Need help samsung galaxy s proximity sensor not working

I need help with identifying the problem why my proximity sensor isnt working. This gets annoying because my phone turns the screen off when making a call and you can turn it back on since it thinks something is all the time in front of it. Is it maybe dust? On which side is the sensor located? Is there any software update for a proximity sensor?

If I type in *#*#0588#*#* that runs the proximity sensor test. The screeen goes green, vibrates and stays on 1 all the time( doesnt flick between 1 and 0 if I i move it). What can I do?

I've got a problem with mine aswell. It is always 0 in the test (it can't sense if i put anything over it).
It use to work but suddenly sort of died. I'm not sure what the problem is too but I would like a fix if anyone can come up with one
Funny thing though, my proximity sensor worked fine for 1 call this afternoon, but failed again soon after. :/

Looks like this is one big riddle for the samsung galaxy users. :/

I made a discovery.. If i shone a bright light on my sensor and held it really close to it (like 0.5-1cm away) then the proximity sensor would react and say something is covering it. Only works with a bright light though :/

How bright is that light? May I ask you what are the other 3 values of your sensors?

hmm it was the flash from my digital camera. I think any decent light would work. Try a torch, if that doesn't work try something a bit brighter.
As for the values, which 3 values do u mean?? sorry

Light, magnetic, accelerometer.
Which rom do you have?

oh, the values for accelerometer work fine, the xyz values react as they should when i move the phone.
Light sensor goes as high as 15000 lux when I shine the light on it.
Magnet sensor: 2 and the xyz change and react as they should. same with Azimuth Pitch and Roll.
As for the rom, I'm on darky's 10.1 Extreme Edition

As I thought my light sensor is also faulty. It goes only from 0-22lux

My solution

I don't know if this helps, I had a similar problem.. After i made a call my screen would not auto turn back on for me to disconnect the call.
It may have been coincidence, but after i disconnected "Increase volume in pocket", everything started working properly again.

Sorry, I should had given this information. This happened on a S4 (I9505) android version 4.2.2.
I don't know if this particular phone has the same menus has mine, but its how i solved my problem.

Having this issue too.
Nothing mentioned so far has worked for me.
Galaxy S4 SCH-I545 on VZW running 4.2.2.
Unfortunately I don't know when it started so I can't pinpoint any apps as possible triggers. However I have tried out all sorts of apps status bar apps, active notifications apps, launchers (Apex is my current now)

how to disable Htc sensation xl proximity sensor?

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???

[Q] Screen stays off during call no matter what I do!

When I am in a call, putting the phone to my face turns the screen off using the proximity sensor. However, removing the phone from my face does not turn the screen back on. Nothing turns it back on even if I push all the buttons or hold them or do anything unless the other person hangs up. I cannot remember when it started....before or after the recent update.....but it did start very recently. Any ideas? If I turn off the proximity sensor during calls it works fine by locking and unlocking the screen with the buttons.

Is anything covering the front facing camera, or light sensor? Like a case, bad screen protector, etc....
Does your front facing camera work just fine as a camera?
How about air gestures? Do they work?
I'm asking these things because it seems your proximity sensors aren't working properly. Your phone thinks it's next to your head all the time, so it's not waking the screen until the other person ends call. We need to find out which one is acting up and why.

The front camera works, but in my office it seems VERY sensitive to light. The lights are glaring heavily. I never use the front camera so I don't know if that's normally how it was. Air gestures work when the screen is on (swiping left and right to view my photos), but the quick glance won't work when the phone is locked. The weird thing is that quick glance works when I do the "try it" tutorial only.

Ok now it seems quick glance DOES work when the phone is off....I just couldn't do it correctly.
Main problem still exists though.

What rom are you using

I was thinking that, but I'm tempted on resetting my phone and seeing if that helps. The problem is that I would lose all my app data and I'd hate to deal with that.

Unfortunately this sounds like a bad proximity sensor. This can be verified by testing the sensor by dialing *#0*#
I had this happen to my last Note 3. The only difference was I could turn the screen back on with the home button.

I tried that *#0*# test and I can activate the proximity sensor, but it seems to stay on after that.

This is a known issue with our phone. I had this issue myself. Plenty of times. Just call ATT and ask for a replacement.

Yeah I just found this:
http://forums.androidcentral.com/sa...-3-proximity-sensor-issue-during-calls-5.html

It's not a software issue use canned air and blow by the speaker and the headphone jack als o press on the back of the phone . This has happened to me

i stumbled upon this thread and took my phone apart and sure enough there was lint in it. in the dial pad using the *#0*# method, when i covered the sensor the screen would light green, vibrate, and stay that way after i moved my hand away. i cleaned it and everything is perfect!!!

Try this

Calibrate Proximity Sensor?

Is there any way to calibrate or disable proximity sensor on nexus 6? I am running resurrection remix on the nexus 6 and the proximity sensor seems to be always covered with something even though I am rocking the phone naked w/o a screen protector. Refer to the screenshot.
The main problem I am facing is that whenever I receive or make a call, the screen goes blank. ALWAYS! No matter where I touch the screen the button. The screen goes back on only on ending the call. Help me with a workarounds.
Thanks

Aside from clearing cache and reboots I'm not sure. Is there an app to reset it in the play store?

It could be dust.... Use some compressed air through the top speaker grill... It may work to take that dust and away...

Could you elaborate on what exactly you mean by compressed air?

Proximity sensors not working interferes with active calls. Fix?

After screen replacment the proximity sensors don't work for some reason. So now when I get a call I can't do anything, It's just a black screen. I can't use the phone or even put it on loudspeaker. I'm looking for some kind of software solution but can't find any. I tried going though some settings on the phone but I had no luck.. The only thing I can do is end calls with the power button :/ Could anyone help? :fingers-crossed:

There's a very small piece that goes on top of glass screen in between LCD where the proximity sensors are, if not installed your issue may rely on that.

Do you have more information on the piece that's needed? I have the black gasket on, and am still having the same issue. What components are needed for the 2014 Moto's proximity sensor?

use this app to identify name of proximity sensor https://play.google.com/store/apps/details?id=imoblife.androidsensorbox&hl=en_GB and then try a sensor disabler like this https://play.google.com/store/apps/details?id=com.itsme4ucz.screenoff hope it helps
