Question about AT&T Blackberry Curve 8300 Smartphone
Hi, to change the trackball or trackpad sensitivity of the BlackBerry smartphone, complete the following steps:
1) On the Home screen, go to Options > Screen/Keyboard.
2) In the Trackball or Trackpad section, click Horizontal Sensitivity or Vertical Sensitivity to change the sensitivity level.
3) Press the Menu key and select Save. The new sensitivity levels are saved.
A higher sensitivity number indicates a higher sensitivity level for the trackball or trackpad.
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.
Try to re-install the BlackBerry Device Software using the application loader tool, before you re-install the software please back up the BlackBerry smartphone data.I hope this information will be helpful to you
