I want to tell you features and drawbacks of Xiaomi Mi4i phone. By design it grabs your attrection. It has 5 inch screen . It comes with 2 gb ram. It has HD display with resolution of 1080 pixels by 1920 pixels at a PPI of 441 pixels per inch. It supports 3G and 4G but it not support VoLTE . It means if you are using JIO SIM then for calling you have to download JIO calling app because has no any support to VoLTE. Even it has no provision to expand its memory. Overall it has all required functions except VoLTE and expandable memory.
