My track ball will move around normally in any direction except up. Its hard to move it up, I have to swipe several times for it to move up. Any thoughts?

You should remove it and clean it. There is a thread on it if you search. Be careful as it does void your warranty if you break it.

While pressing the track ball in, move it in the direction that it wont scroll. Do this a few times.

Yeah I dropped my phone once when pulling it out of my holster...I caught it but it hit the holster as I grabbed it and messed up my trackball...made it do the same thing...

I managed to fix it by doing what Garz said but eventually I ended up having the trackball replaced anyway...

I did have it happen one time since then but it fixed itself after a minute or so
