Issue with Proximity Sensor during calls

Just wanted to chime in to say that I'm having the proximity sensor issue. I've hung up on 4 calls so far today.

Count me in as another experiencing this problem. Over two years of use with a 1st gen and a 3GS and never experienced this once. Happens at least once on most phone calls. Ugh!!

I am also having this problem. It's incredibly annoying. I've hung up on almost everybody I've called accidentally because of this. Speakerphone comes on every once in awhile. One, that doesn't make sense, is sometimes I'll somehow close the phone app with my face. I know I'm not pushing the home button, but I'll see the screen light up and I'll look and it's on springboard with the green bar to touch to re-open phone app. Really REALLY hope this is fixable with software and not a hardware defect.

Same exact problem here. Already cost me money by creating an international conference call on me while I was on a different call. How on earth is this possible?

My ear puts my calls on mute from time to time on my 3G so it's not a new problem.

Same problem. I never wanted to start a face chat use my face! hung up on someone like 7 times, muted, speakerphoned. it's not good.

Add me to the list for what it's worth.

My wife is having the same problem and is seriously considering returning it.

My wife tried my phone and did not have the problem so maybe it's certain phones?

Not adding much help to this thread, but I'm having the same issue and it's really bad. During calls, the phone will flicker on and off nearly every second. I've muted calls, hung up etc with my ear on nearly every call I've made.

I'm worried this is a hardware only fix. Hopefully a firmware update can increase(?) the sensitivity of the sensor?

Never had this problem with my 3G phone in 2 years.

The proximity sensor on the new iPhone 4 has been changed somehow and the sensitivity is not set properly. I purchased three phones yesterday and all three act the same. The display activates at less then 1 inch from your head and is slow to deactivate. I have facetimed, muted, and kepressed all at least 12 times in the first day. Twice just while leaving the Apple store. While using the phone in a dark room, I noticed by simply rocking the phone left or right less then 1 inch the display would activate. Having purchased every version of iPhone on each launch date, I have never encountered this problem. Hopefully a firmware update will fix this!!!!!

I am having this issue! I've had the phone for two days and have already dropped about 15 calls. My face keeps ending my calls, pressing numbers, muting calls and putting it on speaker. Apple needs to get this PROBLEM fixed right away. It's a super inconvenience to have to hold to phone away from your face OR pushed up against your face. It's like they didn't even test the phone out or they would have figured this out within the first 5 mins.

I experienced this issue yesterday as well and found that by readjusting the phone on my ear things worked out better. I think they moved the sensor to accommodate the camera. The previous phones all had the sensor exactly where the front facing camera now resides. I believe they relocated the sensor to directly above the speaker on top (which is why the white version) has those slits in the top over the earpiece. This is the same area that I covered last night which seemed to fix things. Although I would think my big @ss ears would have no problem covering the sensor no matter where it is in regards to the earpiece so I'm not sure this is the case or if it is a glitch/settings issue/etc. Is anyone able to actually see the sensors? I cannot seem to do so on this phone.

Good luck.

Same problem here. Speaker phone was just turned on by my cheek. Happens everytime I use it, something gets pushed or clicked by face. Never happened on 3g version.

Your holding it wrong!
