This is my first Xiaomi Mi4i, I was a user of samsung galaxy Grand 2 & galaxy E7.Mi4i excellent mobile.
Its flawless in every aspect.16gb is enough for storing 600 mp3 songs & 3 mp4 video.Many people complainig about heating issue.
Lets come to me perception , people who saying its getting heated up during 1st boot & setting up the phone for first time. I guess they haven’t use any smartphone either. Its obvious while booting for 1st time any phone will get heated up, Because all the app will be running alongwith wifi with highest performing speed to update apps, UI, screen will be light-up for long time.All in all, I would recmnd this phone to go the next step.
