I used this device for 4 days and from experience I can say some specs of this device.
A very capacious battery, which is difficult task to discharge in a day. The device discharged in one day. The charging speed is super fast. I charged this device in half an hour. The quality of display is fantastic. The color accuracy is awsome. Watching movies and videos on it is pleasure. Quad camera performs very well in low light also. Front dual camera features also great. You like to take selfies then this device is yours.
Facial recognition and in display fingure print scanner works pretty fast.
Premium in hand feel and
No heating issues at all.
