I see some core team on this thread, so just wanted to say THANK YOU! Awesome job! Keep fighting for the users!
I'm totally the wrong person to offer recommendations on mobile, but so far it works very well for me, but then, I use almost no third party apps, and none of them are Play store only. My only complaint is the hardware (outside of their control).
I recommend putting proprietary Play Store apps grabbed with Aurora Store in the work profile with Shelter[5].

> It doesn't matter that the app is trustworthy, because F-Droid are extremely incompetent with security and the apps you install from F-Droid are signed by F-Droid rather than the developer.

They also say, if you use F-Droid, at least use F-Droid Basic:
> Dont use the main F-Droid client. Android is pretty strict about SDK versions and as F-Droid targets legacy devices, it is very outdated.

> If the app is only available on F-Droid / third party F-Droid repo, use F-Droid Basic and use the third party repo rather than the main repo if available. > > If the app is available on Github then install the APK first from Github then auto-update it using Obtanium. Be sure to check the hash using AppVerifier which can be installed from Accrescent (available on the GrapheneOS app store).

By the way, while GrapheneOS recommends Accrescent, I don't use it anymore because they can't even add apps like CoMaps, while some of the apps they actually added are proprietary.
Having recently gone through the F-Droid release process, I learned that this is not necessarily the case anymore.
F-Droid implements the reproducible builds concept. They re-build the developer's app, compare the resulting binary sans signature block, and if it matches they distribute the developer-signed binary instead of their re-built binary.
This is opt-in for developers so not all apps do it this way. I'd sure like to know how common this is, I wonder if there are any statistics.
The process adds a significant delay for updates but it does not actually protect users from developers in any meaningful way. This real world example with WireGuard demonstrates that.
