Hey guys. I have an issue with my RAZR HD screen lock. I put a screen pattern lock on my phone, but it doesn't lock half of the time. Even after the screen times out or I press the power button. When I turn on the screen it doesn't show the pattern screen all the time, it just shows an unlock button in the center that I have slide. Why isn't it showing protected pattern screen? How do I fix this? Any help would be greatly appreciated.
