Looking on the 'net, I found that there were several DroidX owners that had a glitch with the original DroidX displays (app 1%). These units had a problem where 2/3 to 3/4 of the screen was unreadable. This was about 2 years ago.
This past week, I had my DroidX fail in the same manner. The bottom 2/3 of the screen shows a pattern of white/black/gray bars. The touch-screen still works, you just can't see what you are touching. I've tried to pull the battery and done a factory reset but nothing seems to work (not easy with your display messed up). The original "fix" on the new units was to get a replacement. Since these phones are out of warranty, I doubt that will be the solution this time. I was just wondering if anyone else phone has had this problem.
