The left side(volume button side)of my screen seems to be much less sensitive than the right. Such as browsing Safari in landscape and hitting the top to scroll all the up. I tend to have to hit the top of the browser a couple times to get it to go. If I flip the phone and do the same thing it works every time. Does anyone else have this issue? I live near an apple store and am thinking of trying to exchange my phone out but Im not sure they will go for it. I've reset the phone and all that jazz.
