I just had to do my first hard reset on mini4

So I'm playing with the slider over function while having safari open. I then open up my podcast app from the slide over menu and start playing a podcast. I go to slide the window back over and everything ceases up. I couldn't make it do anything. The podcast kept playing but the screen was completely unresponsive. I ended up holding the home and lock screen buttons down and that did the trick. Anyone else have this happen yet? I'm hoping this was a one time deal. I've only played on it for about 2 hours.
