If your BlackBerry Curve uses the popular trackball, it's not uncommon for the trackball to malfunction. The roller ball design makes it prone to collect dust and dirt from your hands. Because the trackball is essentially your Curve's mouse, it is used heavily for scrolling and selecting items. Fortunately, fixing issues you have with the mouse can usually be done on your own. It is possible that all it needs is a good cleaning. Even more drastic measures, like replacing the trackball, are relatively simple to accomplish.

Skill level:

Things you need

  • Canned air
  • Dry cloth
  • Small flathead screwdriver or tweezers
  • Replacement trackball

  1. 1

    Attempt to clean the trackball as a first resort. Use your cloth to wipe over the trackball's surface as you roll. Do this several times. You can also use canned air to get rid of any loose dust or dirt. Test the mouse again; if it still isn't functioning properly, move on to Step 2.

  2. 2

    Obtain a replacement trackball assembly for your Curve. These are available from many online retailers. Most wireless carriers do not sell BlackBerry parts.

  3. 3

    Place your screwdriver or tweezers in the small space between the metal ring that surrounds your trackball and the Curve's housing. Start at the top, nearest the screen, and gently pry all the way around the ring. It should loosen without much effort. Set the ring aside.

  4. 4

    Flip the Curve over and gently tap on the back cover. The trackball assembly will fall out.

  5. 5

    Use your canned air to remove any dust and debris that has accumulated in the trackball housing (where the trackball used to be).

  6. 6

    Position the new trackball into the housing. Line the four tabbed sides up so they are facing up, down, left and right.

  7. 7

    Replace the silver ring, or use the new ring if your trackball came with one. Be sure to position it with the un-tabbed section at the top. Press gently into place. You will feel the tabs click down.

  8. 8

    Test the trackball by rolling it in all directions as well as using the "Select" function. If it is still not working properly, visit your wireless carrier or contact BlackBerry for assistance.

Tips and warnings

  • If you have a later model Curve that uses the optical trackpad, you may attempt to clean it with a dry, soft cloth. Replacing this on your own is not recommended. Contact BlackBerry or your service provider for assistance.
