The BlackBerry smartphone trackball fails to roll in a particular direction.


Debris is lodged in the trackball.


The trackball user interface found on certain BlackBerry smartphones is similar to the trackball used in a mouse in conjunction with a desktop computer.  In the event debris comes in contact with the trackball and affects the usability of the BlackBerry smartphone, rapidly roll the trackball up, down, left, or right to potentially correct the problem. If rapidly rolling the trackball does not correct the problem, please contact your wireless service provider for support options.
