I am having an issue with my proximity sensor and believe it may be some sort of calibration issue. It works (ie when I am in calls, if I cover it with my finger, it shuts off the screen) but the sensitivity has become very poor. I've had the phone since the day it was released and the proximity sensor had no trouble reflecting off my head and keeping the screen off during calls. Over the last few months I've noticed I started hitting buttons with my ear during calls because the screen is not shutting down. It seems like the sensitivity has decreased by some fixed amount in the last few months. It is very annoying because I keep accidentally hanging up on people or hitting the hold call button while I am talking.
The only two things I thought it could be would be either the sensor needs to be calibrated or possibly the sensor is going bad. I'm running the cyanogen 7 nightlies but have also tried reverting to some of the more stable RCs and still had the issue. I will try going back to a t-mobile rom tonight to see if that helps.
Has anyone else experienced this? Or does anyone know how to re-calibrate the sensor?

I gave it a shot, but I didn't see anything for calibrating the proxy sensor in that app.
I did however do a test using the camera on my transformer and compared the intensity of the proxy sensor LED to that on other phones. It appears as if mine is very dim and barely blinks. I think the infrared LED is burning out or the circuit that supplies it is not putting out the correct power.
Has anyone ever tried replacing a bad proxy LED before?

That, or use one of those compressed-air cans for cleaning stuff and blow it into the speaker hole towards the proximity sensor (to the left of the speaker hole.) The proximity sensor seems very sensitive to dust particles.
You haven't installed or changed screen protectors recently, by any chance? Those have been known to mess up the sensor. Also, make sure the protector or glass is nice and clean in the area of the sensor.
Thanks for all the great advice! I'm going to give the vacuum and air can a shot.
Oh and to answer redpoint, I haven't installed any screen protectors on this phone ever, but thanks for the advice.
My GF's Vision behaves the same...
Still looking for a calibration tool, i found only one, but that don't work.
Also tried to "clean" the sensor
I think we have to return it to htc...
Same problem with my DZ since I put Virtuous G Lite on it. Did you guys find a solution for your proximity sensor ?

I am having the same problem. I keep hitting the hold button. Any fixes?
Hello
The proximity sensor doesn't seem to work on my note II anymore. Whenever i make a phone call the screen just goes black. Also direct call and quick glance won't work. Tried to do the tutorials but nothing.
Anyone else had this problem? Do you guys think it is a hardware fault or software wise? I have tried using two different custom roms and unrooted stock rom.
Sorry for the late reply, but did you ever find a solution for this? Because I just started experiencing the same problem with my phone, and I want to know if I need to try and get it exchanged. Thanks a lot.
Anyone can help ? My proximity sensor not working too ....
Using N7105 Singapore Singtel.
Did not find a solution. A guy told me to get it repaired but still havent't done it.
there is no solution for this sadly
Proximity sensor
Guys i also have the same problem....was searching for solution for quite a long time.
The problem seems to be either the sensor is damaged due to fall or there is dust on the sensor.
The solution which i got are:
1 Send to samsung gallery for sensor replacement (Safest Option and only if the sensor is broken)
2 Take a compressed air can and try blowing through the earpiece grill. (Many have got the sensor back to working since the dust blows off)
I am personally going to try the compressed air solution since my phone didn't fall. So assuming sensor is not working due to dust inside.
Hey Guys, the fingerprint sensor on my Nexus 5x (LG H791) stopped working out of the blue the other day. I bought the phone on eBay about 2 months ago, and the seller told me it had an international warranty. However, this warranty is not supported by LG Canada (so much for being international). FUrthermore, the seller says his stuff shipped from the US, but it actually shipped from Malaysia. Needless to say, I was pretty pissed off.
Anyways, the 5X has been great until the other day. I pulled the phone out of my pocket and tried to unlock it with my fingerprint as I always do. It didn't unlock, didn't vibrate, and didn't do anything. I pressed the power button and tried again. At this point I noticed the dreaded red words across hte bottom that said "Fingerprint Hardware Not Available". After a quick google I see that people have resolved this problem by rebooting the phone - which did I did, but the scanner did not come back. I then cleared the cache, and that did not solve the problem.
I then noticed, that night, that my phone was fully charged whne I went to sleep and when I woke up it was at 20%. Normally, I'll lose 3-5% overnight. I checked what was using my battery and "Phone Idle" had kept my phone awake for 14h!
SO - I've tried removing a bunch of apps, booting in safe mode, playing with the security settings, display timeout, and a bunch of crap - nothing has worked. I have NOT formatted/recovered the phone yet (I'm out at a mining camp and this is the only way I keep in touch with my girl. Also I forgot my USB-C to USB-A cable.)
What do you guys think - did the fingerprint scanner just crap out? I would really like to get it working again, cause I love(d) this phone. I upgraded from a Nexus 4 and I was a big fan of the nexus, until this crappity crap happened.
Anyways, thanks for your help in advance with figuring out these two issues.

EDIT - the original title for this post was "[ISSUES] Fingerprint Hardware Not Available - and now Nexus Imprint is missing..." I have since changed the title to reflect both the finger print and the camera trouble shooting, results, and further questions.
Bump - can anyone help???
Guess there isn't anyone here that's knowledgeable enough to help me with this issue..
Well, I tried removing a bunch of apps, to see if something was causing it - it was not. Then my camera stopped working.. Sometimes when I'd open it up my camera would work, and sometimes it would just crash. I've since performed a factory reset on the phone and there is still no option for Nexus imprint. Whenever I try to open the camera the screen goes black, shows the camera icon and then the Camera app just crashes.
I've got a replacement fingerprint sensor which I'm going to install this weekend. I'll keep you guys in the loop, because apparently this is something that no one here can help with.
Got the fingerprint sensor replaced on my phone. When pulling out the old one there was no visible damage. The connection was solid. I installed a new sensor (which I purchased for $16 shipped to my door I'm Canada from esourceparts). After turning the phone on, in my security settings, "Nexus Imprint" appeared. Set up the new fingerprints, and it works flawlessly.
Looks like it was hardware not software.
The camera still doesn't work, battery life has increased remarkably.
Happy again.

Can't agree with you more (I also upgraded from Nexus 4, and a nexus fan).
I have the exact same issue right now.
It happened to me right after the Nougat upgrade, so I thought it had to do with it, so I tried everything, including downgrade back to Marshmallow, but nothing works.
It's exactly like you wrote, suddenly the fingerprint stopped working, showed this red "hardware" message, then it disappeared completely from the settings, and also the phone started to drain battery twice faster. It's probably has to do with the fingerprint sensor, maybe it's trying to detect it all the time or something, draining the battery.
I'm really frustrated, we're going on a long vacation in 2 weeks and I really need the phone to work well... If I'll order the sensor from ebay right now, it won't get here on time
I think this was my last nexus... (had nexus S, nexus 4, and nexus 5X)
update:
just received OTA update (build NRD90R) which seems to fixed the fingerprint sensor, it works again. hope it will stay this way, don't wanna jinx it.
My fingerprint sensor also seems to have bitten the dust. It sporadically ceased functioning whenever I got it slightly wet, either from sweat when running or if exposed to a little rain. It would always come back after a few hours, however this time it seems to have completely quit. I have done a factory reset and it is still missing. I'm fairly certain I have an issue with the hardware. My phone is under LG's warranty since I bought it from Amazon, so getting the sensor repaired will mean weeks without my phone. It sounds like people are having good luck with replacing the fingerprint sensor themselves. Is this difficult to do? I'd much rather take this route if I can.
I got the "fingerprint hardware not available" message last night out of the blue. Tried a few things to no avail.... Flashed factory image and it works good as new again.

I went ahead and bought the parts to replace my fingerprint scanner hardware myself. Not 2 hours after I place the order, my fingerprint scanner just randomly starts working again...after 3 weeks. Bizarre. Regardless, I'm planning on holding onto the backup hardware just in case.

No I have not.
But that's a good idea. I did a factory reset on the phone and that didn't solve it. After a restart I can open both the rear and front facing cameras without a problem. But after about 3 minutes of the phone being on, some bug happens and I cannot open the camera. I get a black screen and either I can kill the app and continue using the phone, or the phone just restarts. When I get the black screen I cannot switch to the front camera either - the phone just craps out.
I'll try loading the factory images and see if that helps.
So I fixed the problem by taking apart the phone and installing a new fingerprint sensor.
Google Play support, Google Support, and LG Support would not extend service to this phone because it was an international version. Unfortunately, Google support couldnèt do anything other than to tell me to try a hard reset (which I did).
I ordered a new fingerprint sensor from epartsource (Canadian supplier) which cost me $16cad shipped to my door. Taking apart the 5x by following the instructions on ifixit was very painless. It was incredibly easy to replace the sensor as well. Before putting the phone back together we booted the phone up, and went to the security settings - low and behold, nexus imprint was an option again.
The old fingerprint sensor did not appear to have any damage, the clip was firmly in place before we removed it, and the unit looked like it was in good condition.
This has also solved my battery life woes; I can get about 4 days on airplane mode now.
Now, all I need to do is fix the camera (I lost use of the camera about 4 days after the fingerprint sensor crapped out.) I have since ordered a replacement camera from Aliexpress - I'll post up a new thread for that when it comes.
I'm not sure why the fingerprint sensor AND the camera would both stop working at or around the same time. I think that something may have impacted the rear of the phone causing damage to both of them. Very poor if the fingerprint sensor is THAT fragile.
I'm happy to have my phone working near 100% again. I am a very loyal nexus customer, however, that is changing quickly with the lack of service provided by both Google and LG. Google, I hope you're listening. You need to do more to keep your customers.

The more I thought about it, the more I think it has to do with water. If your finger is slightly wet, DO NOT use your fingerprint sensor. I'm fairly certain it was this that killed mine. Or a slight impact to the back of the phone.
Regardless, I treat my stuff pretty well and I take good care of it. I was at work, however, and I need to spray down things so my hands are constantly wet. I had been using my fingerprint sensor with damp/wet fingers in the few days before it crapped out.

I like to use my phone with an armband while running and my armband has a "clever" design with an open spot to give you access to the sensor. Unfortunately this means it is in direct contact with my skin and sweat while I run. I got in the habit of sticking a small cloth between the sensor and my skin to keep it dry, but apparently even tiny amounts of moisture on your finger when it's raining seems to be enough to damage it. Anyone know if this is just an issue with the 5X sensor or do other phones also have this problem?

It makes sense... The sensor is probably some sort of heat detector that can discern slight differences in heat on the surface of the sensor. A ridge of your fingerprint would conduct more heat to the sensor than heat that's radiated to the sensor from a fingerprint valley. It probably makes a quick map of the thermal Imprint and matches this to your saved profiles.
Or I'm out to lunch. Lol.
However, I'm pretty sure water killed mine, and the fingerprint sensors are very fragile. I've stopped using mine all together until I have clean hands. This means no using it at work.
Bought a replacement camera module from Aliexpress and finally got around to installing it. With the cover, and the frame off, new camera module installed, I was able to open the camera, use both the front and the back cameras.
However, when I closed it all up and went to use the camera, I get the same errors. Black screen, cannot connect to camera, and then it crashes/restarts the phone.
Definitely not hardware!

I downgraded from N-Preview 5 (? v.7.1.1) to android 7. Camera would only work for a few moments after immediately rebooting the phone.
Sideloaded 6.0.1 using fastboot and unlocked bootloader - the first time I ran the new install, the camera app crashed instantly. Rebooted, and now it's been working fine.................. Let's see how long it lasts! Will update tomorrow.
So. I followed the instructions on Google's page (https://developers.google.com/android/nexus/images) and I sideloaded build MMB29V. And the camera NOW WORKS! I left the phone powered on over night and the camera will start anytime I need it to. I installed all of the available OTA updates, bringing me up to NBD90W, and my camera is STILL launching flawlessly!
In other words - a fresh factory install fixed the camera issues!+
Edit: Just sideloaded in the latest version of 7.0.0 (NBD90W, Oct 2016) and the camera is stable. The stock android camera is version 4.1.006.125161292. I will keep you updated as it progresses. The actual camera module in my phone is the one that I ordered from Aliexpress ( https://www.aliexpress.com/item/Ori...era-Module-Replacement-Parts/32657390368.html) The black housing on the camera module was a bit different than the OEM one I pulled out. I didn't check any serial numbers to verify; so I don't know if the one from Ali is actually OEM.

That's encouraging! Mine died overnight, after being intermittent yesterday. Went onto eBay and ordered a replacement from Asia for about CAD$9 delivered, should arrive around Christmas.
esourceparts (I'm also in Canada) only had the black sensors -- mine is white, and I like white.

Hi, everyone. So I have an LG G4 for more than a year now and I am very pleased with its performance. I did have an issue with sometimes the audio is stuck after a call but I think it more has to do with bad reception as I noticed so its rare this days. However, lately something happened with the knock on feature which I cannot figure out at all. Sometimes it just doesn't work. I tap and nothing happens. The power on button is working perfectly but the knock on is unresponsive. I fiddled with the proximity sensor but it's not it. Sometimes it just stops working for 5-6 times and then it works and the again it doesn't. There is no pattern. When it's powering on the feature works with no hiccups but after that it's like the cpu forgets to monitor the process. I don't know. I have tried calibration and it works with no problem for a few minutes and then it goes back again to this stutter. Does anyone have any ideas about this? I am thinking factory reset but the hassle would be pointless if the problem persists and I am in no mood to install all those apps I have from the beginning for no reason. Any hep will be really appreciated. Thanks in advance.
I am experiencing the same issue but mine Knock on is a bit delaying.. for an example, I double tap on the screen and it gives response in 3-4 mins or not... I am suspecting from screen protector which has been mounted for almost a year, it could be corrupted(scratch) Give a try on removing the screen protector(if you have any)
It's a hardware problem. Many threads online about it

Is your case or temp glass protect over prox sensor. That can affect it bad. Also scratches on glass over prox sensor. If not. Then more than likely hardware related.
No the screen protector does not cover the prox sensor. It's cut out as it should be. I am starting to think it's a hardware problem. The thing is why now?!

No. I haven't touched it at all yet. I am pretty satisfied with the performance so I left it alone. The only thing worth mentioning is that I overheated taking a lot of pictures during an event. Maybe this did a number on it!
I have been discussing the issue with a technican today. It is a hardware issue, you cannot fix it. Apparently, the proximity sensor dies after ~2 years - at least somewhat. Why somewhat?
Check this out: You can check the status of your sensor using MINIOS, type *#546368#*815# (n.b. - swap 815 for your model number).
Now click device test - MT - ok - Individual Item - Sensor test - WAIT!
The proximity sensor will run a test and likely come up with a figure between 60~90. The actual value should be 220+.
Meaning: Your phone thinks it´s ~6-9 cm away from your face, that is not enough to trigger knock-on but it´s far enough to be triggered using the backside button.
My knock on doesn't work, but knock off does. Not a major issue, just annoying!
So i have an H812 model and last year i had the dreaded boot loop issue but got it fixed under warranty and no issue since with that. The issue that is irritating the hell out of me now is that the double tap to turn screen on just stopped working reliably. It barely ever works.
I've tried the sensor calibration from the hidden menu and i have a question about that also. My sensor acts like it calibrates fine but the # next it seems kinda low (# next to proximety cal pass ...). It's around 48. See screenshot for reference taken from xda https://forum.xda-developers.com/attachment.php?attachmentid=3513220&d=1445359160
Has my sensor just crapped out? and if so, is that normal. Any help would be appreciated, i've gotten so addicted to using that feature that people ask me what the hell i'm doing when i try to turn their phones screen on lol.
Edit: No screen protector on btw and the internal board as far as i can see seems fine too. And the double tap to turn screen off works fine.
Thanks

Is the little black rubber plug in the prox sensor. They may have forgot to put it back in. This little black plug is required for proper prox sensor to function properly.
Thnaks for the response but It worked perfectly for quite some time after the board was replaced by the service center so don't think that's it.

So i opened it up and checked the rubber piece just to make sure and it's there. Everything else looks ok. I guess the sensor just crapped out and will just continue to live with it.
