Seems like I’ve found the culprit: https://github.com/Magisk-Modules-Alt-Repo/trichromelibrary-squoosh

When I deactivate this module and try again, the error message disappears and shows up again when enabled.

Happy to hear that it changed for the better. I’m still on Android 10, where it sadly isn’t the default. But thanks for letting me know :)

I’d prefer that notifications are blocked by default (should be opt-in instead of opt-out). The only apps I NEED notifications for, are messaging apps, everything else is just annoying.

I don’t want bloatware and Google services on my phone. I want to install magisk modules and use root. If a phone doesn’t allow unlocking bootloader and doesn’t have decent custom rom (or GSI) support, there’s no way I’m buying it.

That’s what I’m using:

I would advise to use open-source software wherever you can. You (almost) never have paywalls, ads or trackers there ;)

You can use an OTP Generator like Aegis Authenticator from F-Droid. Afaik it even works offline, so there should be no risk if you strictly keep it offline.

Sounds interesting. Do you have a source for the mentioned research?
