I’ve used non-Google devices most of the time, now trying out an iPhone.
Just did a factory reset and restore via iCloud. My fear of loosing my phone, incomplete backups and messed up restore is gone. Works.
Might be possible with Google phones, too. For all the others it’s just messy.
(I‘d agree with you, until I tried it three weeks ago. Working with computers all day, I need others to take care of my personal and pocket computers...)
