Issue with Proximity Sensor during calls

Very annoying. Sensor seems be set at about 3/4 in.

I agree, I didn't expect them to have a fix yet, willing to wait, but was hoping they would have at least acknowledged the issue.

This is ABSOLUTELY happening to me as well. Facetime calls, speaker phone, hangups, etc...

I didn't realize that my cheek was so pointy.

I have the iPhone 4 and I was having issues with it today. After a reboot on my phone, I tested it against my wife's 3GS (She is waiting on White) and they were exactly the same distance and response time to return from 'sleep' from the sensor black out.

Could have been the reboot/.

On my third replacement phone due to this problem. showed the rep at the Apple store and they advised that I move the phone up on my ear. So far seems to help. But this needs to be fixed.

Some issue here. Never had issues before with 1st gen or 3G, but now the 4 will often call others on the contact list while in another call.

I am having the same problem and googled to see if anyone else was.......low and behold, here I am!! Very annoying. I am an XAJ (Xtreme Apple Junky) and the iPhone 4 is a let down between this problem and the antenna issue (http://discussions.apple.com/thread.jspa?threadID=2475407&tstart=0)

Same Problem. It happend 8 times in one call. It once muted the mic, put it on speaker and then tried to initiate FaceTime. THis needs to be fixed.

Having the same problems as everyone else. It's really annoying how a lot of buttons are being pressed by my cheek during a call..normally when I cover the top portion near the earpiece the screen should shut off but nothing happens when i do this. This needs to get fixed already!

I've had all 3 iPhones (1st Gen, 3G & 3GS) and never had an issue with my cheek inadvertently pressing buttons but now almost can't make it through a call, in the last 3 days I have: called a second person on three way, put call on mute at least 5 times, attempted facetime connection at least 3 times. Although it sounds like a minor problem if this is not fixed it makes the phone unusable for calls without a headset. MUCH bigger problem for me than the antenna problem that everyone is worked up about.

We have 2 32GB Blacks, and the problem only seems to happen on my wife's phone. AppleCare said to restore the phone and setup as new, but that didn't solve it. My phone works fine for her.

Seems to be sensitivity with the proximity sensor. The screen remains black, but the phone is still very active. She's tried to initiate FaceTime with almost everyone she calls. 🙂

It works.... but not properly. When I first noticed it after hanging up on someone I thought there might be an on/off choice in settings. Nope, just another bug that needs to be fixed. Let me see if I got this correct. 1: don't hold it a certain way or your signal strength will decrease. 2: don't press it against your face because the proximity sensor is not calibrated properly and you will mute,dial or end a call unexpectedly.

This is a follow up to two threads I posted on this subject over the weekend. I submitted a ticket, got a case number, and spoke to an Apple rep on Sunday morning. She first asked if I tried the reset (which I did - to no avail), and then instructed me to do a restore as a new device. I did, and it seemed to work. As an experiment, I also did another restore (from backup) - my original configuration - and to my surprise ... it still seems to work.

I have been making a conscious effort to firmly place the sensor against my ear (initially) and make sure that my face doesn't touch the display for at least a second, and so far, not a single face dial.

I've given up using my 3gs leather case though ... due to the repositioning of the proximity sensor, it still gives me a lot of trouble. I wrote the case manufacturer alerting them to the potential problem when they come out with their iPhone 4 version.

I have had all 3 models and never this problem. I got the iPhone 4 on Thursday and it was putting me on mute. I had the phone replaced and the new one now calls people at random and tries to engage people in facetime. I also have problems with dropped calls and it doesn't matter with which hand I hold the phone and I have a case on it. Also if you hold it wrong it can cause a delay, me and my wife on a conversion had a 5 second delay in our conversation. THIS PHONE IS SCREWED UP AND I HOPE IT CAN BE FIXED WITH AN UPDATE, BUT I HAVE MY DOUBTS AND I THINK THERE MIGHT BE AN ALL OUT RECALL.

So happy to hear it's not just me. I've hung up on several people as a result of the proximity sensor not working properly. I never had problems with this on my 3G, but the iPhone 4 isn't working the same. I knew something was up when I asked my wife "where are you that a dog is barking" only to discover my cheek had navigated to the alarm sounds and the barking dog was on my phone.

I then figured the work-around would be to lock the screen when I make/receive a call. That's when I discovered the new "feature" that if you're using the handset, the on/off button no longer locks the screen -- instead it terminates the call!

So they not only broke the proximity sensor, but they took out the only decent work-around, too!

And to rub salt into the wound, the Apple support rep I spoke to confirmed that this new "Feature" that the on/off button ends calls isn't even in the manual anywhere. Genius! Sheesh.....
