SOLVED! This was happening on the better halves phone that we just picked up yesterday. I put our phones next to each other & started flipping through menu settings, comparing the two. I finally switched the settings menu to "list view" & found her phone has a "developers options" tab all the way down at the bottom (for whatever reason, my g4 doesn't have this tab). 3rd down the developer options list is "Stay awake, screen will never timeout while charging", which was checked. Unchecked & screen turns off now.
