i just got a new lumia 820 2 weeks back. The second one i.e. The first had display issues. after a couple of days the second phone developed problems with the camera. when the app is activated i get a blank screen. im not able to access any of the options for the camera. No pictures .. Videos. Zilch. Any one else with camera problems? I get the feeling the whole lot from which i got my set is bad. Its gone for repair. And worse supposedly replacement is not an option as per the care centre.
