After updating my Mi4c to 5.12.31:
- Google Search app was removed from the phone
- WPS Office app was removed from the phone
- Constantly getting a reminder to sync Mi Cloud
Nevertheless great rom and great battery time! :)
I'm also running 5.11.5 on my Mi4c and:
- Wifi (including switching on/off) is working perfectly
- No problems with ram. After cleaning ram, about 1.8 gb available
- Watching video on browser is working OK.
