    proximity sensor still does not work with 4.1. I am still having issues with it muting people, calling other people.

    How about you?

    Mine has improved, but it's still doesn't resolve the issue.

    It seems to work right now when I put my phone up to my ear. However, that's something I don't usually do since I hate cleaning off the smudges my face makes on the glass. When it's about 3cm from my ear it pops on and off. I know that's not a problem since I'm not touching the phone but as a comparison the iPhone 3G never had that issue. It would always stay off when that far away from my ear.

    you can just make an appt at apple and swap it out also

    if the screen doesn't go off when you put the phone to your ear, the sensor is no bueno

    I think this could just be explained by a different sensor than earlier iPhones that is also in a different place now than before.

    Most likely which is a shame because the previous versions were perfect. At least they fixed the ambient light sensor. It's back to working as well as it did in the original iPhone.

    This explains that the proximity sensor problem really is a hardware problem, NOT a software problem. How can we explain that some of us with Iphone 4 don't have a problem at all with it? mine is working as it should!

    It has to be a hardware problem, and there has to be a high failure rate on the new proximity sensors they use. Let's face it: a software update won't fix this problem for those of you who has it...

    I have had major problems with the proximity sensor since launch weekend. It was bad enough that I even had my first phone replaced by Apple with a new one. Replacement was a week 30 production phone, and the problem was the same as the old one.

    I was reluctant to upgrade to 4.1 since I didn't want to lose my jailbreak, but after some thinking, I really don't need the jailbreak. All it really does it badly decrease my battery life.

    I just upgraded to 4.1, and it seems to have GREATLY improved the proximity sensor problems. It is activating and turning the screen off all the way out to about an inch. As far as I am concerned, the issue is totally fixed. The screen doesn't turn on when I use my shoulder to hold the phone, which was my main problem before.

    This could change as I get some extended use, but as of right now, I am perfectly happy, and my PS issues have been fixed.

    Mine worked since day 1. And I didn't even know 4.1 already came out, I thought they were releasing it next week.

    The public build is out next week. He's talking about the GM.

    I did not fix mine either. I guess after the public release I will call apple for a replacement. This is becoming a real pain in the neck living with it for 2 months and apple keeps saying there is a fix coming hang on and now the fix is ever so slightly better. I am getting tired of making 5min or less calls hanging up on people and calling them back blaming at&t for dropping the call when its my phone that tried to dial someone else or facetime or mute!!! My old 3gs never ever did it once in the 8 months of ownership and I have this problem every call for 2 months! I guess this is not a phone for left handed people the antenna+prox sensor. I was doomed from the start

    Some people *cough* who have searched for 4.1 already updated/restored to it without being developers.

    Didn't really benefit though. Never had a proximity issue, Game Center currently has no games, and i rarely use the camera nor do i understand/care about HDR photos.

    I think 4.1 actually made mine WORSE... in the month that I've had the phone i think i've pressed one button with my cheek. After updating yesterday, 2 phone calls, 2 buttons hit while on the phone.. grrrr

    I'm gonna go against the grain and say it helped mine. It seems more sensitive to me and triggers from a farther distance. It used to be around a 1/4" or so and now it's more like 1". You can try it out with the voicemail to see the difference. I hope it is the fix because every time my dad calls me he's pushing random buttons.

    4.1GM dramatically improved my proximity sensor. I no longer mute, hit facetime, or end calls anymore.

    I'm wondering if its a hardware issue that is being addressed by a software fix.

    If that's the case, is a balancing act, to make it less sensitive, but yet not too much otherwise, it won't work at all.

    Mine works just fine after 4.1. I was having some minor issues before, which have all been fixed with the update. No more face calls.

    The code to get the proximity sensor status has definitely been tweaked in 4.1, so it might have improved or even resolved for many, but not all.

    Here's my take.

    As we all know, the proximity sensor has been shifted rather high above the earpiece to make room for the front-facing camera that now sits in its place on the left of the earpiece.

    Everyone's ear cavity is shaped differently. Some are shallow, while some are deep. And since the proximity sensor probably returns a true/false or on/off value, rather than a range (i.e. distance to boundary), everyone will get different readings, based on how it's placed to the ear.

    And since the proximity sensor above and further than the earpiece, it is bouncing off a different part of your ear than it would be if it was closer and left of the earpiece where you would naturally put your ear to listen, as it has been in the iPhone, iPhone 3G and iPhone 3GS.

    Perhaps the tweak coincides with the additional use of the ambient light sensor to get a "better" detection. Has anyone tried testing it in various lighting conditions? Proximity is one thing, ambient light is another, so we could be experiencing a bunch of different and varied results.

    All this is why I still was able to send my wife into speakerphone mode twice since I installed the 4.1 GM seed two days ago.

    I am confident that Apple will quitely introduce a hardware revision during this year's rollout. It's unlikely they will physically shift the sensor lower, however. I think they will replace the physical hardware sensor with a more accurate or calibrated one. If anything, a warranty replacement further into the year will yield a better one, but trying to swap it out at the Genius Bar now will be futile.

    In the meantime, I think Apple said with its engineers, "This is the best we can do, so it's sent out in iOS 4.1, but we'll keep tinkering away with it if we can get better results."

    I hope there will be a real fix soon, this is freaking annoying.

    If I still have problems, I will go to the Genius bar and get a replacement. It just sucks that this phone has had a few problems but ones that really affect the way I do things, i.e sensor. I muted myself twice last night on the phone with my girlfriend. Does Apple realize the wrath of a woman when they think they are ignoring you. It's terrible.

    Couple that with AT&T's tempermental and intermittent cellular signal and we might as well not have voice plans anymore.
