I am using this phone since 1 month and I am not facing any problem with this phone.
At this time, this is the best phone at this cost offered by xiaomi.
It has a very good camera setup, in which primary camera is of 48 mp with a Sony IMX Sensor which is best in itself.
And three more cameras for macro, ultra wide and extra stuffs.
It has a 16 mp front facing camera which is excellent.
It runs on the Snapdragon 720g processor which is fast enough. That means we can play games like Pubg and Fortnight on this phone without any problem
It has a 6.7 inches full HD+ display, has negligible bezels and is bright enough with protection of gorrila glass 5.It has a 60 hz display.
Has a side mounted finger print sensor which is fast enough.
It has a 5020mah battery.
The thing I dont like is the charger, it supports only 18 watts charging which is good enough but not satisfying it takes arround 90 minutes to charge the phone to 100% .
I personally advice that one should purchase this phone it is worth of its price.
