Syncthing 1.26 crashing on Android in Syncthing-Fork

Catfriend1 · November 19, 2023, 12:17pm

So to sum up the issue: Some users are affected when Syncthing connects to another node.

A workaround has been discovered that pausing the folder on another node may avoid the crash on the Android side.

I’ve experimented a little with my phone and setup, but never got SyncthingNative to crash.

The relevant log had been provided here:
