When I am in a call, putting the phone to my face turns the screen off using the proximity sensor. However, removing the phone from my face does not turn the screen back on. Nothing turns it back on even if I push all the buttons or hold them or do anything unless the other person hangs up. I cannot remember when it started....before or after the recent update.....but it did start very recently. Any ideas? If I turn off the proximity sensor during calls it works fine by locking and unlocking the screen with the buttons.

Is anything covering the front facing camera, or light sensor? Like a case, bad screen protector, etc....
Does your front facing camera work just fine as a camera?
How about air gestures? Do they work?
I'm asking these things because it seems your proximity sensors aren't working properly. Your phone thinks it's next to your head all the time, so it's not waking the screen until the other person ends call. We need to find out which one is acting up and why.
The front camera works, but in my office it seems VERY sensitive to light. The lights are glaring heavily. I never use the front camera so I don't know if that's normally how it was. Air gestures work when the screen is on (swiping left and right to view my photos), but the quick glance won't work when the phone is locked. The weird thing is that quick glance works when I do the "try it" tutorial only.

Ok now it seems quick glance DOES work when the phone is off....I just couldn't do it correctly.
Main problem still exists though.

Unfortunately this sounds like a bad proximity sensor. This can be verified by testing the sensor by dialing *#0*#
I had this happen to my last Note 3. The only difference was I could turn the screen back on with the home button.

I tried that *#0*# test and I can activate the proximity sensor, but it seems to stay on after that.
This is a known issue with our phone. I had this issue myself. Plenty of times. Just call ATT and ask for a replacement.

I just bought a Galaxy S from ebay and am facing this problem. Everything works fine on the phone and it doesnt look like there is any water damage. When I try to make a call the screen goes completely blank. I cannot disconnect the phone or do anything since the screen is blank. The only thing that I can do is remove the battery and install it again. Based on my research it seems like its a proximity sensor. I even went ahead downloaded Z-deviceTest and all hardware seems fine. I also upgraded to the official 2.3.3 from Samsung so I dont have a custom ROM, no root nothing! What can it be? Should I ask the seller for a refund or there are any tweaks for it. Any help is appreciated.

I'm not an expert, but seems related to a faulty proximity sensor indeed...

I am pretty positive that it is the proximity sensor as when I insert the headset calls can be made without the screen going blank. I dont have a screen protector and I tried to put some compressed air to see if that changes anything.
When making a call and the screen goes blank can you cover the proximity sensor for a while and see if its turning on the display? I kinda have the same issue sometimes and covering the sensor would normally do the job.
Sent from my SGS using XDA Premium
Same problem here, seems that plugging headset does the job. It is kind of lose or lose situation, even turning off (any idea how?) proximity sensor would not help as screen would be touched by ear Any other solution anyone? Or some kind of calibration? Check? Most applications from marked I have checked are crashing or showing 5cm from sensor regardless.
Does anyone else have problems with the screen not turning off when on a phone call? Mine doesn't turn off unless I directly cover the proximity sensor with my fingertip. I believe it has been this way the whole time I've had the phone, but maybe it's been worse since I went to ICS. I'm on Dark Raider right now.
I have been turning off the screen when in a call, but it would be nice if the sensor just worked. Is there any calibration tool available for the vivid? Or is this probably a busted sensor? My fiance's vivid also does the same thing.
I get the opposite. The screen turns off when put on my ear but doesn't come back when taken away from ear. Very annoying when you're dealing with an automated teller. Anybody know know anything?

. . . and I have to hit the power button to turn the screen back on. To be more precise, the screen turns itself off when I hold the phone towards my ear during calls, and it does not turn itself back on when I hold it away from my ear.
This is obviously some power saving feature that doesn't work as well as it should, like a gimpy proximity sensor. Anyone know a workaround for this ?
I'm on Three Musketeers Sense 3.6 ROM.

Well, ther is a proximity sensor there, near the camera on the top of the phone, on the screen side, and this screen-off thing is more like feature to save power and not to anoy you during the night when you talk to the phone
Don't know why it does that, maybe your sensor is faulty, but try to flash a different ROM and see if something changes, also make sure you don't keep your hand or finger near that sensor, just to be sure, i personally use this ROM and i don't expierience this issue.
Hope this helps

If it is possible on Galaxy S2, then it is possible on any android phone , and it is, but there should be made a tool for that or a flashable zip, i'm not that experienced to tell you exactly what needs to be changed, but it can be done, that i know

Changing roms didn't solve anything
Anybody have solution for this ?
If you have a screen protector covering it then it might be wise to make a cut out or take the protector off altogether.

as i remeber , you can write something in the build.prop that will disable proxy sensor
Im having problem that is almost same. After a long call(when screen is turned off) it turns off but screen or softkeys dont reply any way.
I have to turn of the screen with power button and let it be around 10-15 seconds and turn it on. Then lockscreen appears and everything
works. This is really annoying because I cant cut the line any way.
Not using screen protector and tried couple of custom roms. Allways have the same issue.

No I don't have screen protector or cover.
Problem is identified with proximity sensor itself, on App " Android sensor box " if you select proximity sensor it reads always 0.0cm no mater what you do with phone.
It seems like HW failure, will have to look at it in more detail.

The problem is when you try to make a second call display turns off, phone is working you can talk, but you can't end the call or nothing because screen is off, so you have to turn it on or wake it by pressing power button.And it's happening only on every second call, so I make a first call, as soon as I try to make a second display turns off, and only power button wakes it, after that you can make the next call normaly, but problem repeats on second call.
Phone was stock on ICS 4.0.3, and making problems there. So it's now fully unlocked ( S-off ) Hboot is 1.28. I have tryed many custom roms, but the problem repeats
I think it's the hardware problem with proximity sensor.

To continue the story, I removed the MB and when the proximity sensor is out of the case, it works ok. When I put it back in case( behind screen ) it doesn't respond again.
Cleaning didn't help, will have to find another one to make sure what is the problem.
I have fixed my problem thanks to this thread
http://forum.xda-developers.com/showthread.php?t=2022865
There seem to be several proximity sensor threads but I've done a search and have not found anyone that is having this same problem.
When I make a phone call, my screen turns off right away. I can only get it to come on by pressing the power button or tilting the phone so that a bright light or glare is on the proximity sensor or light sensor. This is a pain. I use my power button to end calls but I have to disable that option. Otherwise, any time I need to use touch tones for an in-call menu, I hang up or spend a minute tilting my phone or holding it up to a light bulb. I know there are workarounds that I could be using but I am wondering if my proximity sensor or light sensor is malfunctioning or if it is a software issue.
Also, when using the visual voice mail app, my screen goes black but not off. I can still see the status bar. It happens as soon as I tap the play button and works just fine after my voice mail stops. This is likely unrelated but I can't be sure.
Thanks in advance to anyone that helps!
Running stock and unrooted with no physical damage or obstruction of sensors. I have tried a factory reset... twice.
I'm having a weird issue with mine as well. Mine is a little different though. If I need to make a call that requires to enter # prompts and as soon as I move the phone away from my face the keypad will start beeping on the other end so the prompts will always get invalid responses. While on the phone and I move the phone away from my face for any reason, the person on the other end will hear the beeping.

It sounds like your issue is hardware related. Take it to a sprint repair store and have it exchanged.

You issue also sounds hardware related. The touchscreen sounds like it is going out. It might be the dialer app but I doubt it. Speaking from experience of course.

I would check the sensor settings and play around before trying the store. But if that doesnt work it prob is hardware issues
I multitask all the time on my Note 9. However when I try to use the screen when I'm talking on the speakerphone (for example, look up a phone number or web browser) the screen turns black immediately when my hand covers the proximity sensor. This is especially an issue since I hold my phone in landscape almost all the time (my left hand covers the proximity sensor). I'm baffled why Samsung would want the proximity sensor to turn off the screen when talking on the speakerphone... with no intuitive way to disable this.
Seems kind of odd considering this phone is meant for busy people who multitask. I've already spent a lot of time looking for a solution for this... but, haven't found a solution yet. I've already tried "Kinscreen" and "Keep screen on" on Google play. However, it doesnt work on the Note 9.
So... what's the trick to disable the proximity sensor on the Note 9?
Saw the below article by searching on Google... However, it seems to be a bogus website with false information:
https://gettechmedia.com/how-to-turn-proximity-sensor-on-off-samsung-galaxy-note-9/
PS: I have a Verizon phone.. so I can't root it either.
Sounds like a screen protector or similar may be causing an issue with the proximity sensor
The screen isn't supposed to turn off when on speakerphone, mine doesn't
Sent from my SM-N960U using Tapatalk
Thanks for the reply. I probably should have mentioned that the proximity sensor works correctly. If I move my finger over the sensor, it blacks out the screen. If my don't cover the sensor, the screen turns on immediately.
I think that's how the proximity sensor is supposed to work by design. This functionality is in place so that when you move your ear to the phone, it turns the screen off.
The problem I have is this that the proximity sensor turns off the screen if I accidentally move my finger over the sensor; even when I'm talking on the speakerphone (when my phone is not near my head). On older versions of android, there's a simple setting to turn this functionality off under Phone/Call Settings.
Could you please check to see what happens if you move your finger over the actual proximity sensor when the speakerphone is on?

I'm almost too embarranssed to say what the real problem was. I guess I'm more tired than I realized. I just noticed I didn't actually have speakerphone turned on. I guess the phone speaker is so loud that I thought the speakerphone was enabled! Thanks for trying to answer my question anyway.

Verizon N9. Screen goes black when on speakerphone after 10 seconds.
No screen protector. No proximity sensor issues. This is after I hit the speakerphone button (unlike OP that didnt know speakerphone wasn't truly engaged)
How do you get the screen to stay on when using speakerphone?
Again - this is NOT a prox sensor issue. The prox sensor works great when I am using it against my ear/face and not using speakerphone.
Same issue with the s10+, screen goes off after some time on speakerphone same as note 9.
