[Q] proximity sensor non existent? - Sony Xperia P, U, Sola, Go

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)

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)

[Q] Probably proximity sensor damage

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.

Proximity sensor present but no readings.

Using elixir from the market the proximity sensor is listed as being present. Where is it and why does it not display any values?

Something seems to be wrong with my proximity sensor as well..it worked before but since .13 (now on .15 and still not working)..It was working back when I was on .11.1 though.
I know this because I was trying out apps like Smart Screen Pro etc. which turn off the screen when the sensor is covered and all.
Now apps like those don't work for me anymore...and I got AndroSensor to check on my device sensors and the Proximity Sensor sometimes says failed to start, while other times it says "Waiting for event" either way, it never works now
Any help with this?
On my SGS, I had a problem with accelerometer before and I just had to delete a file and let the system recreate it and the problem was fixed. Perhaps something similar can be done with the proximity sensor since it's kinda similar to the accelerometer in the sense that well..they're both sensors of some sort lol
While it actually has a chip that supports the proximity sensor (and thus reports having one), the chip is only used for the ambient light sensor. It doesn't have a proximity sensor.

Ohhh thanks for the info! I soon realized this as well when I was looking through the apps I was testing out before.. Turns out they were using light sensor and not proximity. D'oh!
Oh well, a proximity sensor on a big tablet doesn't make much sense come to think of it.
Ya it does light sensors use more energy than proximity sensors and control via cover state is quite desirable

The Prime has a cover state sensor, its magnetic just like that other tablet it is close to the webcam. It is used by the dock to turn off the screen when you close it.
Why no other covers are using it... I have no idea.

There are some reports that the magnetic sensor only works when the dock is connected. If thats true then one would have to find a way to trick the tablet into turning on the mag sensor manually before it would be any use.
There were some people wanting to use tasker to check the status of the mag sensor for various reasons, detect if its in a case, etc. but they had minimal luck.

Hrm. No.
I have tested this already myself, going to mod my leather case to allow a small magnet on it so the screen turns off when i close it.
The right spot is tricky to find, but it is there, it works and the dock does not have to be connected for it to work.
You can try it yourself, get one of those weak magnets from the freezer and put it around the frontal camera until the screen turns off. Just remember to deactivate the auto-off timer first
Nope. It does not have one.

Can you post a pic with the EXACT placement if this sensor, if it exists?
I have rubbed a magnet over every inch of my Prime and the screen never turns off because of it. With regards to the dock it makes much more sense that a mechanical switch would dictate when the screen turns off, since this would be more reliable and since the dock hinge can function like a switch, and the dock plugs directly into the tablet usurping certain tablet functions so it wold be easy to make the dock take over the function of the power button in certain conditions.

It makes absolute no sense to use an ambient light sensor to turn off a screen. Going from a room or a place with a bit of light into a dark room would turn the screen off.
There are 2 holes on the top of the prime bezel. One is the frontal camera, the other the light sensor. The magnet is not there.
If you are facing your Prime it is to the right and a bit down of your frontal camera.
The manget is in the dock right off the track pad.
You can get the exact location with a paper clip. it will stick there.
So, here is the video...
Sadly like other user noticed, it does not work without the dock Probably happened after one of the updates, cause it was working without dock before.
I found the spot myself.
On my BBOK Transformer Prime, the magnetic sensor is just to the right of the camera, but about one inch down into the screen area. If you play with with the keyboard using a magnet you can find a magnet under the right end of the spacebar.
Unfortunately I can confirm that the tablet won't turn off in this way without the keyboard dock connected.

Proximity Sensor

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.

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.

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..... >_>

[App] Flip Case Control - Auto Screen On/Off

I had a bunch of requests for Wave Control to have this functionality. I thought it best to do a dedicated app so here it is!
Flip Case Control was designed to work with Samsung's Flip Case on the I9300 while using as little battery as possible. (I left it running all night ~8.5 hours and the battery dipped 1% more than usual)
IMPORTANT: If your case is black or dark on the inside, the sensor doesn't read correctly when the case is closed. To fix this, put a piece of light colored tape on the inside of the case where it lines up with the sensor (located next to the front camera)
Note: A Samsung based ROM is required. CM won't work well.
Here's a demo video:
Play Store Links:
24 Hour Trial Version
Full Version
Could you guys with the Flip Case test it out?
All feedback is appreciated greatly!
I would like to try it for you but unfortunately i don't have flipping cover for this lovely device as it is not here yet everyday im searching everywhere but nothing
Waiting OP to give us their opinion about this app

There shouldn't be but it is conceivable that if the case surface facing the proximity sensor is black and absorbs too much of the IR from the LED on the prox sensor then it wouldn't register a near reading.
The proximity sensor is an IR LED and light sensor. It detects distance by the amount of IR light that get reflected back off the surface in front of the sensor.
If this is the case, you could try to put a piece a light colored tape on the inside of the case where it lines up with the sensor.
Let me know if this works. What's brand of your case?

But you're right - the sensor doesn't like black. If I use a piece of lighter coloured tape on the inside of the cover it works! The only issue I have now is that the app is not auto loading at boot.

But you're right - the sensor doesn't like black. If I use a piece of lighter coloured tape on the inside of the cover it works! The only issue I have now is that the app is not auto loading at boot.

Are you running the full version? I limited that function to that version. Great to hear the tape fix worked
According to me proximity autolock works well and it is available on play store

It works OK at the moment, I think the sensitivity should be decreased though as something passing an inch or two above the proximity sensor will still turn off the screen. Seeing as flip covers get up close and personal with the proximity sensor this seems a bit too sensitive.
EDIT: Definitely too sensitive, seems to turn off at random at times. Just had a phase where it wouldn't let me keep the screen on.
Maybe a failsafe of sorts could be implemented? Leave the screen on until timeout/power button press if turned on by the power button?
Edit 2: I uninstalled the app to stop it turning the screen off constantly, but it continued even after a reboot, I went into the display settings and saw the screen timeout had been changed to "()"and this was causing the issue, as soon as I changed it back to 30 seconds it was fine. Is this supposed to happen?

Yeah, just running the trial version - that explains it.

Ah.. crap. I thought I fixed that bug before I released it. I guess there's still a way for that to happen.
I'm working on an update to help filter out false triggers and will patch that bug. It shouldn't happen. Sorry.

Proximity Autolock is a nice app with some excellent features but uses too much battery on The Note 1, an additional 8% overnight. And it doesn't work well on my Note 2.
The app works well. I bought it
It's a very useful feature that Samsung should have built in, but hey, I don't mind supporting you.

Thanks!
I agree Samsung should have made this app. When I first showed it to a friend, he said "Isn't it already supposed to do that?"
A Beta
Here's what I'm playing with right now.
It should hopefully fix the bug D3_ ran into as well as reduce the false triggers. There will still be some due to sensor placement but this should make it much less sensitive. Also response time to turn on the screen should be a little bit faster. It's working well on my I9300, hopefully it should be the same on the Note II.
Let me know if this is performing better for you guys.
Still coming:
Disable in Landscape Mode
Disable when plugged in
[Edit: Removed Old Beta]
Just installed the beta, will report back after some use of it.
V1.05
Just uploaded version 1.05 to the Play Store
Changes:
Reduced false triggers for screen off
Changed button UI
Added notice about dark cases
Updated icon
Sped up screen on response a little bit
Cant you just do this using Tasker? I already spent money on the flip cover, so kinda hesitant to spend more for this functionality (which should be there in the first place!)

Problem with Proximity Sensor

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.
