Every since the latest update to the OS, my phone has had extremely annoying problems with the touch screen. After unlocking, it'll work normally for a few minutes, but after that, it'll start registering holding down my finger as my rapidly tapping on the screen. If I lock and unlock the phone, it'll start functioning correctly for a bit and then start that nonsense again after another few minutes. I have no screen protector, I've tried rebooting, I've tried cleaning the screen, and it's not connected to the phone overheating because it can be hot and function normally or be cool and start failing. It really feels like the only change was that software update. =\
