I've been searching for an answer to this, but have been unable to find anything. If I don't have any apps open, and the phone is either locked or unlocked, and I end a received call it opens my contacts. Is this the normal behavior? Is there a way to change this? I'd rather be taken back to the spring board. If I have an app open at the time I receive a call, I am taken back to the app after ending the call, which is great.
