If the trackball (that white Pearl like ball) in your BlackBerry is responding too fast, try to lower the sensitivity number.
To change the sensitivity of the trackball on the BlackBerry, follow these steps:
- On the Home screen, go to Options > Screen/Keyboard.
- In the Trackball section, click Horizontal Sensitivity or Vertical Sensitivity to change the sensitivity level.
- Press the Menu key and then select Save. The new sensitivity levels are saved.
Note: A higher sensitivity number indicates a higher sensitivity level for the trackball.
