Announcement by the creator: https://forum.syncthing.net/t/discontinuing-syncthing-android/23002
Unfortunately I don’t have good news on the state of the android app: I am retiring it. The last release on Github and F-Droid will happen with the December 2024 Syncthing version.
Reason is a combination of Google making Play publishing something between hard and impossible and no active maintenance. The app saw no significant development for a long time and without Play releases I do no longer see enough benefit and/or have enough motivation to keep up the ongoing maintenance an app requires even without doing much, if any, changes.
Thanks a lot to everyone who ever contributed to this app!
LineageOS, maybe? Still Android, but (AFAIK) more open to change than standard Android.
I’ve been using custom ROMs for a while now, but the reality is that they can only do so much to stop Android’s ever increasing restrictions.
And the aforementioned Integrity API also detects unlocked bootloaders, meaning this will gradually become more of a problem.
