When I go to "Settings - Backup & reset", right under the "Restore data" entry in "Xperia Backup & restore" section it says: "Last backup: 101 days ago". This is already strange, since my phone is set up to backup itself weekly.
But if I actually hit the "Restore data" entry, it will show me my backup file named "This Xperia XZ" and dated "July 1, 2017". This looks correct, since as I said above, my phone is set up to backup itself weekly.
But what could possibly be the reason for that discrepancy? July 1, 2017 was only 7 days ago, not 101 days ago. How does that "July 1, 2017" timestamp on the backup file agree with that "Last backup: 101 days ago" comment under "Restore data" entry? Do I somehow misunderstand the meaning of that "Last backup" comment? And if so, then what exactly does it mean by those "101 days"?
