Your phone's screen has some dead pixels. You're not too excited about the prospect of shelling out for a new phone. What's the fix? Massage them away! Intrepid Make magazine contributor Tim Watson was quite distraught when his iPhone screen took a turn for the worse, following an accidental dousing in beer. He dried it immediately and all seemed well, but the next morning revealed a band of dead. After scouring the internet and finding others fixing their LCDs with a spot massage, he gave his phone a specialised rub-down.
I used a Sharpie marker and started slowly pushing on the screen. I pushed with enough force that the screen noticeably discolored under the cap, but not enough pressure that I was scared of breaking the screen. And slowly, 1 pixel at a time, the grey dead blob started moving up and toward the top of the screen. The blob left other dead pixels in its wake, but they were red in colour instead of grey, and tended to fade and disappear within a couple of days. It took a couple of weeks of working on this process to get the grey blob out of the way, but I have finally succeeded!
While having a small cluster of dead pixels in your phone's screen corner is less than ideal, it certainly beats having a giant bar of them across the middle of the screen. For the cost of phone replacement, it's probably worth giving your screen a light Shiatsu to possibly resuscitate it.
