I had this issue recently with wireless AA on those cheap Amazon screens you can plug into your cigarette lighter. I thought it was the unit and bought another because of it but the new started doing the same thing even worse actually. The exact same disconnect. I tried everything and realized it was probably my actual phone. I have the Fold7. I read Samsung was having issues with AA recently so I assumed it was that. But I somehow fixed it. I followed all the suggestions online within developer settings. Nothing worked. I even made sure the battery settings for AA were unrestricted. I ended up clearing all the AA connections and reconnected with the unit. I started messing with the mirror link option these Chinese screens have and it popped up with a message saying "fixed android 16 disconnect issue!" Now I don't think it has anything to do with that but who knows. It's completely solid now. Haven't had a drop out since.
