automatic flip to be optional on human vs human

Is this an app thing so that you can play a game handing your phone back and forth with another person?
I found that on my Android phone and the board doesn't flip after every move. You must have something else going on.
I have auto-rotate turned off on my phone. I'll bet that's the difference.

I have the same suggestion. The automatic flip is a pain when you are trying to practise a position.
