Ok so my power button started to sink into the phone where it's almost flush with the top of the phone. because of this, I downloaded an app called "no lock" which allows me to turn my phone on with the lower volume button. Am I just gonna wear out that button and have the same problem with two of my buttons instead of just the power button? I know the power button sinking has been a somewhat common problem. I guess what I'm asking is has anyone had problems with their volume buttons sinking, breaking, etc? Or are those buttons tougher than the wimpy "power" button (there's an oxy moron)? Thanks for any info in advance!
