I am using this phone for last three month. Probably the best phone in this price segment. I am using voice call, sms, and video calling very well. Camera quality is average. Front cam it around 1MB to 1.5 mb and in real cam it’s around 3 MB to 3.5 MB. It is volte phone. Jio 4G sim fully supported. It upgraded to MIUI 8 the changes are very good. Dubal Aap and dubal space very useful features in miui 8. 4050 mah powerful Bantry, 5.5 inch big screen, otg support, fast finger print senser, and very expensive looking phone.
