I don't have the required number of posts to insert a link, but I uploaded a clip on you tube so you can clearly see the problem (just type "weird light under glass incredible s" in the search bar)
I had to send my Incredible S in for repair because it stopped charging. That was fixed but then it wouldn't read my SIM card. I sent it back and that was fixed but now I notice this rapidly flashing reddish light (color looks different because of video quality I guess) that appears to be behind the glass near the top of the phone, slightly to the left of the "htc" logo. It is certainly not the LED; is it some other light I don't know about?!? This light come and go; it will stop if I turn the phone off but eventually starts up again. I called HTC and they had no idea and weren't allowed to access YouTube to look at the clip I uploaded. Any suggestions? There are no other problems with the phone but I don't want to ignore this if it's a red flag. If this is indeed a light indicating something, the only thing I can think of is that it is a "tech" light that only a specialist would recognize as meaning some internal part has to be replaced. There's no mention of it in the user manual.
That is the proximity sensor. Check whether you have any apps that is using the proximity sensor. ie. Pocket locker

That's definitely the proximity sensor!!! U can also see it normally during a call when its dark!!! Does your phone screen turn off when u cover that light??
Sent from my HTC Incredible S using Tapatalk
as the others have said, that's the proximity sensor. It detects if there is anything near it, like when you put the phone to your ear when talking on it.
In the "talking on the phone case", if it detects something near, it will put the screen into sleep mode so you don't accidentally push buttons with your cheek or similar.
As am84496 said, something is using the sensor and checking for proximity.
Thanks for the responses. You're definitely right. I d/led "proximity sensor finder" and the light came on when the application was started and went off when it was closed. I don't know what application(s) used it before though. Is there any way to find out what application is using the proximity sensor at a given time? Someone suggested to me that it was a sensor and that it might have shorted out. But I guess that isn't likely right? And my screen didn't turn off when I covered it; it would only do that during a call wouldn't it?

the iphone switches the screen off when it goes to your head then turns back on when u take it away. is there a simple app for this??
Phone lacks the proximity sensor the iPhone has. Fortunately, it has a plethora of other useful features (a keyboard, picture messages, etc.)

To add on to that the phone also goes to sleep when the call is connected and its just a matter of pressing the power button to get it to wake up again.
mine doesnt
Well mine has always went black when it goes up to my ear, but it would be nice if it came back on when removed from my ear.. although we dont have a proximity sensor, i dont see why it coulnt work with the gsensor/accelerometer. all it would have to do is go on when the phone is put back in the upright position

is there a setting for this?
is it possible to in fact use the light sensor? it obviously recognizes something when it turns off, maybe write up something saying "when dark below 'x' threshold, turn off screen. when bright above threshold, screen on. you would have to press the screen somewhat snugly to your face, but it sure beats nothing.

It should be possible, but no one has done anything with the light sensor of turning it back on. I'm thinking that the polling of the light sensor turns off when the screen is in standby. If we can somehow get that to work in only incall (so it doesn't have battery issues), then it should work, when it goes from little light to more light, it should act as close to phone to far away from phone.
One could even use 2 sensors for it? Maybe the Light-Sensor and the G-Sensor. So when u bring the phone to your ear the light gets dark an the position upright. (the phone turns the screen off) And as soon as it get brighter and the position is change to normal (whatever that is ) it turns back on.
I reall would love to write something like that. But so far i have no clue of writing anything for that phone. Does anyone know a tutorial for writing software for a pda?
Thx
Come on guys this would be soooo great

It doesn't actually do that when you put it up to your ear. It's a WinMo setting to put the phone in standby after a call is launched or received. What you preceive as behavior is actually a timing thing.
The guy from pocket shield managed to combine these two sensors, g-sensor and light sensor, to work together as locking/unlocking behavior.
maybe some g-sensor and lumos code can handle this thing... and create one cab solution here...
if some one could write this code it would be an AWESOME addition to the Phone. I would personaly love this as im sure many others would.
Thanks.

I have replaced the lcd/digitizer on my htc sensation xl and my proximity sensor has stopped working. Every time i make calls it goes to a black screen and sometimes the battery needs to be removed just to get it to turn back on. i was wondering if there was a way to disable the sensor through the software? or completely replace it?

i don't have any idea about the proximity sensor ,but the same thing happened to me ,when i make a call my screen shuttdown and it comes black ,i tried diffrent roms but nothing changed so i decieded to sale the phone .
i posed a post about that and dont receive any proposition or help ,with you ,we are tree presons suffuring from this bug .
i didn't sale the phone yet but before that i will taste one last possibility who is to flash my phone with Ruu ,until that time i wish you a good luck and if i found something which fix it i will post it here .
i once had the issue with screen protector on, but once i took it off, it worked fine.
definitely gotta be the screen's problem, it has nothing to do with softwares.
maybe you can try this app to disable the prox sensor http://www.androidzoom.com/android_applications/tools/proximity-screen-off_pjwz_download.html
if the app works for u, rmb not to touch the screen when u are making a call.

ok ,i will try this app and i will see if the phone respond positively .
I have a HTC Sensation XL and have also found the same issue when replacing the screen, both the speaker and Proximity sensor stopped working. After looking around for a while i found the comments on this site from a guy that obviously has come across the issue often:
psytechrepairs.tumblr.com/page/6
It sounds like a common occurrence that they fail with a screen replacement. I've also found that the light sensor and proximity sensor seem to both be on the same removable replaceable board (some sell it as a light sensor & others sell as a proximity sensor but they are both together):
www parts4repair.com/htc-sensation-xl-sensor-light/
Hope this helps.
I know this is an old thread however I have found a solution which i would like to share.
When replacing the lcd the way to fix the proximity sensor is to cover BOTH parts of the proximity sensor with Scotch tape and color the Scotch tape with a black Sharpie felt-tip pen.
works 100%
Hi,
sorry for posting here after so much time, but I have a problem. I smashed my display and ordered myselve a new one. Once I have changed it, the phone looked like everything is working just fine. Than I noticed that my Google Play Store is crashing, and a few apps were on my phone that I have deleted months ago.
My phone is ROOTED!!!
I decided to flash it again, the problem with crashing Play Store was solved.
After I realized my phone is acting crazy,first when I call someone the display goes black, and I cannot hang up or something. It looks like the proximity sensor failure. And even worse, sometimes the phone acts just like someone was using it, it writes opens apps, just like when someone is using the phone.
Any ideas???
Does anyone else have problems with the screen not turning off when on a phone call? Mine doesn't turn off unless I directly cover the proximity sensor with my fingertip. I believe it has been this way the whole time I've had the phone, but maybe it's been worse since I went to ICS. I'm on Dark Raider right now.
I have been turning off the screen when in a call, but it would be nice if the sensor just worked. Is there any calibration tool available for the vivid? Or is this probably a busted sensor? My fiance's vivid also does the same thing.
I get the opposite. The screen turns off when put on my ear but doesn't come back when taken away from ear. Very annoying when you're dealing with an automated teller. Anybody know know anything?

When I am in a call, putting the phone to my face turns the screen off using the proximity sensor. However, removing the phone from my face does not turn the screen back on. Nothing turns it back on even if I push all the buttons or hold them or do anything unless the other person hangs up. I cannot remember when it started....before or after the recent update.....but it did start very recently. Any ideas? If I turn off the proximity sensor during calls it works fine by locking and unlocking the screen with the buttons.

Is anything covering the front facing camera, or light sensor? Like a case, bad screen protector, etc....
Does your front facing camera work just fine as a camera?
How about air gestures? Do they work?
I'm asking these things because it seems your proximity sensors aren't working properly. Your phone thinks it's next to your head all the time, so it's not waking the screen until the other person ends call. We need to find out which one is acting up and why.
The front camera works, but in my office it seems VERY sensitive to light. The lights are glaring heavily. I never use the front camera so I don't know if that's normally how it was. Air gestures work when the screen is on (swiping left and right to view my photos), but the quick glance won't work when the phone is locked. The weird thing is that quick glance works when I do the "try it" tutorial only.

Unfortunately this sounds like a bad proximity sensor. This can be verified by testing the sensor by dialing *#0*#
I had this happen to my last Note 3. The only difference was I could turn the screen back on with the home button.

I tried that *#0*# test and I can activate the proximity sensor, but it seems to stay on after that.

Hey Everyone!
I am new to this site so pl bear with me if I am posting some wrong thing.
Got MOTO X Verizon running on HSPA in INDIA. Everything seemed to work good.
Suddenly after 3 days of normal use (no dropping, no dumping, no water damage), screen started to garble at uneven intervals.
With all the pain to search for the problem all over the internet I at last (i think) solved the problem.
For this I had disassembled the screen and motherboard and just pressed the golden sticker (above the inter-connecting cable on the back of the screen)
Screen works fine now, but I guess I screwed up the proximity sensor mounted on the motherboard (seemingly irreplaceable.)
When calling the screen goes black etc...( i know this issue has been cited many times...mine is different I believe)
This was working when i got the phone (waving my hand always used to start the active display).
I checked my settings for Active display, got numerous apps for the the proximity sensor testing. [ Phone Tester shows proximity FAR and does not change that value whatever i do; "Proximity Sensor Finder" shows 3.0 cm last value and does not change ever either]
Then I tried everything from the rubber gasket installation to a hard reset, factory reset and what not.(thanks to tonnes of websites and people helping all over the world)
NO LUCK!
I also noticed that the LED beside the sensor used to blink which has actually stopped. LIGHT sensor and all others are working nicely.
This is where my issue lies :silly: : " Has anyone got this type of problem? Has the golden sticker on the right top corner on the back of the screen anything to do with the RED LED of the proximity? I tried all dialers, all possible ways to bypass the Proximity but invain. I am not wishing to root this phone and I am not good with coding either. Can this be a software issue? (running 4.4.4).Is there a calibrator out there to rejuvenate my proximity?
PLEASE HELP!!
For the time being I am using bluetooth headsets (where the screen remains open).
In Kitkat?

This feature is gone with Lollipop though...
And I read you're on kitkat, but really there was a LED blinking there???
I own an xt1060. There is an LED there, but its always been less than useless for me. It never turns on. Ever. Not for calls (missed or otherwise), notifications, or charging. I've often wondered why it's there.
I can make it work in Cyanogenmod. Any stock ROM renders it useless.
when you said you checked gasket are you referring to the tinny black rectangle gasket around the led and prox censer? when i first starting working on the x i had smiler issue, the little gasket fell off and i did not notice it

Exactly the same small thing I m taking about.. God knows I dropped it or not... But when I opened it for the 4th tym... I noticed was not there.. Then I did not get it anywhere in sale and so replaced it with a small white rubber piece with 2 similarly cut holes. No luck. Where did u get it from?
BTW I believe it will make the proximity work only if the led on its left side blinks. That works like a transmitter and receive I guess.
My led won't even flash for once..
I plead to all the genius developers to device an app for proximity bypass.

You seem to not understand that even you have cut a replacement gasket, it may look perfect to you, but it can easily block the proximity and that's about it.
You should try with original one, then start pulling off conclusions if the sensors are defective or not.
Why don't you run a dry test without the gasket?

"Dry test?" can you please elaborate this?
BTW I had tried using without the gasket too. Same values on the tester apps.
If sensor is working each time the value should change at least a bit when open to light without gasket.

By dry test I meant to test it without putting the display/frame over the board and test it that way. If it's not defective you should get proper readings off it.
