Lg quantum calling screen issues


Lg quantum calling screen issues

My issue if with my LG quantum is when i make a phone call or recieve a phone call the touch screen will lock and go to sleep so i cannot end a phone call, enter any keys for an extension, cannot put on speaker phone and so on. I've had this issue for about 3 months now and since i've had the issue i've been looking for a solution.

I've restored to factory settings via the zune software

I've restored using the keys on the phone

Still haven't figured it out. so if anyone has had this issue and resolved it please let me know how.

Thank you
