it's been two months that I have, and there are no operational problems. The battery does not drain so fast that it finally. Everything depends on the use made of it. It charges quickly and more. The image quality of the video is good. The Bluetooth works well and connects very quickly (in car). The screen resolution and brightness is excellent too. We see the screen even outdoors in bright sunlight. This smartphone is very light, I quickly bought a case to protect it. I'm not disappointed at all to have bought!
