My Iphone has developed a weird issues the last week. The home button isn't easy to depress anymore. The easiest way to describe what it feels like when pressing it, is that it is sticking somehow when pressed. I figured it would get better with time and more presses, but it is staying the same. Is it worth taking it in? I don't have apple care, but its still under warranty obviously. I'm curious if they would replace it or it would be a waste of my time. I'm not at all happy though. Unfortunately a lot of the phone experience relies on pressing that button. Any advice appreciated!
