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.
Hellooo:
First of all sorry for my english.
I have a problem with my new Optimus Black. When I make a call sometimes the screen gets black and sometimes it gets black when I put it in my ear (in this case the functionallity is normal). In the first situation I can't get screen on again. I think that is a proximity sensor problem but maybe a software problem. Maybe it needs a recalibration. I search for calibration tools but not luck. What can I do?
Thanks in advance.
Hi,
I have a problem with the proximity sensor on my Xperia T. I flashed the new CM10 nightly ROM today. When I want to finish a phone call, it happens very often that the screen remains black. If the other phone hangs up, screen returns after 2-3 seconds. The proximity sensor is working perfectly if I test it at the beginning of a phone call (when it rings on the other phone). It's also working with the stock firmware from Sony, so I don't think that's a hardware failure.

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 proximity sensor is not working on any app.
But *#0*# shows the sensor value changing....
Help.?
What apps are you trying it with?
As far as I remember proximity sensor works only with phone calls, pretty much only when you talk and it can be set to off, so check your settings. I also would like to know what other apps work with the sensor?
The proximity sensor doesnt turn the phone screen off during calls.
I meant to say that those sensor testing apps on the playstore is Not showing responses with the prox sensor but *#0*# does.
I'm having the same problem... Phone does not turn display off when it's at my ear.
I had the same issue wit mu new T-mobile Note8 (pre-ordered from Samsung) I have sent it back
Mine gets stuck at 0cm. (As if the phone is at my ear) it causes the screen to be off whenever I'm in a call. I have to reboot the phone to correct the issue.
Try this app and check if it works?
Phone INFO ★Samsung★: https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
(in the HARDWARE tab > Sensors)
It will change between 8cm and 0cm.
today when I woke up, I suddenly realized that " all of the sensors" dont work!
even I tried *#0*# none of the sensors values are changing. even sensorhub self test fails!
also IRIS scanner stopped working!
isnt it STRANGE?
all of them stopped working suddenly
I have a exynos 950F, and proximity sensor does work fine with third party apps, I use gravity screen, and macrodroid mostly to make the screen on/off in diverse situations macrodoid is very useful for automation many things
none of the sensors work on my Galaxy note 8
I have the same issue, none of the sensors work, i mean proximity, gps, auto brightness, and gyroscope don't work on my Galaxy note 8.
Does anybody know what should i do?
I also rebooted my phone.
When i am on Google maps, and turn the location sensor on, suddenly the phone find the location, after that, the sensors doesn't recognize the location.
it also happens for auto brightness sensor, when i unlock the phone, it works, suddenly it stops working and doesn't change.
I tried *#0*# none of the sensors values are changing.
I don't know what the problem is? Is it about the software or the hardware?
I updated the phone, rebooted it, but nothing happened.
Hey All,
Im from Sri Lanka and i too have the same issue Non of the sensors works. I gave the device for service and as for them Samsung asked them not to do any repair but to rerun the phones to Samsung Korea and give a full cash refund till the issue is sorted . Issue begins with a official Samsung Software update and it cannot be reversed. They have done main board replacement in one phone they got but the same issue has come aft the software update and its a issue for one production batch. May be Affecting Asia region.
