Automatic Photo Upload does only work if the vault is unlocked, which means for many people that are not digital natives it is not clear that they have to do something in order to make Autmatic Photo Upload work correctly.
As automatic unlocking of vaults during charging will/can probably not be implemented (?) I would like to see an option in the settings menu for Automatic Photo Upload that will provide a notofication in Android System during charging of the smartphne that Automatic Photo Upload requires an authentification in order to unlock the vault to start Automatic Photo Upload.
By providing this little notification that can be activated by demand in the settings menu, it will be much more clearer for users what needs to be done to get the jobe done.
