I'm trying to figure out why my phone calls are having problems. I suppose it could be related to various apps I have downloaded. But I dread having to decide which should stay and which to uninstall. So now I am looking at my screen protector which has been on my phone for approximately 2 months. It is beginning to lift a tiny bit around the edges, specifically near the sensors in the upper right corner of the screen. Could the fact that the screen protector has lifted and might bend/move when I put my phone to my face make my calls have problems? It is lifting more around the speaker at the top of the screen. Is it time to change the screen protector?
