and Knock-On won't work.
Fell from about 4 feet onto a rubbery floor (gym service) while working out. Have an incipio feather light case on it and there now seems to be a small dent above the ear speaker. No idea why knock-on stopped, knock-off is fine everything else seems normal

You probably broke your proximity sensor. If that's covered knock on won't work to avoid starting the phone in your pants.

That is what i first thought because initially after the drop the screen would turn off right after being turned on. After a few restarts that seemed to have gone away but still no knock-on. I downloaded an app call "Phone Tester" and the proximity sensor comes up as "near"
Neare means blocked
its possible that your connector is just disconnected. if you can open up the battery cover and the rear cover its quite easy to find the connector just give it a press and see if it works. tip for opening the battery cover - pull the micro usb side!!

Got it (you'd think they could just say blocked).
So I kind of smacked it around, cleaned it off etc etc and it says "Far" now. Knock-On is sporadically working.
I may try and take apart the back cover and poke around

i tried to search the forum with no results btw
have two cases while receiving/calling with hd2
1. via bluetooth headset - even when the phone is in the pocket some apps starts randomly, even call is disconnected - isn't proximity should cause phone scrren to be blank all time?
2. via the phone - sometimes while talking screen is still dark and pressing eg. home key puts display on. sometimes moving phone away from ear turns screen on.
do you have some or its something with my phone?
I have the same problem, the proximity sensor does not work, I think it works only outside when you have strong light, try it and let me know.
make a call the screen will go off now move it from your face loking up at the sun outside you will see that the screen will turn on.
it works only when I makes a call. when I am getting a call it atays on.

Well you would be wrong then.
It's a proximity sensor, not a light sensor. I just made a call in my darkened room and the proximity sensor functioned flawlessly.
thake the screen protector out or cut it and the proximity sensor will work perfect.

Wow who would've thought that covering up a sensor designed to sense when objects are close to it would impede its functionality.
Your revelation hepled me fix the microphone on my phone. It wasn't working, and then I realized I had my hand over it!
Yes I have had issues even with the original HTC screen protector which has two small holes directly over the sensors. I finally had to remove it.
Cutting the protector I have not been very successful so far. This creates sharp edges and the protector tends to peel off from that point. For the time being I am relying on the fact that the screen on the HD2 is scratch resistant enough that with normal care it would not get scratched. With over 2 months of use without a protector my screen is still scratchless.
IF it is anything to do with the screen protector, then there are plenty out there that don't have this effect.
I've got a protector on my HD2 and have had it there since just after I got it, so just over 2 months now. The screen protector has worked perfectly, even, kochavy, in the dark, because it detects proximity not light.
I suggest removing any screen protectors and seeing if you still have the problem. If you do, send the phone back as faulty. If you don't, get a better screen protector.

do you have the original HTC screen protector with the two holes? there are some protector that does not cover the top of the phone and leave the two sensors out from protection.

No I don't. The one that came with it never please me much, so I bought some better ones.
The protectors I have don't have any holes for the sensors at the top, but like I said, it just works perfectly. There's a lot more to this issue that just the screen protector, as some people have reported that it works perfectly when they ring certain number, but not when they ring others. From what I've read on other threads, this is commonplace for people who are having this problem, so it's obviously not an issue with their screen protectors. It sounds like a software issue to me, but since it can't be identified as such, they should just return their phones as faulty and hope the replacement doesn't have the same issue.
It would be interesting to know if the people with the described issue have upgraded the ROM to 1.66, as this seems to have fixed a whole slew of issues.
Sensor works by reflecting infrared light. There is small IR lamp with IR detector nearby. You can check that by looking at the sensor through some digital camera or camcorder, whose are usually sensitive to this light. Don't forget the phone must be in call, otherwise the sensor is turned off.
I think the sensor itself is OK. But there seems to be some relationship with guess what .. G-sensor ! Once I found the screen just won't go off during call, and it was when I was lying during the call, and I was holding the phone upside down portrait style.
But as I turned the phone to normal position (normal portrait) and back, it started to work with no problem.
I only had problem with proximity sensor once since then .. but rotating the phone up and down helped again.
I think this needs more investigation .. if you encounter the problem try this.
Hi,
Lately i have been noticing that the proximity sensor on calls on my s5 is not working properly. Once i answer/make a call, when i place the phone in my ear it shuts down the screen but the problem is when i take it away from my ear, the screen doesn't turn back on.
I tried the the testing menus (*#0*# or something like that) and when i placed my finger close to the sensor it detected, going green and vibrating but it doesn't go away from that state.
The only thing that changed was that i applied a glass screen protector a few days ago and im thinking it could be that, but its strange because its only when i back away from the screen that it doesn't register, so i don't know if that or not. Also, the protector is properly aligned and the edges are not on top of the sensor.
Anyone experienced this on their s5?

You have to change the proximity sensor or cancel it(cutting the flat)
I ended up removing the screen protector and it went back to working properly =/ I can't really put it back on now because it attracted specks of dust and it doesn't glue well now =/
Cutting it flat means it deactivate it? Because i find it useful for phone calls

Hi,
I've recently changed the LCD panel on my Nexus 4, as well as the headphone jack (which includes the proximity sensor) - the screen was broken, and the headphone jack had very noisy output.
After putting it back together, I noticed that the proximity sensor wasn't working - during calls, it would constantly blank out the screen, and there was no way to unblank it (i.e. it seems to permanently think there's something there).
I took it apart again and noticed that the rubber gasket that fits behind the sensor is missing - it must have come off during the repair and gotten lost.
I tried putting some Blu-Tack behind it as a temporary fix, but no change. Now, I'm not so sure the new proximity sensor is working either.
Anyhow, my first question is, where can I buy a replacement rubber gasket? I've done a search online, and I can't seem to find it for sale anywhere?
Is it available as part of another spare part for the Nexus 4?
Cheers,
Victor
I had to replace the screen on my n4 too and fixing the proximity sensor was a pain in the ass. I had the rubber gasket but it was only working when the front panel was not attached as soon as i attached the front panel it stops working i.e. when in call the screen goes off but it doesn't come back on. So what the guy did was to scratch off the two holes on the top left from the inside of the panel. its looks a bit nasty but its working fine now. you might wana try to scratch off a bit neatly. like in a round shape.
I dont know if the gasket is the cause, but I know a case where this exact problem happens : its when u don't push the sensor well enough to fit in its place, cuz it should be near enough, or it'd blank the screen during calls. Try using a flat screw driver, and push the orange part where the sensors are well enough, that should do the work ( don't push haaard or I'll Damage it). I hope that'd help, cuz finding this gasket is hard. And this applies also for the guy who commented, cuz this is the case for him

Hey guys,
just yesterday I got my phone back from repair (I cracked my screen, nothing was working then).
Here is a photo of my old screen, which had a hole right below the upper loud speaker:
I think it might be that the drop broke the sensor, and not the repair itself?!?
Using an app like this: https://play.google.com/store/apps/details?id=com.tigermonster.proxfinder shows that my sensor is constantly detecting something.
I'm not using any screen protectors or anything
For now I rooted my device and disabled the sensor by installing the xposed framework and then using http://repo.xposed.info/module/com.mrchandler.disableprox
Strangely enough, yesterday, like 3h after I got my phone back I called someone and everything, including the sensor was working perfectly!
Can anyone show me a picture of such a proximity sensor? Do you guys think a fix like in this video shown: https://www.youtube.com/watch?v=HPHsianYnqo, putting a piece of paper behind the proximity sensor could work?
You never ended up showing any images of the phone before/after the repair but if you have a screen protector fitted to the screen and it doesn't have a little cutout on the right just below the top speaker then the protector is constantly tripping the proximity sensor.
Thanks for your answer. Like I said, I am not using any screen protectors.
Here's an image of my old screen:
http://imgur.com/ufNSseD
I don't think it has anything to do with that damage now tbh, because it was working well yesterday. I guess maybe the connector loosened itself?
Which one here in the pictures to step 6 is the proximity sensor? https://de.ifixit.com/Teardown/Nexus+6P+Teardown/51660

Thanks for the info about the position of the sensor - I'll definitely do that when I'm going to disassemble my phone (which is gonna take a while since I'm waiting to receive a new rear housing from a seller in the US).
I'm planning to disassemble as little as possible, so I'm hoping it's easy to access the proximity sensor (but guessing by the pictures it should be).

Good luck. Hope you can fix it by cleaning it. Make sure to have some thermal compound on hand to replace the old stuff when you disassemble.
Hey one more quick question:
Do you think it's possible to remove the motherboard without removing the battery?
I guess that the problem is that the proximity sensor is either too close to the screen, or too far away (like there's some small gap between the proximity sensor and the screen). I will probably have to remove the motherboard if it's the former (if it's the latter I can just put something like a pice of paper at the back of the rubber).

You won't need to remove the battery to remove the main board. You'll just have to unplug it.
Alright, thanks. I am wondering about another thing: Why are there two holes for the light and proximity sensor on the backside of the phone? I was planning to try and first stick some piece of paper on top of that rubber plastic to get the sensor closer to the screen. Why the holes?

I don't know which type of proximity sensor this is, IR, led, electromagnetic etc. But all proximity sensors I know of have two "eyes" One eye emits ir, led, or electromagnetic field, the other eye looks for a change in the return field. I think you'll find a scratched, smashed return eye. Or debris lodged in the sensor housing. Use a magnifying glass and excellent lighting.
If you shine a bright flashlight at the sensor through the screen can you see anything blocking the eyes? Doesn't matter I guess, you'd have to disassemble to get it out of the way anyways.

It looks like the prox sensor comes covered in a rubber cover. In this pic the rubber is there:

In this pic they removed the rubber to expose the prox sensor:
https://d3nevzfk7ii3be.cloudfront.net/igi/eDldW3bJmHSbQEYF.huge
I suspect the rubber could be missing, lost during repair. Or perhaps installed wrong.

I did what you asked: There is no light coming out on the back of the phone if that's what you meant.
Anyway, I'll have to wait until I receive my replacement back housing and then I'll try my best to repair the sensor. I hope the rubber is just misaligned.
Alright - so I did have time today to disassemble my phone (got the replacement housing last week).
I noticed that there was no rubber part on top of the light and proximity sensor, as well as on the device above the two (i don't know what that is).
What I did is that I had a small tube like this one: https://sc01.alicdn.com/kf/HTB1hBgwKVXXXXcvXpXXq6xXFXXXY/8mm-small-clear-plastic-PC-pipe-TUBE.jpg which I painted black and put it on top of the approximity sensor.
Everything is working well again (there were some lints on the display right below where the proximity sensor is located, that's probably why it stopped working from one day to another).
I guess the main function of the rubber is to protect the sensor against dust and lints.
I also am very mad at myself for having forgotten to take out the NFC antenna from the old housing before replacing it, so I had to open my phone again after I did already close it (and now there are slight traces of an opening - again )
But apart from that everything's fine now and I hope it'll stay this way.

Glad you got it fixed! And yeah, unfortunately it's nearly impossible to remove the back cover without leaving dings at the injection site. When I put on my new top and bottom rear covers I removed most of the glue. So next time I can remove them without much trouble.
I am having similar problems. I just traded for a nexus 6P and everything works great except for the proximity sensor. The 6p was just OTAed to 7.0 and I only unlocked it and installed TWRP. No other changes and no root (yet).
There is no screen protector on the device.
When I make a call, the screen stays on. The screen turns off as soon as I cover the proximity sensor. The screen then does not come back on until the call is completed. I downloaded a bunch of proximity apps, including Proximity Sensor Finder. Proximity Sensor Finder (and others) report that sensor detects Far (5cm or more) and Near (value of 0 cm when the sensor is covered). The sensor doesn't seem to identify intermiate values. The odd thing is that the sensor doesn't seem to reset. If I cover the sensor (value of 0 cm) and remove my hand, the sensor continues to read 0 cm.
Does this sound like a hardware or software issue? The device appears to detect both the near and far states, but doesn't return to far after the sensor is uncovered. Thanks for any help.
Solved the problem. I downgraded to MM and the proximity sensor problem persisted, so I figured it was a hardware issue.
I took apart the 6P and the there were signs that repair had been performed. The screen was probably replaced previously. The little rubber gasket covering the proximity sensor was missing, just as the OP described. I cut a blue-colored straw and placed it over the proximity/light sensor. Works perfect!
I need to bump this thread cause a few days ago I started having the same problem that nickfuzz describes.
Now I've got my opened phone in front of me and tried putting a pice of a black straw around the two sensors, but that does not help. It reports 5.0 cm and if I cover the sensor it stays at 0.0 cm
Can anyone give me an advice about what to do now?
Update:
The light sensor is also not working properly: It is reporting way too less lightness, and tends to report 0 lux when I'm not directly holding the phone under a lamp (for instance).
After 5 hours of trying I somehow managed to at least get the sensor to always report 5.0 cm. That's better than constantly reporting 0.0 cm.
I put a piece of a wide straw (there are different sizes, you know) around the hole board on which the two sensors (light & proximity) sit on. I guess this is a bad idea.
I am now trying to get this rubber gasket from somewhere, but I guess I'll have bad luck since I'd have to buy a defective nexus 6p from which I could take it from
UPDATE:
Can anyone tell me why the screen is painted black on the inside, right where the proximity sensor is located? I scraped off the paint and painted it over with a black pen. That must be the reason why the proximity sensor is always reporting 5.0 cm (which doesn't make much sense, because at some point it would have to detect something if it's not broken).

Can you tell me if you put the straw around both sensors and their "chassis" (that black thing they sit on), or did you put the straw only around the sensors (i.e. on top of the chassis)?
I still need to find a way to fix my sensors
I tried to use some electric tape and put it on top of the sensors with two small circles cut in, but eventually I figured that the problem actually lies in the black paint on the inside of the screen.
I removed that paint a few weeks ago and I couldn't paint a new black paint on it that is not too thick, so I am stuck with a sensor consequently reporting 5cm.
I did try to use an Edding.
I had the same issue with the proximity sensory and a new 6P, but fixed it with this: https://play.google.com/store/apps/details?id=com.mobiledirection.proximitysensorreset&hl=en
Everything was still good after uninstalling that app too.
I just replaced my cracked LG V20 screen and fame and while moving parts over I ripped a very small part that I don't know how to find! It was at the very top of the frame and looked like a very small and sticky cable of some sort. I think it said "4v" on it and it wrapped from the back of the frame, around the top, and to the front. It ends up right above the speaker. Since I broke this part my phone doesn't wake up to my fingerprint without me first pushing the lock button and lighting the screen up. I have been trying to look for a parts breakdown and can't find it anywhere and nowhere that sells v20 parts has been of help either. Thanks for any help!

the gray bit that says a model like f800l or vzw and then further on a digit and a letter? Cant find anything else looking at my screen frame that fits your description even a little. If so it just seems to come on the whole screen+frame assembly.

It was up at the very tip top of the frame by the speaker. I just barely put my phone back together again (literally and now checking the forum) and the fingerprint sensor seems to be working again like normal. So it could have just been a loose connection that I tightened back up or something unrelated to what I was talking about.

Yeah probabily, I know the connector for the fingerprint sensor is a bit touchy, took a couple times opening and adjusting things for a good connection (it totally disappeared from lineageos settings when it wasnt connected right. I hope you didnt forget to transfer over the tiny rubber piece for the proximity sensor (right next to the front facing camera), I missed that first go around and when on a call the screen was forced off until the other party hung up)
