Last week the genius bar at the local apple store was nice enough to swap my defective 5S out for a "new" phone (says new on the receipt, came in a plain box with some kind of sticker on it, I'm still skeptical) All was well, until I noticed that the power button was not an even height. To make it simple, the left side of the button is near flush with the phone while the right side seems normal. Now I know this may come off as OCD, but the button is harder to push when using my left hand, due to the flushness of the button and the case. I'm worried that the button will only get worse, and then have Apple blame me for it not working anymore, prompting me to shell out 79 bucks for a replacement. Is this enough of a reason to request another exchange? Does anybody else have this issue with their 5S, or even their 5? I know for sure that the defective 5S I exchanged didn't have this issue, but I don't want to waste time with the genius bar if this is considered "within spec." Is there usually an exchange period for swapped out phones, or would it even matter since I purchased AppleCare+ ? Thanks for your advise. This is my first venture into the iphone world, after a long sting on the Android side.
