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.

Hi all,
I've installed TouchLockPro as suggested at http://forum.xda-developers.com/showthread.php?p=5254295#post5254295
Initial testing seems to prove that it has fixed the problem, well it's a workaround.
It senses (via the G sensor) if the phone is held upright during a call and turns the screen off- no need to rely on the poor proximity sensor.
Please test and let me know how you get on.
There doesn't seem to be any config- just install and it works.
If your proximity sensor does not work then return the device. I have no problems with it at all. Only think I would say is for it to also switch things on/off when phone not in use.
I used to have problems with the proximity sensor but it's been working perfectly since I upgraded to 1.48.
FYI- The proximity sensor does work on my phone. It just proves to be intermittent at sensing- this has been documented by other users.
The main problem is that it doesn't work very well next to hair. So I don't have any problems with the proximity sensor, but my wife (with long hair) does.
proximity sensor works fine for me as long as I don't use the keypad during a call; once i enter anything during a call (like calling card number, extensions etc) the proximity sensor stops working.
I think this bug doesn't show up when using the wired headset, have to confirm this though.
After two weeks testing I found out that the original screen protector with the two holes for the sensor makes the problems!!!
thake the screen protector out or cut it and the proximity sensor will work perfect.

anyone know what these are for?
they are hard to see, use a flashlight on the black part next to the earpiece
Proximity sensor.
There seems to be two of them, are they both proximity sensors?
1 is proximity sensor, the other one is light sensor.
Hi all,
I think my Proximity sensor is broken..... can one try the following:
*#0588# (Proximity Sensor Test Mode)
And tell me what happens when the sensor is covered?
Also anyone got suggestions on how I can fix this?
Thanks
Tony
It works for me with *#0*# then select sensors and then move your hand close to the phone.
It also works with your code, the phone vibrates and the background changes colour when my hand is 5cm above the sensor.

Can you please tell me what it says in Sensor?
In Proximity Sensor I have:
Proximity Sensor (Min/Avg/Max)
------------------------------------------
PROXIMITY: null ADC: 0 (0,0,1)
and sometimes when I cover the sensor it changes to : ADC: 2 (0, 1, 2)
Thanks
Looks like it is broken ACC 78(83,85,89) with my thumb over the sensor.
The important number is the first number (78). This must go over 10 to register as near at about 5cms , then the background turns green.

Thanks for that. Do you know if it's a firmware (I do have original Firmware on it but had CM7 on it for a while)
Looking like a faulty phone to me. These are hardware sensor tests.
a friend of mine has the same problem. We bought the telephone together but , after 1 month, his proximity sensor stopped working.
We tried the samsung diagnostic tool receiving the same information (ADC reach maximum 4).
we noticed that it stopped working after the change of the rom (with the installation of the clock recover) but I'm sure this is the real cause.
Is there a configuration file where proximity sensor parameter like gain/offset are stored?
Maybe some buggy application has changed these values.
if you have no warrenty, you can buy a replacement sensor, only about £10, it's front cam/sensors in one component
problem fixed!
Using phonetester it took 5 minutes to connect to the sensor (while with my phone it took 1 minute) but once connected , the proximity sensor started to work again also with samsung diagnostic and phone application.

what did u use to repair ?, mines says proximity: null ADC range from 1 when nothing is in it;s way to 255 when coverd...
install only apps that you trust fully

Exactly as title says. Anyone else have the official clear view case from Samsung? Does AOD work when your cover is closed? Would be pretty convenient and for some reason Samsung decided not to include this handy feature...
It's a limitation I think.
AOD require light sensor, proximity sensor and some other sensor to work. The cover render these sensor useless and then may cause problem with AOD, so that's what I think why samsung disable it.

Well the proximity sensors work when talking on the phone with the cover closed... Seems like to me this can be implemented with a minor update.

Are you sure?
I'm not sure about how this kind of case work on new device but I used to have S-view case on my old s4 and it doesn't use proximity sensor to turn display off when calling with cover closed but use motion sensor to detect the movement of the phone to guess whether I'm holding my phone close to my face (and it fail sometimes)
Maybe you can test this by placing your phone on the table when recieving call. Without moving the phone, try cover the proximity sensor and see whether the screen is off.

You are correct sir, it does not use the proximity sensors when the clear cover is on. But even with that, it uses the phone's other sensors to wake and sleep the screen... Why can't this be applied to the AOD? Just a little thing that would be nice to have.

Because AOD use proximity sensor to detect whether your phone is in the pocket and turn itself off to save battery. Motion sensor can't do that. Also for motion sensor to detect your movement it need to be on all the time, thus massive battery drain.
Does anyone know what sensor this is?
Sensor: TMD4906 PROX (6), wakeup=true.
+1 assuming you are seeing this as a wakelock like I am
It's proximity sensor.
