Spontaneous repetitive automatic pausing issue.

I decided to download that newest MCPE beta, right? So, get this, after signing into xbox live and all that stuff, I get ingame , only to find that this version keeps pausing itself! I look around, five seconds later, pause. I move around, still pause. I just leave it be, STILL PAUSES!
On the pause menu, there is also some font garbage on the upper left corner. Not sure if it's relevant.
