anything to check/look at in Settings > Language and Input ??
set options to default ?
I had the same thing happen to me. I had to Hard reset the U9. None of the apps have worked correctly since.
It would be best to back up your data and do a factory reset. If that won't help, reflash the latest firmware.Only thing in there relating to pointer is the speed. Tried looking through all the input options but nothing relevant unfortunately.
