I had my DroidX Cell Phone since when it was released last week.
The Cell Phone was working very well with no dead pixels on any of the menu screens, none on any of the software applications, and none on the Camera or Camcorder applications.
I had checked for the dead pixels using different colored backgrounds, and using dark screens especially with the Camera and the Camcorder application.
On Tuesday afternoon I downloaded and installed the DroidX 1.13.604 Update.
The DroidX now has some dead pixels in the same location only in the Camera and Camcorder applications, and not in any of the other applications or menu items.
You need to use the Camera and Camcorder applications in very low light and viewing a dark screen and you will definitely see the white colored dead pixels.
If you using the Camera and Camcorder applications and you are looking at an object in a bright light or in an outdoors setting you will probably not notice the white colored dead pixels.
Since the dead pixels only occur in the Camera and Camcorder applications it is probably a software related bug.
