Screen goes black during call

[farukavdiu]

Hi there,
first i upgrade to 3.0 from 2.2
problem is that when someone calls me for 3 or 4 seconds i can see who is calling me and the screen is always on during these 4 seconds,but after that the screen goes black and i can still hear the ringing and to answer i must touch home button and then to slide for answer.
any idea....
thx

i dont use any cases and the sensors are not covered
