Okay so here's the deal. I was using a lumia 830 with partial denim and upgraded to a 1520 which has full denim. When I upgraded I used the backup from the 830 which clearly has another firmware and it caused a corruption in the O.S according to microsoft. I reset my 1520 and started fresh and All is well, even runs smoother especially in the lumia camera app which actually lagged. I don't know your situation but if its similar to mine I would suggest starting fresh. Even if its different you should try fresh. I'm satisfied with the result.

I hope Microsoft has a resolution for this.
Thanks again Eustis! :)
