    I got my iPhone 4 this morning.

    Everything looks and works great except for the proximity sensor.

    For some reason, the screen turns back on within 1/2 inch from face, which makes me press buttons during a call. I was on one call and pressed the speaker button twice and the 3 key before I realized something was wrong.

    I took my wife's 3gs, and the screen turned on 4-5 inches from my face.

    Wonder if it's a hardware or software thing. Any other's with the new phone have this problem?

    I think the same thing is happening to me. I initiated a Face Time call, hit speaker, and hung up on the person all in one call.

    Ok, so its not just "me" being funky and imagining a problem.

    This seems like something that would have been picked up in testing, but I guess they were busy drinking beer.

    I just got on here to see if anyone else had this problem. I was on a call on my new iPhone 4 earlier this evening and i kept hitting buttons on the keypad, even though the screen was turned off due to it being next to my face. My 3GS never did this.

    Count me in. I had turned on mute and was super confused why the person couldn't hear me...

    I was just checking out Apple's support discussions and found a thread about this. Someone said they talked to Apple support and they suggested:

    Settings --> General --> Reset --> Reset All Settings

    (CAUTION will clear your wifi setups)

    I went ahead and did it since i only have one wifi password so far anyway. i'll see how if it helps in the coming days.

    they moved it up on the phone so maybe it is now missing your heads and keeping the screen on

    Everything works great as long as I keep it glued to my head. Once I forget about it, what do you know, I am calling someone else. The only reason I noticed is I heard a damn ring tone.

    Seriously. Whats up with all the issues?

    This problem and the antennae problem (Which I have as well.) seem like things that should have been noticed a LONG time ago.

    I only noticed the antennae issue after watching the video and testing.

    I seem to be having the same issue. I haven't pressed any buttons yet, but I can see the screen turning on and off when I am on the phone.
