Is anyone having issues with the pattern unlock screen? I will randomly try to put my pattern into the phone and it will highlight the first button i touch and say wrong pattern, even though my finger made solid contact with the screen without lifting it while inputing the 4 dot pattern. Sometimes it will even do a rapid 4 wrong pattern inputs when sliding your finger across the 4 dots. As if the phone thought I was tapping each of the 4 dots in my pattern. Ive found that when it does this, you have to turn the screen off, and back on, then wait 10 seconds before trying to input pattern again for it to actually recognize the sliding motion.
