This will bring Android apps to parity with iOS, which offers seamless app restores, letting users switch phones without making them feel like they switched phones.
One of the most annoying parts about moving to a new Android flagship is the data restoration process. When you transfer your data to a new Android phone, you carry over apps and some app data, but not all of it. Apps drop out your login credentials, essentially resetting themselves and forcing you to log into practically every app all over again to start receiving notifications. This is one of the reasons why iOS feels seamless: you can switch phones without ever feeling like you switched phones. Google is now working on reducing this friction with the new Restore Credentials feature, which will keep you logged in to apps when you switch devices.
