Hi.
I seam to have a strange issue with the proximity sensor on my SGS3. I just got a flip cover that replaces the default back cover. When this is covering the screen, I thought that the sensor would register this, but it don't. It does register if I keep the cover just a multimeter above the screen, but if it touches the screen just above the sensor, it does not register that it is being covered.
This means that I have to keep the flip open during calls, otherwise the screen will be kept on. It also means that I can't use any of the flip-screen-off apps on the market.
This is even an origin Samsung cover http://www.samsung.com/us/mobile/cell-phones-accessories/EFC-1G6FBEGSTA
Anyone knows how to deal with this issue?

Hi my problem is strange. After a fall mi phone HTC GRATIA is similar HTC Aria have a problem during the call. Sometimes the display became black similar a stand by and not answer to the all impulse. If i want stop the call i have to do remove the battery.....
Have you any help for me ?
thank you
I've got a similar problem. I've replaced my digitizer and done everything by the instructions I've found. However the proximity sensor doesn't work and disable the screen when calls are answered.
I've got the rubber gasket on the light sensor, didn't lost it, and the light sensor works OK. I've tried prying very gently in between the digitizer and the housing, and while I do that sometimes the proximity sensor will show a value of 3.5in, and not 0 as always. I'm using AndroSensor.
I don't mind disassembling the phone again, but I don't know what I need to fix it.
I've searched all the forum posts about it, but either people disabled it somehow, and others just say they fix it but didn't mention how.
Any help on this?

You need to get the light sensor, gasket, and the small window in the digitizer all lined up perfectly so that the light sensor is not being blocked by anything. Not as easy as it sounds.
thanks for the explanation, but is the best way to do this?
and why the light sensor shouldn't be blocked? it seems by AndroSensor that it works fine, the problem is with the proximity sensor.
These phones where manufactured by the thousands per day in some factory, there sure is a way to assemble them precisely somehow.

If it is blocked, then it will not be able to sense anything (It's like you (the light sensor in this case) are trying to through a wall (whatever's blocking it)).

Special machines used to place them accurately.
I meant that the light sensor is "blocked" by the rubber gasket and seems to works fine.
by the way, as far as I know, most electronics are assembled by hand. laptops, iphones and ipads are, so I don't think that Aria is any different.
If anyone has any tips on how to do this, since I'm sure I someone has managed to replace the digitizer on this phone? how do they do this in repair shops or AT&T store?

The ambient light sensor and the proximity sensor are two separate things, though they are right next to each other on the Aria. The proximity sensor is MUCH more sensitive to being precisely aligned.
I incorrectly used the term "light sensor" in my earlier post. The proximity sensor, NOT the ambient light sensor, is responsible for turning the screen off during calls.

That's what I assumed you were talking about.
As I've said the proximity sensor is the right sensor and the ambient light is the left sensor that is covered with the rubber gasket.
The light sensor works perfectly as I've said. In AndroSensor at least it jumps between 33 LUX when covered and 77 LUX and 220 LUX when placed directly under a desk lamp.
But the proximity sensor doesn't seem to respond at all. What perfectly aligned means, that the sensor is right below the "hole" in the digitizer plastic? if I place the digitizer and it falls into the place, how come it isn't aligned? it's not like the digitizer has where to move in the frame.

I have two Arias and they both max out at 698 lux. If you can't get it to go above 220, it might be partially obstructed.

Do you notice a gap between the LCD and digitizer that is larger than it was from the factory? I wonder if it might just be related to the digitizer sitting too far from the proximity sensor. If you press down on the top right corner of the digitizer while in a call (without covering the sensor itself), will the screen turn back on?
Possibly unrelated, but similar.
I have an identical issue with the DroidX.
It needs a "gasket" over its proximity "light source" to keep light from reaching the proximity light sensor when there is nothing in front to reflect it back.
Looks like the light source had a rubber hood over it with a pinhole directed straight out, away from the sensor adjacent to it. Thus keeping stray light from triggering the sensor.
AAARGH. To have that little rubber piece.
Erbid
after replacing another screen and this time I've done it right, this is what I've learned.
I've assembled the phone with androsensor turned on and tested the sensors all the time. It seems that they should be perfectly clean (some air spray will do just fine), perfectly aligned with the holes in the digitizer and don't have to much distance between the digitizer and the sensors.
It's seems like a hassle but actually it's not, since if you put the right tape and put the keep it all clean, it can work with no problems at all. Make sure you test everything before you close the phone completely.
hey
since my screen is broken i have this weird problem
everything is ok till
i get a call and accept, i cant get the turn on the screen
i have this problem only in CM/AOSP ROMs
Do you have a screen protector that covers the proximity sensor? I had that problem. Replaced the screen protector and now everything is fine.
The rezound is notorious for letting dust in through the speaker grill.
If you don't want to open your phone up and clean it out, search the play store for "Rezound prox sensor calibrator" and install that. You can set custom levels to adjust for the dust.
I've been having some issues with my proximity sensor.
So, I installed stock ROM from Samsung...enter the TEST MENU...and hit the SENSOR.
For what I've read, if I covered the sensor, the screen should go green and the device should vibrate.
However, my screen is already green as soon as I press the SENSOR test key and vibrates without stopping at all right from the start.
The results shown is....UNcovered: 17 covered: 251
Is this a faulty sensor? Can I calibrate it?
Is there any solution?
PS: Is there any cooked rom with the ability to turn down the ability to turn off the screen when making a call, such as it is on stock rom's?
Are you using a screen protector or a protective case that can possibly affect the sensor? If yes, try removing whatever you can remove. See if the problem persists.
I remember buying a certain protective case from Otterbox, I think it was commuter, that can trigger or affect the proximity sensor because the cut of the silicon case was not big enough. Good thing I was able to return and replace it with something else.
Dust or dirt can also affect the sensor so try checking that.
Hi there.
First of all, thanks for your answer.
I don't use screen protector or any kind case.
My S2 is quite good, without marks or scratches of any kind.
Can't tell if there is any dust inside....
Any thoughts?

You can try the following:
- Proximity Sensor Calibration
- Using a vacuum, try to vacuum the upper part of S2.
- Use an adhesive tape once or twice to clean the sensor and front camera area.
- Remove the battery for 2-5 mins.
- If you have Viber, uninstall it then check (though I think they got this fixed since late of 2012).
- Try another battery.
- Flash a new ROM (some ROMs have it, some don't, but look for Call Settings (by accessing phone icon) > 'Always use Proximity' then uncheck the option).
If problem still persists, then it's possible that it's indeed a faulty sensor (though it seems not the case at the moment). It's up to you if you want to send it for repair/replacement or you can disable it if you're phone is rooted.
Download Android Sensor Box and Hardware Disabler
Run Android Sensor Box.
Choose proximity sensor.
Look for the square icon near the bottom left of the screen, press and remember the proximity sensor's driver name.
Run Hardware Disabler.
Scan or whatever the option is there.
Look for the proximity sensor's driver name then select.
Reboot.
A confirmation will pop asking to disable the Sensor, select yes.
For ROM suggestions (with an option to disable proximity sensor when calling), you should probably asked around on some ROM non-development topics if they have it. Also, check if the ROM is stable to prevent more problems.
For anyone who is interested, here is my method for fixing the black unresponsive screen during a call.
Like most of you reading this message I had the dreaded black screen during a phone call, which makes it impossible to end the call or dial numbers for automated systems. A lot of suggestions and fixes included blowing into the upper right corner of the phone or into the ear piece. This doesn't work (or it didn't for me) because the proximity sensor which you are allegedly blowing dust off of is pretty well sealed against the outside world. I'm on firmware 1314, which is supposed to have fixed the issue, but did not.
What did work every time was to pinch the phone front to back at the upper right corner right around where the proximity sensor was. I actually later found out you could pinch the phone anywhere in the upper half and the screen would light up.
I opened up the phone, saw that the proximity sensor just kind of flaps freely with a metal back that touches what i think is a grounding plate on the frame. When you pinch the phone it shorts this circuit and makes the proximity sensor behave properly. To make the contact better I cut a piece of aluminum foil, folded it up a couple of times, and wedged it behind the proximity sensor. Put the phone back together, made a call, and voila - screen on away from my face, off when sensor is covered.
Here is a picture of what the proximity sensor looks like on the pcb. I just wedged the foil behind the circled piece and replaced everything.

This absolutely works for me, but YMMV. I used the youtube video from le55ons for disassembly instructions. It's fantastic.
Excellent work. Subscribing in case I get this issue in the future

Do you have a screen protector installed. I did and it covered the proximity sensor, which gave me issues, took it off, no issues

I didn't have a screen protector on, but i can see how it would cause a problem if it covered the sensor. Now that it's working properly I can see how sensitive it is. If i hover my finger an inch over the sensor, the screen will go dark.
Making this thread so that something pops up in google for other people searching for help with these issues.
Was unable to get auto brightness to work on my Galaxy S8 - it stayed dim outdoors and was impossible to see. The light sensor was working perfectly (showed change using the Sensor Box app), it just had no effect on the screen brightness.
In the course of things (including having my local Samsung repair centre replace the phone) I eventually worked out that it was my phone case. Specifically, the MAGNETS in it.
I can't post links yet, but the eBay item id of the case I bought is 162444029744 so you can see the sort of case I'm talking about.
When held up against the magnets, auto brightness doesn't work. As soon as you move the magnets away, the brightness instantly jumps to the right level. If I held the back of the phone up to the side of the case WITHOUT the magnets, auto brightness would work correctly.
The magnets in the case ALSO stop the proximity sensor from turning the screen off when held up to your face during calls. Just checked it then - put my hand in front of the sensor with no case, screen goes off. Put the phone against a magnet, screen stays on.
Same problem
I noticed the same with mine. I received a follow-up call from Samsung after having my phone for about 1 week. I informed them of the screen auto-brightness function not working. They told me it's normal. I had to convince them and their technician it's not.
I then backed up my phone and was about to take it in, in 2 hours time, until I saw your post. And yup, I have the magnetic case too. Same problem.
Didn't have that issue with my S6 though. Same magnetic case.
Thanks for the post.
S8 phone case magnet fix - Auto-brightness [SOLVED]
This has been bugging me for weeks ever since I got my case from Wish. Restart the phone and it all works for a moment, then the sensors fail again. Thanks to this post I took my case off and all is good.
I found my particular case has 6 small magnets in the back cover to hold it in my wallet. I removed the lower right magnet (as you look at the back) and both my phone and case are now working properly.
Hope this helps
Same issue, although mine comes from a magnetic car mount (diy).
I was just thinking of getting a magnetic wireless-charging car mount (with the metal ring that goes into the phone case)...
Apart from the auto-brightness issue, did you notice anything else behaving quirky? Was the phone getting hot, or the screen misbehaving, etc... Also, where were the mount's magnets in relation to the phone; I suppose vertically centered?
I'd call Samsung and ask, they should know best, but since it's not the engineers on the phone, but just tech support people, they'll probably just repeat the "only buy our stuff" nonsense instead of giving any useful reply
