But I wanted to point out, Android is much, much more permissive in what peripherals and apps can do.
That's kinda true, but not what I was getting at. Android has restrictive background processing limits and the APIs around it keep getting more restrictive and the OEMs like Samsung keep ignoring the rules of how things should work and break your apps when you do it right anyway.. Ultimately it's incredibly difficult to write an app and guarantee background work.
Apple, is even worse on its restrictions of background work, but Apple owns the OS and and can bypass it all for their watch.
Apple will never get to bypass the fuckery you have to deal with on Android, only the Android OEMs get that.
