A friend of mine recently purchased a Lumia 820 and found that during the call the screen turns black.
I found that this is a common problem.

I want to know what all manufacturing defects I need to check when I purchase a new Lumia phone so that I can get it replaced if there is any. This is because dealers usually give replacement if any manufacturing defect or issue is reported by the buyer within 48 hrs or purchase.
Do we have a list of such issues.
