The phone is designed to work with 2 SIM cards. Medium in size, the case fits comfortably in your hand. The screen has wide viewing angles, which has a positive effect on image quality. RAM of 2 GB, built-in memory of 16 GB allow a powerful processor to download and install complex applications. The modern version of the OS makes the operation of the device smooth, without braking. Foreign users are advised not to update the system to 4.4, because "glitches", "lags" begin. The 13 MP main camera has a set of necessary functions for high-quality photos in any lighting. The second 2 MP camera takes selfies, helps to communicate on Skype. Internet access is provided via 2G, 3G, wireless connection. GPS satellites are caught quickly. I like the device for its performance, versatility. Among the "minuses": work in intensive mode is only 5 hours, so recharging is required during the day.
