Wow, thanks for this important detail. I’ll be doing it from the Settings menu so I hope there won’t be any issues. I’ll report back once I’ve done it. EDIT: It worked without any problems. I disabled screen locks and the Google account (just followed the Android Central instructions) and voila, Bob’s your uncle.
Yup, I know a factory reset won’t revert it to stable. I’m happy with the beta because everything seems to be working okay. I can’t seem to get it to install security updates, but the app updates work. But it’s an older phone so I doubt I’d be getting security updates either way. Anyway, the person I’m giving it to will be using it like a dumb phone with a good camera, basically. Thanks for your input!
I’m signing as hard as I can!
