I have noticed in the last couple weeks that my X will start to lose some screen sensitivity and make it almost impossible to type on, whether in portrait or landscape mode. Yesterday I actually had the screen become completely unresponsive. The hardware buttons worked fine. I could bring up my last 8 opened apps, open up the settings bar, even hit home and it would let me check which home screen I wanted to go to. But the actual screen would not respond to anything. I held down the power button to chose to power down the phone for a reset, because for some reason I was expecting to be able to select shut down from an unresponsive screen, and couldn't select this for the said reason. I did a battery pull and was able to use it again. Has anyone had this happen to them? Any thoughts? Thanks everyone.
