A manufacturer’s Android can have special privileges for their own apps, and almost will certainly have special privileges for Google’s apps.

Graphene by default wouldn’t give special privileges to any app, so that’s at least a plus.

It’s true that it would be locked down, but you at least have a couple more controls over how locked down compared to a manufacturer’s OS.

That’s odd, I’m on Android 14 and have andOTP installed.

To add to what the other person said, there are some Windows-only games even today that run better on Linux than on Windows (I don’t have examples off the top of my head.)

It depends on the place. There’s a grocery store I go to (in Seattle, WA) that has a $100 limit for mobile payments.
