed by Samsung that allows you to control data on your phone from a computer without connecting the phone itself with wires;
Bluetooth 3.0 is also supported.

Display

At the time of the gadget's release, the display installed in it was one of the best on the market, although it could not please with high resolution. The display has a diagonal of 4.3 inches and a resolution of 840x400 pixels. Given this ratio, the PPI number is disappointing, but this is purely a technical resolution. Overall the screen is much better, the picture is quite bright and sharp, the colors are oversaturated and catchy. The colors are unrealistic, but pleasing to the human eye. The screen consumes much less energy (energy consumption depends entirely on what colors are shown on the display; black consumes the least amount of energy). In the new generation of screens, the ill-fated PenTile (pixel arrangement technology) has disappeared, and Real-Stripe has come in its place, smoothing the picture. All this became possible thanks to the use of SuperAMOLED+ technology, which became the crowning feature of the Samsung Galaxy S2 i9100. The glass above the display is tempered, manufactured by Gorilla Glass. There is an anti-reflective coating, but it is of little use. The image fades in the sun. This device also uses VibeZ technology (this is tactile feedback when you touch the display).

Processor and graphics

The heart of the smartphone is a single-chip ARM Cortex A9 processor based on the Exynos 4210 chip (formerly Orion). The processor is equipped with two cores, the clock frequency of each reaches 1200 MHz. The built-in Mali 400 video subsystem is responsible for the graphics performance. The hardware platform is quite powerful and looks extremely promising, but, unfortunately, Samsung likes to fill their phones with a bunch of pre-installed and unnecessary software, and they are also developing their own version of the bootloader, called TouchWiz. All this negates hardware computing power. The phone is slow. It slows down in menus, in applications, and when scrolling through long lists. There is an excessive load on the processor, significantly heating it. Despite the above problems, the smartphone can still play most games, although not at the highest settings. In the synthetic Quadrant test, the smartphone scored 3121 points, outperforming all its contemporary competitors.

Memory

The processor is complemented by 1 GB of RAM (800 MB available to the user). In theory, on paper, this is a record, but in practice, it is a failure. Even this amount of memory is not enough to cope with Samsung firmware. TouchWiz does not spare a single megabyte and multitasking suffers greatly as a result. You can correct the situation by reflashing the gadget and installing “clean” Android on it, without the terrible Korean add-ons.

The main memory in the device is either 8 or 16 GB, depending on the selected configuration. In both cases, this volume can be expanded by installing a memory card. Cards up to 32 GB are supported.

Autonomy

The battery for Samsung Galaxy S2 i9100 has a capacity of 1650 mAh. An impressive figure for 2011. The manufacturer claims that the smartphone can last about 6.5 hours in talk mode and 350 in standby mode. Independent tests have shown that the gadget:

lasts about 12 hours in reading mode (e-book);
in audio playback mode about 19 hours;
When watching a video at minimum brightness, about 5 hours.

The results are not bad, but not the best either. To save more battery, you can use the built-in Power Save Mode utility. This is a kind of advisor that will allow you to configure your phone in such a way that the operating time on a single charge will increase, but this is not a panacea.

Cameras

Well, Samsung cameras can do something, especially in mobile gadgets. The Koreans were leaders in the industry 5 years ago and remain so. The smartphone is equipped with a main camera with a resolution of 8 megapixels and a front camera of 2 megapixels. Photos taken with the main camera are sharp, bright, saturated, without unnecessary shimmer, artifacts and excessive noise. Even in poor lighting, the smartphone produces a very decent picture. Other smartphones are not capable of this. Among the camera's features, it is worth highlighting software features, for example, filters that correct skin defects, panorama mode, searching for a smile and activating the shutter when one enters the frame, as well as the selection of different scenes (something like pre-configured parameters for different landscapes and light levels) . The front camera will please both those who simply communicate using it on Skype, and those who like to take selfies. It has much greater resolution, detail and viewing angle than many smartphones even today.

Sensors

Different sensors perform different quantitative measurements and convert physical indicators into signals that a mobile device can recognize.

Main camera

The main camera of a mobile device is usually located on the back of the body and is used for taking photos and videos.

Sensor type Digital cameras use photo sensors to take photographs. The sensor, as well as optics, are one of the main factors in the quality of the camera in a mobile device.	CMOS BSI (backside illumination)
Sensor size Information about the dimensions of the photosensor used in the device. Typically, cameras with larger sensors and lower pixel densities offer higher image quality despite the lower resolution.	4.54 x 3.42 mm (millimeters) 0.22 in (inches)
Pixel size The smaller pixel size of the photosensor allows more pixels per unit area, thereby increasing resolution. On the other hand, a smaller pixel size can have a negative impact on image quality at high ISO levels.	1.391 µm (micrometers) 0.001391 mm (millimeters)
Crop factor The crop factor is the ratio between the dimensions of the full-frame sensor (36 x 24 mm, equivalent to a frame of standard 35 mm film) and the dimensions of the device's photosensor. The indicated number represents the ratio of the diagonals of the full-frame sensor (43.3 mm) and the photosensor of a particular device.	7.61
ISO (light sensitivity) ISO indicators determine the level of light sensitivity of the photosensor. A lower value means weaker light sensitivity and vice versa - higher values mean higher light sensitivity, i.e. better ability of the sensor to work in low light conditions.	100 - 800
Diaphragm Aperture (f-number) is the size of the aperture opening that controls the amount of light reaching the photosensor. A lower f-number means the aperture opening is larger.	f/2.6
Focal length Focal length is the distance in millimeters from the photosensor to the optical center of the lens. The equivalent focal length is also indicated, providing the same field of view with a full frame camera.	3.97 mm (millimeters) 30.22 mm (millimeters) *(35 mm / full frame)
Flash type The most common types of flashes in mobile device cameras are LED and xenon flashes. LED flashes produce softer light and, unlike brighter xenon flashes, are also used for video shooting.	LED
Image Resolution One of the main characteristics of mobile device cameras is their resolution, which shows the number of horizontal and vertical pixels in the image.	3264 x 2448 pixels 7.99 MP (megapixels)
Video resolution Information about the maximum supported resolution when shooting video with the device.	1920 x 1080 pixels 2.07 MP (megapixels)

1) Large screen - convenient to watch the Internet, navigation and video, but hence the big drawback - wide, not ergonomic - see disadvantages. 2) fast navigation, quickly picks up satellites - and... the battery runs out quickly (see disadvantages).

I love my Galaxy S II! I've been using it for two years now. Before that there was an iPhone... A bright screen, a huge selection of free games and useful applications on web resources for Android and Samsung. Everything is convenient, everything is clear, everything can be found or guessed. Swipe the contact to the right - you call, to the left - you send SMS. Relatively lightweight, takes up relatively little space in your purse. And what a big screen! And how clearly he takes photos! You can't compare focusing with an iPhone! Video - just switches. On the iPhone, you had to pay for software to shoot video. I recharge the battery in the morning when I get ready for work. The battery lasts a long time. Standard SIM card. Beautiful animated screensavers - I have the weather right now: the weather outside the window is the same on the phone, although the phases of the moon do not change at night, in Linux on the laptop they change.

Bulletproof: DDD Well, of course, I'm exaggerating quite a bit, but the point is clear, I think) Gorilla glass does its job: on the very first day of use, I attacked the phone with a knife and poked at the screen. Not a scratch left (= - bright, pleasing to the eye screen - pleasant sound through headphones (I didn’t even try my own, which come with the kit) - the battery lasts long enough. This was one of the most important criteria when choosing a phone, so I was incredibly pleased. Depends on how many programs are running in the background at the same time, but usually with 2-3 programs (ICQ/Skype/reader) at medium/high brightness without GPS and Bluetooth always on, it works for about 8 hours Well, of course + music) - Convenient.

The external speaker during games (with the screen in landscape orientation) will close with your right hand.
- Slight “yellowness” of the display on the left side is a problem of most SGS2 (barely noticeable on a gray background, for example, after pulling out the top “curtain” to turn on/off Wi-Fi / bluetooth / GPS)
- Spots on the display that are visible ONLY on a black / gray background if you look at the screen in complete darkness (for example, pause the black YOUTUBE screen). Most likely a feature of the technical process of manufacturing the phone, they look like glue stains. Spots are not visible AT ALL during everyday use and do not interfere even at low brightness. To be honest, I completely forgot about their existence, but for a review you need to write everything as it is.
-Build quality. Not overall quality, but one moment. On the right side (slightly lower to

Battery (with active use it lasts 5-6 hours, sometimes even less, especially if you use 3G Internet), no indicator light, speaker (the sound is not rich, there is no pleasure when listening to music through the phone speaker), there is not a separate button for the camera , the contacts menu takes a long time to load (which is very strange), GPS (does not always work right away)

Poor shell of Samsung. The first two days I simply regretted that I bought the device: after HTC Sense it is impossible to consider it acceptable. On the third day I installed Go launcher EX and life was good. :)
- Delay when turning on the device is about one and a half seconds (turning on the screen): very annoying
- It often freezes, and you have to reload it hard, because... doesn't react to anything. More often this happens after being removed from the charger, but sometimes it freezes in standby mode, then all calls go through, but the phone ignores them and after an overload does not show in missed calls... Perhaps the problem is in some software, but that’s it same software (all from the market, no broken applications), HTC Desire was orphaned for months without failures.

1) the main drawback is a very weak battery, it lasts for 1-1.5 days, and if you don’t intensively watch the Internet, the screen eats up all the energy (see the report built into the smartphone about devices that use up the battery as much as possible - 70% of the total capacity is consumed by the screen) . The Nokia E52 smartphone I have works in phone mode for 6-7 days (!), and with music and navigation for at least 3 days - which is completely unattainable for the Galaxy II. And constantly thinking about recharging, carrying a charger or USB cable with you is unbearable.
2) too wide and thin, uncomfortable to hold in your hand, you can’t operate the controls with one hand at all.
3) the volume and power keys are often pressed simultaneously - they are located opposite each other, which is inconvenient.
4) applications consume traffic uncontrollably, turned everything off

The battery drains quickly (within a day) when wifi is on, but I have social networks (facebook, google+, vk) and email (mail and gmail) logged in + synchronization is enabled, + auto-upload of captured photos and videos. The solution is not to use wifi around the clock, but to recharge it when needed at home and at work. When taking photos, a pinkish gradient halo appears in the center, noticeable in average lighting - forgivable on a phone. There is a critical bug - if you go to the "Clock" in the evening and do not exit using the "Application Manager" - you can drain the battery overnight so that the alarm clock does not ring. I almost slept through important business trips a couple of times. I look into the Application Manager after the Clock and not only after it. Since the phone is used very intensively, it is sometimes necessary (once every 1-2 weeks?) to reboot.

Shovel-shaped: 3 my first thought when I saw it was: “God, I know how to dig potatoes in the summer.” The upper left corner is not used, so it is convenient to use in a vertical position, even with my microscopic palm.
- there is a delay when unlocking, sometimes the screen saver slips, but personally it doesn’t bother me very much.
- The sound button is located directly opposite the lock button) when music plays and you unlock it, I often change my volume, but maybe it’s just my clubfoot.

The screen is too wide for large hands. if your hand is small, it is not very convenient to reach the opposite side with your thumb
GPS picks up very slowly, sometimes it doesn’t pick up at all, even in open space

General characteristics

Type

Deciding on the type of device (phone or smartphone?) is quite simple. If you need a simple and inexpensive device for calls and SMS, it is recommended to choose a telephone. A smartphone is more expensive, but it offers a wide variety of options: games, videos, the Internet, thousands of programs for all occasions. However, its battery life is significantly less than that of a regular phone.
