Mi4 is a big industry but Mi4i is industrial floop. Fist scrub quality is excelent its one of the best display in midrange market I will give 5/5 to use it. Battery is also a plus point last two days of moderate usage 5/5 and next camera is very good best in class after moto x play in midrange 4/5. And here comes the MINUS points . first snapdragon 615 on mi4i huge mistake heated up very quickly but only if played games heavily 2/5. And secondly on sd card support is hell 0/5. Overall it good handset but not as good as other Xiaomi devices
