My LCD does not turn off during the call. I have a iphone 4. What do i do?

You may have a defective proximity sensor but try some basic troubleshooting first...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
If still a problem restore with your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
If still a problem, it's likely a hardware issue.

  • Imac  27" does not turn off

    Hi,
    I have a brand new iMac 27" all in one, which works perfectly except for the fact that 3 times out of 4 it does not turn off with the normal command and I am obliged to turn it off with the back switch, after it remain for various minutes  with the blue window on and the wheel running.
    Initially I tried to disconnect an external HDD which was connected by USB and seemed to have solved the problem for a few days, but now the problem shows up again.
    At the moment I have connected only a Bamboo device on the USB port.
    I have tried to Verify the HDD and repair the disk, but no improvement.
    Any suggestion on how to proceed?  Thank you
    SS

    If all the prior steps have not resolved the issue then at this point I would suggest:
    Remove any additional memory you may have added to the system
    Reinstall of the OS: http://docs.info.apple.com/article.html?path=Mac/10.6/en/8177.html
    If the issue persists after you follow the above steps, you may wish to make an appointment with a Mac Genius at an Apple store, contact AppleCare via phone, or contact an Apple Authorized Service Provider for assistance.
    If this issue was occurring right out of the box on the brand new system without you adding any additional software / migrating data from an older Mac, be sure to let them know that as well.  Its unusual to have a blank, brand new system have this kind of behavior so that will save them some diagnostic steps.
    Best of luck to you.

    Try a reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider if that appears.  See if that clears the glitch.

  • My iPad is frozen. Does not turn off or charge just black screen with logo. Tried to reset by pressing the two buttons and nothing.

    My iPad is frozen. Does not turn off or charge just black screen with logo. Tried to reset by pressing the two buttons and nothing.

    Then you should try restoring the iOS software next. Read this and pay attention to the last part of the article that describes recovery mode, you may have to restore your iPad that way.

  • HT201412 My ipad does not turn off...i tried pressing the Sleep/Wake button and Home button for 10 secs but no response. Also, the screen is not rotating on portrait or landscape view...any suggestions?

    My ipad does not turn off...i tried pressing the slep/wake button and home button for more than 10 secs but nothing hapened. Also, the screen is not rotating on portrait and landscape views...

    While this could potentially be a hardwar issue:
    Try a rest: Simultaneously hold down the Home and On buttons until the iPad shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the iPad back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray before doing the reset.
    If the reset doesn't work, you may need to consider restoring the iPad to factory settings

  • I just began using my Apple iphone4 and I dont know why the backlight does not turn-off timer does not exist anywhere that I can find. So my battery gets drained when I'm not using my phone. Does anyone know how to adjust it?

    Does anyone know why the backlight on my iphone4 does not turn off automatically?

    It's called "auto-lock" - adjust the time in the Settings app to a lower amount.

  • My imac does not turn off !

    My imac does not turn off ! Since i bought the imac ( february ) i had this issue
    I have called aplle support and During 2 months nothing changed ! I rebbot, i cleaned the cache i mean this
    Is the way apple slove issue. ? My imac does not turn off ! I have to turn it off by myself ! ( hold the power button )
    Everytime !

    It was before i install these apps.
    I would like some help ! And suggestions. I will return my imac and hope to have the new one because
    Since i bought i can not enjoy the Apple product.
    Thank you

    Have you done the safe boot mentioned above?
    Can you click on the apple on the left of the menu bar? Did you try Paul_31's advice to choose force quit to see if there are any applications that are not responding?
    I tend to agree that it may be time to take it to an Apple service center for hands-on attention.
    Apple normally doesn't replace a machine with a new one unless they have been unable to repair an issues(s) after several tries.

  • Imac does not turn off.

    hello,
    I have an imac, running on os x lion. u know how, when you click on shutdown, it shows the white screen. sometimes my imac does not turn off and keep showing it. could you please tell me what i can do to solve this problem.
    thanks

    The safe boot more or less resets system files.
    When it is something in the hardware:
    1.do the Pram and the SMC resets:
    http://support.apple.com/kb/ht1379
    http://support.apple.com/kb/HT3964
    2. shutdown the mac and startup while holding the ALT(option) key: choose the Recovery Disk, from the window choose Disk Utility, select the Lion disk, choose "repair disk".
    When it is not a hardware problem:
    3. List the applications you installed in the last 6 months, also the ones from the Appstore.
    4. List the plugins (extensions) you have in Safari.

  • Screen does not turn off near my ear

    The screen backlight does not turn off when you place it near your ear. Anyone else have this problem?

    What I found, especially with my Boxwave case (that iLounge didn't give high marks for), was that if you hold the earhole up directly to your ear, the screen does turn off.
    I checked and rechecked it in the mirror, and if I deviate a few cm higher or lower, then no, it won't. But if it's right up to my ear, then it does.
    By the way, I love the Boxwave case. The leather foldover protects the screen when sitting in my brief case.

  • What do I do when iPad 3 does not turn off?

    What do I do when my iPad 3 does not turn off?

    Try a device reset:
    Device Reset (won't affect settings/data/music/apps/etc)
    1. Press and hold (& continue to hold) BOTH the Sleep/Wake button & the Home button.
    2. Continue to hold BOTH (ignoring any other messages that may show) until you see the Apple logo on the screen.
    3. Release BOTH buttons when you see the Apple logo and allow the device to boot normally.

  • Sound does not turn off when switching between AppTabs, ie Pnadora to other radio stations

    I have several radio stations (Pandora, NPR, etc) as Apps Tabs, but the sound does not turn off from one when switching to another.

    Thank you. This is precisely the type of solution I was looking for.
    My home network is set up with a single router that assigns DHCP addresses and does the NAT to the internet. This router does not have wireless. Its location is too out of the way (given where Comcast brought the line in) to be any good at wireless broadcast. So I installed two access points on the wired network.
    I had vaguely known something about using the same SSID on the multiple base stations but I had also heard of difficulties a university reported having some years ago.
    In any case I made the switch and it works great. I get full bars on the icon on the menu bar as I walk around the house. Exactly what I was looking for and no manual intervention once I set it up.
    Thank you.
