Hello,
So today i noticed on the left side of the speaker, that there are 3 sensors, both of them are together on the same place, which should be Light sensor and proximity sensor... but what about the other one more to the left? Seems pretty much like a Small LED to me.
Check this picture guys and u will see it clear enough!

Update after a test [Post #4]
Center: Proximity
Right: Light
Left: ?
Is one the light sensor for the auto-brightness thing, and the other two possibly a 'sender/reciever' set up for detecting when it's close to your face in order to turn the screen off during a call?

I believe the proximity sensor and light sensor are both together, which leaves the left sensor... i wonder what it is
May be u r right, i am dying to find out!
I will test it with a Q-tip. I pointed a flashlight with high brigthness on the sensors now, the left one doesnt seem like a LED... so that option just kinda died
Ok tested it, qtip during the call shows that the proximity sensor is the one in the CENTER.
Used a black fabric for the light sensor... with my finger over the fabric covered the left and right sensors, result: RIGHT sensor is the light sensor!
Leaves: Left sensor.... what is it?
Center: Proximity
Right: Light
Left: ?
spy cam - big brother is watching you!
beats me i hadnt even noticed it!
I would probably guess that the two closest together are a Transmitter/ Receiver pair.
It could be emitting infra-red and using a receiver to detect how far away an object is based upon the light returned.
One way to sometimes 'see' this is to use a normal camera to look at it, if it shows a white spot, there is a good chance it's emitting IR.

Hi.
I was using 2.1 (I5801DXJG5 - Ecclair) without any problems.
When i update to 2.2 (I5800XXJPM & I5801ZFJPE, tried both),
Proximity sensor dont work during calling... But under Sensors in *#0*# mode, it works fine... It just doesnt work during calling..
And builtin cam crashes time to time.
Any clues guys?
Thanks in advance.
ok... i dont what i did... but the proximity sensor works after few calls. i was thinking, every time i make a call, i'll press the power button to go screen off mode.. but after few calls, proximity sensor works...
as for camera... i turn off the use sensor aiding under location and security settings.. and cam works fine...
Hello,
I noticed that the proximity sensor on the nexus 4 is not a proximity sensor persay, it just detects if an object is there or not (digital on/off). To give you an example, when downloading the following application (Android Sensor Box), testing the proximity sensor would actually give you a number between 0-5 cm. So if the object was 2.5 cm away from the sensor, the software would report 2.5cm and so on. On the other hand, for the nexus 4, when placing a object between 0-5 cm away from the sensor, the software would report 0, when the object is 5cm or greater from the sensor, the software would report 5cm. Can anyone confirm?
Thank you

Confirmed. This is a hardware limitation of the phone.
this is very annoying. i think the volume button activates my camera when in my jeans pocket.
how do i disable the shortcut to the camera by the volume button?

I know you can take photos by pressing the volume key (an option in the camera settings) but I've been unable to find an option to create a shortcut TO the camera by pressing the volume key. Are you sure this is what's causing it?

Ah, I had no idea that shortcut existed!
Yeah, I can definitely see how this could be a problem. Doesn't look like there's a fix yet for non-rooted devices.
I'm thinking/guessing that something else is causing the issue.
When the phone is in your pocket, I would think that the proximity sensor would be covered. If the proximity sensor is covered, then pressing volume down does not open the camera app (you can try this yourself by putting your thumb over the proximity sensor and trying to use the volume down key to open the camera app; for me it doesn't open. Take my thumb off, try again, and it does open).
Is your pocket "see through" or does it possibly allow light to pass through? Or does the top half of your phone stick up and outwards from your jeans pocket (where the proximity sensor might be exposed is what I'm eluding to)?
The proximity sensor is supposed to prevent "pocket pictures". Can someone who has the problem try the thumb test? If the camera app still opens with the sensor covered, that would at least explain it (doesn't solve the prob but we'd know why).
Edit: *if* it looks to be a prox sensor issue, here's a free app to test it -- https://play.google.com/store/apps/details?id=com.tigermonster.proxfinder&hl=en

wait a minute... is the sensor by the front camera? i still can open my camera when covering the sensor. why isnt my sensor working????
EDIT: the proximity sensor app shows my sensor working. what is happening?
Hmmm... I do not know.
Yes, the proximity sensor is in the cluster of 3 at the left of the earpiece grille (camera, proximity/ambient light sensor, led).
I have read on other boards that sometimes a screen protector can interfere with the proximity sensor. Some screen protectors go over that cluster, others have cutouts for them (the one that came with my phone has cutouts). The manual suggests that we check that the area around it is clean (not sure if they meant fingerprints or what).
So, with the sensor covered up, the volume down key still opens the camera app, correct? Hmmm... oh. Does your phone answer a call by putting it up to your ear (if you have that enabled)? I think that feature uses both the proximity sensor and the motion sensor.

i have that disabled. but when talking and taking the phone of my head the screen lights up and vice versa.
why isnt the sensor blocking the camera shortcut? very strange...

I had the exact same problem. but in my case, i don't think it was the volume button, but the lockscreen.
Sometimes the phone woke up and somehow the screen probably swiped to the right enabling the camera lockscreen widget.
I disabled the camera locksreen widget and had no problems since...

i will try it. will report results tomorrow!!
but it doesnt explain why i can open camera by pressing volume 3sec while covering the sensor. the other guy in this tread cannot do that. there is something wrong with my phone...

Hmmm, my phone normally can open camera in my pocket when pressing camera shortcut.
I always use this shortcut to take a photos when I need it for "urgent" moment.
I pull in my hand to pull out my phone from my pocket, I press the shortcut, so after I pull out my phone, the camera is ready for me.
And that's normal for me.
Can you check the camera button, is it too soft and too easy to accidentally pressed?
I never had issue like you.
With or without case, it's fine with me.
since I have a case I don't have it anymore
Sent from my LG-D802 using xda app-developers app
can you guys open the camera via volume down button while covering the sensor?

Holy crap, please tell me how to do this. I have Ti Backup and can freeze it if I can figure out what to freeze.
I wonder if others have experienced this as well. when attaching to the Sensor.TYPE_MAGNETIC_FIELD sensor on a Moto 360 (Android Wear), I'm not getting any updates.
the following code all works:
Code:
SensorManager sm = (SensorManager) this.getSystemService(Context.SENSOR_SERVICE);
Sensor magnetic = sm.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
Log.i("Wear", "magnetic: " + magnetic);
with the output:
Code:
I/Wear (17471): magnetic: {Sensor name="Compass Sensor", vendor="Motorola", version=1, type=2, maxRange=4900.0, resolution=0.15, power=0.45, minDelay=40000}
but after registering a listener to this sensor, no events are ever fired.
other sensors (like the accelerometer and the gyro) work fine.
Same on the LG G Watch. I used some sensor test app to check.
