I just bought a Galaxy S from ebay and am facing this problem. Everything works fine on the phone and it doesnt look like there is any water damage. When I try to make a call the screen goes completely blank. I cannot disconnect the phone or do anything since the screen is blank. The only thing that I can do is remove the battery and install it again. Based on my research it seems like its a proximity sensor. I even went ahead downloaded Z-deviceTest and all hardware seems fine. I also upgraded to the official 2.3.3 from Samsung so I dont have a custom ROM, no root nothing! What can it be? Should I ask the seller for a refund or there are any tweaks for it. Any help is appreciated.

I'm not an expert, but seems related to a faulty proximity sensor indeed...

I am pretty positive that it is the proximity sensor as when I insert the headset calls can be made without the screen going blank. I dont have a screen protector and I tried to put some compressed air to see if that changes anything.
When making a call and the screen goes blank can you cover the proximity sensor for a while and see if its turning on the display? I kinda have the same issue sometimes and covering the sensor would normally do the job.

Same problem here, seems that plugging headset does the job. It is kind of lose or lose situation, even turning off (any idea how?) proximity sensor would not help as screen would be touched by ear Any other solution anyone? Or some kind of calibration? Check? Most applications from marked I have checked are crashing or showing 5cm from sensor regardless.
Does anyone else have problems with the screen not turning off when on a phone call? Mine doesn't turn off unless I directly cover the proximity sensor with my fingertip. I believe it has been this way the whole time I've had the phone, but maybe it's been worse since I went to ICS. I'm on Dark Raider right now.
I have been turning off the screen when in a call, but it would be nice if the sensor just worked. Is there any calibration tool available for the vivid? Or is this probably a busted sensor? My fiance's vivid also does the same thing.
I get the opposite. The screen turns off when put on my ear but doesn't come back when taken away from ear. Very annoying when you're dealing with an automated teller. Anybody know know anything?

Did you find a solution for the proximity sensor? My screen stays one while calling.

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.

any chance we can see the pics of these steps? thank you
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 just got my XZ a few days ago and experience only one issue: When doing a call the display turns off immediately, but when I put the phone away it's still off and doesn't turn on again. Service menu says the proximity sensor is turned on.
Anyone else with this problem and maybe the solution?

Most of the time with proximity sensor not functioning is because some Screen Protector is blocking it.
Make sure your custom screen protector isn't blocking it first, then if it still doesn't work properly maybe it's a hardware failure, should contact SONY then....
If it's the sensor or the screen protector (which has cut outs for the sensor), then why does it turn off the screen correctly the moment it put the phone to my ear?
It was the screen protector. Strange, other people don't have any issues with it.
So sorry Sony, your are great
Might be a little bit late, but maybe for others
worked pretty well on my Samsung S4.
download the app "proximity fix" from the playstore and run it.
Job done.
Hope that helps you or anyone who stumbles upon this!
Hi Guyz,
My friend dropped his nexus one on the floor and from then on he is facing a weird problem. When he receives a call, when the sensor is turned on, the screen never comes back and it remains black. The only option is to pull out the battery and i suppose the drop has made proximity sensor faulty. He is not a rooted user. Is there any menthod to disable proximity sensor without rooting ? If not how can i fix it after rooting ? Any build.prop changes ?
Thanks,
karthik

hey Karthikus , I know this is not a new post, I would like to know if you solved your friends's problem, I have exactly the same, I used a couple of apps to disable the proximity sensor but still no luck, by the way I have the cyanogen mod 7 in my nexus now. the phone is a beauty, but its kinda annoying to have to remove the battery after a few calls, also I'm using a bluetooth headset, wich kinda minimizes the problem, but still not happy. please let me know , or not, I'm planning to build a disable sensors app myself in case I can't fixit. oh, and I tried all the other solutions I could find in google, like cleaning the sensors, (I dismantled the phone already) and enabling other ways to bring the screen up using other methods like trackball press or menu press. no way, still there. so please let me know. if still relevant.
thank you.
