We have over 100 9641g handsets that appear to have touchscreen problems.

The phones are on version 6.2313 of the firmware and they work fine after install. But overtime, the bottom of the screen becomes inoperable and all the buttons on the quick panel shift out of sync.

Tried the screen calibration but obviously, without the bottom of the screen for use, you can't complete the calibration. So far, all we've had to do is replace them.

Is this a firmware issue? Anyone else had a similar issue?
