I’ve got a support ticket for Syncthing-Fork. Is this error expected to be already known and fixed in the latest v1.4.1-rc.3?
23:26:29 [GMFW6] WARNING: Database schema: leveldb/table: Writer: keys are not in increasing order: "\x01\x00\x00\x00\x00Camera/IMG_20181226_190237.jpg\x01\t\xe0h\x00\x00\x00\x00", "\x01\x00\x00\x00\x00Camera/IMG_20181226_160004.jpg\x01w\x92\x12\x00\x00\x00\x00"
Thanks for asking but no, that error looks like db corruption and there’s nothing to learn from that. In general I would suggest faulty disk or memory, on Android it might be anything else as well.
