I understand political dissidents and those living under authoritarians may have much more concrete Fs and Ds but for me (us?) it's mostly U.
I do. It's my device. And I've been in the position of having to buy a replacement phone in a pinch; having to wait an extra day before having a usable replacement is not acceptable.
In terms of apps I might not be able to get from the Play store:
- Signal, depending on what country I'm in in the future and whether they've tried to restrict things they can't backdoor.
- Vanilla Music, which remains the best music player I've used. (I wish there were an Android version of Quod Libet.)
- A fully capable version of Termux. (the Play store currently has a less capable version that's maintained separately, which could go away if someone decides to stop putting up with it).
- Syncthing-Fork, which has at times been undermaintained in the Play store.
Update: out of the box it seems to be reading tags strangely. Maybe I could fix this studying the settings more, but I'd say you have an upgrade opportunity switching off Vanilla. Signal is hard to replace though.
Just see the Play Integrity API making the user experience more difficult on more secure devices like GOS with mo security benefit.
>Play Integrity permits a device with years of missing security patches. It isn't a legitimate security feature. It checks for a device in compliance with Google's Android business model, not security.
