In the app Sensor List there is listed a proximity sensor, however I have only heard of people saying the Prime has no such sensor.
The sensor is listed as: Intersil isl29018 Proximity sensor
It doesn't seem like the app can get any readings from the sensor though. Is my sensor broken or what?
Dont see why the TP would need a proximity sensor, its not like your gunna be putting your face on it !
The app is probs just detecting the light sensor as the proximity sensor or similar ..

Then how do you explain the listing of "Intersil isl29018 Proximity sensor"? Other apps list the same thing. Try it.
Elixir 2 lists a proximity sensor as well, and actually shows it as active and drawing power. But, the app doesn't show it as responding. So, who knows? Maybe proximity sensor functionality is part of a multipurpose sensor, only there's no component to actually take the required readings?
Actually, yes, that's my guess. That part number is a light and proximity sensor, and there's likely just a component to enabling the light sensor part.

Already have tried it. The TP doesn't have a proximity sensor.

Actually, you're wrong. The Prime has a proximity sensor--only it's a light and proximity sensor (check out my link above). The proximity sensor functionality simply isn't enabled in the Prime.

Wrong. There is a light sensor, but it isn't a proximity sensor. Check the FCC materials.
actually i think the prima has one.
I think it is inside the dock. Because androsensor (app from the market) gives me an error on this sensor when the dock is not pluged in.
When i plug my tablet in the sensor says no signal.
Can be a bug, but mayby the dock uses the sensor in the hinge to see if it's open or closed?
There has to be the sensor its used when you close the tablet when plugged into the dock that's how it now to shut the screen off

This could be the case, that it only activates it when coupled with the dock. However, pretty sure I haven't heard of people accidentally putting it to sleep using its touch-screen while docked, so I doubt this is the case; more likely there's a mechanical switch on the dock that let's the Prime know when to turn the screen off.
As linked above, the proximity sensor is one and the same with your light sensor (pretty sure it's like this on my phone too... will have to have a look just to be sure). We just have no need for it to be used: that being said, I wonder if dev's can unlock it just for the hell of it

Easy to prove/disprove. O have tried it when I 1st got the Prime. Put it in the dock. Close it most of the way, leaving it open about an inch or so. Put your finger over the light sensor (about 2 inches to the left of the camera) It does NOT put it in sleep mode. Close it the rest of the way. It goes to sleep. Shine a bright halogen light in to the area at top of screen, after just cracking the tablet and doc apart a fraction. It does NOT come out of sleep. There seems to be a mechanical switch in the hinge. Which I am not very thrilled about. Too easy to break, the light sensor would probably have been more durable. Another great engineering decision by Asus, going for the "Persistent Perfection" or a reasonable workaround to simulate it, LOL!

while the light sensor would have been more durable, it would also prevent deep sleep mode as the OS would have to constantly read the state of the light sensor for keeping screen off and for turning it on immediately upon opening docked tablet.
Magnetic
I think the Prime has a magnetic open/close detection system.
In a hardware thread someone observed that the Prime will switch off the screen if a magnet is placed in the upper left quadrant. And since the dock is quite magnetic right of the touch pad it seems to fit. I never tried it with a magnet myself though.

There use to be a GPS sensor listed in the specifications too. I'm guessing if it doesn't work - it will just mysteriously disappear.

Eh, I think I'd hate using a proximity sensor for this. The explanations about magnets is interesting, and definitely not an easily-broken method.
Really though, I plan to use my touch screen even when docked and would be pissed trying to swype/tap/play anything and accidentally send the tablet to sleep.
If there is no light sensor how do you explain the "auto" brightness? It has to be sensing something from somewhere. Unless we're talking about something else here.... cuz i kinda just skimmed through the posts..... >_>
Hello,it seems there is no Q&A forum for this device, so here is my doubt:
Although the tech manual for the xperia S from the sony website report a proximity sensor, I fail to find one on my phone.
There seems to be a black oval spot on the glass next to the light sensor as if some sort of sticker can be removed to install the sensor.
The light sensor seems to work, since I've seen the screen go darker and brighter, but when I'm in a call and put the phone in my ear the screen wont shut off like in my old SGS nor will it turn on when I move the phone away from my face.
are your phones like mine? or is mine a defective unit?
I guess ur device has something wrong with it.
By the way; did u place a screen protector?? Coz if u did that may be the problem!
I think the light and proximity sensor are the same.
There is something wrong with your phone,maybe you should try to flash a new firmware.

Hi,
Mine works fine...
Do this:
1>Go to dialpad and type *#*#7378423#*#* (*#*#SERVICE#*#*)
2>A menu pops up in that u will see service tests select that
3>Then scroll down and select Proximity Switch
4>Initially it will display as OFF. Now u place your finger or hand on the Proximity Sensor, then the value of Proximity Switch on the screen will change to ON.
If this is working then the sensor is just fine u need to update the firmware else u need to go and replace the piece IMO though.
Thank you all for the feedback.
I used the service menu to check the sensors ...
indeed the proximity sensor is always off, even when I put my finger on it, it seems someone forgot to remove the black paint from behind the glass, but I will update it anyway to make sure before returning it.

sensor is IR, so darkened window is normal for it. but if it have always closed windows - than its status must be always ON. so, most likely you have faulty sensor (or bug in firmware)

Hi,
Exactly it should be showing status as ON if it's covered replace the piece as soon as possible

If it was covered by the glass/ cover it would show OFF because the glass doesn't radiate heat like your body does.

Proximity sensor on phones does not react to heat. It have simple IR transmitter, which emits a beam, and IR sensor, which react on reflected beam.

You are right, just tested it and it seems to be a reflective sensor.
thanks for the tips, it was indeed a faulty sensor and they gave me a new phone right away .
I hope I don't get any more problems like a yellow tint :X (knock on wood with fingers crossed)
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?
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.
Does this table have a magnetic sleep/wake function? I cant figure out if my case is defective, or the feature doesnt exist.

Not sure. don't have a case in hands.
But quite possible, since it has light sensor and also a ambient function in display menu. So it may have that sleep/wake function even without magnet.
It doesn't seem too. I have two cases with magnets and neither one wakes up the device. You have to use ambient sensor which is not as consistent.
It doesn't have a magnetic sensor. To compensate, I now use Automagic (it's like Tasker) to turn the screen on when the venue is moved to a vertical position.
