Ok, I'm certain that this has something to do with the software, rather than the hardware of the phone, because if I lock, then unlock my phone, it fixes it. Anyways, here's the deal. Sometimes, when I'm typing something (I'm pretty sure it happens other times, but this is the only time I can actually notice it) certain spots on the screen won't be as responsive. Like I'd be typing something, and I'd have to press the "K' button on the keyboard more than usual (in multiple spots until it responds), because it wouldn't respond right away. Locking then unlocking fixes it, but it's still getting somewhat annoying. My guess is that it possibly has something to do with either the rom I'm on, or the settings in setcpu. Any ideas on how to fix this?
