I am using the Redmi 4(3G 32 GB) model since 2 months and it is working smoothly. It’s snapdragon 435 octacore prossessor is blazing fast for multitasking and daily usage. It’s 2.5d curved 5" hd display produce sharp images. and it’s sound quality is nice and the metal unibody phone’s build quality is superb and looks premium. The main highlight of the phone is it’s 4100 mah big battery which gives enough juice for the day. actually I loved it.
