Recently I installed the MIUI 11.0.2 Global on Redmi 7A and found a bug on microphone. The microphone randomly freezes and stay mute in all apps until the next reboot. Some time later the mic freezes again. Reading in web found the same problem with other phones, and it seems a problem with Google Assistant app when it is active. I have deactivated this app and the problem seems fixed until now. I hope this can help on improvements.|
