    Default Screen blacks out during phone call won't turn on

    My wife's G2 started to blackout th screen when a call is made and removing the phone from your ear does not turn it back on. It has the quick window cse and if you open and close the small windows allows you to end the call. Any solution?

    Try not to cover the proximity sensor.

    Agree, or turn it off entirely. It's in settings (possibly in phone dialer settings or in phone accessibility settings).

    What those guys said...the proximity sensor thinks it is still up against your ear so it turns the screen off so you don't accident poke buttons whilst yer chatting. Mine has recently started doing this. I've found if I squeezed my phone, front to back, right under the front camera, thumb on front, forefinger on back, the screen would come back on...I downloaded the Phone Tester app and the proximity sensor was always 'near' until I did the squeeze then would change to 'far'. When you have trouble waking up the phone, even using the button, this works too. I got my phone the first week it was available and has only recently started doing this. The squeeze 'fix' makes me think the sensor is not quite close enough to the screen for whatever reason.

    The note 3 has these issues as well. I wonder if it is a bug. I got a replacement and it is fine now, but I don't know. That is highly annoying. If it happens again I will ask for a different phone.

    So this has been happening to me as well, and I was basically at the end of my rope until I figured out a "fix" (not a prevention). When your screen blacks out after a call and won't turn on, slide your finger slowly across the top of the phone (over the camera, speaker and sensor). Viola, screen turns on.

    This is obviously an enormous bug, but at least I no longer have to REBOOT my phone after every single phone call.

    Reply here with the results for you so we can see if it's a true work-around.

    (BTW I also have the low-light screen auto-turn off problem.)

    Default Re: Screen blacks out during phone call won't turn on

    I check the proximity sensor and found that its sensed about 6 inches away from the screen
    it is also very slow to turn on and off also the light sensor is off, in the dark my phone will not remain on
    very very annoying hope an update will fix also my phone has call severe quality issues other than that the phone seems to be pretty good

    running your finger across the sensor and camera was the only helpful thing on here, my phone blacked out and wouldn't respond to any of the buttons but was still receiving texts and notifications, I thought it was locked forever, so thankyou so much for putting that. ;]

    I have a Galaxy Note 3, and after installing the Rezound Proximity Sensor Calibrator and running it, no matter what change I tried to make, it kept displaying 'NEAR'. I then took my vacuum cleaner (that has a really strong suction) with the crevice tool attachment and vacuumed the sensor along and every other outward facing 'cavity'. This completely cured it. Then the Rezound Calibrator started to show 'Far' and as I moved my hand really close to it, it switched to 'NEAR'. I then retested by making a call to my home phone and as the phone got close to my ear, the display went black; as I pulled the phone away from my ear, the display went back on.

    This happened to my wife's GA. Just a light rub over the proximity sensor with a cloth or kleenex cleans the stuff that was blocking it (in her case makeup) and all is well again.

    Thank you for the tip...I've had 2 androids (swore I'd never get another one, because of the problem of screen going black during a call), and dummy me, bought another one...but anyways, I tested your theory...squeezing it...and it worked like a charm (after I got so mad at having to restart my phone when I couldn't hang up from a phone call, I threw the phone...onto carpet thank goodness).

    I just push the home button on my G4 and the screen turns back on.

    The Vacuum trick worked a treat. I removed the battery and vacuumed every nook and cranny or the phone with as much suction as I could. After that the sensor changed from near to far in the phone tester. Thanks for the info, it was pissing me off.

    For anyone who can't get it cleaned out for whatever reason, what helped for one of my phones with this problem was enabling power button ends call. Then when I touch the power button the screen turns on (but it doesn't end the call).
