Solution to Unresponsive/Blank Screen After/During a Call

Hi all,
I upgraded to iOS4 on my 16GB 3GS and for the past few days my screen has been switching off in calls and then not coming back on again when taken away from the face. This also left the screen blank, after clicking the power button 5 times it woke up, however the touchscreen was unresponsive. I would have to restart it to get it working.
I tried to search for a solution for this and there was advice about restoring and resetting the settings. I carried them all out but with no luck.
After a little bit of lateral thinking I had an idea.
So I took the screen assembly off and then the proximity sensor assembly. I then cleaned the glass where the proximity sensor "sees" through the screen. After this it has started working and hasn't failed once. I believe that it is because the iOS 4.01 update changed the sensitivity of the proximity sensor due to the problems with the iPhone 4's proximity sensor. And hence a slight bit of dust would alter the more sensitive proximity sensor's readings.
Hope this helps somebody, do let me know if my logic above is completely off.

1. On call, when you bring your phone near to your ear, the Proximity sensor recognises your ear and turn off the screen so that there is no unwanted inputs as the screen touches your skin. But when you pull it back, it turns the screen on again, but it takes 0.5-1 second to the Max.
If it takes longer, make sure there is nothing in front of sensor (it is placed on top left), like Plastic lamination, some accessory, dust or while you pull off your phone, your finger should not be there.
If it still takes longer, better make your device checked at Nokia Care. If found some problem, they will change the sensor.
2. The mail app is working perfectly fine for me on Wi-Fi. You should try loading some websites in browser, if it takes longer, check network strength, it should be strong on 2G internet (Personal experience- BSNL 2G, residing near Network tower, slow like hell, in INDIA). Try changing provider.

  • Blank screen after Ending a call on Asha 501

    I got a new Asha 501 last week. I am very happy with the product and its worth for the money spent.
    However, two issues i have noticed so far and its bothering me a bit
    1. after ending a call the screen goes blank and sometimes it takes a bit to end the call. This is very awkward during some important calls. would appreciate if there is any solution for this.
    2. Mail app takes a long time to load the message contents. I know 2g is not the fastest connection but still this is too slow even for 2g.
    best,

  • Blank Screen after Hibernate

    Hi,
    On my DV6-3085 I sometimes power up by opening the lid and get a blank screen after a few seconds.
    The screen will say Starting Windows, flash and then go blank. At this point the finger print scanner is still working and responds but you cannot obliviously see anything.
    I fairly suspicious this happens after the laptop has not been used for a little while (overnight) after a lid close, so the Sleep light has stopped flashing and the laptop is in hibernate mode.
    My guess is it is something to do with switching graphics adapters. I've not yet decided if plugging the power in first does or does not make a difference or being on battery or AC when the lid was closed.
    I've got the latest drivers according to the HP driver update utility.
    Anyone with the same problem or have a solutions?
    Thanks,
    Dean.

  • SAP BPC 10.0 Web Client Blank Screen after login

    Hi ALL,
    We are using SAP BPC 10.0 Web Client with Adobe Flash Player 13.0.0.214 with IE 9.0 on Windows 7.0.
    We face strange error where on only on certain PC, the BPC web client working.. On other getting Blank/Blank Screen after login (with "movie not loaded" on the adobe flash player).. Both PCs are having the same setting.
    Even one of PC which previously working, starting this week suddenly getting the same error.. I have created OSS message and got feedback with also share this problem on this forum.
    I have done several actions as mentioned on several SAP notes )1624267, 1664889, 1681147, 1694871, 1752971, 1798336, 1804221, 1806371, 1811218, 1820505, 1918631, 1968584), but still no luck..
    If you have the same issue, kindly share..
    Thanks and regards,
    Hery

    Yes .. Compatibility View also checked.. in several PCs, it is working well. both failed and working PCs have the same setting.
    Just found another weird: in one working PC, 2 different windows local-admin users login to the same PC for BPC-web and getting different result (1 Ok ; 1 failed) ..seems it is related with the user profile and login-domain servers (we have multiple login-domain servers with load balancing mechanism).
    Thanks and regards,

    Pavilion- a1130n"  WINXP ProfessionalC fails to reboot and shows blank screen  after automatic install ing windows updates including SP 3

    I would love to say that a refresh worked for me however it did not.It takes about 30 Minutes total I was able to trace part of the issue to a Registry Key that was tagging the processor. Because my BIOS manages its own temp gauge and windows is trying to
    build on in I had to turn the BIOS one off as well as for some reason I get better funtionality with Visualization off.
    I am still dealing with a lag but I was able to get ride of the freeze that made the computer completely useless.

  • Blank screen after KitKat update

    I just completed the KitKat update on an Ellipsis 7 tablet that's connected to Verizon's network, but now I'm only getting a blank screen after the welcome screen displays. Fyi: the first part of this update went smoothly. Can anyone can help me resolve this issue? I really like this tablet and use it everyday.

    I contacted Verizon support and a couple of techs attempted to walk me through alternate boot methods. However, as bassclarinetl2 noted, "pressing the power button to turn the device off results in the device powering up by itself and both 'safe mode' and 'factory reset' are inaccessible via their button combinations." Therefore, I'm sending my tablet in to be repaired or replaced under warranty. Depending on how long you've had your Ellipsis 7 tablet, you may be able to do the same.
    Incidentally, I have another (seemingly) identical Ellipsis 7 tablet and was able to successfully install the KitKat upgrade on this second tablet, which I'm using now. The sooner Verizon determines why the upgrade worked on one tablet and not the other, the better.
