Proximity sensor seems to not work anymore

I first noticed it when the screen didn't black out during a call. Then I downloaded an app which checks if there is a proximity sensor and the distance it reports. According to the app, the last distance reported is 5 centimeters and it doesn't change at all when I obstruct the sensor. That makes me pretty sure that it stopped working. What can I do now?

If its anything like mine, you'll start getting some even weirder behavior. When I would answer a phone call (or place one), the proximity sensor wouldn't work and the phone would reboot itself within 5-10 seconds.
I downloaded an app called "Hardware Disabler" which allows you to disable the proximity sensor on the Gnex (its the one labeled 4-0044). It works for me...only annoyance is having to turn my screen off/on during phone calls manually. But, its better than having no phone (i.e. soft reboots).
Anyway, to answer your question, i'm not sure there's much you can do (other than disable). I've read that the proximity sensors on these GNex's are a little buggy.

My Nexus Reboot During Call once in day too !
maybe my reboot problem is Proximity sensor ?
change my simcard and factory reset not solve my problem .

I have had this issue. Do you use a ROM with the active display feature? A lot of ROMs have been including this lately. I feel like my issue started when they added that. It has a "Pocket Mode" option that uses the proximity sensor and I've always felt like it messed up my proximity sensor during calls. I never had reboots but the screen would flicker on and off during a call. Sometimes just staying on. I have turned Active display off all together and sometimes it will work right and sometimes it will flicker. But for me, it seems to have started when ROMs started including that feature.

I'm just gonna go ahead an suggest the obvious, flash another ROM. Even stock if you aren't running it just to get collective results, this way you can eliminate the ROM factor.

It sometimes does it for me too, but it's very very rare. Sometimes the phone just freezes during a call (when swipe to take the call).

Can't speak for others, but I tried everything that could be tried. Flashed different Roms, kernels, and even went back to stock using the images provided by Google. Nothing fixed it until I realized it was a hardware issue. I haven't had a single problem since disabling that sensor.
EDIT: also, to clarify, it wasn't an intermittent problem for me. I could NEVER make/receive calls until I disabled that sensor.

How to disable proximity sensor in rooted phone?

So it appears that my proximity sensor is faulty because of which it always thinks there is something close to it. Due to this issue, whenever I make a phone call the screen is always off as the proximity sensor thinks my ear is close to the phone, even when I remove the phone from my face.
This is quite annoying obviously and I was wondering if I can somehow disable the sensor. I rooted the phone with the hope of doing so. I am guessing I can delete/rename an appropriate file in the "sys" folder or add something to the build.prop to disable the proximity sensor. Can someone tell me what needs to be changed?

Use an app for disabling/mocking sensor reading, e.g. this one. I'm using it on Nexus 5, which after some time stops reading data from proximity and light sensors. Unfortunately, for this one you have to install Xposed too.
Maybe somebody will come up with an app, which will work without Xposed.

I know I could do it with Xposed but Xposed does not work for Nougat. I need a solution for Android 7.1.1.

Disable proximity sensor

Hi,
My girlfriend's Nexus proximity senor seems to be broken and her screen is black all the time when she's calling someone.
Is there an easy way (root or not, I don't care) to easily disable the sensor all the time or in Caller app ?
She's on latest stock Oreo 8.1.
Thank you

Experiencing this as well. From what I have read, it is an issue with 8.1 specifically and the 5X.
Google haven't really acknowledged the problem yet, which sucks.
Related reddit thread
For calls, pressing the power button twice seems to bring the screen back for use again - doing this too quickly starts the camera, if you have that enabled.
This probably won't help for other use cases, like whatsapp.

I can understand that it's a bug for WhatsApp (she has that bug too), but for the dialer too ?

I don't experience such issues. My prox sensor is working like it should. Though I have a friend who has some minor problems with it, but he has a glass screen protector on top of it. Mine has a cutout for the sensors

My old original Nexus 5 had this problem and I got around it with an Xposed Module called Disable Proximity Sensor. That module has since evolved to something called Sensor Disabler (Link: https://forum.xda-developers.com/xposed/modules/mod-disable-proximity-t2798887). It doesn't say that it has been tested on the Nexus 5x, but it might still work. I am not sure how compatible it is with the new Oreo version of Xposed. Installing Xposed might be a bit overkill, but if it fixes the problem, it might be worth it.
I know how frustrating and annoying a busted proximity sensor can be, so I hope you can find a solution.

Proximity sensor bug

After the update I'm having trouble with the proximity sensor. It stops suddenly. Usually when I put the smartphone in the pocket. It was perfect before 172 firmware. Anybody notice anything? Any tips? I have the EVRL29. I also made a factory reset.

Hey, you can use the APP that comes with your phone to check if the proximity sensor fails.
How to open it: HiCare-Service-Smart diagnosis-Auto
Good luck

Thanks, But everything's fine with the sensor as Hicare. I don't believe it's a hardware problem, but I don't know what I can do about the system.

Do you have a black screen when you are talking?

When the sensor is locked, no. Sometimes the screen turns black immediately when I get the phone call. That is, the sensor is locked. Passing the finger over the sensor a few times, it unlocks and goes back to work.

Having the same issue. I thought it was because of Drupe (am using it instead of default dialer). Weirdly, proximity sensor activates even before attending the call sometimes and am not able to do anything. Just let the call ring it out and then have to call back as even locking/unlocking doesnt work.

have upgraded to version 184 and the problem continues. I don't know what to do. Disappointment with Huawei

Are you using full cover tempered glass screen protector?

Unfortunately I'm not ?

I don't know if it is updated firmware bug or hardware failure. My friend's phone has this problem too, and even worse when dialing or listening to voice SMS in FB messenger, the screen was off until the voice finished. I thought it was full cover screen protector; however, it was not after I suggested him to take off the screen protector, and the problem still persisted. Anyway he told me there was not any problem before updating.

Are you using full cover tempered glass screen protector?In addition, can you check whether the position of your sensor is clean.

I'm not, and it's clean. It works until I put it in my pocket, then it gets stuck.

Today I realized one thing, if I touch the screen where the sensor is for more than 2 seconds, it hangs. If I stay near, it works ?

My friend just sold his mate 20x with proximity sensor error and bought a new one with the same firmware version 9.0.0.184. The new one worked functionally with its proximity sensor. I think that his previous mate 20x had proximity sensor hardware's problem, not dead but not functional.

Ich have the same issue with a P30 Pro New Edition. I hope it's a hardware issue and the replacement unit will be fine.

Proximity sensor

I have seen some reviews about the issue of proximity sensor and turning on the screen during calls ,
Did Xiaomi solve it ?
or
I want to ask if this issue is severe .
sorry for my bad english
thanks in advance

I didn't have any issue with proximity sensor, others say they did... Sincerely i think that they're just holding phone against their head wrong while talking...

Issue exist. Wife and son have problems with screen turning on and off. I watch them while talking. Without any movement of cell phone or head, screen turns on. So, calinorg, you are wrong.

Hi, you can try to calibrate the sensor by tapping several times on kernel version in Settings and see if it works.
Good luck,

I think I've heard somewhere that there is a slight problem with the proximity sensor but that was due to it being ultrasonic rather than infrared. I'm not sure but may be that might be the reason.

hi all,
I have a Mi 10T, Indian version(MIUI Global 12.0.5.0 Stable). I have faced this issue from time to time too.
I did something that helped, I cleaned the LED indicator light hole and ear piece opening, using a bubble gum(please watch a few youtube videos on how to do that and do not get any residue of gum stuck in). Then as said above calibrated the sensor from kernel version settings.
Before the clean up, 6/10 calls I faced this nagging issue. Post clean up, its like 1/10 calls , and mostly that one call is usually whatsapp voice call this happens with and not the google phone app.
hope this helps you guys too.
EDIT : P.S. Are people with stock MIUI dailer/phone and messaging app facing this issue too? Kindly mention your phone's ROM version, I am planning to Install Indonesia version of stock MIUI Rom for my device, to get back Stock MIUI Dialer/Phone and messaging app.
Also, I kind of have a feeling that Google phone and messaging app are not optimised for MIUI ROM and/or this device.

It has nothing to do with Google phone app, sensor is ultrasonic and it is a bit iffy from time to time...

Him I have the very same issue.
Let's admit, Xiaomi note 8 pro is ****.
I've proximity issues and headphone connector issues.
The phone price is great, the quality is not there. Simply it's a big nightmare .
What a big disappoinment.

The issue exists for sure. What a piece of garbage is this phone. :-(

at home the problem appears when I switch the screen to 120hz and disappears at 60hz, it is the 120hz mode that causes concern the infrared sensor does not follow
