Hello! Has anyone encountered such a problem that during the call (after selecting the interlocutor from the list), a bright greenish flashing pixel appears on the screen near the upper beam? The weird thing is that it only activates on the background when dialing calls and calls. I haven't noticed this symptom on any other screen of any application, only on the dialer background when calling. If so, why only dialer background? I was restoring factory settings and still the same .... I tried to take a screenshot but failed to capture it. What advice? (sorry translated by google)
it isnt a dead pixel is just the sensor and this is totaly normal
uff.. ok, thx

I also saw it on my A71. in the begin I thought it is a dead pixel but I think it is a sensor.
It's the proximity sensor.

Yeap... Samsung got so many calls about this over the years that they apparently made it invisible on newer models.
One less indicator
A hardware dead pixel is always dead.
If you do a screen test you'll find it's quit alive in all colors.

I recently replaced my screen and ever since the screen would go black during calls,
I figured that the sensor has
2 parts, sender and reciever
If the receiver can see the emitting light from the sender then there's usually something for the sender to bounce off, when the screen was replaced there's something different, there's nothing inbetween the sender and the reciever! So the screen is reflecting the sender back to the receiver,
Step 1 disassemble
Step 2 remove LCD board,
Step 3 detatch proximity sensor from board
Step 4 cut small line of plastic from New screen inside the viewport ( where the sensor can see through) it should be touching the glass separating the 2 sensors but its not, hence why the sensor activates thinking something is infront of it but its reflecting throug past the piece of plastic.
Cut it out carefully with a razor.
Step5. Use double sided foam or anything else that would work to block and sit inbetween the 2 parts of the sensor and the screen, I used double sided foam and stuck it to the proximity sensor rubber,2 layers.
Aslong as you seperate the 2 sensors completely it should now work again.
I will be adding pics soon
Thank you very much
It helped me to fix my problem.
Thanks. Just repaired proximity sensor using your advice!

onejay09, can you please elaborate on the screen goes dark when calling?
i have a problem after changing my lcd where i made a wrong call and wish to cancel the call, the screen goes dark, even pressing the power button will turn it on just a short moment but goes dark again, i can't seem to end the call. had to apologize to the other end that i keyed in the wrong number.
if this fix is for this problem, then i will wait for your photos on how to repair it.
thanks in advance.

Here is the solution for your request. I have requested the developer to include the option in his app for our jelly bean ROMs. I have noticed every Jelly Bean ROM has the same issue. So you download this app https://play.google.com/store/apps/details?id=novum.inceptum.proximity&hl=ru go to Smart Screen On/Off then activate it and tick Only during call option and it will solve the problem.

i have installed and try looking for the part to tick ONLY during call but i can't find it. this app seems like it is all about off and locking the screen.

Sorry this is the right app it is called Proximity Actions from Google Play (the developer developed for us by my request to solve the problem with black screen during call in our ROMs). I have corrected url above as well.
https://play.google.com/store/apps/details?id=novum.inceptum.proximity&hl=ru Go to the app first of all put mark on Start/Stop Service in order the app to work. Then under section called Actions there is the last section called Start Screen On/Off. When you open "Smart Screen On/Off" activate it with marking it. Then you go to the last section called "Only during call" activate only during phone call. And push the button "thank you" for me in here. Also go Play store and thank the developer as well. He solved our issue.

Flashing JB Rom (Linora) Fixed my Proximity sensor
As on this post i replaced my Touch and LCD panel. after that my proximity sensor stopped working. during a call screen goes black and i have to unlock the device. after flashing several ICS roms i got frustrated coz the issue was persisted. But after Flashing Linora JB rom Proximity sensor started to work fine. earlier proximity sensor software didnt pick up my sensor. but now all is good. sensor is working as it should be.

what rom were you on when you changed the lcd? i was about to try disassemble my htc to try see what's described by onejay and correct it. i hesitated to flash linaro jb rom since there are some bugs still exist.

I was on stock rom before the replacement. But rooted and s off. Then aftr the replacement i tried many other ics rom. Xl 3.6, and so on..those roms were ok.but ddnt fixed my proximity sensor and my touch screen freezes time to time. Last rom i was on is king cobra rom.it was really buggy. Couldnt even connect to the pc. Then i flashed linora..it is a pretty good rom. Can live with it and pretry fast than sense ui roms. most importantly fixed my proximity sensor 100%. But still my touchscreen freezes sometomes. I have to lock and unlock the screen to bypass that. That's my next headache.

ok. i am not having screen freezes though. i have checked out linaro, seems there are some bugs like the wired set unable to use as hands free kit and screen goes blank when receiving calls are a handicap to me. so i will stick with the ics stock deodexed rom. i will disassemble it when i find some time to see what is wrong with the proximity sensor set up, although i am doing it blindly since i can only get a vague description from this post.
your screen freeze is quite serious, you should get it checked by the same guy who did your lcd replacement.

maybe you can try downloading "android sensor box" or any sensor testing apps and check. mine is totally not working, no fingers or palm getting close to it already shows 0.0cm (means it's blocked or hardware problem).

i used proximity sensor finder. then it showed the proximity sensor is available when i was on Linora Rom. and Sensor was working perfectly fine. then i flashed Paranoid rom and proximity sensor stopped working. and i tried PAcman rom also..same result. i am wondering why my sensor working only on Linora Rom.

Hii davit,
i have the same problem here. can you elaborate more how to setup proximity action. show more detail. step by step. i have tried many way but still my screen phone goes to black n cannot turn on. i really appreciate if u could share "how to" here. i think there are alot of user looking for this matter. TQ. or u can email me at [email protected] or whatsapp me at +60129108072. TQVM :good:
Hi - I am sure that I shot myself in the foot here somehow.
I have a problem where I don't get any sort of display now when receiving a phone call. The phone rings, but the display stays black, Even if I unlock the phone, there isn't the standard "Slide to Answer" phone call display.
Can someone help me isolate what I changed? I was trying to block an annoying (and totally useless) green caller id pop-up box that kept appearing. I guess I was too successful in the blocking.
Thanks,
¿GJ?

Have you rooted your phone and tried installing any dialer? This issue can occur if your call ui app is corrupted when trying to flash Google Dialer or some other dialer app or other customisations like enabling recording.
Either that or a screen protection that's tricking the phone near sensor into believing it's still near the ear.
Dirty flash your rom to cover any apps that is creating the issue.
Unleashed by ONEPLUS 3T rooted
I'm developing app for WiFi calling.
I want to turn off screen when proximity sensor reports "near". It work fine on other phones but on S10 phone looks like proximity sensor is not even activated - there is no white dot blinking on top part of the screen.
If I make normal call or use WhatsApp dot starts blinking as soon as I start the call.
So what do I have to do in my app to make that white dot blink on Samsung S10 phone?
I'm not quite sure, but there seems some kind of known issue with the proximity sensor that dates back to at least March. Screen coming on while in your pocket, screen not lighting up when pulled back from your face during a call, screen randomly coming on while on a call, despite it being pressed against your ear/face. I've tried everything suggested and the issues remains, unfortunately I'll be returning my S10+ and going back to my S8+, pretty disappointing for a $1,000 phone.
It's always recommended to do a factory reset after an update, problems happen not only on Samsung, even on iPhones, not a big deal.
Try this?

During normal phone call my sensor works as it should.
I just don't know how to activate it in app that I'm developing.
On all other types of phones this is not a problem, since this sensor is always on. It is just S10 series that have some kind of special sensor which have to be activated. You can see white dot (left form the front camera) blinking during call... that means that the sensor is activated.
The only other app I saw apart from phone app that can activate this sensor is WhatsApp. It activates it during call or during listening to voice messages.
I also checked Google Duo, Messenger Lite and Linphone app and none of these doesn't activate sensor. So it must be something that WhatsApp knows and others don't.
I also asked this on WhatsApp support, but I was ignored of course.
Do you find how to activate it? I have the same problem in my app and it looks similar on new Samsungs (I find it out on Galaxy Note 10)
Thanks for replay.
So I bought this phone yesterday, stock and no third party app. did a factory reset inserted the simcard and recieved a sms. when screen was off, a green small notification was blinking on left upper part of screen (something like what third party apps like aodnotify do but it was better). I was amazed that samsung finally did something to fill the void of an actual notification Led. but after my second factory reset (after a 450 mb update) the feature was gone!!
I searched every where for it. tried different settings in Aod and edge light and... nothing
can anyone explain this to me? could it be an experimental feature on my stock firmware that was removed from latest update?
thanks in advance
I don't understand it either. I don't have it on screen off but I have it when I charge the phone or answer a call. Weird behavior.
That's being used as a proximity sensor I believe to turn the screen on and off during calls. It might also disable the screensaver/always on mode if the phone is face down.
thanks for the answers.
Edit: that's the proximity sensor as you said which lights up during calls, but I don't know why it was lighting up when there was no app running and the screen was off. odd behavior! perhaps accidental touch detection was acting incorrectly.
I've noticed that, unlike other phones I own (from Huawei, Meizu, Samsung), on Xiaomi phones the proximity sensor is not active outside calling screen, making the phone accidentally react to touches with face or ear when call is in progress.
As long as I leave calling screen, for example to take a note, search something on the web or to make simple calculations, things that are needed in the calling process, proximity sensor becomes disabled, meaning that if I put the phone back to my ear, the screen won't turn off like on other brands I own.
This happens on an older Xiaomi Redmi 4A, making me believe that it's a MIUI thing. I haven't got the chance to test this behavior on custom ROMs.
Is there a way to force the proximity sensor to be enabled all the time when a call is in progress, no matter what app is in foreground?

Of course but my issue has nothing to do with that setting. Even that setting is ON, proximity sensor gets disabled (or its effect gets lost) if the calling screen goes in the background - which doesn't happen on other brands.
Yeah, I know, it's a Xiaomi/MIUI thing but maybe there's a software workaround for this.

I don't have the issue you are having, I had a call this morning, had to grab some details off a text message, the little green call indicator went to the top right hand side of the screen, if I hover my hand over the top left hand side of the screen the screen turns off. I was in the house though I've not had the need to anything like that outside
