Google/Apple management could make this happen. All they have to do is have a big bin of phones outside the weekly team all-hands meeting. Everyone must throw their phone in before the meeting. At the end, everyone takes a random phone, resets it, and logs in.
While engineers refuse to do that, the process is still too cumbersome.
Best suggestion I've heard all week. Maybe it would finally realize my desire to cleanly keep a constantly-synced "hot standby" phone ready for deployment in case my primary one is lost. (Even better both would "just work" so I could grab either one on any day).
