Phone Locking while on Calls - iOS6
I've noticed a change in user experience when on active phone calls after upgrading to iOS6.
After my default 4 minute lock period, my iPhone is locking the screen while on a phone call. Thus, if a need arises to take any action, i.e. open another application or hang up, I must swipe to unlock and enter my 4 digit key.
Is there any way to maintain the default 4 minute lock setting while preventing a lock when on a phone call? I cannot seem to find anyone with similar experiences running iOS6 anecdotally.
Thanks!
iPhone 4S, iOS 6
