Why isn't the ambient light sensor working on my iPhone 4S?

I recently updated my device to iOS6. I haven't had any problems with my iPhone until last night. I noticed that my screen brightness wouldn't adjust in my room (lights off).  It usually dims down when I'm in bed. Could this be a hardware problem? Or a iOS6 bug? Thanks and let me know of you're having the same problem.

I have a similar issue, when i unlock the phone for usage, the screen goes dim.  When I go into the settings the brightness slider is in the same location but if i just touch it the screen gets bright again.
edited to add that this is after the iOS 6 update.

    I just bought a new iPhone 5 today and the Ambient light sensor is not working. What can i do?

    Ambient light sensors are not always perfect in their function. To test, go into darkened room, with screen OFF, Locked, tap Home button. Look at screen it should be normal for use in darkened room, turn on bright lights, the screen should brighten to help compensate. If your iPhone does not do this, then Restore iPhone with current iTunes on your computer. See if better. If still problem, make Genius reservation or set up Service and take or send to Apple for resolution under Warranty.

  • Can the ambient light sensor be used to control the monitor brightness?

    I have a 3-week old iMac G5-17 1.9 gig machine. It seems wrong that the ambient light sensor is only used to control the level of the power light. Cheap TV sets have had this feature for decades!
    Does anyone know if there is a way to apply the light sensor to the monitor?

    Hello! Contrast in universal access set to normal, precalibration ColorMath RGB reduce but not solve the brightness dazzling, calibrate profile in expert mode don't work (a friend cameraman with "good eyes" try calibrate a profile with mix result).
    I cheat calibration to reduce the brightness problem...
    Snow arround my house in Canada have the same "full white brightness" like my imacg5 20' and i put my eskimo goggle for snow to look at my imacg5 20' screen!!

  • Why isn't the radio tuning service working on itunes?

    Why isn't the radio tuning service working on itunes? I get an error message on all of our Macs.

    Maybe one of the 300+ posts about this in the last few days has the answer.  Browse the forum.
    If you wish to, you can report to Apple.

  • I have a new 27"ACD connected to a 27" iMac (2010) and cannot control brightness on the ACD. Also, the option to turn off the ambient light sensor is not available. Tanks for any help.

    I have connected a new 27"ACD to a 27" iMac (2010) and cannot independently adjust brightness on the external display. Also, the option for turning off the ambient light sensor is not available. The iMac has the latest updates according to Apple messages. Any help will be appreciated.

    No, Detect Displays had no effect. However, I made the USB connection from the ACD to the iMac after the system was on. Following a re-start, all controls are available. Thank you for your response.

  • Why isn't the popup blocker exception working for sites I have added? It still asks me to "allow" them.

    Even though I have added sites to the Exceptions in the Popup Blocker preferences, I constantly have to press the Allow button to actually go to the next window. The sites are staying in the Exceptions list and I can get there, but something clearly isn't working properly.

    I have been adding each domain name that pops up that's different from the original website and Firefox is still asking me to "Allow" it. Very frustrating...

  • Why isn't the Archer Season Pass working as it should?

    I would really appreciate an answer, Apple.  I paid $31.99 for the season, and now Episode 4 isn't downloading as it's supposed to.  If the problem is on FX's end as far as download approval (which it shouldn't be, seeing as it's up on the iTunes Store for download), that's fine, I'd just like to know where the bottleneck is and how to fix it.  Is Matt K. around? He DID just welcome me to the support community, after all...
    I know I'm not the only one having this problem, either.  Hopefully the flood of questions and complaints will encourage some action on Apple's part.

    Sigh. I too, purchased an "Archer" season 4 pass. I too, have been unable to download episode 4 w/out paying for it again. I emailed support and eventually received a polite reply indicating "Apple is currently working toward a resolution for the issue". I waited 24 hours and requested an iTunes Store credit.
    I've received no reply to that request, but I suggest we all request store credits.

    Thank you for posting.
    The code looks good to me. Only reason someone won't be opted in automatically is if they ever opted out from your site. If even new users are not getting opt in automatically, please contact our support as it may need some testing and investigation..

  • Why isn't the new Firefox instillation working on my PC?

    When opened PC today, immediately a Firefox bar scan popped up and was uploading new software without my consent. After it installed, I have not been able to get into any program or site. I can't even open my email and I had a client through the PC today which I had to cancel since programs are not responding. I am not happy about this at all.

    Can you boot the computer in Windows Safe Mode with network support (press F8 on the boot screen)?

  • Why isn't the enable prefetch command working?

    I shut off DNS prefetching to test an internet performance problem that I'm having....
    I then tried using the command:
    defaults delete com.apple.safari WebKitDNSPrefetchingEnabled
    ....in a Terminal window to re-enable DNS prefetching and I got this message after hitting enter:
    2013-11-18 20:21:24.479 defaults[359:507]
    Domain (com.apple.safari) not found.
    Defaults have not been changed.
    Any idea what this means?  Am I to assume that because of this error that DNS prefetching has not been re-enabled correctly?
    Thanks,
    John

    Hi Linc....Thanks.  I'll take your word for it......and I say that  only because I had just issused the command to disable prefetching right before I typed in the re-enable command.  So.....it should have been disabled.
    Instead of using the command above to re-enable it, I tried this one instead that I read about somewhere:
    defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean true
    .....and I got no error on that one.
    Is there a command that can be issued to tell whether pre-fetching is on or off?

  • Why isn't the clock app I love on my iphone on my ipad? It's not in the app store either....

    anyone know how I can get my regular clock app that came on my iphone on my ipad? if you can help can you email me? [email protected]
    thanks!

    thank, king, but none of them have all the simple elegant functions I was used to--the stop watch, the count down time, the multiple alarms. I tried one last night an never even heard the alarm. I use the other functions in my work on a daily basis. it's a loss and seems like a dumb choice on Apple's part!

  • Ambient Light Sensor Not Working Macbook Pro 13 inch early 2011 version

    Hi. I just need some clarification on how the ambient light sensor works. it seems mine is not working. Correct me if I'm wrong:
    1. Screen light must increase brightness if you are in a dark / dim room
    2. Screen light must decrease brightness if there is natural light
    What must be the level of light in F2? Should it just be in the middle to activate ALS?
    Am I correct or not?

    1. Screen light must increase brightness if you are in a dark / dim room
    2. Screen light must decrease brightness if there is natural light
    Actually, you are wrong. The opposite of each statement is true.
    If the screen adjusted itself to maximum brightness in a very dark room, it would be blinding. In a dark room, you only need a very dim backlight to be able to see the screen well.
    And in bright light, the screen is quite hard to read unless it is very bright.
    What must be the level of light in F2? Should it just be in the middle to activate ALS?
    I'm sorry, but I don't understand these questions.
    The ALS is always active. You can determine (in System Preferences) whether or not it will automatically adjust your keyboard and display backlights as ambient light levels change.

  • Apple iPod Touch  2G Ambient Light Sensor not working!

    Now I have a iPod Touch 2nd Generation which I was given for Cristmas 2009 and was really pleased with it and it has only been now that I have
    Noticed that the ambient light sensor soposedly built in does not seem to work!  It is on in the settings and other people have said that it only senses when it is woken but it does not even do it then!
    P.S. I do have a transparent screen protector on it although this should not affect it!

  • Toshiba - A665-S5170: ambient light sensor not working after recovery

    Hi all,
    Two weeks ago I bought Toshiba - Satellite Laptop Model: A665-S5170 | SKU: 1859059
    http://www.bestbuy.com/site/Toshiba+-+Satellite+Laptop+/skuId=1859059
    I tried to resize the C: partition using the recovery option. It works fine ending with C: partition (100 GB) and D: partition (480GB)
    All the divers and applications restored fine except the ambient light sensor.
    I used system recovery to out-of-box state, but still have the same problem "ambient light sensor not working".
    Would you please help me find a solution?
    Thanks in advance.

    I had the same problem. I tried resetting SMC but that didn't do the trick. Then I tried “Repair disc permissions“ and that fixed the problem.

  • M640 ambient light sensor not working

    The ambient light sensor on my M640-BT2N23 laptop is apparently not functioning, if it exists at all (the laptop's specs say it's there.) Whether I'm looking at the screen in a dark room or a brightly-lit room, the display intensity does not seem to change at all to compensate.
    When I check Windows 7's Location and Other Sensors control panel, it says that no sensors are installed.
    1) Does my computer include the ambient light sensor?
    2) If so, is there a way to activate it?
    3) If so, is it worth the effort?

    In the iPad, open the Settings app and drag the brightness slider to 50%.  While 'Brightness and Wallpaper' still open, go to a bright source of light (window, lamp, etc.) and see if it changes; now go to a dark room and see if the button starts to slide to the left (very slowly; really, now it's very slow).  Put the iPad to sleep (Still on brightness and wallpaper) and then wake it up again and see if the position of the slidebar changes.  Remember that now the ALS behavior has changed and now it works like in OS X.
    If you don't see any changes, then it would be time to consider a restore of the iOS via iTunes:
