I buy this phone 2 weeks ago and tested everything.First of all its build quality is fine really good efforts by xiomi it gets little bit of curve which makes it easier to handle.The fingerprint sensor works really good, very reponsive. I’ve purchased 32 gigs of memory and 3gb of ram variant and it work really fast. I dont feel any lagginess in the phone it every time frees up the ram to open apps really fast. Xiomi has given up many sensors in this phone like gyroscope, AR blaster, FINGERPRINT SENSOR and many more and it really works fine with VR, yes I’ve tested it many times. Massive 5.5 INCHES screen gives it that great looks and screen resolution is also very adequate.In terms of calling it feels OK and yes I have also tested jio sim in this headset and it supports VOLTE and works great. And in terms of battery it comes with massive 4150 mah battery which gives excellent screen on time, great work by xiomi in terms of battery. OVERALL BUYING THIS PHONE VALUE FOR MONEY.
