The latest Android app v1.16.0 frequently crashes on my Android 11 (May 5, 2021 security update) phone. The Syncthing app has been remarkably stable and smoothly functioning for years, so I am surprised by the behavior. I installed it via F-Droid.
I can’t find anything useful in the logs. There is a line like this
--------- beginning of crash 06-04 22:04:06.366 I/SyncthingNativeCode(28084): [start] INFO: syncthing v1.16.0 "Fermium Flea" (go1.15.9 android-arm64) vagrant@basebox-stretch64 2021-04-26 13:38:08 UTC [noupgrade, stguiassets, sthashing, stnoupgrade]
but no further information beyond the usual startup messages from when it restarts after the crash. I cannot determine what actions or circumstances lead to a crash; it seems random.
