I have a Thunderbolt and I'm having problems with my screen during calls. The screen will come on randomly while I'm on the phone and my face will trigger the mute button or speaker phone. This is REALLY annoying. I want to create a profile in Tasker that will turn my screen off while I'm on a call. It seems like it should be a fairly easy profile to create, but I just can't make it happen. Can anyone help shed some light on this subject for me? Thanks!
