The precision of the touch screen has degraded to the point where I have to tap far away from letters to type them. There is a tool called Pen under Settings for this, but it doesn't work. It asks me to click on the screen, then on dots that appear in three places on the screen, ad nauseum - it goes through these points forever and never gets anywhere. After tapping these points for perhaps 20 cycles, I turn the phone off. Does this phone need a reboot or reset or something?
