I'm not sure what happened, but today my lock button randomly stopped working properly. To put lock my phone I have to press down on the button incredibly hard. I Googled it and was lead to an entry on here where someone had the same problem. They were directed to take it to an Apple store, but that's not an option for me, as the nearest Apple store is 3 hours away. Is there any way to fix this myself? There aren't even places like Best Buy in my area.
