DESIGN USE
The back panel of the device is made of glossy plastic with a small hole for removing the cover. The surface easily acquires fingerprints and other traces of use. Below is a row of holes for speakers, on top is the main camera module along with a flash and volume buttons. There is also the Asus logo. The perimeter frame is made of smooth plastic and is easily scratched.
There are three touch-sensitive buttons on the bottom of the front panel: home, back and recent apps. On top there is a front camera module, a speaker for talking, a logo and a battery indicator without any other functions. On the top there is a power key along with a headset jack, on the bottom there is a microUSB port and a second spoken microphone. At the same time, both sides of the Asus Zenfone GO do not have functional elements.
available in a variety of colors
Available in several colors: white, gold, dark gray and red. Under the cover there are slots for two medium-standard SIM-cards and a memory card. The kit includes only documentation, a charger and a USB cable.
Uses a TFT type matrix with a resolution of 854 × 480 pixels. At the same time, the viewing angles are quite small, which is typical for this type of screen.
Qualcomm MSM8212 Snapdragon 200 - not all games work
When viewed from the side or from above, the colors are significantly distorted, but when viewed directly, the detail is quite good. The quality of the color temperature is also at an acceptable level. Outside the home, the maximum screen brightness may not be sufficient to read text.
colors dimmer than all IPS displays The display distinguishes no more than five single presses. Images of photographs or pictures have sufficient elaboration.
The Asus Zenfone GO is equipped with a 5 megapixel main camera with f / 2.0 aperture and multiple shooting modes. In addition to the presence of HDR, it is worth noting the "low light" function, when activated, photos at night are noticeably better. In addition, this smartphone is well adapted to various shooting conditions thanks to the PixelMaster technology. Despite this, practice shows a rather mediocre quality of photographs, especially if they were taken indoors. In daylight, detail and brightness are significantly higher.
the kit includes a power supply and micro USB. Headphones missing
The front camera has a resolution of 0.3 megapixels and is just as poorly suited for Skype conversations or selfies. However, there are several functions for correcting photos, for example, you can remove some skin imperfections and level facial features.
POWER-MEMORY
It uses a quad-core Qualcomm MSM8212 Snapdragon 200 processor. Under heavy workload or using "heavy" games at high settings, the device heats up quite a lot, but this factor is absent during standard use.
two slots for micro SIM cards and a slot for microSD
Asus ZB452KG is based on the Android 5.1 operating system. The amount of built-in memory is 8 GB, of which about 4 GB is available for use.
battery 2700 mAh For RAM, 1 GB is allocated, there is support for the 3G data rate standard. It is also possible to expand the internal memory using microSD with a maximum capacity of up to 64 GB.
OUTPUT
He is a representative of the budget segment with the appropriate characteristics. There are quite a few color options, as well as support for 3G data rates. The display quality is not bad in practice, but use in sunlight or high angles becomes difficult. The battery capacity is enough to use the functions of the smartphone all day long. In addition, the main purposes in the form of calls and some actions with the Internet are performed quite quickly. There are a large number of different sensors.
Nevertheless, the declared characteristics are sufficient only for the most simple tasks or games with minimal requirements. With the main camera, PixelMaster technology dramatically improves the situation, so the lens can be used to capture simple moments. Due to the small amount of memory, it is necessary to use a memory card to store more capacious data. Thus, the Asus ZB452KG phone is well suited for undemanding users or minor tasks.

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 by various functions of the device 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. Devices using only accelerometers have lower measurement accuracy, 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 are established for a given illumination level. 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.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system that 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) is a satellite navigation system that 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 similar to the American GPS navigation system. 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.

Colorful state employees always delight, because on the one hand they are available, on the other - the number of available color solutions will always find buyers who prefer to stand out. In addition, there are not so many color solutions: among the proposals, the only thing that catches your eye is the Zenfone Go line. The Asus company decided not to break the established tradition and presented a completely budgetary phone Asus Zenfone Go ZB452KG.
What's new in appearance
Those who are familiar with previous samples of the fifteenth year, for example with smartphone Asus Zenfone Go ZC451TG, they will immediately note that the navigation element, characteristic of many smartphones of the company, has returned to the back panel - the volume rocker. The rest of the design is familiar: in the middle the device is plump, the back slightly protrudes, which is what users of other Asus in arched design are used to. But the edges taper to 3.6 millimeters.
Below, under the display, you can see a proprietary metallic overlay, the power button is located in the center, on the upper edge. By the way, many users will want to buy a smartphone, not only because of the budget price tag: this is the rare case when the diagonal is 4.5 inches, which were usual for past years. But the resolution is only 480x854 pixels. Returning to color schemes, it is worth noting that there are seven of them. Bright tones look especially cheerful: scarlet and lemon.
Technical capabilities
Given that we have an affordable device, one should not expect that it grabs a star from the sky. Responsible for performance is the 200 series snapdragon, which can be considered basic, given the characteristics of expensive devices. For example, a competitor Lenovo A2010 got a media-tech processor, so Asus Zenfone Go ZB452KG looks preferable. There is only 1 gigabyte of RAM in the device, but given the unproductive platform, which is enough for non-gaming everyday tasks, there should not be a lack of RAM. The main memory is also small: only 8 gigabytes, but there is an expansion slot and 100 gigabytes of cloud storage. The main camera received a five or eight megapixel sensor, depending on the version, and surprisingly fast optics with a 2.0 aperture. Be that as it may, this is a smartphone with widespread wireless capabilities: surprisingly even support for glonass and bds is announced.
