touch screen stops responding during call
 

A NOKIA 5800 MUSIC EXP..., works very well but as soon as the phone rings for incoming calls the touch screen stops responding, yes you can only receive the call by call green key. even if you want to make a call, after entering the number and key the call button, the screen stops responding to an touch on the screen.
I mean during call the screen touch stops responding, only call, end call and menu keys continues working, but after the call starts working.

i kindly beg solution to this.

Flash ur device and also check the mic section.
