I have a problem: my phone doesn't see my pluged in earbuds, but if I play with bluetooth earbuds, you can't hear the game on the video. And I don't know how to do something that allow the phone to record the call (because of Co-op), because only one app can use the micro at the same time. So is it a problem if the video is muted or only have music in it?

I read in the rules that any modifications of shape and form are forbidden. Does it count as a modification?
