Dell Venue 7 Clock/Web Browser Issues

So my new (1 month old) Venue 7's clock keeps messing up - it will just start running fast, sometimes up to 45 minutes fast.  I've tried different settings, called technical support the other night (and they had me do the power + volume down button) and even did a factory reset on it.  The other issue is with webrowser, the screen will flicker and just stay white.  It might do that 1-3 times after you "refresh" the webpage.

Are these known issues or do I have a defective device?
