Right out of nowhere about 3/16" to 1/4" of the right side of my touch screen doesn't work. There's this non responding strip running down the right side of the screen. Doesn't look any different. I didn't drop the phone or expose it to water or anything before this happened. I'm rooted and running mikfroyo v4.61 and have been for months. I also noticed that at least one app that I don't use regularly has disappeared. I've popped out the battery and left it off for a few minutes, I've peeled back the screen protector. I'm not quite sure how to proceed but I want to try everything before I unroot and bring it to sprint. I'm not under warranty anyway. I've had a similar (not such a specific location on the screen) but more temporary situation, very occasionally, when the phone is charging. This didn't go away when I disconnected from the charger. Looking forward to any and all suggestions and ideas. Thanks.
