Thats a fallacious conclusion: Apple removed the End Call button from the lock screen, a feature that worked perfectly well as long as I can remember - at least as far back as my iPhone 3. Again, popping in to defend Apple's decision is not helpful. I'm here trying to figure out a problem I'm having, not get into an argument over how infallible Apple is or isn't. Unless you, like Chris, have some helpful questions or an idea as to why this is specific to my (and one other user's) phone then please, resist the urge to respond.
Chris, thanks for your response. The phone doesn't need to lock when you put it to your ear because the proximity sensor turns off the screen saving power. I'm a high-volume user though so I usually use headphones, and when you do the screen locks at the preset time in the settings, in my case 1 minute.
Before you say it, I know you can normally hang up the phone using the remote controls on the headphones, but these are really old and that button doesn't work so well any more. Otherwise they are perfectly good headphones with great audio quality and a great mic. Plus that remote isn't so easy to find in the dark. Oh well, I guess I'll have to start shopping for a new set of headphones.
If anyone from Apple is out there...please re-add the end call button or let me use the power button to end calls from the lock screen.
