    When I answer a call on my nexus 4 the screen goes black. So cannot end the call or view who is calling. Having to switch the phone off to stop it. Any ideas folks as its very frustrating.

    Does this happen before or after you have put the phone to your face? In other words, is the proximity sensor a suspect?

    Thanks for answering
    Just tried again from another mobile. It is mainly after I put the phone to my face
    I am unable to stop the call after I have answered it as cannot see the screen
    Pressing the on and off button shows the screen very faint But it goes again:thinking:

    Try to clean your screen and make sure if you have a protector installed it doesn't cover the sensor.

    Do you have a screen protector on? This happened once to me with a Lumia.

    i had the same problem, it is because there is a sensor on the top left corner if u notice, if u pull the phone down like u are on speaker phone so that nothin is close to the sensor the screen will pop back on, i thought my phone was messed up too haha. but its actually just a cool battery saving feature

    Not just for battery, it's mainly to avoid touchscreen inputs with your cheek.

    If the phone screen does not come back on after you take it away from your face, assuming you are not covering the sensor with your hand, then I would conclude the phone is defective.

    What happens when you hit the power button when you finish the call? This should switch the screen on.

    Pressing the on and off button shows the screen very faint But it goes again
    Then seems to reconsider and the screen comes on
    But dont want to be hanging on
    Where is the sensor then?
    All new to me Had a HTC before
    Only prob with that was sometimes it would not let me drag the screen down to answer
    Now I can answer but not stop lol

    I think you're phone may have a problem with the proximity sensor. This sensor is located very close from the earpiece, but it is not easy no notice. You should contact google for warranty.

    There is an option to end calls with power button in accessibility settings.

    You never said whether you had a screen protector, which seems to be the common source of this problem in the XDA thread. Basically, it comes down to this, in my mind at least. If the proximity sensor (essentially a light sensitive sensor) isn't being occluded, you have a defective unit and should return it for warranty repair. Work arounds are going to get old really fast. :)

    I just noticed this happened to me yesterday. No screen protector. That being said, Ive flashed a new kernal every day practically and ROM every other day. I can deal with a black screen with the amount of hackery Ive done with this thing.

    I have a similar problem, there is definitely something weird with this phone and how the proximity sensor works compared to all of my past phones, I have not found a pattern because I tend to try to ignore these things because they frustrate me. I do not have a screen protector.

    I love the phone (not as much as my nexus 7 though, bought it because of that)

    Today it has been behaving so touch wood.

    I was having this issue, very frustrating when you try and take calls on speaker in the car.

    I resolved the issue by snipping off the top 1cm of the screen protector, it works fine now.

    The sensor must be in the top section somewhere.

    I am soooo glad to see that I am not the only one having this problem. My husband and I have the same phone and his it not having the problem at all. Every time I make a call the screen will go black and there is no way to get it back on again. I am constantly having to turn the phone off and wait to have it reboot with every call ;( My husband was trying to tell me that I had to hold it a certain way, but I have tried everything short of jumping on one leg to try and get it to work. :thinking:

    I have the same problem with the screen off after a call and no ability to hang up.

    The Power Off button can be pressed to end the call.

    Selection :- Settings, Accessibility, "Power button ends call"

    I think that if the screen doesn't come back on, you've checked your settings and there is nothing blocking the sensor you should get a replacement right away.
