The following information is intended for retail support representatives who are assisting customers with troubleshooting.

If the customer experiences any issues with the trackpad or trackball not scrolling, use the following as a basis for helping the customer.

Try to duplicate the customer’s issue

Validate the symptoms that the customer is experiencing. For example, practice using, moving, and navigating using the trackball or trackpad to duplicate the customer’s experience.

Check for customer error or insufficient customer knowledge

If the customer does not fully understand the how their BlackBerry smartphone works, provide them with the best usage practices. In this case, no further troubleshooting may be required. For example, educate the customer on best practices for protecting the trackball or trackpad, including the following:

  • Always use a holster or sleeve
  • Do not use the trackball or trackpad with wet hands

Clean the trackball

The trackball on a BlackBerry smartphone can get dirty from everyday use.

Note: Do not use water, compressed air, or any cleaners on the trackball. This damages the BlackBerry smartphone and voids the warranty.
Hint: Removing the battery as part of this process helps to avoid accidental key presses.

To clean the trackball, complete the following steps:

  1. Turn off the BlackBerry smartphone.
  2. Remove the battery from the BlackBerry smartphone.
  3. Press and roll the trackball up for 15 seconds.
  4. Press and roll the trackball down for 15 seconds.
  5. Press and roll the trackball left for 15 seconds.
  6. Press and roll the trackball right for 15 seconds.
  7. Confirm that the trackball feel improves. If the feel does not improve, repeat steps 3 to 6.
  8. Reinsert the battery and test trackball performance.

Test trackball or trackpad sensitivity

  2. In the Trackball Sensitivity or Trackpad Sensitivity menu, select Horizontal Sensitivity or Vertical Sensitivity to change the sensitivity level.
