Did your screen stop locking itself?

Recently my screen stopped automatically locking itself when the screen shut off, which would often lead to pocket dialing when the phone was in my pocket a button got pushed.

Here's how I fixed it:

You need a registry editor like PHM Registry Editor (I think I found that in this forum). Go to \HKCU\ControlPanel\Backlight\ and change the AutoDeviceLockEnable from 0 to 1 then soft reset the phone and you're done.
