General Smart stay and timeout quit working

view story

http://androidforums.com – This is literally happening everyday now. I have my phone set at 15 second timeout with smart stay on. It used to work awesome. Now the eye never pops up and the timeout doesn't work and the display just stays on unless I hit the power button. It works once I restart the phone but that's it. It shouldn't be like this. It doesn't even work if I switch smart stay off then back on. Is there a fix? (General)
