This product interesting, first of all, for its pleasant design, excellent camera and a wonderful screen with an IPS matrix. Its name is Lenovo IdeaPhone S820. Let's take a closer look at this device.
Equipment
In addition to the phone, the box with the standard package contains a quite ordinary set of accessories: Charger, 2000 mAh battery, microUSB cable, headphones and a set of documentation with a warranty card.
Video: unboxing a smartphone
Specifications
The filling of Lenovo S820 consists of a quad-core MTK6589 processor, each of the cores of which operates at a frequency of 1.2 GHz. There is also 1 GB of RAM and 4 GB of internal storage. There is support for microSD memory cards up to 32 GB. The battery in the device, with a capacity of 2000 mAh, lasts for 2 days autonomous work... The thickness of the case is 8.9 mm, which is perfectly acceptable with a screen diagonal of 4.7 inches.
The overall dimensions of the device are 139.5 x 69.5 x 8.9 mm. The phone has 2 SIM card slots. One of which supports GSM and WCDMA modes, and the second only in GSM.
Lenovo S820 comes preinstalled with operating system Android 4.2. By tests Antutu Benchmark 4.0 the device scored 13137 points, which is an excellent indicator for a device of this class.
Screen
Screen resolution this device is 1280 x 720 pixels (HD), which is excellent for a 4.7-inch diagonal. The matrix display of Lenovo S820 is made using IPS technology and has quite wide viewing angles and is perfect for surfing the Internet, watching movies and playing games. The sound in the phone is good, but not loud enough.
Camera
The smartphone has 2 cameras. The main one has a 13-megapixel sensor and takes excellent pictures. The front one is 2 MP and is ideal for video calls.
Video from the camera:
Appearance
The phone looks modern and stylish, it comes in two versions - red and white, which most likely positions it as a female model. On the front side there are Lenovo logo, speaker, light and proximity sensors, 4.7-inch screen with IPS matrix, and under it - three touch buttons navigation.
The back of the Lenovo S820 is made of matte plastic, which houses a 13MP camera with flash, Lenovo logo and speaker grill. There are no elements on the left side.
Accelerometer(or G-sensor) - sensor of the device's position in space. As a primary function, the accelerometer is used to automatically change the orientation of the display image (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled various functions devices by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure angles of rotation in several planes at the same time. The gyroscope together with the accelerometer allows you to accurately determine the position of the device in space. In devices that use only accelerometers, the measurement accuracy is lower, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- a sensor, thanks to which the optimal values of brightness and contrast for a given illumination level are established. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental presses. The presence of the sensor allows to increase the operating time of the device from the rechargeable battery.
Geomagnetic sensor- a sensor for determining the side of the world to which the device is directed. Tracks the orientation of the device in space relative to the earth's magnetic poles. The information received from the sensor is used in cartographic programs for orientation on the ground.
Sensor atmospheric pressure
- sensor for accurate measurement of atmospheric pressure. Part of the GPS system, it allows you to determine the height above sea level and speed up the location.
Touch ID- fingerprint identification sensor.

Satellite navigation:
Gps(Global Positioning System) - satellite system navigation, which measures distance, time, speed and determines the location of objects anywhere on Earth. The system is designed, implemented and operated by the US Department of Defense. The main principle of using the system is to determine the location by measuring the distance to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from its sending by the satellite to being received by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The measuring principle is the same as the American system GPS navigation... GLONASS is intended for operational navigation and time support of land, sea, air and space-based users. The main difference from the GPS system is that the GLONASS satellites in their orbital motion do not have resonance (synchronization) with the Earth's rotation, which provides them with greater stability.

I have been using the phone for a month now and this is what I understood. Of the good, I was very pleased with the screen, it responds very well, and the quality is just on the highest level, the picture is beautiful. It loads toys without problems, what just amazed me was the very settlement of the themes. Desktops and in general a lot of things, it feels like I can change everything at all) The android system under the cover of Lenovo makes the design very unusual and eye-catching, the camera shoots at 13 megapixels and this raises it very much in the eyes of others

trouble-free, fast, excellent camera day and night, excellent communication (both the interlocutor and me can be heard without interference, as if we are nearby), a strong body and tempered glass - checked with a nail, double-taped lock on the screen - who had a Nokia N9 - will understand which convenience, it’s impossible to list everything. Little things make up what you need a smartphone for.

The price, an excellent screen, does not slow down, there is enough for those who like to play, GTA VC, RR3 - all this without brakes, a battery, a good case (without backlash), there is nothing to hold together and not leave. An update to version 4.4 will be released soon. Two SIM cards, there will be no problems with the Internet =)

Battery, for such a large screen it is better to buy another battery, it can last 2 days, but you often have to put it on saving mode and not enjoy all the features. Such as keyboard vibration
Memory here I was very dissatisfied. Written 4 got 2, good luck there is an input for a micSD card, it saves him.
The camera, despite its 13 px. The camera creates stripes in a dark place and every time it is rather unpleasant than not so, here the camera is saved by the macro, which is at a height
There are errors in the system in operation, I think with the firmware it will all go to naught
It's not "Garilla Eye" you don't even need to check, it's better to buy a cover

This is software. For example, you cannot switch from application to application through the menu, as on a tablet. You have to go out and go back in.
Sound profile settings. You can't create your own under your own name, like any Nokia models for example. Plus, other options could be tied to the profile.
The amount of free memory turned out to be 2.5 GB. The flash drive through the computer is seen on 4 GB (available memory). The remaining 4 GB is most likely not available and is used for some other purpose.
3G works only in the 1st slot.
I would like to support an external memory card for 64gb.
Let them buy smart cards for 20,000 tr such as HTC or GNUSMAS, and everything will be OK.
