With the official app no longer updated (i don’t trust the forks), i’m looking for alternatives for 2 way sync between my Android phone and my Linux server. I’ve tried nextcloud a long time ago and the experience was very bad. Are there any new tools that i can use?


Build a Syncthing Android apk yourself. You don’t need to update to every release. I’m still using 1.30 with 2.x.
Its only a matter of time before they push a backwards incompatible change that causes older clients to stop syncing, Or a security bug is discovered in the older code.
And when they do, you take care of it. Also, if you use Tailscale or equiv, you can stop Syncthing’s exposure to the internet. Then you can stay on a fixed version across clients and limit unexpected breakage that comes with autotomatic updates.
