Huawei is in the top mobile industry in the world. In quality building it is one of the best industry.
Im using this phone from a year now. I have a black glassy one. Which feel very good while holding in hand and comfortable too.
Camera is really good except in night.
The front camera is worst. My face looks oily and old. In the camera.
The phone has 3gb ram and sometimes it hangs. With the rom of 64 GB.
Overall the quality building is impressive.
