See if your phone works while using multitouch, for one point it's ok, but for 2 or more points it doesnt work, i tested it on 3 lumia 620 and all had this problem, for example, when zooming do it slowly and you will see the screenin "shaking", try a game that require 2 points, for example "rizing". Or just download this app multi touch test or hardware tests, and you can also see this video of one lumia 620 with this problem! http://www.youtube.com/watch?v=_8qL8uaTLac
All lumia 620 users, see if youhave this problem! thanks
The other problem is when you are listening to music with the volume under 10/30, you will notice that the volume goes up and down when you dont change it!
