Proximity sensor - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hello!
For some odd reason my Proximity sensor stopped working.
Dialed the code for proximity sensor test and I found that the sensor is working,but when I make a call the screen doesn't turn off.
Also I booted into safe mode and the sensor still doesn't work.
Any suggestions?

Tried a factory reset,and still no luck...

Are you by chance using a 3rd party dialer like truecaller etc?

I've noticed this started happening since the latest firmware update, my screen kept turning on in the middle of a call, report to Samsung and wait for bug fix

Yes ,I was using true dialer, but after the factory reset I am using the stock dialer app.

[REQ] Disable proximity sensor (blank screen when calling)

As you guys might have read my display got broken and i replaced it myself. However in the process I damaged a few thing. The home button does not work and the proximity sensor is broken. The problem with the proximity sensor would just be fixed by disabling the blank screen when calling. Can anyone make a odin package (cannot do update.zip due to broken home button). Or tell me how to disable this function?
Many thanks in advance!
Mine is broken too and now everytime i'm calling the screen turns black. Which is no problem except when you are calling a computer a needs to "2" to proceed.....
Does someone have a sollution?
See this post. it may help, but you need root.

SOLVED.
Used the free app ProximityScreenOff. Its in the market.
Make sure you select the Proximity sensor instead of the Light sensor in settings.

Dosen't solve my problem with screen turn off, during call.
I have a default proximity sensor, which I need to disable.
I can do it, very easy with miui rom.
But I have tried and tried with Cyanogenmod without any luck.

Proximity sensor red faint red light always on now

Proximity sensor red faint light always on now , randomly turned on not sure why....
I have no motion things enabled
I tried turning off proximity sensor for phone
Ive rebooted several times
Ive turned off auto brightness
Im running the stock s3 rom rooted.
Anyone have any ideas how i can fix this?
Hmm.. My quick research of this makes me think you have a rogue app, a sticky setting or a defective sensor.
Let's be sure we're looking at the right thing. Your faint red light is just to the left of the front camera lens, correct? If so, then it's a definite indication that you're proximity sensor is on and constantly taking a reading.
Is it always on, from power on to power off? Or does it turn on once the phone has booted up? Does it stay on long after the screen shuts off during idle?
This sensor is used by motion features and talking functions. Triple check that you don't have 'smart stay' turned on, or one of the other super cool gs3 features enabled. I'd consider turning them all on manually, rebooting and then turning them all off followed by another reboot.
Lastly, take a look at your apps. Any kind of app that involves motion or talking (Voxer, Skype, certain games etc) can activate the proximity sensor and keep it on. A lot of those apps start on boot and never go away. Close them one at a time, or consider uninstalling suspect apps temporarily.
As a hardware test you can install Elixer2 from the play store (for free). Its sensors section allows you to turn the proximity sensor on and off, as well as test the near and far readings. If all else has failed, it might be nice to know that at the very least, your sensor can be turned off.
Report back with results from everything and we'll go from there.

Well i was using Viber, when i turned it off manually, the red sensor light went off. So it must be ab application that is keeping that sensor on all the time. Smart stay does not need proximity sensor and enabling or disabling it causes no change to sensors. Hope this will help ya

Thank you so much for the awesome response. I didn't find any other similar responses on the Internet other then " oh that's just the ir sensor don't worry about it". I too have viber and I believe that was the app causing the issue because of the way it integrates itself with the phone, can't be certain because so many apps updated as of late but it is gone now thankfully.
I get this when I`m in a dark room. The sensor will turn on. The only way to correct it is to restart the phone.
Plausible Solution
I don't know if this works 100% of the time, but it HAS worked for me. Go to your Viber application, menu, and then EXIT the app. Viber seems to be the culprit, so if you find exiting the app manually every time bothersome, you might be better off uninstalling the thing. Click the Thanks button if it helps =p

Disable Proximity Sensor
I´m trying to disable my proximity sensor in GS3. I tried with Hardware Disabler and doesn´t work, and the Elixir2 can´t disable the sensors.
Does anyone know another app to disable the proximity sensor?

Disable Proximity Sensor AOSP

Hi,
The proximity sensor on my Galaxy Note 2 has broken, which means as soon as a I make a phone call the screen goes black and I can't end the call or wake the screen up.
In touchwiz there is an option to disable the proximity sensor during calls but I'm using an AOSP rom, I have had a look in all the settings and there is nothing about disabling the proximity sensor during calls.
The sensor is called "cm36651", I have tried to disable it using Hardware Disabler but I can't find it in the list of devices even when I search from "/".
So does anyone know another method of disabling the proximity sensor?
Thanks
Go into the phone app. Click settings. Untick the turn on proximity sensor during calls.

You ever figure out how to disable that annoying thing?
I'm pretty certain that after hours of endless searching, I'm just going to unsolder it from the board... grr
During calls, does your screen turns on again if you shine the proximity sensor under a bright source of light? If yes, all you need to do is recalibrate. I had the same thing happening.

Hi, what I found works for me is to run these two commands after every reboot.
echo 0 > /sys/class/sensors/proximity_sensor/prox_cal
and
echo 1 > /sys/class/sensors/proximity_sensor/prox_cal
The 0 resets it and the 1 calibrates it, not sure what the problem is but it works for me everytime.

I tried everything I could find, including several root programs, and nothing would keep my screen from going black when I made phone calls on Nexus 5 (after broken screen replaced). Tried every single proximity sensor "fix", and disabler app but nothing worked. The Sensor kept showing 0.0 meaning it though it was right up against an object.
I finally put a piece of foil in front of the sensor, and now it reads 5.0 (max distance) and FINALLY the screen stays on in phone calls - unless I tap the power button to shut it off.
There must be some factory calibration they do with the original screen, and any replacement one is just not quite exactly the same.

Proximity Sensor does not turn off screen during calls Please Help...

After every reboot,the proximity sensor works fine for the first few calls. It properly turns off the screen during a call when the device is near your ears & turns the screen on when it is moved away.
But post 4-5 calls, the sensor stops working. Irrespective of how you hold the device, the screen does not get turned off. User needs to manually turn the screen off & on using the lock button. This continues for all calls after that.
Rebooting the device fixes this problem again but only for 4-5 calls...
Can Anyone Found The Fix???

Try an app called gravity screen. If it still does the same thing - works for a bit and then stops working - you may have to flash some stock software and start fresh or you may have a hardware issue. It could also be something simple like some dirt or dust in/around your proximity sensor that needs to be cleaned out; you'd have to be brave and open the phone to blow the debris out though. But try the gravity screen app first because it may be all you need.
And are you on stock ROM or AOSP/CM? Because AOSP/CM has always been wonky with the proximity sensor during calls.

Phone screen stays black on phone calls.

I'm not sure if it's a proximity issue, software, or related to the phone app itself but quite frequently when I'm on a phone call my screen will stay black even if I pull my face away from the phone. Pressing the power button does nothing, double pressing it for the camera shortcut will have the phone vibrate but still black screen. If I place my finger on the fingerprint scanner it vibrates but still black screen. The only way to get the screen to come back on is for the other caller to hang up. It was especially bad when I called my voicemail and couldn't hang up so it was stuck like that until I held the volume up and power buttons to manually reset the phone. Is anyone else having this issue?

run it on safemode and see if it still happens, if not then there could be an app messing with the experience.. if still doenst turn on while on call on safemode, then call support.
Are u using immersive mode?
I've read that some experienced this after an update to the phone app. I had this problem and it turned out something was wrong with the proximity sensor. I downloaded an app to test the phones sensors and it always said near for the proximity sensor. Had an RMA done on it
I am having the same issue...
Funny thing, i can wake my screen well when I'm calling with my Bluetooth device (Alpine player). But if I'm using the phone, the screen stays dead.
They should at least give us an update that would let us to wake the screen manually.
You guys need to give more detail like are you stock, rooted, modded? Something to go off of

Here is what you do... Remove your screen protector and throw it away. Then, buy one with a proper cutout for the proximity sensor.

I'm stock with no screen protector just an Incipio dual pro case. I've taken the case off and tried cleaning the phone but the still persists without the case on. I've also tried booting into safe mode and still the same problem occurs. At least now I've went into the settings and turned on power button ends call so I can hang up now. Talked with google support and sent them a bug report awaiting their response.

Yep mines saying NEAR for the proximity sensor. Guess I'm going to wait on the answer from Google support and RMA the device too. It's weird because I don't have any screen protector or anything to block the sensor and the proximity sensor was fine for the first 2 months.
