My Lock Screen disappears (screen powers off and goes dark) after only 4 seconds....but I want it to stay on so I can see the time and the background. This is when I am not charging it, just when it's sitting on the desk. Once it goes dark I have to press the power button to see it again, but it again disappears after only a few seconds. Also, I do NOT have a lock password set. Yes I DO have the Screen Timeout set for 10 minutes (Settings > Display > Screen Timeout) and I do not have Power Saving mode enabled. Just in case I also set 'Settings > Power saving mode > Screen Timeout' to 10 min. as well. Oh and I also set 'Settings > Display > Touch key light duration' to Always on. Nothing has made a difference, this is driving me nuts. Any ideas?
