Hello, I need a few tips on how to prevent the touch screen from getting all glitchy again. I do runs regularly and I use my phone as a music player. Problem is that I can't put it in my hand or in my pocket, otherwise it gets slightly moist and completely unusable while running. Will a simple screen protector prevent getting humidity on the phone or anything else? Or will I need to get something else that will be used as a music player? Thanks in advance!
