Hi, I am using this smartphone for last two months and its amazing. Smart features 1) Great battery life-stay for a day and half easily with full utilization where other smartphones stay only for 18 hours or less. 2) Finger print sensor-very easy and accurate, love to use it. 3)Ram and storage-very fast and lots of space. 4)Camera-it has a decent camera with HDRon and also front camera is awesome. 5)Software- It comes with miui 6 but it has been update on the same day to miui 7 which is very user friendly and smooth to operate.
