It should be noted that the device can have one of three colors of back cover: white, orange and yellow. In this case, complete with a smartphone, as mentioned above, there is a second cover. It is in any case in black, so that even when buying a smartphone with the main cover is yellow, you can easily turn your smartphone into less bright and eye-catching among others due to the black cover. It got us to the test version with a white cap. All variants covers are made of opaque plastic.

Covers the front surface of the protective glass. In its upper part is the voice speaker, under it – the manufacturer’s logo. The bottom face of the microphone. Along the contour of the protective glass is a plastic frame, it does not act on it. Housing sidewall chamfered towards the rear side. Left lateral face devoid of any government, but on the right is a button and volume control. By the way, because of the sloping sides are pressed, it is not as clear as we would like. The upper end has a 3.5mm audio jack at the bottom – Micro-USB-connector. On the back of the phone is located a 5 megapixel camera lens, the manufacturer’s logo, and at the bottom – hole multimedia speaker.

RAM is only 512 MB , the volume of the built-in 8 GB of storage, which, if desired, can be increased using memory cards microSD. Complaints about the work of no wireless networks. GPS satellite reception speed is very good and almost envy from having internet connection.

In terms of performance, critical issues were found. But when you run standard applications, such as camera, for example, some setting items, not to mention third-party applications, you can see the message “Loading” or “Renewal.” In principle, this can be attributed to the slowness was a small amount of RAM. In the rest to us quite nimble machine.

High volume of both speakers, but at a high volume multimedia speaker starts to wheeze. The headphones sound good. Not being an expert in this field, I can only say that most users enjoy the sound. But the standard means of recording the conversation with no line, but it can be fixed by downloading the appropriate application from the store.

Despite having two SIM-cards in the smartphone just one radio set because of what you speak to one of the SIM-card second becomes inaccessible. If the hardware implementation, understanding, here’s the software implementation of the two cards is interesting. On the main screen there from two tiles messages and call log, that is one tile for each SIM-card. You can quickly switch between them. On the one hand it is good. Especially for a better separation between personal and work number. If this is not necessary, then why not get used to such implementation.
