Hi, I am loving my prime, however I have had a few instances of part of my screen being none responsive. This has happen in the mail app, stock browser and opera browser. The problem is that the top third of the screen becomes unresponsive so that I can't open settings, favorites or type a url in the browser. In the mail app I cannot delete selected e-mails. I changed the orientation to portrait and all worked but when I did a 180 I could use the top of the screen but then the home back and recent apps soft keys did not work. ie bottom of the screen froze. I put the screen ito standby turned on again and all appeared ok. Has anyone esle had this issue?
