Hello guys...
I've a D6503 and its Proximity Sensor has been malfunctioning in bright light. While testing when I put my finger over the sensor the test shows ON and on removing the finger it still shows ON in bright light while in low light it passes the test.
I'm using existenz 5.6.5 and have a thick screen protector which is also present over the sensor.
Could the protector be the problem or it is a hardware problem...???
If it the hardware that's malfunctioning what's the solution..???
Most protectors have cutout for the proximity sensor maybe that's your issue.

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.

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.
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)
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.
Please help me:
I am using on Xperia Z2 Of the Screen Protector and Tempered Glass 9H.
But cover the proximity sensor and Off the screen during calls.
I've used the Disabale proximity sensor Xposed.
But of the Android Lollipop not worked Xposed.:crying:
Do There is Solution Direction Disabale proximity sensor?in Android Lollipop.
manual Or App?

Hi, did'nt really get your question. Do you mean, when you place calls your screen becomes black or OFF?
Bought z5 compact
EBay the screen on proximity sensor is lifting so they sensor is on always
Also a model that cannot be bl unlocked so stuck in situation any ideas going rate to replace a proximity sensor any info appreciated
