I got this phone back in September and since then have encountered an issue whereby the mouse/cursor thing slows right down when the speed is at 80.

Any ideas how to sort this? And I have rebooted it a couple of times and it’s made no difference, sadly!

Is it a Pearl 8100? I think they’re known for issues with the roller ball as it was the first one they produced with a roller. The clicker on my Pearl’s ball just died, incidentally.

No it’s the 9100, the ball doesn’t exist and has been replaced with a sensor one
