Hello, I was wondering if anyone can help me out. I got a white iphone 4 and i put one the wrapsol screen protector. My proximity sensor does not work. When i make a call the screen light does not turn off. does anyone know if the screen protector is the reason for it? My gf has the black iphone 4 with the same wrapsol and her phone works fine. Please let me know if any of you guys have the same problem. thanks.
