All of a sudden within the last few days, when my screen times out & I have to unlock it, my screen goes directly back to the home page rather then going back to the page/app I was on when it timed out. It also does this when I'm on the phone...if it times out while I'm talking & I unlock it, I have to go back to the phone & then end call rather then it going directly back to the call screen. Help?! Is this a setting issue? I've gone through the settings & can't find anything. It's driving me crazy!
