Trackball 8800 Blackberry


Your trackball needs to be cleaned. You have two options.

1) You can send it in to be repaired, or
2) You can clean the trackball yourself.

To clean the trackball yourself:

The silver ring which covers the trackball can easily be removed if you use a small screwdriver to lift it at the outer side of the ring. Be careful here! (Like you should be during the whole process as all parts have very small plastic nipple which can break very easy.)

When the silver plastic ring is removed you will see the inner trackball component which can be removed completely. Before doing this you should carefully remove the silver metal ring that holds the trackball component in its position.

The trackball component itself can also be carved. For every direction the ball can roll to you’ll find a sensor wheel. Those wheels are mostly carrying some gunk you should clean them from.

Once this is done put everything back together to the place each pieces came from and secure the trackball with the silver plastic ring that you removed in the first step.

Your BlackBerry’s trackball should be back working now.

Track ball requires multiple press to get it to do anything


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

The ball won't scroll down


Have you removed the ball at any time? If it is put back in wrong, it could cause this. If not, the ball assembly itself might be bad. You can find them fairly cheap on eBay.

The tracking ball rotates but it does not move over the icons on the left side. Is there anything I can do to fix this?


Depending on how comfortable you are with removing the trackball it's not hard to fix... you may have some dirt or grit interfering with the trackball and/or sensors. Take a small screwdriver or blade and gently pop the silver ring around the trackball off. This will free the actual trackball housing. Use an old toothbrush to clean everything. I also soaked the trackball in a little rubbing alcohol. Just make sure it is completely dry before reassembling. If that doesn't work you can purchase replacement trackballs from places like crackberry.com.

Pop the ring around the track ball out with a small blade or your finger nail. Three double prongs hold it in place (bottom and both sides, none on top). Turn device over and gently tap the back. Track ball will release once ring is removed. At this point you can view the track ball and see exactely what is causing the block. Clean if needed with q-tip or remove lint/debris/etc... Just did this with my 8830. Working perfectly now. - {would not scroll down at all prior to}

Model 64213 (not a wireless model) Trackball is not working smoothly - already tried cleaning it and still gets "stuck" especially moving left and right. Up and down works well.


This is because the wheels that move with he trackball are getting stuck.

Try cleaning the inside housing.(The part that holds that trackball) Mainly, the tiny wheels that grab the trackball. Normal use can build up a gummy buildup inside that can be easily rubbed off with a cloth. Since the housing is underneath the trackball, there can be a greater potential for lint, crumbs or anything else to get inside as well. Clen in there, empty out any debree and you will find ti moves much smoother.

alternatively, one of the tiny wheels could be damaged and is not rolling properly. Roll each one with your finger to see if you can feal anything rough or if the wheel is rubbing against something.

Your track ball may simply be dirty. Get a q-tip wet with rubbing alcohol and rub your track ball and repeat until the q-tip stays clean. Hope this helps!
