proximity sensor not working?

Hi All,
My proximity sensor isn't triggering during calls (Possilbly at all?) causing me to accidentally put people on hold.
(very annoying! at least make a tone so I know I hit the button)
Is there a switch for that?
What's weird is that I don't see a HW test for the proximity sensor in the diagnostics screen (tapping on kernel version)
Edit -> settings -> system apps -> phone -> incoming call settings -> proximity sensor is ON.
Can someone whose proximity sensor is working download a sensors test app like https://play.google.com/store/apps/details?id=com.wered.sensorsmultitool&hl=en
and tell me if that detects your proximity sensor distance correctly? (or whatever app you want, just tell me which one).
- Frank

Go to Settings - About phone and tap 5 times on Kernel tab. You will get into test menu. There you can to test and calibrate proximity sensor.

I don't see it. What is the test called?
What Rom are you running? I'm on 8.0.10.0

See pictures below. Test menu works on any firmware.

Just looked at mine and I have prox sensor as number 9. Sounds like you may need to flash an updated build.

I updated to developer rom and proximity appeared and was working.
I then re-updated to stable rom (8.0.12.0 i.e latest) and it dissapeared again!

You already have the answer you're looking for. Guess the sensor is broken in the stable build. In this case, you may have to wait for the next stable release or use an alternate ROM.

Confirm proximity sensor missing in 8.0.12.0
Unfortunately, it is also missing in 8.2.1.0 stable

On Chinese 8.2.3.0 and the settings are missing from the CIT list also ... with that said I don't depend on it anyways lol. Just checking things.

for some thick case the proximity sensors might have problem... need to reboot phone with case on to "register" the case thickness...

hi mi mix fans , I came through lot of applications,proximity sensor tests, procedures, secret codes etc . to get solution for "screen off during call and not on automatically" but i found the real solution in this is .. remove back cover which almost users use . , tpu transparent also and see whether it work during call ..yes,finally got solution. check yourself all test works properly and screen on during call when device is away from ear..if not ?? pls consider to clean sensor ..

Wanted to test it. I can see the test, but not sure how to test it. I still don't.
So I tried to the front microphone test to learn how to use these tests...
But it scared the s**! out of me. It's such a haunting noise! Is that normal?!

I'm on global stable, CIT proximity option doesn't show too. I think my sensor is bugged by my cover since when the device isn't covered the sensor works fine.

Yes, such an annoying noise.

i have same problem i just updated phone after proximity sensor not work why xiaomi not try before update this f*cking fw.

What I observed is after resetting when I tested it I came to know that sensors sensi
What I observed is after resetting when I tested it I came to know that sensors sensitivity distance increase up to an inch but starts dropping again as I move object in front of sensor 8 to 10 times and is reduce to 1 cm finally which is very less if you hold mobile in left hand ear but it works on right hand ear as proximity sensor is placed left of mobiles front side.I think it is a software problem which xiaomi should look in to.Sensor keeps on calibrating till it reduces distance to 1cm from nearly 1 inch that is 3 cms.This is very shameful for xiaomi that after so many years of experience they have not yet resolved this for Mi A1.

My proximity sensor also isn't working. I've tried to do this test we find on kernel tab, but I couldn't test it, it shows no options for me to calibrate or sth. Help me please!!

Same issue here. Phone just turns black, when I am calling people - difficulties to restart the display afterwards. Using Lineageos 16 - no chance to tab the kernel there. Dialing * # * # 64663 # * # * shows no results. Wandering, if this is a hardware or a software issue.

Note8 Sensors error - Any of you faced with?

I have Note8. It has a very strange sensors error, as below:
- All sensors, from proximity sensor, light sensor, to GPS, iris scanner, and all the other sensors do not work at all.
- In the app like Phone INFO Samsung, CPU-Z or AIDA64, in the Sensors section, all sensors do not work.
- The Auto Brightness function does not work (due to the light sensor), the brightness of the AOD screen is also not adjustable.
- When making a phone call and move the phone close to the ear, the screen does not turn off due to proximity sensor.
- Auto Rotation function is not working (due to rotation sensor).
- Google Maps shows inaccurate location. Other apps that rely on GPS (such as the speedometer app) are completely not working.
- The iris scanner function does not work either.
It was about two weeks ago. I've Wiped the cache, restart the phone but does not make sense.
Yesterday it suddenly returned to normal, I don't know why.
But today - while I'm typing this post - all sensors suddenly do not work again.
Any idea about the error and how to fix it?
Thank you guys

Best advice I can think of is to factory reset and see if that alleviates the problem.

If you did not do anything firmware-related, or you did not drop or submeged your device, the best you can do is to make a warranty claim, pure and simple, if you have no way to make such claim, well, next time you should consider getting a device from an official source

I've read other users have had same problem. Ones I read said it was motherboard issue had to have sammy replace it.

Thank you guys

There is also built-in sensor test. Open dialer and dial *#0*#

I noticed a problem when I was playing Asphalt (racing game on me Note 8). I am unable to use the Tilt controls to move the scar.
Testing out the Sensors using *#0*# at the dialer revealed that all the SENSORS was faulty.
I reset the whole phone just now. The issue is still there with the sensor. As expected Auto rotation doesn't work.
Running the latest version 8.0.
I recently changed my motherboard (under warranty) 3 months back cos something was faulty. Seems it may be another motherboard issue.
Anyone else in this thread solved the issue?

Hey everyone I'm facing the same problem. All sensors stoped working but they were working before on 7.1.1 and i updated my device to oreo and realized all sensors stoped
Then i got another updated for about 900mb i thought maybe this update will fix them and also that update said tha after updating the user cannot downgrade to nougat but after updating the problem still exsist. Please if anyone can help i also try to flash same oreo firmware with odin but doesn't fixed the sensors

Proximity sensor doesn't work in call. Autobrightness sensor also glitch.

Currently using PixelExperience Plus ROM. Was using HavocOS before this. There were similar issues in both the roms.. The proximity sensor just won't work during calls. Phone needs a restart to fix this.. goes back to problematic in a short while..
The autobrightness sensor issue is less frustrating.. waking up the device the brightness gets stuck at about 50%. The slider does nothing.. locking the screen and waking up again solves it. Minor issue..
But.. does anyone have a fix?

Same problem here with latest oficial rom. Randomly screen goes black in a call although the phone is on a table.

Same problem here

Why do Xiaomi seem to have such a problem with proximity sensors?
The one on my Note 7 doesn't work properly and a google search reveals complaints about sensors on many models.
It's not as if they are rocket science any more.

Could this also be the reason when I receive a call the phone screen on some occasions didn't even light up and I have to double tap to see who's calling. I really hope it's something they can fix.

Did anyone get a fix? I still have this goddamn problem! Even with the latest evolution x rom or pixel experience rom (tried the latest version released like days back for both roms). This problem started right after I unlocked my bootloader and flashed a custom ROM and the problem is present in EVERY custom rom that I've tried. Please help me out with a fix as this is really annoying and the phone is practically useless. As soon as I make a call or get a call my display simply shuts down and doesn't switch on until 30 secs after the call ends. So my display is basically off for easy 2-3 minutes. Can't use my phone then. This sucks when I've dialled a wrong number or want to cut the call myself because I can't do any of that!

[MAYBE FIXED] Proximity sensor on Redmi Note 7

Hello everyone,
A few days ago I installed the V11.0.4.0.PFGMIXM firmware and no longer face the Proximity problem anymore.
Just download and flash newest Firmware You can download it at here: https://xiaomifirmwareupdater.com/firmware/lavender/

perfect, thanks for sharing, excuse me, after doing this do you know if it also solves the GPS location problems?

I don't meet any problem with GPS location before and after flash this firmware.

I just started experiencing a proximity sensor issue on MIUI 11, EU version 11.0.4.0
It occurred a few times after longer phone calls (more than 10 mins) when I removed the phone from my face, the screen would not light up. Neither the lock button nor the fingerprint sensor would wake it up, and I had to wait for the other person to hang up. Or maybe it only reacted to the lock button after 5 seconds or so.
I don't remember this happening previously. Is this something you guys have experienced?

I faced same problem and i never paid attention to it. Now and I'm reading your post, i come to realize that the redmi-note-7 has a sensor problem and i have a miui 11.0.4.0 global version

I have heard about other people having proximity sensor issues on earlier versions of MIUI, also different editions (China, Global, EU). I've even advised some of them to re-calibrate the sensor through the service menu. I've been using the phone for 9 months now, I believe. I've updated it regularly and never reset it to factory settings. If this keeps up, I'll try re-calibration. If it doesn't disappear with the calibration or the next MIUI update, only then I'll consider factory reset

Hello
How I have Redmi Note 9 Pro MIUI 11.0.4.0, how can I turn off the proximity sensor? I have the screen problem other people are mentioning above

After a year i finally fixed the proximity sensor problem in the OnePlus 7 Pro

so in short this problem has plagued the phone since day one and i suspected a HW issue since nothing fixed it. for those who dont know whats im talking about, you are lucky. the issue is basically that the proximity sensor is missed up so the screen will light up when you are in a call or listening to Whatsapp/Telegram voice messages.
The Solution:
The problem, turned out, was caused by the factory screen protector that came already applied to the phone. i removed it after it was damaged and also removed the case (Spigen Rugged Armor Case), cleaned the phone and VIOLA its working perfectly fine now...
i hope it works for everyone else.

So, what you are saying is:
Since when this phone got launched in May 2019, not a single user facing the proximity sensor issue had the ingenious idea to remove their factory applied screen protector and you are the first one to come up with this "fix"?
I am really sorry to be this discouraging but: This ain't it chief.
Good that it fixed your perception of the issue though

Comrade, the issue is far graver than that. OnePlus 7Pro does not have a proximity sensor per se. It uses software (an ai I think) to "guess" whether to turn on the screen or not which is why listening to voice notes gets crazy...

Even though it does have an infrared sensor under the screen (that has been proven), i agree with you that it seems to be using something like that.. Curiously, the proximity sensor once fired when i flicked off my lights in my room.. This indeed leads me to believe there is more going on than just a simple infrared proximity sensor..
But yeah, i don't think removing the stock screen protector "fixes" the thing.. It may improve things but i doubt it's a fix.. As i said, this phone has been out for a while and people would have noticed if removing the screen protector fixes the proximity sensor for good..So yeah, cheers mate.

I took the screen protector off before I turned the phone on for the first time. I still get the screen lighting up while I'm on a call, often muting it with my cheek.

I must be lucky but at the moment I have no such issue with my new OP7P (MFD: 2019/05). RR Rom. Still have the screen protector on it. What's the MFD of your unit ?

i have problem with my oneplus since i rooted this phone
after root i have installed pixel expereince rom
when i called i found proximity sensor not working
now almost 6 months no fixed i'm stock oos
please help me there is no guard on my phone also no cover

The simplest solution for me has been to use a Bluetooth headset. I rarely use it without it.
