Phone & Apps

Move Google Authenticator or Microsoft Authenticator to a new phone before you erase the old one. Sync, QR export and cloud backup steps.

You unlock the phone to check the weather and twenty minutes later you are three apps deep in something else. A busy Home Screen does that: every icon is an invitation, and the one you came for is on page four. Keep one Home Screen page with the apps you use daily, send everything else

A factory reset is the one phone fix you cannot undo. Done right, it wipes a phone clean for a new owner or clears a stubborn fault. Done in a hurry, it takes chat histories, two-factor codes and unsynced photos with it. Back up and check the backup, transfer anything that does not back up

The quick fixes people reach for, deleting random photos or installing a cleaner app, cost more than they save. Find out what is actually full, then remove the things you can get

You go to film something that matters and the phone refuses. The storage bar is a strip of colors with no instructions, and the obvious fix, deleting photos, is the one that can cost you memories.
