I have been using this phone for about 2 years( since May 2015), and I am really satisfied. The battery never drain fast, and I rarely have to use powerbank. I dropped it really often, to the extent that I dropped it 2 times a day, but it still works fine. It rarely lags, the primary camera is really good, but the secondary camera doesnt really works that well indoor. It works well when theres a bright light. The size is perfect, not too big, not too small, so its easy to type with this phone. I recoomended to all of you to buy this and enjoy. thank you.
