Losing first digit when phone is off


When I pickup the phone and the screen is off, I start dialing a number and the first key press is lost and only turns on the phone screen.

Example, if I pickup the phone with the screen off and just dial 555-333-1212 I end up with 55-333-1212. When I realize the first digit only woke the phone up, I have to go back and retype the whole number.

This is NOT the behavior of the DECT cordless models DP-720/722.

Not the end of the world but, it’s a constant annoyance. Is there a way to change this in the settings, if not, I guess I should submit a feature request/update to GS?
