Howdy.
On the Model: SM-N900W8" Bell Galaxy Note 3
Basically when in call, Here is a problem that is reoccuring for the past few weeks ever since a couple over the air (ota?) updates I have received compliments of google.
Enabled right now, via "call settings" = "Turn off screen during calls" is CHECKED with Green checkmark.
Just handset call, moving handset to ear to talk. Handset goes black. When removing handset from ear to click hangup, or press buttons, ie to "see" the screen... screen is continually black. - Fix = PRESS HOME BUTTON... brings screen up...
When on speaker phone call, screen is lit. Move hand to the first of 2 sensor circles by the main earpiece part, screen goes black, but does not return on.
I have tried *#0*#. = "Connection problem or invalid MMI Code". - However try again, and I get red green blue receiver etc etc.
I clicked "sensor hub test" and it went BLACK.
I had to click home button, unlock screen, and I get a white with black text stating that..
INT Check: OK
FirmwareCheck
MCU Firm Version : ST0113090300
Bin Firm Version : ST0113090300
MCU Name: STM32F401CCY6B
"blue letters" PASS
I don't see how it passed, a screen went black, did not return, just went black..
Hit the back button. Tried "TSP HOVERING". That works fancy, drawing green squares everywhere...
Under "SENSOR"
I move the hand over proxmimity sensor - ACD goes to 1000+ when I put my finger over it and the screen goes green with black fonts of the prox, acceler, barometer, lights, etc...
Prox is native when sitting still anywhere from 80-95 averages for ACD
Proximity is 0.0 and TSP Color ID: 00
The different tests are rather cool to try, but not helpful in solving my issue...
What I have done: Use a lcd led plasma tv screen cleaner from nexxtech for non streaking. A cloth that came to clean my glasses I have to clean the screen. It is streak free. I have used compressed air to thoroughly blow the area around the upper speaker / sensors and even had the battery out / cover off, etc and blown every hole around the phone.
I still cannot solve this issue of black screening.
The only resolution which leads my ear to "hang up calls accidentally" is to "un check" ie single box, no checkmark, the "turn off screen during calls" option.... ie disable that sensor thing...
I have hard booted, rebooted, cleaned, etc...
Suggestions?
I have the same problem, hoping I won't have to send my device to the service because it's a pain in my country and I will be without a phone for more than a week.
Anyone know any fix for this?

I plan on trying to return mine before re-calibrating via the above technique. Though I would like to hear peoples opinion on if its a calibration issue (i.e they didn't calibrate it from factory properly) or a hardware defect and the sensor it self is bad. My ADC value's when not covered sit at about 70 (clean screen after blowing with air at ear piece) My screen was solid green, wouldn't go white until I blew it out, I didn't check the value beforehand.
Went to Bell today and they will let me exchange it (backing it up now) I checked out the new phone they have for me and its ADC value is 30 with nothing close. From the link above it shows the "normal" value with nothing close to the proximity is around 10, not sure if I should be concerned with the new phone and try and find another if they are willing? Either way its better then my ADC 90 I'm getting today (blew with air yesterday to get it down to 70)
Thoughts? I would love to know a few more peoples ADC values.

I can't install superuser as i'm on a different model then the 2 common series out there... Unless you have some way to install root to correct...
It's more then likely difficult to complete without this...
well, I've had this exact same issue, but I read somewhere that if I blow into the earpiece (no air spray, I mean by my mouth, normally blow air into earpiece) it might get fixed. so I did and it is ok now it seems there might be getting dust under the glass through the speaker

I used a can of compressed air... and ADC went form 120 and non working proximity sensor to 10-15 with a good working proximity sensor.
I've contacted the seller where I bought my device (Omegacell somewhere in Alberta... for a SM-N900 imported from some other country)... they told me that if I can reproduce the problem, they will replace my device since I bought the exchange warranty at the same time. So now I'm back to square one... because I got it working with the air through the speaker "trick". Hoping that this fix will last for ever... but if it ever comes back, I hope that it will be within my 1 year exchange warranty.
Deep cleaning
I had the same problem with my proximity sensor. First it wouldn't work at all. Then ,after wiping the screen and blowing (with compressed air and mouth), it would work somewhat. The screen would go black when I put it to my ear but would not come back on after I took it down.
I tested it by dialing *#0*# and using the "Sensor" button. It would sense my hand approaching the sensor but not my hand going away.
I disassembled the phone following the instructions from GalaxyNote3Root.com (Sorry I can't post a link, not enough posts yet).
I wiped the sensor and the inside of the glass with a clean cloth, reassembled and the phone is now good as new.
This might obviously void your warranty, but on my AT&T SM-N900A there are no seals or tapes of any kind that has to be broken to get access. So no warranty voidage. At least no way anyone can tell you the phone was opened as long as you are carefull.
The whole operations takes about 15 mins.
My defy+ proximity sensor is not working.
As soon as I make a call, the phone screen goes black. The call goes thru fine, but the screen goes black.
No, I don''t have my finger or face near the proximity sensor.
No mods on the phone OS.
I did some debugging-
Cleaned the back of the phone by blowing air.
Tried the screw loosening like in the youtube video
Changed brightness settings from auto to manual.
Changed display turn off from 1min to never.
Finally, I downloded a sensor app and checked for change in the value of the proximity sensor when put by finger in the sensor area. The value was stuck at 3%, no matter what I did.
I was playing around and when I pressed the speaker area near the proximity sensor, the sensor value jumped to 100%
So I think the glass is blocking the sensor (or acting as a reflector).
Just to make sure the glass was the issue, I made a call by keeping the speaker area pressed. It worked as expected - no screen blanking after call. It does go black if I put my finger in the proximity sensor area.
I have no idea how to fix it.The screen & sensor need to be pressed closer.
Only thing I have tried is tighten the screws in the back. But no use.
Any help?
Since you don't have mods, it's probably broken, go to customer care.
Or you can maybe try factory reset
Do you have a screen protector?
Out yes remove it.
If not your sensor is broken.

Hi All,
My proximity sensor has developed a fault where by when making a call it switch the screen off as soon as the call in connected and won’t come back on even away from the face until I press the side power button or the person disconnects.
Now my phone is rooted with the knox counter on 0x1 which is warranty void so im guessing im stuck with it?
I have a tampered screen protector with Seido kick stand case.
Now I have tried the following.
1. Cleaned the sensor with screen cleaner and microfibre cloth
2. Had X-note v20 installed but have tried other roms and also original BTU UK Stock Rom
3. I have done a hardware test which turns green as soon as you go into it which indicates the sensor has been activated and won’t switch off (normal behaviour is for it to turn green when you hover you hand over the sensor and switches off when you remove you hand from the sensor) use: *#0*#
The phone was bought simfree from Uk retailer who has now gone bust (Phones4u)
Any advice and help would be appreciated.
Hi,
I fixed this issue using the following guide

Thanks
my issue seems to have developed again, just randomly. I read you have to adjust the value from default ones.

Hi,
Lately i have been noticing that the proximity sensor on calls on my s5 is not working properly. Once i answer/make a call, when i place the phone in my ear it shuts down the screen but the problem is when i take it away from my ear, the screen doesn't turn back on.
I tried the the testing menus (*#0*# or something like that) and when i placed my finger close to the sensor it detected, going green and vibrating but it doesn't go away from that state.
The only thing that changed was that i applied a glass screen protector a few days ago and im thinking it could be that, but its strange because its only when i back away from the screen that it doesn't register, so i don't know if that or not. Also, the protector is properly aligned and the edges are not on top of the sensor.
Anyone experienced this on their s5?

You have to change the proximity sensor or cancel it(cutting the flat)
I ended up removing the screen protector and it went back to working properly =/ I can't really put it back on now because it attracted specks of dust and it doesn't glue well now =/
Cutting it flat means it deactivate it? Because i find it useful for phone calls

Cutting it means deactivate fully, even in calls display stay on.
Hello XDA,
I think I discovered a weird feature or a bug when ever you place your S4 on top of a speaker. I have a portable Jam XT soeaker and when I place my phone on top of it, facing up the screen goes black only showing the tine and partial top bar.
Will attach screen shots.
Any Idea what I stumbled upon ?
Heres the screen, new account, sorry.

Go to imgur, fill the gap
The S4 has a magnetic sensor which works with the S-View cover.
The magnet in the speaker probably activates the sensor in the phone, thus the phone enters the S-View cover mode.
