1. you don't own mi4c so you knew nothing about this ****** phone
2. i never say i don't like miui eu rom
3. i already own other phone
here is some constructive answers, just for you:
1. miui7 - good SOT, phone is often overheating and drop in performance
2. miui8 - worst SOT, phone is overheating, I feel myself like a human torch even when I am playing simple games
3. miui 8.3 (Android7) - even worst SOT, problem with whatapp notification, playstore, not so good gps, camera is worst then miui7 ...
4. with every update this phone became worst
5. this phone should be renamed in Mi4m (m=mistake)
sorry for my bad english, it is not my native language.
