In contrast to the current trend to produce more smartphones, ASUS did not forget about the other users who are not so important large screen. The main advantage of small smartphones - this benefit, it is not necessary to get used to, in contrast to the 6-inch phones and comfortable to work with one hand.
Thickness 12 mm smartphone, but it is not strongly felt, as the phone thinner towards the edges. Due to the geometry of the rear part of such a smartphone repeats grip palm and phone fits well in the hand.

The back cover of the smartphone is made of opaque, slightly rough plastic. Coverage is pleasant to the touch and does not collect fingerprints.

The cover covers not only the back portion and lateral faces, ie volume buttons and lock are on the panel itself. Such a decision has the effect of solidity and disposable smartphone. But the back panel can be easily removed and provides access to the removable battery, microSD connector and two SIM-cards.
Panel holds fast to a large number of latches, no creaks or wobbles.

In addition to white, there are models in other colors: black, red, yellow and turquoise.

When you receive different notifications such as missed calls or messages, the indicator will blink green. Smartphone notifies the low battery capacity and charging process smartphone. To the right of the front camera is a proximity sensor to lock the screen during a call. Alas, we have a budget unit and the light sensor is not available, so that the brightness will have to be set manually.

Below the screen are the usual touch buttons: back, home screen and application manager. The sensor is quite sensitive, lights in the buttons missing. The system can adjust the vibration when pressing these buttons. By the way, the vibration is very strong and well felt even while walking.

The right side is the volume rocker, a little higher - release button. The button layout is not the most comfortable, with my thumb-grip lies just on the volume up and have to get used to that release is higher. Buttons themselves are corrugated texture and nicely pressed.

The microphone is located on the bottom.

Connector for charging and sync micro USB placed on the left side.
It supports OTG, ie You can connect flash drives and various peripherals. Unfortunately, microUSB-OTG cable not included, it will have to buy separately.

But technology does not stand still, and TFT-screens every year look better and better. The screen resolution of 800 by 480 pixels, 223 pixels per inch (PPI).

In the sun, the image is bad and has to be seen to exhibit a maximum brightness. In general, the screen looks good, the colors are true, the viewing angles are not too large, but more and we do not expect from such a budget phone.

The screen has a protective coating during use no scratches appeared. Also there is an oleophobic coating, whereby the finger glides well and remains less prints.

The screen supports up to 10 simultaneous touches.

The camera switches to the search parties. If you select two faces, the camera does not recognize until the second person in the picture, a picture is not going to happen. The whole process is accompanied by an audible indication, for example, if the second person in the picture is not horrible, it will be signaled. After the photo was taken, you can choose a good picture of the three proposals. You can then immediately processed photos - to correct tone, do more to narrow the eyes or cheeks. In general, the girls will be happy.

Battery operating time and h4> Removable lithium polymer battery has a modest capacity of 1600 mAh, but for the small screen and energy-efficient processor that's enough. In the settings you can select the different modes of the phone that will extend the life.

In power saving mode, the device will include a wireless connection only with the active screen. Using the optimized mode, I have not noticed any restrictions, everything works as usual. You can flexibly adjust the backlight for video or Web sites to set permissions for the use of the Internet messenger.

In the evening I fully charge the phone and leave it on overnight without charging. In the afternoon I used Wi-Fi just over an hour to see the sites. Also included was constantly mobile internet, regularly have Viber messages and Gmail auto-receiving letters and not checking the box at a certain time. The voice call has been made about 25 minutes. By 8 pm the phone is almost completely drained.

In general, the result is quite good, like most smartphones, the phone runs a "light day».



Conclusion h4> So, in the ranks of the budget smartphone will sign a representative of this class. For 3990 rubles we get a compact and convenient smartphone with good performance. Though the screen resolution is not that big, but for the diagonal of 4 inches is enough, the picture looks good. Also unusual was seen here the protective glass.
