The Xiaomi MI4i build: notification led, 3 capacitive keys, speakers, dual micro sim with 4G support. The 5 inch 1080p display is really good. Good blacks, colors, good viewing angles and looks good under sunlight as well. The phone runs very smoothly.
The phone doesn’t heat much for me in balanced mode. Call quality was good, the speaker was fine but I believe it can be better. The phone lasts me a day easily. The camera pics were crisp and colorful. The UI is simple and easy to use. Lots of features. Runs lollipop preinstalled. Everything can be themed via the mi store which some thing that doesnt exist in many phones. The storage is 12Gb usagable out of 16gb.
