How to deal with iPhone 4 proximity sensor problem ?

[laura331]

I got an iPhone 4, had that problem with the proximity sensor, I heard that this is a widespread problem with iPhone 4. Should I return my phone back to the store, or is it something with all iPhone 4s.

Thanks

believe it or not i work retail and see this ALL the time.... make sure you take off the front plastic that came with the phone and make sure you get the right screen protector cuz if not you are blocking the sensor itself not allowing it to function properly . i know it seems obvious but i cant tell you the number of times it has happened

If after removing the plastic protector you still have that issue, then take it back to the store.
