It happened totally random, I was about to charge my phone from 8% to 100% to calibrate the battery, first I restarted it to refresh everything, then I noticed, that the flashlight is greyed out. I thought first, that the battery level is just low. After fully charging it, I noticed that much more is bugged, soft reset doesn't help, only a full wipe and ROM reinstall.
Happens since yesterday, do a backup of your stuff, make screenshots of your settings. The only known fix right now is to reinstall the ROM. ROM update is not enough.
It's weird, it feels like a timebomb since it happened to a bunch of almost at the same time. It screams of certificates expiring somewhere.
I CONFIRM same issue on Poco F5 Pro (Mondrian) running latest MIUI.eu Weekly build two days ago. Non-rooted or modded device.
Don't know about deactivating stuff, a clean install fixed all of the issues. That's all I had to doI guess the course of action at this point is to reset the phone / reinstall the ROM and deactivate Google Play system update in Settings > Google > three dots in the top right corner > System services updates > toggle Automatically install system service updates.
And wait for a fix in the next iteration
However, the phone will download this update again automatically. How can I stop it?
in Settings > Google > three dots in the top right corner > System services updates > toggle Automatically install system service updates.
I am sorry that I can’t find it in mi 12s pro v13.0.18. When I click three dots in top right corner, it didn’t have system service updates choices.
That would be because when you reinstalled, you went back to a previous version of Google Play system update, but my guess is, if it tries updating again, it waill fail again sooner or later.
