I need help with identifying the problem why my proximity sensor isnt working. This gets annoying because my phone turns the screen off when making a call and you can turn it back on since it thinks something is all the time in front of it. Is it maybe dust? On which side is the sensor located? Is there any software update for a proximity sensor?
If I type in *#*#0588#*#* that runs the proximity sensor test. The screeen goes green, vibrates and stays on 1 all the time( doesnt flick between 1 and 0 if I i move it). What can I do?
I've got a problem with mine aswell. It is always 0 in the test (it can't sense if i put anything over it).
It use to work but suddenly sort of died. I'm not sure what the problem is too but I would like a fix if anyone can come up with one
Funny thing though, my proximity sensor worked fine for 1 call this afternoon, but failed again soon after. :/
Looks like this is one big riddle for the samsung galaxy users. :/
I made a discovery.. If i shone a bright light on my sensor and held it really close to it (like 0.5-1cm away) then the proximity sensor would react and say something is covering it. Only works with a bright light though :/
How bright is that light? May I ask you what are the other 3 values of your sensors?

hmm it was the flash from my digital camera. I think any decent light would work. Try a torch, if that doesn't work try something a bit brighter.
As for the values, which 3 values do u mean?? sorry
Light, magnetic, accelerometer.
Which rom do you have?

oh, the values for accelerometer work fine, the xyz values react as they should when i move the phone.
Light sensor goes as high as 15000 lux when I shine the light on it.
Magnet sensor: 2 and the xyz change and react as they should. same with Azimuth Pitch and Roll.
As for the rom, I'm on darky's 10.1 Extreme Edition
As I thought my light sensor is also faulty. It goes only from 0-22lux
My solution

I don't know if this helps, I had a similar problem.. After i made a call my screen would not auto turn back on for me to disconnect the call.
It may have been coincidence, but after i disconnected "Increase volume in pocket", everything started working properly again.

Sorry, I should had given this information. This happened on a S4 (I9505) android version 4.2.2.
I don't know if this particular phone has the same menus has mine, but its how i solved my problem.
Having this issue too.
Nothing mentioned so far has worked for me.
Galaxy S4 SCH-I545 on VZW running 4.2.2.
Unfortunately I don't know when it started so I can't pinpoint any apps as possible triggers. However I have tried out all sorts of apps status bar apps, active notifications apps, launchers (Apex is my current now)
I have replaced the lcd/digitizer on my htc sensation xl and my proximity sensor has stopped working. Every time i make calls it goes to a black screen and sometimes the battery needs to be removed just to get it to turn back on. i was wondering if there was a way to disable the sensor through the software? or completely replace it?
anyone??

i don't have any idea about the proximity sensor ,but the same thing happened to me ,when i make a call my screen shuttdown and it comes black ,i tried diffrent roms but nothing changed so i decieded to sale the phone .
i posed a post about that and dont receive any proposition or help ,with you ,we are tree presons suffuring from this bug .
i didn't sale the phone yet but before that i will taste one last possibility who is to flash my phone with Ruu ,until that time i wish you a good luck and if i found something which fix it i will post it here .
i once had the issue with screen protector on, but once i took it off, it worked fine.
definitely gotta be the screen's problem, it has nothing to do with softwares.
maybe you can try this app to disable the prox sensor http://www.androidzoom.com/android_applications/tools/proximity-screen-off_pjwz_download.html
if the app works for u, rmb not to touch the screen when u are making a call.

ok ,i will try this app and i will see if the phone respond positively .
I have a HTC Sensation XL and have also found the same issue when replacing the screen, both the speaker and Proximity sensor stopped working. After looking around for a while i found the comments on this site from a guy that obviously has come across the issue often:
psytechrepairs.tumblr.com/page/6
It sounds like a common occurrence that they fail with a screen replacement. I've also found that the light sensor and proximity sensor seem to both be on the same removable replaceable board (some sell it as a light sensor & others sell as a proximity sensor but they are both together):
www parts4repair.com/htc-sensation-xl-sensor-light/
Hope this helps.
I know this is an old thread however I have found a solution which i would like to share.
When replacing the lcd the way to fix the proximity sensor is to cover BOTH parts of the proximity sensor with Scotch tape and color the Scotch tape with a black Sharpie felt-tip pen.
works 100%
Hi,
sorry for posting here after so much time, but I have a problem. I smashed my display and ordered myselve a new one. Once I have changed it, the phone looked like everything is working just fine. Than I noticed that my Google Play Store is crashing, and a few apps were on my phone that I have deleted months ago.
My phone is ROOTED!!!
I decided to flash it again, the problem with crashing Play Store was solved.
After I realized my phone is acting crazy,first when I call someone the display goes black, and I cannot hang up or something. It looks like the proximity sensor failure. And even worse, sometimes the phone acts just like someone was using it, it writes opens apps, just like when someone is using the phone.
Any ideas???
Hi Guyz,
My friend dropped his nexus one on the floor and from then on he is facing a weird problem. When he receives a call, when the sensor is turned on, the screen never comes back and it remains black. The only option is to pull out the battery and i suppose the drop has made proximity sensor faulty. He is not a rooted user. Is there any menthod to disable proximity sensor without rooting ? If not how can i fix it after rooting ? Any build.prop changes ?
Thanks,
karthik

hey Karthikus , I know this is not a new post, I would like to know if you solved your friends's problem, I have exactly the same, I used a couple of apps to disable the proximity sensor but still no luck, by the way I have the cyanogen mod 7 in my nexus now. the phone is a beauty, but its kinda annoying to have to remove the battery after a few calls, also I'm using a bluetooth headset, wich kinda minimizes the problem, but still not happy. please let me know , or not, I'm planning to build a disable sensors app myself in case I can't fixit. oh, and I tried all the other solutions I could find in google, like cleaning the sensors, (I dismantled the phone already) and enabling other ways to bring the screen up using other methods like trackball press or menu press. no way, still there. so please let me know. if still relevant.
thank you.
I am having an issue where always on display is staying ON while in pocket/faced down on the table. Feels like the proximity sensor is not working while on the AOD.
Plus, the proximity sensor doesn't seem to work while in the pocket either. The setting 'prevent accidental touches' has been enabled, however it is still responding to 'double tap to wake' while in the pocket for whatever reason...
Is there any fix to this?
I noticed the AOD stays on in my pocket as well. I thought maybe it was by design that way, even though it makes no sense.
Have not had a single pocket wakeup though.
It does seem that the proximity sensor (which is really the camera) doesn't work especially well though, from reports of people noticing it on phone calls. Hopefully something that can be fixed in software.

Thanks mate, appreciate your feedback. Proximity sensor works fine on my phone during calls. Can't think of any reason why Samsung would intend it this way...
Proximity sensor issue here as well
I have the same problem. I put phone into test mode and it was bad compared to my wife's s9 search proximity sensor s20fe on YouTube and see others with issue
There is no fix. This is apparently the way AOD works now. I can't remember if it started with the S10s or S20s.

I did some research on s20fe proximity sensor, because I desperately wanted flip case to open and close the screen.
Here is what I have noticed: there are two "proximity sensors" both sides of the front camera. These sensors close the screen during call if you touch them (I'm not sure if it's enough to touch just 1 or do you have to touch both of them). You need to touch these with your cheek or finger cause they need a electric field.
Phone also utilizes front camera light sensor during call: if there is no light, it turns off the screen but for this to happen phone needs to be on up right position. Screen won't close if the phone is on desk and you cover the camera.
So anyways, my point is that the proximity sensor is not able to detect if your phone is in the pocket or not. Only way for the phone to detect this is with the front camera light sensor, and I guess this would increase the battery consumption so much, there is no point.
You can test your "proximity sensors" by typing *#0*# in dialer numpad, select sensors and touch from the side of the front camera. If the screen turns green sensors are working.

I just purchased the Samsung S20 FE 5G UW (how about we shorten this to FE UW?) with all updates AND a glass screen protector and have no touch/proximity issues.
FYI I bought it at the Costco kiosk for a few dollars less per month, no activation charges and a 90 day return policy.
the Galaxy S20 FE (5G) has no physiscal proximity sensor.
Insted it uses a combination of the front camera, touch screen and gyroscope.
I have tested the proximity issues, luckily for me there were ok...turn green. The only thing that drive me crazy is the touch screen issues which never been fixed even after updates. Oh well at least its better than before.

Mate great information here, really appreciate this.
Tested the Proximity sensor using *#0*#, I agree with your analysis. The proximity must be using electric reaction to detect if my ears are touching it or not. Covering it with a book does not trigger a proximity sensor... This explain why my screen keeps waking up in the pocket.
As much as this is annoying, there appears to be no way out Just have to let the phone face outside rather than my legs.
I also have the same issue, while on a phone call, the phone's screen goes on and off constantly and I can see the notification bar moving. Very annoying.
This is a terrible design by Samsung. The punch hole usually goes in the "Empty" part of the ear, so the screen stays mostly on.
I might just return the phone because of this issue, I don't see it getting fixed by a software update.
I have the exact opposite issue with the proximity sensor on my Samsung S20 plus running Android 10 - i.e. it works well by turning the screen off when my ear/cheek/face is very close to the proximity sensor during phone calls; whereas, when the phone's screen is locked and turned off, the proximity sensor is turned off as well. Control by hardware? Software/firmware? Don't know?! To turn the screen on without using the Power hardware button, I had to enable the "Double Tap" feature in Settings.
On earlier/other Android mobile devices - Samsung included - the proximity sensor is always on - whether the screen is on, off, or currently locked. When it's always on, you can be innovative and build a widget, for instance, to turn the screen on by "waving" your hand above the proximity sensor to interrupt the laser. I suspect new(er) Samsung mobile devices like S20 and Note20 variants might be using a "virtual" proximity sensor setup/combo for controlling the device's screen - and that really sucks!
To test if the proximity sensor is always activated on Samsung S20 and Note20 variants, I type *#77692# - which displayed a hardware screen to test proximity and light sensors. Note: if you type *#0*#, the proximity and light sensor options are absent from the hardware test screen.
Has anyone found any method - via codes even - to permanently turn on the proximity sensor, even when the screen is locked and turned off?
I searched through AOSP framework vanilla codes and couldn't see anything out of the ordinary regarding control of the proximity sensor. Samsung might be doing something dubious with their firmwares/hardwares though - well, at least, the S20 and Note20 variants are having issues with the proximity sensor setup.
P.S: Not sure if you guys are aware, but Samsung mobile devices with odd designation tends to be more problematic than their even-designated counterparts, like screen's burn-ins/shadows on Samsung S3 devices, light sensor fluctuation (which affects screen brightness control) on Samsung S5s, and now proximity problems with the S20s and Note20. Samsung S20 variants are in fact "S11" variants renamed. So the trend continues with Samsung always stuffing up their odd-designated device releases.
I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).
But couldnt find it

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.

Yes it has one. It's near the light sensor... They are both under the display.

I dont think it has .
Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7
