Ok so this is my first post on this forum so bare with me. I am having an issue with my new Galaxy S4 that I can not figure out how to fix. I have searched and came up with no results at all. My home screen keeps turning on when locked and there are not any notifications that are making this happen. It happens when charging and not charging. I looked in the settings and see that there is an option to keep the screen on when charging. This is not enabled so I can not figure out why the screen keeps illuminating for no apparent reason. Just to clarify, it is turning on to the unlock screen where you unlock to use your phone. Any help would be greatly appreciated.
