I've been using mi4i for 22 months. Performance of battery display camera etc ( bought mi4i only since it was getting nice reviews for these) are same as when I bought . One thing I should mention here is that I frequently use 4g hotspot for 9 hours a day (25%charge would be left after that) in my phone for office use. Watch a lot of movies in it. Still the phone is awesome. I have dropped my phone numerous times. But nothing happened to the display.
Indeed there are some annoying bugs in miui. They are tolerable comparing with quality of phone. This is my first smart phone. I hear people who bought Samsung phone saying phones get hung and not so good camera quality. I started to wonder if there such thing as those. I really couldn't believe a phone can get hung. Just because of my experience with mi4i.
Justin, 23 Nov 2016Hi this is Justin here. Guys I want to tell u all that I am using mi41 for one and a half year... moreCall dropping is because of buggy double tap to unlock feature in miui. If you disable it call drop issue will stop.

Install a battery saver from google play store and use it to conserve the battery. It isn't a problem.

Since 4 years, I only buy Xiaomi ( bought in Beijing and After by internet on Belgium. Two years ago, I've been obliged to buy a new one in Hong Hong. They only have mi 4i version, a low cost for India ( in a Xiaomi shop _ thus not a fake ). It works perfectly. Thé pictures are wonderful, many of them nicer than those made with thé expansive caméra Canon of my husband.
