Very high quality display, pleased with their own brightness and saturation regarding energy savings - to be honest, not AMOLED saves. The camera is very high quality, detailed photographs and transmits the natural tones of the subjects. The case is very glossy but it has a beautiful metal texture blue. The processor and memory loads in moderation, glitches are not particularly noticed.
The battery is weak, even if you disable wireless functions and not use a phone, he manages a night to lose up to 10%. Cleaning RAM doesn't help, the user interface is voracious. Very often experience that the phone turns off completely discharged. Shorter, battery lives his life.
Despite the bad optimization of resources and the power of the unit, the functionality and design very much. The sound is louder than the HTC Desire HD.

On a scale, put a solid four-plus

Operating system Android, imputed price for the smartphone, big sensitive screen,good sensitivity and color reproduction, two slots for SIM cards
Quickly run out of battery, sometimes hangs(with a large quantity of open programs), no stylus
This machine was purchased four months ago. Plenty of his time, I will experience future users. Looking for a smartphone for good price. This smartphone has stopped because it has an optimal ratio the price-quality(my personal opinion). The unit itself has a black body colour, comfortable for the hand. The case is durable, fell a couple of times, once on asphalt. The screen is large, clearly visible in the sun, bright color and good contrast. After purchase, it is better nucleate protective film tends to scratch. Sensitivity to finger pressure is normal, sometimes the truth is not very convenient to use when the bumps in the road. OS Android, compatible with Google and its services, you can download games, movies and other nonsense. With prolonged use(toys, movies), if the battery is new, charge lasts for a day. I have now the charge lasts for half a day, slightly killed the battery. Charging long, around 6 hours, this creates problems when using, you need to adjust. The processor is fast, pulls all the latest games and movies. Of RAM enough, sometimes the truth is a bit tricky, if you open a large number of programs. Has all the modern bells and whistles, GPS, WI-FI and stuff, I really don't use a half. But it's not for everybody. There is a built in function for tracking of a smartphone, especially for those who lose their. Two slots for SIM cards, convenient for those who have two operators.The phone overall is good, very easy to use, kids love to play.

Dual SIM card - for me, defines a "plus". Nice design, the phone itself is light and compact. In a woman's hand lies well, though one-handed use difficult. HD display, very good brightness, blinding sun outside can clearly see the screen. Acoustic system: both with headphones and without them the sound quality is great (to a certain volume level). Standard headphone Jack. Very fast, almost the moment (unlike the vaunted iphone) catches Wi-Fi. A large amount of internal memory.
Plastic housing - no cover will not live long. Microsemi operator changes for free, but this time. Flimsy the volume button. A lot of pre-installed software, personally I don't need - and cannot be deleted. At high volume the speaker starts making a creaking sound. The battery capacity has been catastrophic. Even a single smartphone did not sit down so quickly. Not enough on the day.
Overall phone for its price range is very good. Quickly run out of battery - but it is rather a side effect of two SIM cards. Pleased with camera, video. Only on the third day of use had the volume button. The seller replaced without question, probably not my one have this situation with this button.
