Lock Screen while talking on the phone?

Why would you want to lock the screen while you are talking to someone? The screen automatically turns off when you put it up to your face

It will still lock if you have headphones in, which I think is really the only time you need to lock it during a phone conversation

Until 1.1.3, if you where talking to someone all you had to do was tap the button on the top and the screen would lock.

Now with this update, instead of locking the screen it now disconnects the call.

This seems to be a problem unique to you. I can lock the screen by tapping the button on the top and it does not disconnect the call.

I suggest doing a Restore to fix your 1.1.3 update.

Its not just him. I was talking to my gf last night (and a few others calls this weekend), and when I click that button, boom, disconnected call.
I do it because quite frankly, sometimes when im talking with it to my ear, i move around, and the phone wakes up, and ill bump the big END CALL button.
It was so nice to be able to lock it, that way I know I wont disconnect anyone.
I think this is a HORRIBLE change, like the OP said.

this is a real problem for me too, since the upgrade I've realized my working pattern is to cal via the headphones, hit the lock button and drop the phone into my pocket. Since I've upgraded I have hung up on countless people through this unconscious action, and when I finally trained myself to avoid the top button either mute or end gets hit accidentally in my pocket.
Can someone confirm that indeed a 1.13 does work with the lock while in headphone mode? A restore would probably be worth the hassle for this maddening action.

I have 1.1.3. I just tried 3 calls, one on plug-in headphones, one using a bluetooth, and one with speakerphone. Immediately after the call answered I pressed the SLEEP switch. I pressed it several times. It DID NOT disconnect my call. So whatever is causing this behavior it is not simply the way 1.1.3 works.

I'm also able to lock the screen during calls using the Sleep button under 1.1.3.

Wow. Were you having other problems too, or was it only because of this issue? I tried a soft reset, and then going back to default settings, but it still acts as a hang-up button. I guess I will call Apple now.

Sadly, this is already a replacement phone, my last one kept losing contact with the SIM card and displaying a "no sim detected" error.

Thanks for all the help everyone.

I was on my phone today and why taking the screen goes blank, do it suppose to do that? When the call was over i tap the screen, it would do nothing. So then i press the button at the bottom and it would not even come back on. I had to press the top button to get the screen back on... Just got the phone is this normal????

All these problems are indicative to the 1.1.3 update.

That's a pretty amazing statement. I've had 1.1.3 since the day it was released, and I have NONE of those problems. In fact I have no problems at all, with any function of the iPhone.

It's possible that the release did not install properly; the fix is to re-install the update.

If you put the phone to your ear there is a sensor that turns off the screen so you don't accidentally select something with your ear. If you keep that sensor covered with your had or some other object the screen will stay blank.
