Hello,
I recently replaced the front frame of my Lumia 820 due to dropping it. While the touch screen now works, I'm having issues with the proximity sensor in regards to calls, where it turns the screen black and doesn't come back on when taking my face away from the screen.
I took it all apart again, used compressed air to blow any dust away and made sure nothing was blocking the sensor.
Is there
a. any way to disable the proximity sensor?
b. does it anything to do with the Amber update? (works fine prior to this)
c. is there a way to go back to an older version of the firmware?
Thanks in advance!
Hi,
I have same problem. Anyone find solution to that? Probably proximity sensor need to be calibrated, but I didnt find any site with software and information how to do it.
Brg,
Pawel
I have the same issue
I'm having the same problem. I replaced the touch screen and the frame.
Alon.
Same issue
I am experiencing the same fault as what you guys are describing. I've even ordered from other sources to see if it was a faulty batch of screens, but still blank in call. Is there something in the fitting process that is going wrong? Any update or Fix would be great!

My friend had the exact same issue after replacing the screen. He finally took it to his local Nokia Care centre, they noticed straight away that the replacement screen wasn't a genuine Nokia part, fitted a Nokia one & he's never had a problem since.
simply make a call and try pressing the left side of the earpiece

just make a call and when the display goes black, simply press the left side of the earpiece, then you can see the display. its the problem with the new touchpanel. tigtly fix the touchpad to the panel and you can get it working. not a big issue. i too faced the issue and noticed the solution accidently. hopes it ill be usefull to you guys

Hi. I have been tightening keepeng pressing on top left... Simply took it off digitizer have cleaned to clear proximity glass on digitizer. Cutted very small peace of business card and glued it in between sensors gap on actual sensor and assembled back. Works fine

Hey man, I'm having problems with the same issue but can't seem to work out what you mean with gluing the business card in between the sensor gap? Also in my case I have to push quite hard on both sides before the proximity sensor works, even after tightening it all the way.
Hey. Disassemble your phone. On digitiser a designated hole for proximity sensor. I have cleaned that tint place and made it clear. Now look on proximity sensor. Its rectangular shape and has 2 lenses on it. In between , a very tiny space. In my case i took business card, as it thick, then i have cut very small piece of business card and glued it in that place. Give me you email, so i send you a picture

most of china digitizers work ok but many of them have got extra not cutted plastic in upper left corner (see picture)
this extra plastic makes bigger space between digitizer and frame that's why proximity sensor "think" it's covered.
There is no hope to make it work without cutting such plastic. Unfortunately this cut must be exactly "in line" with line from digitizer operation lines so it's almost impossible to make. China manufacture must make new type of digitizer with thinner digitizer lines and always cut such extra plastic. Then digitizer will be exactly flat on frame and proximity sensor will be close to his hole in digitizer and will work 100%.
Proximity sensor solution: request for clarification...

Hi,
How did you remove the color coating to the lens? And do you think that made a difference? Or was it the extra pressure the tiny strip of card put on the sensor?
Thanks,

Hey guys, I'm having same problem ... can you send the picture how to solve this issue ... [email protected]

Hi I have bought an LG G2 D802 from eBay for practically nothing. The only thing that was wrong with it is that the screen had been replaced by what I presume is a cheap Chinese copy and after the replacement the screen would seem to turn off randomly (particularly during calls) and could not easily be turned back on again. Otherwise the phone works fine. The only thing that doesn't work is the proximity sensor. However I presume that this is a result of the new screen. Having read around on several forums, it seems that the proximity sensor is extremely sensitive to things like screen protectors, which can obstruct, or limit or prevent the functionality of the proximity sensor entirely. I therefore concluded that the likely issue was because the proximity sensor is likely to only respond to light over a given number of polarities (dark infra-red, placed against face, something similar I presume, in daylight or bright light, nearer the blue end of the spectrum etc). This would simplify how the proximity sensor should work under a number of given scenarios.
In the end the workaround was simple. I simply opened the phone and disconnected the proximity sensor and placed a small piece of insulating tape over the sensors connectors so it couldn't inadvertently reconnected when I closed the phone. The phone is now 100% fully functional, minus the proximity sensor of course. It now just functions like any other normal smartphone. I am naturally more than pleased with this outcome, given what I paid for the phone, which itself is in otherwise mint condition.
However the question I have is that the reason the proximity sensor was included was to prevent accidental button presses when making or receiving a call, when for example the phone is pressed against one's face. However it strikes me that exactly the same functionality should be possible in software? What I am looking for then is an app that will either lock the screen (or turn it off) to prevent accidental button presses in this way while a call is in progress and that will disable itself as soon as a call is ended. I of course need to be able to easily disable it, either from the lock screen, or via the power button, so that for example when I dial an automated dialling service and they want me to press buttons to navigate their menu I can still do this.
There seems to be a few apps around that can do this, but my question is, which is the best? Which is likely to cause the fewest problems for what I want?
I have ordered a new proximity sensor from China in case the proximity sensor itself might be at fault, but really having read that this can cause several problems and is rather more 'gimmicky' than practical, I think a software solution would probably be better anyway.
it should be replace with same hardware sir to be able for your device able to control it.
So has anyone found a fix for this problem aside from replacing the sensor itself? Maybe a build.prop or by using terminal. My phone screen wont stay on because it detects its in my pocket all the time posted screens below of useful info.

If you don't have the patience to read my story, skip to the solution at the end
Guys (and girls)!, I have found the solution, it took me like 6 hours to figure this out.
I have LS980 (LG G2 ofcourse).
I replaced the screen, and I actually refurbished the screen with LOCA glue myself, it is perfect, but apparently there's an issue with the proximity sensor, due to the specific shade they use to cover the inside of the glass at the location of the proximity sensor.
After replacing the screen, the Knock ON was not working, but KNOCK OFF was working fine.
In the Sensor Box i saw that i was getting half of the light that i was supposed to (on another LS980 i was getting about 800, while on the "faulty" one i was getting 400 light.)
And also the proximity sensor was dead, it showed 0.0 and a fallen plant.
I tried putting some tape, and colored it with a permanent market between the proximity sensor and the glass, and the KNOCK ON began to work, but during calls, the screen would not shut off.
I figured, there must be some SYNC between the light the screen is getting, and the proximity sensor, so i scraped off the paint that was on the glass where the proximity sensor is, so there will be much light coming in, and IT WORKED!!
SOLUTION:
Scrape off the dark paint on the glass (inside) at the location of the proximity sensor. do it gently.
clean it with alcohol so there will be no remains of paint.
don't be shy to press the Thanks button if this worked
Thank you work great

I just got my screen replaced, and this is happening to me. Is this something I can do myself?
My Fix
I apologize for bad english. If anyone knows SERBIAN and want to translate beter contact me.
Before you start to scrach the touch, try this.
On LG D-802 , the ruber thing on the proximity sensor was cousing me promblems. CUT the ruber only the part atached on the light sensor and proximity and turn it around. The big hole that was once on the light sensor(Ruber) comes on the proximity...
And that fixed my proximity. Now the light sensor is covered with the small hole on the ruber and the small amount of light is passing try that hole, try spreading it with heated something.
If questions PM me.
I think I am having the same problems with a G2. The digitizer on my girlfriend's phone broke so I replaced it with a digitizer/screen combo. No we can only turn the screen on (power button or knock) when there is a lot of light in the room. If it is dark, the screen will turn on for a second and then turn off. The screen doesn't go dark during a call either.
This problem didn't start until I installed the new screen. I scraped half the paint off but it didn't seem to make a different. I also don't have the screen completely sealed as I didn't have tape pre-cut for the shape of the phone. I wouldn't think that makes a difference but who knows.
Since I am a newbie in this technology, what is a proximity sensor and what is it used for when it detects or does not detect something?.. I installed the proximity sensor finder app on my Nexus 6 and I could not tell any details except timer started when portion of phone front was covered YET the measurement displayed did not say anything other than 0 or 5.00000 etc.. I also use the phone in speaker mode ..
The proximity sensor is there to turn the screen off during a phone call when you move the phone to your head. It turns the screen back on when you move it away from your head after. On the 6P it is located below the speaker grill.
Thank you,, so the proximity sensor serves a power saving function? I just tested this with my Nexus 6 using a TruShield TGSP and it worked fine.. I find it strange that a clear glass screen protector would not work on the Nexus 6P ??

No, the purpose of it is to deactivate the screen when it's against your face on a call so that you don't press things on the screen with your ear/face.
Yes, it does save a little power (you can power off the screen while on a call), but is really helps the screen know when you have the phone to your face. This allows it to disable input so you don't hit buttons on the screen while on a call.
It's a neat feature, but adds some difficulty because not all screen protectors are cut out to allow it to function fully. Like those above said, it helps you by not pressing buttons while you're talking.
I would also assume that android uses the proximity sensor for "on body detection" to tell if it's in your pocket or out in the open etc.
I am having similar sort of issue, I have glass protector on nexus 6P and when I dial any number the screen will go black and will not come back until the other person hangs up. even the phone is not near my face, how strange. not sure how to resolve
I also have a problem of my screen not turning on if I move it away from my face. At first I thought it was proximity sensor dead, but I used the proximity sensor finder app and was able to see that it works fine if I cover it. So it could be a bug with dialer/caller app in Marshmallow. Or maybe there's a setting somewhere.
How to turn off the proximity sensor? I have a tgsp that does not have a cut out for the sensor.
Return the tgsp because it's defective. The newer revisions do not suffer from the defect.

My screen does not go dark when I put my 6P by my ear. How can I check if my sensor is on or off? TThanks
Just picked up the 8T and am using it on a Folio case. What I noticed is that closing or opening the cover does not trigger the screen to turn on or off. Question is should it be? Let me say that I believe the proximity sensor is working as the screen does turn on and off during a call when I move the phone near my ear. Just not sure why it won't work in general. Curious if I have a defective unit
Not all cases are made equal.
some are made without respect to sensors.
which sounds like the case you have
Hi there,
I have a Google Pixel 6a with a replacement screen. All fine so far except for the proximity sensor (screen will not turn off/on during phone calls). I opened the phone again and noticed that the proximity sensor is actually working! But as soon as the screen is above the proximity sensor, it stops working. It seems the sensor is not "seeing" through the screen. But all is looking good to me - exactly as in different screen replacement tutorial videos on youtube. The replacement screen looks 100% like the original one. The screen was replaced by a phone-repair-shop - so I think they know what they are doing. I contacted them when I noticed that the sensor does not work anymore. But the phone came back to me again with the same error.
Do you have any ideas how i get the sensor to "see through the display"?
Regards
As i know the proximity sensor area on the replacement screen is clean and free from any dust, fingerprints, or smudges. Use a soft cloth or microfiber cloth to gently clean the area around the sensor or Sometimes, a slight misalignment can cause the sensor to be obstructed. Try repositioning the screen carefully and see if it makes a difference.
