Issue with Proximity Sensor during calls

I'm curious - has anyone experiencing this problem (who upgraded from a 3GS to an iPhone 4) tried doing the Restore (as New Device) - and are you still experiencing face dials?

There are several of us who reported success after doing this, but some have said they did the Restore and it didn't work (without specifying if they did the restore as a *new device*).

Thanks.

Same issue, except my cheek hits the speaker button.

I also have "death grip" and really slow 3g speed issues.

I simple message from Apple stating that they are working on the issue would give me some assurance. As much as I love this phone and it's features, if it can give me basic service, it will have to go back.

I did a restore after I set-up the phone as a new phone. It seemed to have worked, I told myself it did. But that glee was short lived when I realized I have just been overcompensating for this issue. I think the truest test remains that the 3gs has a quicker response in turning off and turning on. My question is why did this have to change for the 4th generation?

I completely agree about this being a bigger issue than the antenna! One out of every three calls hangs up inadvertently on the other caller and last night I accidentally dialed a business contact at 11:30pm while on the phone with another friend. That's unacceptable - it's not good for me to have a phone this unreliable.

As far as fixing it is concerned?

I've restored the phone. Twice.

It did NOTHING.

I think Apple just doesn't have enough repair phones to replace all the broken iPhone 4's out there. So they're telling their geniuses to reject all the common issues with the phone in fear that if they do start replacing all the ones with proximity sensor issues and antenna issues that it will give legitimacy to the claims that it's a severely flawed phone (which it obviously is!)

Address this problem already Apple - because right now all you're doing is giving cadence to every person who ever told me not to buy the first generation or any major revision of an apple product. Ignoring the problem and pretending it doesn't exist doesn't make it go away. Until apple addresses the issue I will tell everyone I know NOT to buy this iPhone.

Add me to the list of all the things wrong with iPhone. Great!

skls - I originally setup my iphone 4 from my 3gs backup and was having serious face dialing issues. Based on feedback of others in this thread, it didn't sound like it was worth the effort to do the "restore as new phone" option because of the limited chance of success. Well, I was frustrated enough today that I was willing to try anything. So, I did the factory restore option in itunes and set the phone up as a "new device" and the first call I made afterwards.....wait for it....at least 3 face dial button hits. :-/

So, add another to the list where the restore as new device did absolutely nothing.

Same problem here. I was thinking of going to the Genius Bar, but apparently it looks like all the phones are having this issue?? Very frustrating! This is worse than the antenna thing. I've called people, hung up on people, but it on mute, etc. Please fix this Apple!

Hi All,

I know many of you all have done a full restore. I also know that hasn't worked. However, after, have you also done the:

"Settings>General>Reset>Reset all settings"

I've checked other sites as well, and it seems like it's working for people. My theory is that the default install of iOS4 causes some sort of gremlin and the "Reset all settings" sort of wipe's it clean? The reason I say it, is, the resetting the settings has (so far) worked well for me. We'll see how it goes...

I do have a question, though - I bought my phone at an AT&T store. I have a Genius appointment Friday for the proximity issue - I haven't cancelled it yet, so I have 24 hours to replicate the issue - my question, though... Is Apple gonna give me the "run-around" b/c I didn't buy it from the Apple Store?

Same issues as everyone else. A little over 2 weeks and counting to fix Apple, or its back to the AT&T store with the 4 and re-activate the 3GS.

No.

Apple handles all returns/exchanges/warranty on iPhones. If you go to the AT&T store they will direct you to make a Genius Bar appointment to do a phone swap.

I have not had any issues whatsoever with my iP4. What I don't understand is why are you all hitting your phone with your cheeks? I never have the phone close to my cheeks just for the sheer fact that the oil from my face gets on the screen. I hold the phone at an angle slightly on my ear and away from my cheek.

I asked my wife if she was having these proximity sensor problems and she said "proximity what,what's that?" lol Once I explained to her what it was, she showed me how she held the phone and it was exactly the way I do. She told me she doesn't like to get make-up on the glass.

Moral of the story is, we don't hold the phone on or near our cheeks, always at an angle on our ear, but slightly away from our cheeks.

No problems here!

Our phones are incredible and love Apple's new iP4!!!!

Thanks, codewrangler...

No Apple will not give you the run around because you purchased it at a At&t store.

I haven't had this issue at all, so I don't think it's universal.

Follow-up report:
I am on vacation and make a case ID online, went to the Apple store in Las Vegas this evening. While waiting, the specialist girl told me she *has seen the proximity sensor issue. I get to the Genius bar (real nice guy) and (of course) he was surprised and "hadn't heard of the issue". I said "That what everyone on this thread is saying about you Geniuses are telling us!. *He ran a "diagnostic", which was little more than pluggin into a MacBook Pro, dialing a few numbers and he told me he could not replicate the issue but was going to replace my phone. I thanked him and left. Went into the mall to test and... BOOM. same problem, MAINLY when I stick it on my left shoulder and hold it against my face. Cheek dialing galore... I ran back and showed the Genius... He watched and said "light was sneaking through and activating the screen" "Hold it differently".
this is getting INSANE. I virtually can't make any calls the way I have my whole life, including iPhone 2G and 3G.
Oh, btw - the sensor is DIRECTLY above the front-facing camera. Stick your finger over it and see for yourself. So, if a firmware update can't change the sensitivity, we have a defective HW design that I'm begining to think there is no solution for.
Oy Vay.... I am done for the day.
