Tap/press the bezel near the front facing camera/upper left corner.
Would like to know how many are affected by this.
Hey guys just wanted to give a update on my phone. I reset my phone a few times but still had the same issue. Then I tried using the Nokia recover tool to do a reset but the problem was still there. About 2 weeks ago the problem got worse. If I touched d back top left part of the phone it started giving me the same issues just like touching the top left part of the front bezel. I wanted to try one last thing before sending the phone in for repairs. This time I reset the phone but instead of restoring to one of my old saved profiles I chose to restart a fresh one. Since all my downloaded apps & games were saved in the marketplace under my apps I figured I can reinstall them again with no problems. This time after I reset the phone there were no issues with the screen. I started downloading every game from before & played each one for over a hour to see if it might be related to a certain game and so far no issues. The previous times when I reset the phone the screen issues would reappear right away. So for you guys having issues with the top left bezel do what I did. Reset the phone but start with a fresh profile instead of restoring to one of your old ones & see what happens. If the issue comes back I will update this post but so far so its been great.
