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?
