I've been reading all the questions and answers to what seems to be common problem--screen timeout on lock screen won't adjust to the settings available. I have an LG Transpyre, and don't use a pin, just swipe. I have clicked on every option from 2 minutes, to "Keep screen turned on". Goes black after about 10 seconds no matter what. It has always done this, but I am using it more and more and its getting very annoying. I can also relate to screen going black while on a call. I can usually get it to wake up by tapping twice near the top of the screen. Any suggestions?
