Right when I go to YouTube or notes or photos or something you can turn on its side it won't let me turn it I can remember doing something in my settings but I can't remember what I went on setting but couldn't find it please help I need to get it back

Try this. When your on main screen double tap the menu button and it will bring up a little task bar of recently used apps. Locate the settings app in that bar but don't click it. Hold your finger Down on it as if you were moving or deleting an app on the main screen. A little minus sign should come up by the apps click the minus sign by the settings app. (Dont worry it won't delete it) then power off your device and power back up and it should work. Let me know how it goes :)
