If you have no serious problem to share your not-working "database" folder with me, it will be more than welcome.
@menion - /data/database/track.db is 164MB. Do you want it or could I ideally just ZIP the remainder of /data/database/* to save upload time?
3.49.1.4 - menu > More - nice. But why is "Quick action menu" listed with "Beta - testing"? It's been around for years.
3.49.1.4 - BRouter Updater download now working. Do you plan to have Minimize button similar to Sync so that operation can continue in background, then view progress via notifications?
This comment is not directly related to LM4, but when you select Backup manager > Restore, the initial File browser directory is the root of the internal file system, which seems an odd place to be placed. I then select the "Internal storage" directory. Would this be a better default?
Regards manual Cloud Sync: would it be possible to display summary of sync operations that will be performed for confirmation
before proceeding further? When I see a brief message "deleting points" or "deleting tracks" with no mention of what, I get concerned. Maybe the summary could list the points & tracks which will be sync'd & whether the action is new, update or delete. I just did a manual Sync of (slave) tablet data; it appears to have performed fast & correctly. AFAIK anyway ;-)
PS. Quick settings don't appear to be backed up or restored. I did a settings backup from (master) phone which has a Quick settings panel. I did a settings restore to (slave) tablet & Quick settings appear to be the defaults. Could Quick settings > Change have the same nice new structure that Menu > More has? Or even a search field.
