Apple still searching for iPhone proximity sensor fix

iPhone 4 Accessories “Apple has yet to find a fix for flaws with the iPhone 4’s proximity sensor, according to one of the company’s Australian spokespeople, Fiona Martin,” MacNN reports.

“Normally the sensor detects when an iPhone is next to a person’s face, and shuts off the touchscreen to prevent people from accidentally tapping onscreen buttons,” MacNN explains. “In some cases the sensor is failing, potentially leading to interrupted calls.”

MacNN reports, “Apple is currently working on iOS 4.1, which could be released as soon as this week to support new iPods.”

MacDailyNews Take: We’ve been using 4.1 beta since the first release and we see no proximity sensor issues on our iPhone 4 units. Of course, we didn’t see any proximity sensor issues before moving to 4.1 beta, so fat lot of good we are on this one. Are you having issues with your iPhone 4’s proximity sensor?

  1. Yeah, having proximity sensor issues with newest phone (have had all 4 versions; this is the only one I’ve had problems with). Basically muting calls but sometimes hanging up on people when holding the phone between my cheek and shoulder (i.e. no hands mode).

  2. I experience the proximity issue, but not consistently.

    I can see the light from the phone in the corner if my eye, when it is not working correctly, and I’ve learned to adjust the way I’m holding it when it happens.

    On a couple ocassions, when I’ve let other people use my phone, they have managed to accidentally hit buttons, turning on speaker phone, etc.

  3. I only ever really make or recieve calls with the headphones; thus even if I did have this problem I wouldn’t know about it.

    Concurrently, this also goes for the whole antennae problem too.

  4. Yep, still having some issues but not as bad when on 4.0 w/my iPhone 4.
    I never had that problem on my 1st gen iPhone nor my 3GS even after I upgraded it to 4.0. I’m sure it’s associated with the gyroscope & the much more sensitive Retina display on the i4.
    If I’m using it outdoors or in a situation where it’s very hot & I’m heavily prespiring it’s always tough but that was on all models not just the i4.

  5. I’ve had problems with iPhone 1, and now iPhone 4 with “face dialing”.

    Only when I try to cradle the phone between neck and shoulder does it happen ..

    My solution is to not cradle the phone.

  6. I have had lots of proximity sensor issues with my iPhone 4. I “face dial” people too often and have muted the phone quite a few time. I am learning to keep some extra space between my face and the phone when talking.

    It is disappointing when a feature that worked flawlessly in the past becomes flaky. A key aspect of quality management is to prevent backsliding. The good news is that this does not appear to be a universal problem. The bad news is that might point to a hardware/fabrication/assembly issue rather than a software fix, which would mean replacement iPhone 4’s. Want to bet that the media will make a huge stink if that happens?

  8. For me the antenna thing (have that too) is inconsequential compared to the proximity flaw. I mean I love my iPh4, but I cannot make a call without one of the functions interrupting the conversation, usually the mute button. I’ve tried various ways of holding it and nothing helps. Never had that problem on any of the other three iPhones.

  9. I’ve had this issue with two iPhone 4s. Apple replaced my first iPhone 4 because it was so bad. My new phone started having the same issue after three days. I did not have the problem with my 3G. I’m a loyal Apple customer, but if my first iPhone was the iPhone 4 and had this experience, I would honestly be pretty disappointed. I hope the fix comes soon.

  10. My wife is on her third iPhone (1stGen, 3G, and now iP4) and she has been wildly enthusiastic about the device…. except for this persistent Proximity Sensor issue in the iP4. It is driving her to almost exclusively use her Bluetooth headset because if she doesn’t, the failure of the sensor continues to interfere with her phone calls.

    I’ve done a factory-settings restore, etc., with no improvement in the problem. In talking to Apple Store folks, there are definitely phones that don’t have this problem, so we are probably going to ask Apple to give us a new phone to try.

  11. Yes. It sucks. If I ever try to put the phone on my shoulder and hold it with my ear to talk, I almost always end up hanging up or muting the call because the screen comes on. It drives me nuts. My 5 other coworkers are having the same problem. I hope they can fix it.

  12. I have had problems with this since day 1. Most of the time I just use Skype to make calls so I can lock my phone w/o having to plug in headphones. If Apple would just allow us to lock that damn phone w/o having to use headphones or speaker it would not be a problem for me. As far as talking on the phone this proximity issue has made my phone worthless for talking! I really hope this is addressed and fixed, sadly I don’t think it can be, why else would Apple let several updates go by w/o addressing this problem!
