Can someone please just post a video of your now working phone, with your thumb covering the left seem and monitor signal. Leave your thumb there for 1 minute.
It would be a quick video. Basically anyone with this problem can recreate it by taking a big fat thumb and placing it over the left seem for at least 1 minute, if you can't do that then there is something to this.
Not a faint touch either, just slap your thumb on the seam like you would if you were holding it lefty. 1 video as proof.
Well we need to see before and after since this doesnt affect all phones and/or all locations.
