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.

No notification LED after MM update on ZE551ML?

Maybe it is just me and my device, but since the MM update (the real one, not the beta) my notification LED doesn't work. I have tested it with text messages, emails, missed calls, charger plugged into my computer, charging plugged into a standard charger, and charging plugged into the fast charger... nada on any of them.
Anyone having this issue? If so how have you rectified it? It has been a minute since I first got this thing (got it at launch) and the MM update reset all my settings so maybe there is a setting to turn it back on I am missing?
Help out a brother if you can. Thanks.

OK, so does anyone have any suggestions for an app that might help by letting me manually setup the notification LED?

Thanks for the reply. It is not in DND as far as I can tell (not on).

If you haven't already, try a factory reset first

Actually yes. After I wiped my phone for my wife the notification now works.
Another issue that I recently found the solution to... if your ZF2's proximity sensor has gotten crazy sensitive since the update try cleaning it. Seriously. Especially if you have a tempered glass screen protector. I thought the piece of advice was bogus but I cracked out my lens cleaning spray and cloth and BOOM, the proximity sensor works correctly again.

Thanks! Got the led working again after a factory reset.
By the proximity sensor do you mean the little one next to the selfie camera or the GPS?
After a lot of fixed I've got the ZF2 working fine, except for the "smartlock - safe places" that thing can never work right.

Sorry, I just realized that you had replied.
Yes, the one beside the camera. Many have had an issue where the screen goes black after you start or answer a call, especially after the update. It seems the update made the proximity sensor much more sensitive. Since all decent screen protectors have a small cutout for the proximity sensor it will tend to accumulate dirt and oil from your skin. Wiping it down doesn't seem to get it clean enough for the sensor so you have to get a little more aggressive to clear the problem up. I went months enduring the problem and even set my phone so I could disconnect from calls using the power button and then ended up stumbling over the solution when setting up the phone for my wife when I upgraded to my Axon 7.

No led indicator
Hi i've been experiencing the same issue. After I update my zenfone 2 ZE551ML 4gb/64gb version, I have noticed that the led incator is not working and it is not found in the settings. Also, another issue I have encountered is that quick charging feature is not working sometimes but sometimes it works. I don't know how to fix. I'd be glad if someone could help with a step by step process. Thanks in advance!

8.1 Update broke proximity sensor ??

hey guys, maybe someone can help with my pixel 2 XL 64 GB in Germany
Since I upgraded to 8.1 my ambient screen doesn't work properly, black screen on calls and so on. I'm pretty sure it's some change with the proximity sensor. i used some apps to test the sensor and when I clean my screen really hard everything works fine (shows "far" in the test app) but when i just wave without touching the screen, it goes to "near" and doesn't recover until i wipe the screen again ( wtf?). I can't really use the phone like this. I am in contact with Google support but they give the generic suggestions like restart the phone etc.
Everything worked fine under 8.0. i actually went ahead and flashed 8.0 back on and it works properly. it seems like they increased the sensors aggressiveness in 8.1.
For most people the problem gets resolved by taking off the screen protector but I don't have one applied. neither are there any scratches on the display. Maybe my sensor is flawed in some way :/
I also tried the turning on /off adaptive brightness trick, to which there is a thread somewhere.
maybe you guys can share your experiences or fixes,
Thanks and Liebe Grüße from Germany !

I myself had some odd behaviors after updating by using the factory image with the -w removed from the flash-all.bat and ended up starting from scratch due to my cat. (Long story) but anyway, I think you will find a few other folks had bad results of some sort or other after updating. Personally, I would back up everything with TiBu and a good nandroid. ( kill any pin or fingerprint stuff first). Get anything off the internal storage you don't want to lose also.
Worst case you have a few hours of putting it back together and best case you flash from scratch and restore your data partition in TWRP.
If you factor in the time screwing around trying to "fix" it, you might be better off starting over. Unless you did actually install 8.1 from scratch them forget all this. Lol

I did enjoy your cat story a while back! Dang varmints!

FWIW - I received the OTA update on my phone (unlocked version) and the proximity sensor seems to be screwed up. I having the same issues you've described. I've also got the mooshi ion glass screen protector on my phone.

thank you! i already did a fresh factory flash of the 8.1 firmware from the Google devs website. Didn't solve the problem though It works fine on 8.0 so I don't get it.
It's really strange that only a bunch of people experience this problem. I kinda hoped for a functioning phone , at least for 1000 bucks.
I'm considering to get a replacement if nobody finds a fix to this.

Not sure if it'll help, but I installed "Sensors test" by Ettore Zaffaroni. Mine works just fine on 8.1 stock unrooted. The version is the OTA update to DP2.
In the Proximity test, at the bottom of that is says:
Vendor: AMS TAOS
Version: 2
Max Range: 5 cm
Resolution: 1 cm
Current: 01. ma
Maybe check and see if it is the same vendor and version. And if the other numbers match. I measured it activating between 1 1/2 inches and 2 inches, pretty much only directly in front of the sensor. I have a screen protector but with a hole cut out over the sensor.

Same issue here, no screen protector installed. Tried a factory reset without luck, tried safe mode without luck. Only started since 8.1 update.

Since the 8.1 OTA, I'm having an issue where the Always on Display doesn't always stay on and when the screen goes black, I can't use double-tap to wake it back up. I have to use the power button to turn the screen back on. I wonder if it's related to the proximity issue, because it's almost as if the screen thinks you have the phone up to your ear...?

Same issue here. Downloaded Sensors test, and Proximity shows as "NEAR", I've got a screen protector covering the sensor.

I have the same issue. Pixel 2 xl, after upgrading to 8.1, proximity sensor says near when screen protector is on. I think that most likely something is messed up with the update.

Wanted to add that I have a screen protector, however had the same one on 8.0 and had no issues. Also that neither DT2W or raise to wake works when the screen goes black, only pressing the power button. The issue seems intermittent. Always On Display seems to be working about half the time, whether I allow the screen to automatically shut off after a minute or if I press the power button to shut the screen off.

yes i did the test with the app sensor test and it shows "near". I downgraded to 8.0 and it works fine.
For all of you guys with screen protectors:
try removing it, it solved the problem for some people but not for me (i didn't have one on the first place)
or try downgrading if you know how to.
I went to my carrier today and they told me they got an email from Google about the 8.1 update is kinda messed up, so i should wait for the next patch. Idk what's going on, but i hope Google is aware of this.
thanks for the replies though!

I'm also having similar problems with my phone with the sensor. Also with the gesture features not working such as, double tap and flip for camera.
Ambient display not functioning is properly the most annoying, along with black screens after phone calls.

I did notify google of this issue. It would be good if all of you spend few minutes to do the same. That will let them know it is not an isolated incident.

Removing my screen protector immediately solved the problem for me. Just ordered another one that won't cover the proximity sensor.

I don't have a screen protector and I have the same issue with my proximity sensor. Anyone figure out a fix?

No fix that I'm aware of,
but there are many more people with similar issues.

Same here, had a full glass screen protector on my 2xl (on Oreo 8.0)and I cracked it when carrying a pair on ladders, phone was in my pocket at the time. So I ordered the same screen protector again... Once again it worked fine but as soon as the update to 8.1 was installed I was getting a black screen whilst receiving a call and had to wait for the caller to hang up before my phone returned to normal. As soon as I removed the screen protector the phone was fine. I've checked this 3 times and the same thing happens. Google have done something to the proximity sensor in the last update, no question.

Same issue here, no screen protector installed. Screen goes black every time I try to use the phone while on a call.

Funny how my phone worked perfectly with my screen protector before this 8.1 update for the two months the phone as been out. Now I can't hang up phone calls or turn the screen on during phone calls. -_- Hope they fix it soon.

screen turns black on incoming call

Hello good day. When I receive a call to my redmi note 8 device, the screen turns black before I bring the phone to my ear. I wake up the device with the help of a button or fingerprint. I am getting information about the sensor setting. but it didn't work. I get a calibrated error message. previously i was using india original update now i am using xiaom.eu stabil 12. i am getting the same error. please help. thanks

I have the same problem. Try installing the latest firmware. It didn't work for me. A quick work around is to quickly cover and uncover the top portion of the phone where the proximity sensor is located (near the selfie camera). The phone screen should come back on. I really wish this would get fixed for the numerous people that have this issue.

I forgot to mention that you shouldn't have any kind of screen protector on your phone when you are trying to figure this out. I don't know about other models. I've had the exact same problem with two different RN8's. It's either a bad batch of proximity / light sensors or it's a firmware / software problem that is yet to be resolved. I have done a full search of this forum and numerous users have the same issue we do. Nobody has a fix as far as I know. Please let me know if you learn anything new.

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
