I got my Galaxy S4 a couple of weeks ago and it started doing this weird thing yesterday where it blacks out to the Date and Time screen for a few seconds then goes back to what ever I was doing. It doesn't matter what I'm doing, texting, internet, pandora, media player, it just locks me out for a few seconds and doesn't let me do anything then it randomly goes back to normal like nothing happened. It's getting really annoying. Here is a screenshot of it: Screenshot_2013-06-02-08-48-17.jpg
I have tried turning off all the gestures and every optional thing I can think of and I uninstalled all the recent apps that I had downloaded.
