Issue with Proximity Sensor during calls

I too experienced the problem 3 days after getting my 4. I also had the ring tone continuing after my call was answered, and my voice mail message continuing to play when I called back the person leaving the message. I returned the phone for a new one and 3 days later, this one is fine. I was wondering if using the speaker (even though the quality is not as desirable) when talking would avoid the issue until there is a repair??

I'm having the same issues with my phone as well. I thought I was the only one. Great I stumbled on this thread. Almost every single call I've mad, the "hold" feature has come on in the middle. Such an inconvenience. I've tried restoring my phone, hard resets, powering on and off, etc.. nothing works. Def an issue that needs to be addressed.

This issue is very frustrating. I have the exact same problem and did not have once this issue with either my 3GS or my 3G. I am going to open a case with support to see if I can exchange my phone.

I am having the same problem. The face has ended the call, put me on hold, mute, and may other key functions. The only fix I have found is pressing the phone into my face at all times with constant pressure.

I've just had my iPhone 4 replaced at the Apple Store (West 14th Street, NYC). I'm waiting for it to restore before I can test the new phone's proximity sensor, but I learned a few things today that I thought I'd share:

Apple is aware of the proximity sensor issues. Josh, my Apple Store Genius, says he is hearing about them regularly, replacing phones and doing captures for diagnostic purposes. He also says several Apple Store employees have had/do have the issue with their proximity sensors. Josh claims these issues will “hopefully” be fixed by the forthcoming firmware update Apple hinted at in its PR release today.

The overall feeling from the appointment was that Apple is aware of the two biggest issues (metal band signal loss and proximity issues) and the Geniuses have been told to point to the Apple PR letter and say that a fix is “coming soon.” Which is fine, I guess, since they’re replacing phones with the proximity issue.

My new iPhone is syncing right now, so I have yet to test if it solves my issues, but here’s hoping.

I had my iPhone replaced last Saturday due to this issue (after a horrible experience at the Genius bar) and a week later I'm still hanging up on people. Extremely embarrassing to have someone call to ask how the phone is and then hang up on them twice.

I'm in the queue to get a call-back from a phone support rep, but unless this is fixed soon I'm going to have no choice but to return the phone. i use it for business, and hanging up on clients is not acceptable behavior from what's supposed to be the best "phone" out there.

Shame on Apple for this poorly-tested release, and their pompous response to issues so far. I hope the Android phones are decent.

Wow, I am hoping for a solution soon! i purchased 11 new iPhone for my employees and I. 6 of us have had the issue with calls being muted or speaker-phone activating whilst on a call. It is really annoying. Even more so for me since I have to listen to everyone complaining about it alllllll the time!

I am having BIG problems with the proximity sensor! Every single phone call I've made has hung up, muted, put on speaker, merged to another call after answering call waiting, and/or had buttons pushing in their ear. Everyone I speak to seems to be very annoyed to where I wont even talk on this phone anymore. It needs to be fixed right away!

didn't work for me
i'm about to go crazy with this issue
i can't believe i'm saying this, but i'm getting closer and closer to returning the phone

I have this problem with my new iPhone 4 and a new replacement iPhone 4.

I've had the new phone for a week and have had this happen on numerous occasions (Mute, Hold, Transfer, etc.) I just wish it would be acknowledged by Apple and to let us consumers know what to do. Either to return the phone due to a hardware issue or wait for a fix via a software update. Giving it until Sunday and making an appointment to return the phone, as I've had enough embarrassment talking with clients and hanging up on them.

I was having the same issue. Did a RESTORE and SET UP AS NEW IPHONE last night and haven't had a problem since. Seems to be a bug when first setting up the phone and restoring from a 3gs. Like I said i haven't had any problems since. Hope this helps!!! Cheers

It's not just a bug restoring from a backup - my wife's phone was set up as a new phone (not as a restore from a 3G backup) and her phone has the issue.

I have this problem too, hope apple will fix it somehow.

Add me to the list as well. I'm on my 2nd iPhone 4 (first was replaced due to ear speaker failure) and now I am having problems with the Proximity Sensor. Hopefully this is just a software issue.
