the proximity sensor not working right for me
when i take a call if i put my phone into my face the screen is off (this is ok) and if i put my phone away from my face the screen should goes back on but it is not. the screen is off for a long time until the people i call with is hang up the screen just on. some time the screen is off for a short time.
Has anyone had any issues with the proximity sensor on the Nexus doing the same thing?
please help me what should i do, now i can't hang up my phone or pick up my waiting call or adding the number etc. because the screen is off while i having a call
i have try to wipe my phone and flash my phone many times but it still the same
Strange. Try checking to see if the proximity infrared led is still flashing after it goes off. Check by starting a call and looking at your phone through a webcam. You should see the proximity light flashing. Then hold it up to your face so it goes off, then check it in the webcam again to see if the proximity light is still flashing.
There could be a hardware problem with the light not coming back on, or not being bright enough or something...
Thank you very much
so what did you do?how did you fix this becouse i have the same problem?
My only real big issue with this phone is that the proximity sensor doesn't work unless I squeeze it between my fingers. In dark lighting it's the only way to turn on the screen. Also,it's the only way to get the screen to turn back on.
I downloaded an app to test the sensor ans it says it's near even if there's nothing in front of it. But after I squeeze it the test shows that it's far
hi guys. i recently replaced my cracked screen and after that i noticed that the auto rotate function isn't working properly. some times it's ok but sometimes like when i go to camera, and when I come back to menu, the screen is Locked on landscape mode and the only think I can do is to lock the device and unlock it to make the screen portrait.and after that i cant change the screen orientation att all unless i restart the phone.
Mostly the screen has a light that only noticeable in the quite dark place when the auto screen light is on after turning off the screen.
i had some problems with ambient light sensor and proximity sensor as well.
i once wiped the data i was thinking maybe it's a software problem but nothing changed
is it really a hardware problem? is the board or any parts damaged during the replacement?!
Same problem Here
I have the same problem, but it is with ambient light sensor and the proximity switch, when i go to the service menu (*#*#7378423#*#*) the proximity switch does not show up, when i press ambient light sensor it says ¨This device does not support this function¨.
This phone i just bought it a few this ago, i tried reseting customization, wiping data, flash another rom, Root... everything and no answer.
If u wipe and flash and still have the problem it is possible you have a hardware problem. Check all of ur water damage indicators to see if they are red. Also you could tell us your model.
I got a Sony Xperia z3c d5833. Yesterday I installed an app named pocket lock. The main feature of this app is to lock the screen when you cover the proximity and light sensor. Now the problem is just when I Uninstalled this app, the proximity sensor permanently switched ON automatically. And I can't view my screen during calls. I replaced the proximity sensor kit and also re-installed the firmware and went into stock mm6.0.1 from kit kat 4.4.4. Also installed the lollipop 5.1.1
But invain and the problem is still there. My proximity sensor kit which I replaced with another Xperia z3c is working fine in that phone.
I need help....
There is a problem with the display glass on the Z3C separating from the sensor, with an always ON sensor the result. Google and you'll find it.
You can test it in the service menu. It will show as ON, and go OFF if you lightly press on the top left corner of the display.
So you might have a hardware problem. Sometimes just glue the display corner down works.
There are also a few fixes that disable the sensor. You really do not need it. It is a battery saving feature.

All was going fine and fantastic until I installed this fckn app pocket lock ? there's no need to change the proximity sensor kit now because I already have changed it and the most interesting thing is that the faulty proximity sensor kit doing fine in another Xperia z3c. To assure myself that new kit should work fine in my phone I flashed it thrice with three different ROMS but nothing worked. Now I'm wondering how a software can damaged a phones motherboard. It means there's only two things left for me to change, Bootloader and motherboard. D5833's bootloader isn't allowed to be unlocked so therfore I can't upgrade the bootloader, now the only thing left is motherboard of my phone. .
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.
No problems with Verizon S20 FE 5G UW

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.
