I have a Curve 8330 and for some reason the nav ball only works when you move it up or down.When you move it side to side the ball will roll,but it wont move to the next application,or if it does move,it will bounce between two icons and only those two.Can anyone help?
Try a battery pull with the phone on, wait 30 secs then reinstall the battery.
Thanks,I took the battery out for 3 minutes,put it back in and its still doing the same thing.
I tried to change the sensitivity setting to different settings,but that didnt work either.
Pop out the track ball and see if there is any dirt or dust under it. Pop it back in and see how it does.
2nd this.. be very careful not to break the ring...
Just get a Q-tip and some isoproyl alcohol and rub it on the bottom of the assembly.. then let it dry and put it back together.. If that doesn't work you can buy a new assembly nav ball assembly
I just took the nav ball out of my friends 8330 and put it in my phone after I cleaned under the ball,and it still doesent work.My friends 8330 is 3 weeks old so the nav ball should be in good condition.
For whatever reason, I have seen a lot of 8330 have track ball problems. You can get replacement track balls for the 8330 (and others) on Ebay for $5 (shipping included)
