Just noticed that when I'm on a call the screen does indeed go to sleep. However when I take the phone away from my ear it does not wake up. This is a pain for I have to hit the power button to hit the end call. Anyone else have this?
make sure ur screen protector isnt covering the sensor

My zagg hd protector has a little notch that shows the tiny circular sensor and its not covered. When looking closer I notice the tiny circular sensor is part of a larger rectangular sensor? This goes left to right. Not sure if this can be the issue since if I cover it the auto brightness does work.

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)
Welp, woke up this morning to my phone screen turning of randomly as if it was against my head during a call. In order to make it come back, I had to press the lock button. Then I pressed home while still in call and locked the screen, pressed the unlock button to get to the lock screen and every time I touched the ring to unlock the phone, the screen turned off again. This forced me to yank the battery to get the phone back.
Same thing happened after another call, so had to reset again.
Downloaded AndroSens and under the proximity sensor tab, it says sensor_Status_unreliable and the number/bar stay at 0 regardless of whether my hand is over the sensor or not.
Is the proximity sensor in my rezound toast?
Some people have reported dust making it go wonky.
Do you have a screen protector covering the sensor on the front... I have had this issue. Just cut the protector around the sensor if that's the issue

Unfortunately, no dust on the top of the screen and I don't see any under it. I'm familiar with pulling the phone apart, but don't really have the desire to do that just to check for dust haha.

I do have a protector, but it already came with notches around the sensor and FF camera.
I have the same probably but mine is from the digitizer "floating" up because the glue is weak underneath. If i push on the screen by the proximity sensor to push the digitizer down again the sensor works again. Haven't been able to fix. Maybe your digitizer is loose also.

Floating digitizer? Never heard of that before.
That's new, but sounds right

Yeah mine is loose but only on the left side so my screen is tilted although it hasn't affected anything else it's still very annoying

I've sent two rezounds back for the same problem. Call Verizon, they should replace it for you.

You can try blowing out the speaker grille at the top of the phone with condensed air. Might clear any dust. Otherwise, call verizon.
I would rather not have to return to verizon and get a refurb if i can help it. I got the phone in November when it first released, so I'll definitely be getting a refurb. Oddly enough, androsens had it working just fine last night before bed. Put my finger over it, sensor went to 9/9, removed finger and went to 0/9. Repeatable for 10 minutes.
Then this morning it isn't working again. I can see the faint red light inside the housing for the prox sensor is lit. I might try blowing it out and disassembling/reassembling to see if I can fix anything.
Thanks all.
After I updated my Nokia Lumia 920. the screen turns off when im dialing someone, and the only way to get it back is to restart it or if the person on the other end hangs up.
Could it be the light sensor? or is it just the phone update that messed it up?

Thanks!
I will return it tomorrow, since im not ready to open it after 20 days of use
now its REALLY FIXED but need to open the phone (only two screws )
Symptoms:
Experience screen and touch sensor switch off during a call, Notifications (the screen stays off, like if it was in a pocket) which doesn't turn on as usual.
Try:
If during a call you press and hold the upper left corner of the glass -just between the speaker and the upper left corner- you will notice that the sensor works as expected.
I think :
Because of the layered nature of the phone internals design and the heavy use of ribbon connectors it had to be tight to connect the board with the sensor.
My Solution:
I just added a peace of sponge (W:4mm/H:5mm/L:15mm) (all weather door and window sealant) -that comes self adheasive from one side- and sticked a small peace on the board on the opposite side of the phonejack/secondary mic connectors (Pictures attached) this will add pressure on the board to be more tight tried it and working as normal.

Mine is suffering the same issue. In the Nokia forums one user recommended to "blow air" across the top of the phone where the display meets the case right above the Nokia logo. I did this and now my proximity sensor is working. It's got to be dust getting on the sensor. I'm going to take mine apart and see if I can come up with a seal for the FFC and proximity sensor.
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.
Noticed when I make a call from my car the screen of my V30 turns off after a few seconds. Is there a setting that needs to be changed?
Do you have something covering the proximity sensor on the front?

Nope - the screen also fades to dark - phone is in a holder on the vent of the car.
