This just started today. Whenever i wake my phone with the power button, i cannot unlock the phone. All of the physical buttons on the phone still work, but the touch screen doesnt respond to input. If i do a battery pull i can unlock the phone when it first starts up, but once it goes to sleep and i wake it again, i cannot unlock the phone. I had widget locker on and figured it was that, so i turned it off; the stock lock screen does the same. Had Monster Rom 1.1 running flawlwssly for the past couple months and figured something might be conflicting, so i changed roms to Liberty; lock screen still not functioning correctly. Any ideas?
