My HTC legend phone dialer is not working properly - cannot select numbers 1, 2 or 3 - if I touch these numbers on the pad I get nothing or the numbers below, 4, 5 and 6 respectively.

The touchscreen has no issues in any other application - calculator, messages - number and alpha keys pads fully functional in these other applications.

I have tried to download an alternative phone dialer app but these all seem to use the HTC app in the background as the exact same problem reoccurs in these apps on this phone.

I have also tried to download a couple of voice activated dialers as a work around but so far not successfully, one was pretty crappy to use and the other required 6gb of free SD card space which I don't currently have.

Anyway of reinstalling the htc phone dialer software without wiping all my info on the phone?

Any other ideas?

All suggestions happily accepted!
