#redminote7

I have encountered this error in many rom of redmi note 7 Specifically. when I use my phone before the alarm starts ringing, the notifications will no longer be displayed. No button to turn off. The bell kept ringing. I couldn't do anything but restart the phone I hope the admins will fix this...

Hello guys. I'm in a doubt here. If I want to return to my Stock ROM...is it obligated to do it via MiFlash? What other reliable methods and procedures I could use to go back to my stock ROM. Shall I use the fastboot ROMs or the Recovery ROMs? My device is a Redmi Note 7 currently running MIUI...
