Hello ,
Well i opened my Iphone 12 and tried to fix the Cameras (because it has a black dot while trying to get a picture) and unfortunatly i closed the LCD and forgot to screw the Metal thing over the camera flex . So i tried to reopen the LCD again and when i pulled the screen all cables were cut
On iPhone 12 LCD there are 3 cables . 2 for the LCD and 1 for the Proximity Sensor and the Ear Speaker.
When i tried to put a spare LCD and power up the Phone , the Apple logo appears for 2 seconds and then dissapears and i have a black screen , but the phone is still open , because the sounds and vibration works fine . The thing here is that i havent a proximity sensor to connect because its also cut .
So the question here is :
Does the phone works without proximity sensor ? Or i have to put a new spare proximity sensor flex to check if the new LCD works fine ?
Is the proximity sensor the reason i have black screen ? Or i damaged the phone ?
Thanks in advance ,

It was the Proximity Sensor ... I bought a spare part from the internet and used soldering iron for the speaker .
Works perfect without face id .
I see that you already worked on getting the thing done.
This happened because as the Proximity Sensor was damaged, the phone could not detect it, so the brightness is leveled at minimum or none. Samething happens when you turn the phone on while the flex Proximity Sensor cable is disconnected.

I have replaced the lcd/digitizer on my htc sensation xl and my proximity sensor has stopped working. Every time i make calls it goes to a black screen and sometimes the battery needs to be removed just to get it to turn back on. i was wondering if there was a way to disable the sensor through the software? or completely replace it?
anyone??

i don't have any idea about the proximity sensor ,but the same thing happened to me ,when i make a call my screen shuttdown and it comes black ,i tried diffrent roms but nothing changed so i decieded to sale the phone .
i posed a post about that and dont receive any proposition or help ,with you ,we are tree presons suffuring from this bug .
i didn't sale the phone yet but before that i will taste one last possibility who is to flash my phone with Ruu ,until that time i wish you a good luck and if i found something which fix it i will post it here .
i once had the issue with screen protector on, but once i took it off, it worked fine.
definitely gotta be the screen's problem, it has nothing to do with softwares.
maybe you can try this app to disable the prox sensor http://www.androidzoom.com/android_applications/tools/proximity-screen-off_pjwz_download.html
if the app works for u, rmb not to touch the screen when u are making a call.

ok ,i will try this app and i will see if the phone respond positively .
I have a HTC Sensation XL and have also found the same issue when replacing the screen, both the speaker and Proximity sensor stopped working. After looking around for a while i found the comments on this site from a guy that obviously has come across the issue often:
psytechrepairs.tumblr.com/page/6
It sounds like a common occurrence that they fail with a screen replacement. I've also found that the light sensor and proximity sensor seem to both be on the same removable replaceable board (some sell it as a light sensor & others sell as a proximity sensor but they are both together):
www parts4repair.com/htc-sensation-xl-sensor-light/
Hope this helps.
I know this is an old thread however I have found a solution which i would like to share.
When replacing the lcd the way to fix the proximity sensor is to cover BOTH parts of the proximity sensor with Scotch tape and color the Scotch tape with a black Sharpie felt-tip pen.
works 100%
Hi,
sorry for posting here after so much time, but I have a problem. I smashed my display and ordered myselve a new one. Once I have changed it, the phone looked like everything is working just fine. Than I noticed that my Google Play Store is crashing, and a few apps were on my phone that I have deleted months ago.
My phone is ROOTED!!!
I decided to flash it again, the problem with crashing Play Store was solved.
After I realized my phone is acting crazy,first when I call someone the display goes black, and I cannot hang up or something. It looks like the proximity sensor failure. And even worse, sometimes the phone acts just like someone was using it, it writes opens apps, just like when someone is using the phone.
Any ideas???
Hi all,
I noticed that my proximity sensor isn't functioning. In fact when I call the screen remains active even if I put my hand over the sensor. I used CM10 so I reflashed stock GB ROM and it still does the same. If I use the *#0588# test I always get "Proximity: 1" value. It seems like my proximity sensor isn't working but my light sensor does. What could be the problem here?
I also tried cleaning the screen, lifting the protective plastic but no way, it still doesn't work. Also I dismounted the Galaxy S, tried to blow some air with a compressor, tried to clean the inner surface but no luck...
same thing here

I've buyed a new one but nothing changes, do you have my same problem? Proximity sensor stuck at 5.0 cm?
my search does not turn the screen turns off, How do I close a proximity sensor?
I'm also having some troubles with the proximity sensor. It works randomly (specially in the dark) and sometimes after calling or VOIPing I have to flick the phone or turn off/on the screen to be able to hang up.
Is there an option to tweak the sensitivity of the sensor?

Hi All,
I am using Nokia 7 plus for past 2 years. Andorid 10 with Nov security patch. Recently, my proximity sensor stopped working and I am not able to use phone any more (due to black screen during calls). I even root my phone and installed edxposed framework for disabling proximity sensor but no luck. Even sensor disabler not working for me. Any suggestions would be much helpful as I want to use this phone badly
I have same problem (stop working after lcd replace), try more solution, but at end i find one "working"... In Developer options enable QuckSettingsDeveloperTiles/SensorOff, this add Sensor tile to top pulldown QuckSettings menu, before call must you manually enable it, after call disable (because sensor off disable all sensors and also camera ;-)

Yeah, I have been using it. Problematic when attending calls in Skype which wont work unless you switch again. Thanks anyway
In my experience, proximity sensors don't stop working, they just work all the time! Often there's a small rubber gasket which separates the UV LED from the sensor. Can be lost when replacing a screen - I did this myself on a Moto G. Screen would go black in a call and couldn't be unlocked. I found the gasket on the floor, replaced it and this fixed the problem. Replaced the screen on a Nokia 7 Plus recently, same problem. I couldn't find a missing gasket this time, but glued a small piece of rubber between sensor and LED and this fixed the issue. Had to experiment with the size of the rubber piece to get it working properly. I think some of the UV light bounces off the back of the screen and is picked up by the sensor , if this piece is missing. My $0.02 worth...
Guys, I am frustrated with proximity sensor of my Nokia 7 Plus, as soon as I call, screen goes black.
I could stop it by enabling Developer Mode and disabling sensors, but this disables all sensors not proximity, and my camera stopped working.
Can I just remove it from mother board? any way to disable only proximity sensor?
Thanks in advance.

If you've had the screen replaced, I think the rubber gasket separating the IR LED and sensor has been lost. Seems to be a common cause of this kind of problem. Cheers

Yes, I replaced screen. I don't remember about rubber gasket, but now i have to open scree and fix it.
Can we just remove proximity sensor from board? What functions get affected?

I guess just the screen turning off during a call. But removing it may damage some other component, I guess. I also wonder if the screen stays off or on permanently if the sensor is removed. If you're taking the screen off anyway you could just try my fix of glueing a small piece of plastic or rubber between the sender and receiver, has worked for me and is still working. But this is just my opinion, all the best in whatever you decide to do. Cheers

Ok Thanks, I shall try it.
One more question
Is there a way to disable only proximity sensor through OS/App? This will save my effort to remove it from board and possible damage to board.
Am working on another 7 Plus which has the gasket fitted to the proximity sensor and took some pictures so y'all can see what I'm talking about. First picture is of the gasket, second is the sensor without the gasket. Cheers
Just checked in to this forum for give Gastrocnemius a big "Thank you"!
We have a Nokia 7 Plus with the "normal" USB connection issue.
Send to repair to an independent repair station (so not Nokia), who offered a good price.
When it came back it looked fine, charging and fast charging was possible, we have been happy.
Until the first call... Black screen with dialing.
A short search showed: many problems after an update, looked like software related issue with no solution.
Shortly after the new USB connection was faulty again.
So the phone went into a drawer and replaced with a new Nokia.
Now my old Redmi 4 is too old and some for me important apps will not work with the "old" android.
I remembered the Nokia 7 plus and started to repair the USB board, also as a trial if i can handle mobile phone repairs for myself. Well, cheap USB board found, change successful... not! Broke the Display (stayed black after assembly, board from display got hot, probably cable broken).
Ok next step, new display, screen works and and charging repaired on first view.
Function check: black screen during call. Tried several proximity fix tools without success.
The app Phone Check clearly identifies as proximity sensor as "close" / near, no change.
The change to far came only when the display was way to the side. So, the sensor is working, but the function close far is not working.
After weeks I discovered this fred! Gasket? Which gasket! There is no gasket! Check with several videos on YT, yes, gasket identified!
So I tried the mentioned fix rubber band but was not able to get it working.
Then I looked for a gasket online and found one available for the Nokia 2 / TA 1007 on EBAY for a couple of Euros and ordered it for giving it a try.
I just assembled the gasket.... the 7 plus no works like new!
So I'm assuming that during the first USB-board change the gasket got lost and the check by the repair company was only performed for the charging and no more checks for the rest or they didn't care (ASUMING!)
Long story short:
If the gasket is missing you can use the one from the TA-1007!
It does look a little bit different than the above gasket but mine worked. No further assembly from the phone is required, just slip it over the sensor (make sure that the big hole is left, seen as microphone is up and sensor is up left [don't know how to describe better]).
Thanks again for the hind to the missing gasket.
Best regards from Munich,
Thorsten

Glad to hear it worked for you Thorsten!
I feel there is no proximity sensor in this phone..
Becuase while i am on call , even though the screen is touched to my ear , it will light up randomly as i am walking and turning.
Is that function managed by accelerometer and gyroscope as in new redmi phones ?
The autobrightness is also acting weird for me in some cases .

It doesn't do so for me but yes if I move my face when talking the screen turns on but then goes back off immediately. It seems that proximity sensor is managed by the accelerometer combined with ai just like it was in my old OnePlus 7Pro. However, I could be totally wrong!

While on call I tried to use another phone`s camera to search for proximity sensor ( it is ir based , so camera picks it up).
But couldnt find it

So then, my suspicions are right..It's accelerometer+ai
I think it uses the camera too. If you try unlock the phone with the selfie camera covered, it will try to prevent it.
Likewise, if you make a call with your phone placed flat on a surface, you can get the screen to turn off by covering the camera.

Yes it has one. It's near the light sensor... They are both under the display.

I dont think it has .
Even when i am on call , phone just touching my ear , it randomly lets the screen turn on .
Also as far as i remember , always on display in the previous generations used to turn off when the phone was in pocket ( or screen was covered)
But here , the aod always remains on regardless if phone is in pocket or outside .

Yes you are right. It has an ir based one like note 10,20, s10, s20...
Samsung probably is wondering if they should make it invisible with no indicator. That tiny flashing circle has caused more commotion than a midget hooker in the playpen. Every new model provokes this same discussion... talk about a fixation
Using the camera sensor be prohibitive because of power consumption. It would still need an IR emitter to work properly. Net zero gain... and a lot of added complexity at best.
You can test the light sensor with CPU-Z, cover the space to the right of the front camera, that's also what triggers display dimming no matter what adaptive brightness settings you have.
my S20 FE does the same thing on calls. super irritating... i wonder if Samsung will correct the SD card slot omission mistake on the S22. they did the same thing with the S6 and fixed it on the S7

The light sensor is there , itried with cpuz , but i feel the proximity sensor does not work properly .
It wakes up the screen during calls
