dhn - a mystery...
Why does this almost ALWAYS (99% of the time) impact the upper right corner of the screen. I bet if we went back and counted, almost every report would be of a phantom touch to the upper right, causing the first menu + Help me + Walk to help + Nearest police station... a succession of right upper presses. Why would crud have a tendency to collect there and not along the BOTTOM of the screen where you'd more likely expect it?
Further to that, why do so many units seem to exhibit this problem more often when the bezel, made of some thermoplastic or another, begins to warp(?) with heat? Seems to me there's a fundamental design issue with the way the bezel is being held in at the top, aggravating any bit of fluff that might be caught under there. Strange, isn't it?
To the OP - the cleaning may well work. It does most of the time. That said, we have had a few folks who question what's happening with the bezel shape and retention mechanics on their units, too.
