I like mi phones very much
But I found some things are missing in mi phones

1 device not connected to LED TV or car music system as a USB device other device have already this features supported.
2 mostly device of mi is dual sim supported.
But not separate ringtones set option for different sim.
3 Application search option. This task is not easy in mi phones for choose a application find page by page.
Mostly in other device just tap down and search whole data of mobile like apps, songs,video, contacts SMS and all that.
4 My mi5 device I faced Bluetooth problem when I play songs via Bluetooth. It's range is very low
