Issue with Proximity Sensor during calls

I'm having an issue with the Proximity Sensor not properly detecting when i'm holding my phone to my ear. I can confirm that the iPhone sensor is working by covering it with my finger, but when held to my face, the screen blinks as if it cannot decide to disable the screen or enable it. It results on me hanging up, putting calls on mute, and dialing numbers accidentally while i'm on the phone. This occurs on 90% of my calls. Is anyone else experiencing this issue. I would like to confirm whether this is a software issue (Proximity Sensor sensitivity too low) or a design issue (sensor now placed towards the end of the phone).

Macbook Pro, Mac OS X (10.6.4)

I'm not an Apple Tech specialist... BUT, it seems to me that this MIGHT be a software issue.

The Proximity Sensor WORKS, in that, when I bring the phone to my face, the light goes off. Just like my 3G. So it KNOWS what's going on.

The problem is that it doesn't use that information to 'turn off' the button-pushing ability.

Again, not a software/hardware engineer... but...

My 2 cents :P

I just spoke to a Sr. Level Advisor at Apple regarding the same issue everyone else is dealing with.

I actually told me that this IS a known problem, along with the antenna issue, and Apple is currently working on a fix for this.

I have already returned 1 phone and the 2nd one has not been any better. I truly hope this is resolved soon..otherwise I am going to wait another 14 days, and return it again. Maybe if I can hold out long enough the White version will finally be available, and I will get that one.

Same problem for me. I went to Apple store the Apple genious laid the phone on the counter & put his finger over the sensor, watched the screen go off & said that there is nothing wrong with the phone.

This trip to the apple store was a 45 min drive each way, plus the 2 hours I spent on the phone with the tech people. *Apple store is a waste of time.*

People, where exactly is this sensor located on the phone?


Hi Acblue,

Below's a repost of something I put-up earlier in this thread which I hope answers your question. Hope it helps.

R.

The detector appears to be an IR transceiver. It can be visualised using a digital camera or camcorder screen, as their detectors extend into the IR range. On my 3G (and on 3GSs I surmise) it is slightly above and a few millimetres to the left of the ear-slot. On the iPhone 4 it is just above the ear-slot and very slightly to the left of centre. I'd post a picture of it if I knew how to 🙂

The sad thing is that Apple could've largely put this thread to bed after about five or six pages of posts if they had just come out and acknowledged the problem and stated that they were working on a fix.

Unfortunately, dealing with Apple support on the issue is like playing a game of roulette. There's a 95% chance you'll get someone who has never heard of the issue and a 3% chance you'll get someone who says that he's talked to one or two other people who have mentioned the problem but Apple knows nothing about it and a 2% chance you'll get someone who actually acknowledges the problem and says Apple is aware of it.

Apple has employees giving consumers the run around out of ignorance. That's the problem with not acknowledging a problem at a management level and developing an official stance on it. Steve Jobs and others in management at Apple are making fools of themselves by releasing arrogant statements telling consumers that they don't know how to properly use a phone.

I just wanted to share my experience with this issue....

My Proximity Sensor was not working AT ALL, totally dead, like it wasn't even there. I did ALL of the suggestions on this forum, including 'Reset All Settings', 'Reset Network Settings', 'Restore from Backup', 'Restore without backup', etc.

I called Apple and they said, "It's a hardware issue. Schedule a Genius Bar appointment and get an iPhone exchange.". I did that and got a new iPhone 4. No fuss, no hassle from the Towne Square Apple Store, here in my not so humble home town of Las Vegas, NV.

The device is working perfectly, none of the flakey issues that I see being posted here.

So, it seems that for some units, it is DEFINITELY a hardware issue.
