What do you mean "set up"? Like when I get a new phone, my previous apps just reinstall themselves. I might have to log back in, but that only takes a sec with a password manager.

Does it not work like that for you?

I've only gone from Nexus to Pixel to Pixel though (all Google phones) so maybe that's why?

Configure all the apps as they were before.

Is like a new phone besides contacts/mails/photos, the rest (besides the pre-installation) is like I never used the apps on the phone.

From having to login to having to re-configure everything.
