At the moment I am thinking about getting a new phone in the foreseeable future. I was long time using android, but switched to iOS 5 years ago because of the longer update period. Now also some android devices offer a longer update support of about 5 years. Now I am thinking about switching back to android.
But i am wondering: is there any big difference from a privacy perspective between iOS and android? I know you can go for custom roms on android that are focused on privacy which i also used in the past, but i am not planning on doing this in the future. So it would come down to stock android vs stock iOS. Any advice there or is all lost anyway?
Some phones can have GrapheneOS.
I made the switch to Pixel last year and I can tell you that the ads on it are far more precise than on iPhone.
FDroid and Open Source are good.
