My proximity sensor just suddenly started to half work. When on a phone call I would cover the sensor with my finger and the screen will shut off. When I move my finger away, the screen won't turn back on. I got into the test menu to test the sensor and notice that the adc reading seems to track my finger fine but once the sensor detect my finger it always stays at "1" (with a green vibrating screen) I am close to restoring my phone back to stock with Odin to see if it will fix it. But if anyone has any other suggestions it would be much appreciated. I have an i337m running stock rooted.

if a battery pull didnt fix it, an odin restore is def the next step. then from there its a warranty exchange (ewww!!)

Well it seem like a factory reset and restore from Odin didn't work. Any other things I can try?.....trying to avoid a warranty claim as this is my only phone.

If you have AT&T, you can call their warranty center and they will send you out a refurbished phone. If you let them know that it's a brand new phone and you take care of your devices, and that you shouldn't be given a used phone after such a short period of time, they can also send you a brand new one. They'll include a pre-paid shipping label so you can return the old one once you've transferred everything to the new one.
Screen protectors and covers to close to the sensor would add craziness in the past.

I am in Canada, so I guess I will try to go back to them and see what they can do. After testing the sensor I found out a few things. The proximity sensor will work indoors but when I go out doors it doesn't anymore. With that said, when indoor lights are really bright, it also stops working.

I don't have anything covering the sensor what so ever.
In the past, having a case that was next to the proximity sensor was enough to illicit some odd behavior. If you have any kind of case with a lip, you should test without it on

I do have a case but it's the original Samsung protective cover case.
But have you tested the prox sensor without the case?
You have not confirmed that either way. If you want to exchange go ahead, but if it were me I would test everything I could first before I go to all the trouble of an exchange to find the problem persists.

Also, look into turning off the gesture and any in pocket detection to see if that makes a difference.

Hi, yes I did test without the case as well and all my gestures are off except smart stay (which I turned off to test as well) I actually went to a shop around here that had two live S4s on demo. I went into that test menu *#0*# and looked at their proximity adc values. Both display models were nearly identical in values.... (would start from 2 onward to 255 when fully covered) as mine idles at 46+ when not covered. To me, it just looks like my sensor lost its calibration, but I don't think there is a way to calibrate it. I looked through the build prop.. even tried this through the terminal :

Still no luck. I think I am going to reach out to Samsung as I found a walk in service depot near my area. This issue only really started the last few days...and it is driving me nuts

Thanks for confirming... I know these were simplistic suggestions, but some phones in the past had really touchy sensors if anything was even nearby. Hopefully you will have good luck at the service center. I didn't know Samsung even had walk in centers.

Hey everyone,
I got my Galaxy S4 (i337m) about a month ago, and loved it from the get go. Long story short, I recently dropped my Galaxy S4 on the floor, from desk high. (I know, it's my own damn fault) It was in a small protective case (cheap case from rocketfish) that only covered the back and a bit of the front). The case took most of the shock, almost shattering (my fault for buying cheap cases) and I made sure right away if everything was ok with my Galaxy S4. No scratches, screen is great, and a few calls and text messages confirmed that everything seemed fine.. except for one thing, the air gestures are not working anymore.
I tried everything, from a hard reset to disabling/enabling the options in the air gesture menu. When I test out the quick glance in the demo menu, it just automatically turns on without me waving my hand; while the other air gestures, nothing happens. I would think there would also be a problem with the proximity sensor because now my phone just goes black right after I call someone and stays black when I move away from it. Direct call from a contact page is also not working. The light sensor is still working however, because depending on the lighting my screen changes automatically.
I would like to add that I am out of my return period. I would like to add that this is a minor problem... I barely use the air gesture function and the proximity sensor during calls is not that much of an annoyance. But, being the techno geek that I am, it would be nice to figure out how to fix it.
Thanks in advance!
If anyone can help, I will be much obliged. If not, I'll just go on the same way I've been going
Although I would never advocate it myself as long as there is no physical damage to the phone that could not be attributed to normal use (this means that nothing on the outside of the phone can be cracked or even seriously scratched and both LDI's on the battery and phone must be white) you may be able to simply call warranty and have it replaced with a 'refurbished' device (i337).

I don't even think warranty departments have even had enough time to refurbish returns or defective devices to Samsung standards.
You should get a brand spanken new GS4 from them.
try that
menu-system setting-my device -accessibility- and put magification gesture off
Hope that help
Whenever I make, receive or even check my balance(which had absolutely nothing to do with the sensor), after the call is over proximity sensor still works! :crying:
Gets pretty annoying some time Later, can't work, play games, watch movies just somehow hand comes in front of it and then Sensor detects it and black out the entire screen!
Please if someone knows anything about it, I desperately need their help! Thanks. :good:
Might sound silly, but have you enabled all your Samsung Air/Gesture commands etc? -- also Smart stay/Pause?
If so, disable them.

I absolutely never enable them they're off since I got my phone but the sensor still continues to annoy me!
What should I do to stop it?
there are a few thread for proximity sensors problems... search and you will find some useful information.
but in short, there is probably some dust in front of the proximity sensor.
a temporary fix is to blow some air in the earpiece... but the problem will eventually come back.
I do this once a month.
The other thing you can do is disassemble your phone, clean the proximity sensor lens, maybe add some kind of protection to protect it from dust... and reassemble everything.

Try going to Settings>General>Application manager>All>Phone and clearing data.
If that doesn't help, try doing a factory reset.
Failing that, try availing warranty, or if you are Knox 0x1, try another ROM.

I had the exact same problem with my device... and the problem is hardware (dust in front of the proximity sensor)...
I tried everything, including a factory reset, and the only thing that fix it (for now) is to blow some air in the earpiece.
Next step will be to disassemble and clean the sensor manually
A New Development
Before when I call or receive a call from anybody the proximity sensor still worked and turned the screen off even after the call, but now my phone is acting even more weird!
After the call the headphone jack is also not working!
Desperately need assistance guys, pls help!
Hello,a week ago my proximity sensor started making bizarre things.The screen stayed black after calls etc etc. I went to Samsung in Greece and they changed the sensor.I had the phone back after 4 days...4 difficult days because I am in love with my phone but now everything is working fine. I saw a lot of threads in forums about proximity sensor problems on this phone...too bad!

Well, you could just disable the proximity sensor and turn the screen off manually by pressing power.
Phone --> Call Settings --> Turn off screen during calls.
Not ideal, but at least you can still use your phone.

Try what he says! if this do not work then, or you have to pay to get your phone fixed or find a way to fix it yourself (buying a new proximity sensor and changing it through the help of videos).The second option will be a pain in the *** and I would never try it as I am not sure if it could go well.
Absolutly same problem i gotta
my proximity senzor is still little red Everything works fine. Like test or calls but is still slightly red. When i restart phone is black but after first call is slightly red and turn black only after restart.. but works fine. Any solution?
Ok so basically I love the g2, but here is my problem, bare with me on this haha, BTW its completely stock n everything as its my 1st Android phone so didn't want to mess with it. So basically I broke my phone screen in January, bought new screen, followed a YouTube tutorial, replaced LCD+touchscreen, no issues super happy, had the odd issue where if I woke screen, would only be on for a second n then go back to sleep, but then upgraded to KitKat through computer software update, still nothing wrong, upgrade fixed the issue with the knock to wake, and then my worst day, smashed the screen again! On good Friday, ok I thought I'll just replace screen again, so I did, but when I put new screen on and tested it, all was well, until I made a phone call, the instant moment I press green call button, screen goes blank and won't come on no matter what, power button don't bring it back on or end the call, but I can hear the other person and they can hear me, had to turn phone completely n back on to be able to use it again, so I though hmmm dodgey screen, but just to be sure it wasn't the phone I put damaged screen back on, and the issue didn't appear, stayed lit up while in my hand, went off next to my ear, back on whole in hand, so I took it to local phone repair shop because I couldn't be bothered going through the hasstle getting refunds etc, they replaced screen, I went and tested it before paying them, guess what, same problem, so what exactly is going on? Has KitKat made the phone not work with a new screen other than the one I upgraded it with? I'm seriously confused and need some bodies help urgently my model is an unlocked lg g2 d802 16gb now I turned it on last week before I took it to be repaired, and it says I have software updates but I didn't bother installing them, is there a chance these could be related to my issue and possibly fix them? Its driving me nuts tbh
Chris
Hey Chris. It seems like your proximity sensor is messed up. I think the new screen you got yourself is worse quality or your damaged the proximity sensor when installing the screen.
Edit:
Please go into your phone app (where you call people) and type the following
3845#*802#
Then go into: HW Device Test and then ALC proximity test. Try testing your proximity sensor with your hand. It should change from far to near when your hand is about 2 inches from your phone. The proximity sensor is located next to the camera.

Ok thank you I will try that, I also thought a damaged sensor but when I put damaged screen back on after having the issue with my new screen it worked just fine, no blank screen when making a call, I retested it before I left it at phone repair shop, still was fine, then picked it up with a new screen and issue came back, I don't get why its been like this, I'm thinking bad quality screen and maybe try scratching the sensor area of the new screen to allow more light in? It may be to dark for it, what exactly do I do if it works fine when using that code, try another screen?
Chris
I doubt it will work when you use that method. It's just to make sure that it's the proximity sensor that's the problem and not some loose connection. And yes, a new screen would be your best bet.
Sent from my LG-D802 using XDA Premium 4 mobile app
Ok I won't try that method then lol, what if it doesn't work when I use that code, as I said I didn't have the issue with the damaged screen which I tested after having the issue with the replacement screen I'd purchased, so how do I know its not just the screen not allowing the sensor to see? Is there anyway I can reset the sensor to relearn maybe?
Chris
If you follow my steps, nothing bad will happen. It's just a way of troubleshooting the proximity sensor. I still think you should do it.
Sent from my LG-D802 using XDA Premium 4 mobile app
Ok I've spoken to phone repair shop and they agree it worth a try to see if its the screen or not, I'll let you know on Saturday after I've been and tested it
Chris
I just had this exact same issue.Turns out the inside of the screen was just dirty. I opened it up and took a q-tip to the inside of the screen and it worked perfectly after that. Also check the readings of the light sensor, as it is right next to the proximity sensor, if the screen is the problem it will likely have low readings as well.
Great I'm glad somebody else has encountered this issue, its been driving me nuts lol ok so I dial in the code that's been mentioned and what are the labels in the menu for the proximity and light sensors? I'm thinking its just a crap screen as the broken 1 worked fine after I put it back on after testing new screen, and I reckon the screen the repair shop has used is also ****e quality, but I just want to cancel it all out as I don't have the phone to hand to inspect as they still have it lol is there a picture somebody can post up to show what to not cover when replacing the screen and applying adhesive tape etc? Just so I can show them to make sure they have done it all properly.
Chris
Ok so just to update the problem, I went to the phone shop today, did the test, it was showing near all the time, but the light sensor reading was quite high, 166 or something, but I then tried squeezing the screen, index finger on back and thumb on front, gently squeezed it, and proximity sensor started showing far, and near as I moved my hand over it, but after few seconds, went back to showing near constantly, so I think its the screen not been seated, told the shop to take screen off, give it a good clean and reseat it. This sound good to you guys?
Chris
Anyone?
Bump! I'm only wanting a little extra advice so I don't end up paying more money out for another screen when it could possibly be proximity sensor? I think it was just the screen not seated properly, anybody have an idea or something else to either assure my choice or point me in another direction?
Chris
Hi all,
I recently replaced my screen with one off ebay. So far, so good. Screen looks great and I'm happy to have my phone back after a month with a cheap zte blade. However I make my first call, screen stays on as usual, put the phone up to my ear, screen turns off, I go to put it on speaker and the screen stays off. Ok, I guess there's some dust in the proximity sensor. I make another call, and the screen stays on until I put it up to my ear, so it seems it's working again. Once more, I go to end the call but the screen stays off again. Weird, I thought it was working. So I download sensors test app. When I open the app, it shows the sensor reading far. When I put my hand up to the sensor, it reads near. When I take my hand away, it remains reading near. If I turn my phone in the side it goes back to reading far. Put my hand up to it and it reads near again, and sticks when I take my hand away. If I switch apps and come back it reads far again.
I was on 7.1.1 beta, so I downloaded Feb 7.1.1 and the problem is still there. I have limited monthly data so was hoping somebody may have some ideas before I download another factory image. I have already tried proximity sensor fix app.
Thanks

My phone does that. I thought it was normal behavior. You can download an app that keeps the screen on for whatever apps you choose. The one I use is called Screen Manager Pro but there are others that do the same thing.
No screen protector right? Have a look at thread and see if it may pertain to you. Particularly the part about the missing grommet over the proximity sensor.

I'm not sure how you can make one. It seems the guy in that thread didn't have much luck. See if an official repair center is near you and if they are maybe they would sell you a grommet? Or repair it for you worst case. I bet they are aware of how critical that piece is.

Well, the bad news is, I live in a very small rural area so no repair centre nearby. However, the good news is, since I live in a very small rural area, I went to the rubbish dump and asked about the collection from my street. The bags from my house were right near the entrance with no other trash on top of them! I retrieved the old screen, went home and cleaned up and installed the grommet and I am back in business!
I never thought I would be so happy to trawl through a garbage dump but here we are. Thanks for pointing out what the problem was!

You retrieved the grommet from your city dump. That is pretty legendary!
So I've replaced the phone screen and after that, i cant get the proximity sensor to work correctly. I've tried using the phone with the motherboard not attached to the screen (dumb i know) but i was at least able to verify that the sensor works somewhat. It's like it cant see through the glass.
I'm currently on The "Final" version of Resurrection Remix.
What i've tried:
The app Proximity Sensor Reset/Repair.
The app Proximity Fix.
This terminal code/solution here.
Tried *#*#7769#*#* in the dialer but all it does is clear the dialer and nothing else. Weird, it happens with a good number of other codes too. :/ So basically its an issue in its self I think.
Resetting Cache and Dalvik/ART Cache from TWRP.
I'd settle for having the proximity sensor disable so I can make calls in Snapchat, messenger and the dialer. At least, if I cant fix the calibration :/

There's a tiny rubber grommet over the proximity sensor that probably got lost during repair. I have seen this happen several times on this forum. Usually it's stuck to the old screen.

The last guy that posted about this went to the city dump in his small town and found that tiny part. stuck to the screen that he threw out. I was amazed by that. Anyhow, some guys used a coffee straw etc, but from what I remember it never worked right. I can only think of buying a broken 6p from ebay or swappa.com/boneyard but that's a lot of money for a grommet. I'd be searching the carpet or repair area really well first.
