I am unable to pull down the notification bar while on a call using my Bluetooth headset. When my finger gets near the top of the screen, it trips the proximity sensor and blanks the screen. I'm not sure if this is a design flaw or something that I can fix. There are MANY times that I want to use my phone while I am talking to someone and it seems stupid to me that I cannot interact with notifications while I'm on the phone. Anyone else experience this issue and/or have any suggestions? Thanks!
