Hello. A short couple of weeks ago, the left-most side of the touchscreen interface of the phone was nothing but dead spots. With the screen slid over the keyboard while typing a message, I could not hit the shift key or the 'a' key and get an effect. A little later on, the "Previous Page" functionality has just died. No matter what I do, I can't get that button to work anymore. Today, I felt like my phone was becoming slow and sluggish because I hadn't deleted my text messages for a while. After I did that, the "Return Home" functionality died, too. So now I have a phone I can't navigate with, because I can't return to the previous page or return home. Also, there are dead spots on the screen's leftmost edge. What can I do about this? Is the phone just falling apart?
