If you have a BlackBerry with a trackball that is getting stuck, it is usually due to a build up of dust.
· For a quick and simple fix, turn your BlackBerry face down and vigorously rub over an A4 sheet of paper.
If this does not work, try the following:
· Use a screwdriver to remove the ring from the outside of the trackball.
· Take out the trackball unit.
· Run your finger along the trackball to remove any dust or residue.
· Remove each of the four black wheels on each corner of the unit one by one. Again, remove any dust with your fingertips.
· Wipe the copper sensor (where the trackball used to be) very gently with a dry cloth.
· Finally, drop the trackball back and put the ring back on, with the prongs facing left, right and down.
