You are not repeating anything. You just presented a vital brand new information.
"That is an Android 'feature' that Google (or is it Samsung?) introduced fairly recently. On my device, Blackplayer gets the dubious benefit of this unwanted functionality after each reboot. It needs changing at an OS level."
Where in here did you talk about this feature being baked into and not being optional? I don't live by Android, or phones, or whatever technology you guys are so into. I'm an average user. That's why, I thought maybe it's a feature that can be disabled. And I asked the question whether you know how to disable it. Then came your condescending reply:
As I said, it's an OS 'feature', you would need to get it removed at an Android level (so by Google, Samsung, etc).
...which also says nothing about the feature not being optional.
Explain yourself better in the future, guy.
