Proximity Sensor Dead? - HTC Rezound

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.

[Q] Change sensitivity of proximity sensor

Is there any way to change the sensitivity of the proximity sensor. It seems every screen protector I try makes the screen turn off when in a call even without anything near the sensor. I had to cut one of the screen protectors to get around it (but had messed up a corner when applying so I replaced it)
Or is there a way to completely disable it so I just have to hit the power button when in a call to manually turn the screen on or off.

Dont have the same problem but would be helpful.
There is a distance setting in the build.prop file. You could try adjusting that and seeing if that helps.

Perfect. Changed the value (increased it from default of 60) and its working great now. Thanks for that tip.

Well after further testing seems that it didn't fix the problem. Seemed to work when I first made the changes but now the screen is stroll turning off and no matter what I change the value to I can't get the proximity sensor to work right.

According to the official Atrix manual -
http://www.motorola.com/staticfiles...s/StaticFiles/Atrix_US-EN_UG_68014798001B.pdf
Note: Your touchscreen might
stay dark if the sensor just
above it is covered. Don't use
covers or screen protectors (even clear ones) that
cover this sensor. To find Motorola accessories for
your phone, visit www.motorola.com/products.
Anyway, why do you guys keep using the screen protectors with this gorilla glass phones? I have carried Moto Milestone in my pocket for a year and D2G for 3 months and there are no scratches on them whatsoever.
I use them on every phone I get because although it is gorilla glass it can still get scratches under the right conditions and I for one do not want my $400+ phone to have a scratch on the screen. Never had a phone that had issues like this with screen protectors and the proximity sensor. Multiple iPhones, Dell streak, nexus one, droid, galaxy s. I've tried two different screen protectors with the atria and both have this issue.
I'm having issues with my proximity sensor too, but it seems that I can't make it turn off the screen when I'm talking. I'm not using any screen protector but I do have a case. It was working fine till a week ago but now I just have to block the phone every time I get a call.
The only difference is that I've installed 2 new games, maybe those are affecting the sensor?
Another thing that isn't working anymore is the auto brightness that's always set to minimum, no matter the light conditions. The phone is online for 260+ hours already (had it go to 500+ before but had to turn it off to add a micro sd card, just to be sure it would find it).

Ugh... thing is if you drop your phone, it could crack both with screen protector and without one. If you grind the screen against your keys, it will get scratched through the protective film.
If you use it normally - the chance of scratching it really small. Just my 2 cents.

My wife's phone had a screen protector on and got scratched by being in her purse. The actual screen though had no marks. The screen protectors help. Obviously each incident is different but they can help prevent some damage so in my opinion they are worth it.

Hi there,
Got the same trouble..... but I just noticed it work fine at the sun (outdoor)..... turn the screen off in the shadow..... and switch on in the sun....

[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.

[Q] proximity sensor non existent?

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)

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 .

Screen turns off as soon as I place a phone call

As soon as I get on a phone call, the screen will turn off. I will push power and then 2 seconds later the screen will turn off again, but this time nothing will wake it up unless i hold the power button until it resets. I have no case and no screen protector on the phone. Any ideas? It's driving me crazy. It wont even allow to hang up the call or anything.
Bone stock. No Root.
Sounds like a proximity sensor issue. There's a little sensor about a half-inch left of the HTC logo text on the top of the screen. It's designed so when you put the phone to your face during a call, it will turn the screen off so it's not wasting energy/blasting the side of your face with screen light.
There's a lot of reports of screen protectors causing this issue.
Do you have a screen protector on that doesn't have the area cut out for the sensor? Zagg Invisishield has a little cut out chunk right where the sensor is at, but a lot of other screen protector makers didn't test before pushing their products out the door.

No screen protector at all.
If the screen is clean in the proximity sensor area and it's still doing it, I'd go get it swapped out. Some of them actually have issues, and the others were all caused by screen protectors.

Tried it again while outside and it didnt do it, so apparently it only does it when indoors. I will go to sprint tonight and try it again. I just passed my 30 days though so does that mean I get a refurb one?

The phone is so new, there probably aren't any refurbs yet. You will most likely get a new one.

do you get another phone if you purchased via a third party dealer like wirefly or amazon?
I had the same issue....and would only happen in low light.....but I did have a zagg so I made Best Buy put a new one on and made sure it was all the way to the top....that solved the issue. My phone still turns off after I make a call but power will at least turn it back on now. Before I had to reboot as well to get out of a call.
Good luck hopefully they will let you exchange it.
+1 on the screen protector issue. Best buy put a new on for me also due to the cut-out slightly covering just the edge of the proximity sensor, thus screwing with the screen on/off issue. Once they did that all was perfect.

Since this is probably not fixable with an ota, would be cool if they added a toggle to disable/enable the sensor in call.

How I fixed my problem of the unresponsive black screen during calls.

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.

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.
