landscape mode disabled when on call

[bigrckstr]

Hows it goin everyone, I was wondering if i could get some help please?

I noticed that when im on a call I can't rotate my phone to landscape mode. I just recently installed the finger key board 2.0 and it works great but when Im on a call, i can't rotate the phone. I tried deleting the program and checking all my settings but can't figure it out. Can i get you opinion? thanks.
