My iphone screen goes blank during a conversation

When I am talking the screen goes blank and I cannot shut offf the call when i am finished. The screen does not respond to touch at all. When I push the shut off button it seems to reset the screen but the screen flashes on and then off so fast i can't shut off the call. i have to push the shut off button several times to get it to come back on.

    I have a similar problem, when the phone is to my ear the touch screen remains active, sometimes this causes issues by my ear touching the mute or speaker button on the screen, when i then move the phone to cancel the mute/speaker the screen goes blank and I can't get the screen working without ending the call, this is annoying if the person on the other end of the phone can't hear me.

    I have the same exact problem both with my phone accidently muting and the screen going blank. so far the solution I have found is covering the light sensor at the top just above the speaker and this will bring the call back. It is like my light sensor is working backwards.

If a hard reset (press menu and center button together for 5 sec) and software restore doesn't cure it , you have a broken proximity sensor or a broken logic board. There is an iphone repair website that shows you how to do the replacement yourself and a third party iphone repair company that can do it for you.

IPhone 4S shuts off randomly.


download itools get the latest one in the software there is system check crash report have a look on that it will tell you everything your phone is not doing, also when you install a new battery make sure the battery is flat, the screen should of come up with red line some batteries have charge in them and this can confuse the phone, another thing you can do is backup phone and do dfu setup, ios 8 sometimes has a problem and will need to be reinstalled new only do this in dfu mode, connect phone to pc etc and hold down the power button and home when the screen goes blank count to 6 seconds and then release the power button but hold down the home button for about 10 seconds or longer or until you hear the pc beep and install the dfu drivers. itunes will say that the phone needs updating do that, when finished don't do the setup , leave it for a few minutes then turn off phone leave off for 6 seconds then turn back on and continue with the setup it should be fine then, failing this and it still does this then the charging chip needs to be replaced, this is not a job for the layman need to be done professionally. hope this helps.

My iphone wont open my messages


If you go to you're contacts then go to a contact and say send message it will bring you to a conversation, hit back and it will bring you to you're messages, don't open the conversation with the long message though, delete it.

Since this morning, when making a phonecall, others are unable to hear me and I am able to hear them. I have the IPhone 3g. Is this a known problem? What can I do? I'd appreciate any help.


I have about 65 iPhones in my organization that I manage. I have had a few of them have this problem. It seems that the microphone at the bottom of the phone goes out/goes bad. Usually the sound through a bluetooth headset or the/a wired headset still works. The only permanent solution is to replace the phone. If you are eligible for an upgrade, I hear that the 3GS's are going down to $49 from $99 this month.

Hope this helps.

IPhone screen will NOT go blank during calls


Sorry but your proximity sensor needs replacement. Take it to the apple store and see if they'll give you a replacement. If they don't there are third party iPhone Repair Services that can fix it for you. There are also free iPhone Repair guide that show you how to fix it yourself.

Iphone 3GS- only get the apple loading screen.


If iPhone won't turn on, or the display freezes or doesn't respond
  1. Press and hold the Home button for at least six seconds, until the application you were using quits.
  2. If that doesn't work, turn iPhone off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a few seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
  3. If that doesn't work, reset iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears

More resets:
Try This:
1. Remove Sim Card
2. Hold in 'Home' button and 'On/Off' button together until Apple logo appears
3. Replace Sim Card
4. Hold in 'Home' button and 'On/Off' button together until normal phone screen appears.


Also, Try this:
1.) Shut down the iPhone 3G.
2.) Start up iTunes
3.) Hold down HOME button on the iPhone 3G
4.) While keeping the HOME button depressed, plug in the Sync cable
5.) A message will pop up to ask if you want to reset.
6.) Just click YES and the reset process should start.

Blank screen


Try a restore. Hold down home and power together until screen goes black. While holding down home button, plug it into your computer. iTunes should now recognize your iPhone and ask you to restore.

Iphone screen is black


Do you have a protective screen cover on the phone, if you do, you may have covered the proximity sensor at the top. MOst screen protectors cover the sensor causing them to turn off the screen during a call and not allowing it to come back on.

If you do have one on, take it off and try it without.

If this is the case, a Belkin screen protector tends to be the best one because it has the proximity sensor cut out of the plastic

Hope this helps
