I can confirm I had this happen as well. I recently had the replaced due to a separate issue (front-facing camera caused the phone to lockup) and have not had it happen on my current phone.
Only ever an issue for me when the phone isn't actually touching my ear.
As an aside, the iPhone 4 doesn't have proximity sensor (at least there aren't any in the iFixit teardown). I believe it uses the front-facing camera, so theoretically it can activate if you move the phone away from your face in a very bright environment, as I noticed.
But if you hold the phone against your ear (like most sane individuals) it isn't a problem.
It has a proximity sensor. Otherwise, that camera would have to be on all the time, which it isn't.
The sensor may be located at a different place with the different models, and software calibration may play a role, too.
However, at least the original iPhone has similar issues, at least if you have long hair and/or facial hair getting between sensor and skin. So the iPhone works well for jarheads, but not for hippies...

Ha, failing here, all members of the jarhead clan.

No, it doesn't have a proximity sensor, the WWDC keynote slide confirms this as there is no mention of a proximity sensor, and also no mention of one in the iFixIt teardown (which describes every other relevant component). There is also no hole, which would be visible in bright sunlight, on the front of the phone other than that for the camera.
The proximity sensor was only ever active when you were in a call and not using speakerphone. That would be the exact same use-case with the camera, surely?
Also, the camera wouldn't need to be capturing in a particularly high resolution, as it is mostly the colour intensity that it needs, more than likely using less battery power anyway. I dare say software tweaks will be able to fix it.

I have to disagree. Every report of the phone mentions the proximity sensor. They didn't have to mention it during the Keynote, because they mentioned it in 2007.
I could post more. Do you think that you would be the only one who would "know" that the phone has no proximity sensor? You think these guys are that clueless? Using the camera for this is a non starter.

All those articles you link to are based on the flawed and factually incorrect assumption that there is an actual proximity sensor as with previous iPhone models.
In the keynote Apple mentioned every sensor that already existed on previous iPhone models, are you saying they just happened to forget to mention the proximity sensor? Highly unlikely really.
I challenge you to find anything in this teardown http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/1 that resembles the proximity sensor (handy tip, there isn't one), or are you going to say that they left it out too because it was already in a previous iPhone.
I'm merely pointing out the fact that there is ZERO evidence to support the fact that the iPhone 4 has an ACTUAL proximity sensor. May be the use of the front-facing camera has some bearing on the "finger-swipping-across-the-camera" patent that Apple has, as that certainly would have to be able to detect the covering of the lens?
If you really don't believe me, which you evidently don't, how about you try for yourself and cover JUST THE LENS of the front facing camera when in a call, and that will prove it to you once and for all.
It would be so unlike journalists to either get the wrong end of the stick, or just regurgitate what they've read without proper fact checking....oh hang, not it wouldn't, especially given some of the stories from your above mentioned sources. At the end of the day though, in reality, they are probably just saying proximity sensor because that's the job which the front-facing camera is aiming to fulfill.

I don't see you providing any evidence. I don't have the phone yet, so I can't try your trick. But I don't remember Jobs mentioning the sensor last year, or the year before either. Doesn't mean there isn't one. The fact that ifixit didn't mention it means nothing either. They didn't say, "There's no proximity sensor anymore" either. They don't describe everything in the phone. If the sensor is near the camera, covering that with your finger could cause the same effect.
We need more evidence.
It just occurred to me; why don't you try to ask ifixit? They may respond. If they say so, you would have a first.

Time for a nice big slice of humble pie. After much searching I have managed to locate the Proximity sensor, it's just above the earpiece. A lot closer to the edge of the device, so could explain the problem. They just need to tweak the sensitivity.
I haven't had a problem since it's been in a case, probably because the lip of the case blocks out some extra light or something.
Jobs mentioned when the 3G was launched definitely, cos they put in three proximity sensors, instead of just one.
This workaround is working so well for me I just wanted to repost it with additions.

Once you start a call, hit the home button and pull something else up on the screen like a photo so that if the screen comes back on it doesn't have options like END CALL or FACE TIME on the screen to accidentally hit. The calculator may be another good choice as the only way to get it off the screen is to hit the home button.
Just wanted to add to this. >>As soon as you initiate a call you can double click the home button to bring up recent items and then just hit the photos or whatever you were using as a quick shortcut. It will take you right back to whatever the last photo you had up and you can go to your call.
You can also use the double click on the home button while you are on the call in the photo app to view recents and then toggle between the phone app and the photo app if you need to get back to the call screen.
We definitely shouldn't have to do this but for people that absolutely need their phone without headphones etc.. this was a great suggestion!
This is working for me so far at least as a work around.

Chalk me up as another person with the proximity sensor issue. Was talking to my mom on the phone in Target when the conversation ended and suddenly started dialing my mother-in-law.

Yes, the proximity sensor is more of a problem with my iPhone 4 than with my iPhone 3GS.
Funny things happen when it touches my face. False triggers sometimes. And, I agree that this will likely be fixed with a software update that will "filter out" these false triggers.

Restoring the OS and then setting up your system without using a backup did not fix the problem. I was doubtful as I can't imagine what in the backup files would interact with the proximity sensor, but I gave it a go anyway.
Thought I had the problem. Went to AT&T. They said that it was the old case I was using (from my 3g). So I took off the case and the problem totally disappeared. Makes no sense, but that's what happened. Now waiting for inCase to come out with new stuff.
I've had this happen a few times, too. Something that hasn't been an issue for since the original or 3G (I can't recall).
Had it happen to me three times last night on a half hour phone call. Never happened on my 3G, usually the screen would not turn on. While I'm not all up in arms about it, seems like something should be done to fix it.
On a side note my phone has what I'm calling life grip. When the phone shows around 2-3 bars, I short the little slit in the antennas and it goes to 5 bars. Lucky, I guess?
Does anyone who didn't migrate from a previous iphone have this issue? And is there anyone who has tried resetting the phone settings but didn't have it resolve the issue?

I am left-handed and had problem with dropped calls.
Bought a Body Glove iPhone 4 case today at the AT&T Store (yes, the AT&T Store) in the local mall.
Problem solved!
Good Luck to Everyone!

That's ok, we all make mistakes.

I guess I shouldn't have been so "jokey" in my comment about the location of the proximity sensor.I agree that the location could be less ideal than before and that it can be adequately remedied with SW.
