It's called a proximity sensor, i.e when the phone detects your ear is close by to the receiver during a call, it switches off the screen to save battery. There's an option somewhere to disable it..

Dim red light next to proximity sensor

Hi,
I just saw today, that there was a very weak red light just next to the proximity and light sensor. It looked like it was flickering at a very high rate!
I tried to restart the phone normally, but the light didn't disappear. After that I tried a reset by holding the power button down for 10 seconds. That made it vanish.
What the f**k was that all about???
Best regards
Casper
If you were making a phone call, the red flashing light is normal It's the proximity sensor. If you were doing nothing, it should not be seen the red light, might be faulty.

Its The Goverment Spyin On us...Making Sure We Dont Flash Anything Or Even Root...If So It Will Say Tampered And The S.W.A.T. Team Will Come Crashin in Our Homes...
That red light is in fact the actual proximity sensor and it's in use while in a call. If you where not in a call then that was a strange occurance unless you ran some of these sensor testing apps...
Well, I wasn't in a call. I had been calling someone through the hands-free in my car on my way to work, where I discovered it about 10-15 minutes after the call was finished...

That was an odd one... maybe it was a temporary fluke? Strnag nonetheless...
I often use face unlock. The red light turns on when the front cam turns on.

any tips on how to trouble shoot this? I wish I could figure out which app (if any) is causing the proximity sensor to stay lit.
I've heard it's related to an autobrightness tweak, but it appears even when tweak is not applied, across multiple roms. The only commonality between my roms is the apps I have installed.
I've tried multiple proximity sensor testing apps and, it's working.. it's just always lit up.

Same here. Have to restart to get it off again. Any help? (TrickDroid 4.3)
Anytime you make a call by any means other than handset to your ear, the proximity sensor will come on and stay lit until reboot or until you make another call via handset.
Example:
Place call> turn on speaker phone> hang up - proximity sensor will stay lit after call;
To fix do this:
Place call from handset (not using speaker phone or hands free) and hang up right away, or reboot device and light will go out.
Same seems to go for calls through hands free as well.
These guys are lying its a bomb isn't it obvious flashing red light HTC controls it if u do something they don't want u to do boom ur hands are no more why do u think the phone heats up so much its a warning don't believe me read the thread in forums about heats in the one s another reason they don't want us to remove back well see the bomb :what:

Hi All,
My One S also does this. I'm finding it a pain to have to make a call after using speakerphone to turn the proximity sensor off again. Has anyone found out what the cause of this is?
I've tried clearing cache partition with HTC support but still no fix.
Hi all, I forgot to mention that the issue on my phone only happens when the call is ended with speakerphone active. If I turn off the speakerphone before ending the call it does not happen.
Hey brothers.. I had the same problem with the proximity sensor not turning off.. Even after so many restarts resets... Finally I just opened the original task manager of the one x, and push "stop all" .. and YES!! the sensor was turned of and stopped lighting.. After that I tried calls with speaker phone or not.. No problem.. Now it is working how it has to...

You maybe have turned off Viber doing this: http://www.boards.ie/vbulletin/showthread.php?p=80972874
Does it come back after restarting Viber?
Sometimes a restart fixes the problem.
I had the same problem. I uninstaled Viber and the light disipired.

Later I realized that Viber is the reason. Yes. But now it seems that Viber is fixed after last update, and no red light when viber is turned on

Proximity sensor issue VZW i605

I'm having trouble with my phone screen when I'm on a call. The display turns off and won't turn on until a few seconds after the call ends. Home and power buttons do nothing while the call is active.

Did you install the sensor fix after flashing?

Sony proximity sensor bug?

Hi guys, I have a issue with proximity sensor, it happend from 4.4.2 and now i'm in 4.4.4 and still facing with it.
At the first time I think that is my app problem, so I don't care at all. But today, I found it (maybe to late) happend with all thing include call and the test in hidden menu.
This is the way how I made it:
1. cover the proximity sensor
2. start the call
-> screen go off
3. un-cover the proximity sensor
-> screen not turn on even the call ended. All thing you can do is press Power button twice
If this only happend with call, ok, I can accept it like a feature.
But when I try reproduce the issue in *#*#7378423#*#* - Service tests - Proximity Swich test, the result show that the proximity sensor cannotchange state and always "Detected".
So idk the problem is my phone or sony firmware, anyone can confirm that? I did some searching but can't find anything.
Thank you.
i think the problem is in proximity sensor because as u say it happend in 4.4.2 and 4.4.4, and i've use both firmware and i dont face any problem like that, and u can check if u have ur screen guard on ur proximity sensor, because it happens with me once i put my screen guard on proximity sensor thinking nothing will be wrong because screen guard is transparent but that my proximity sensor becomes like what u say, always detect, check it
It's not the problem of sensor, this problem is in firmware. I am facing the same problem and my frd too.

maybe proximity sensor of your device has been damaged. there are some apps which can disable proximity sensor but it needs root access
You should open the phone and check to make sure that all connections are tight and the area around the proximity sensor is clear.
If you use a screen protector, make sure the protector doesn't cover or interfere with opening for the sensor.

Proximity Sensor Issue OP7P

Guys!
Do you experience proximity sensor issues while answering calls on OP7P?
For me while I'm on calls. The display comes on and gets disturbed and get pressed by my ears all the time.
Also any idea of where the proximity sensor is located on OP7P?
Thanks ?
Yes, I'm having the same issues. While I'm on calls I often activate the notifications pulldown. It would be nice to know how to fix this.
If you pull down the notification shade, the sensor is located just above the fifth icon on the first row. IE behind the screen.
If you pull the shade all the way down it is above and between the third and fourth icons. Easiest way to describe it. Put your thumb over that area with auto brightness on to watch the slider move.
Annoying while on a call that the screen comes on.
I'm experiencing the exact same issue with the caller app.
I also tried to make a flip cover to turn screen on or off with a proximity sensor detection app and it didn't work either.
I search a little in engineer mode (*#808#) and found that there is multiple proximity sensor, the IR sensor work quite well but it doesn't seem to be the default one.
The default one seems to be the ultrasonic sensor which works really bad.
There is also a "TP" proximity sensor which seems to be a near field detection which seems to work if I move my hand near the screen.
The sad thing is that in dedicated app to use or test proximity sensor (and in antutu or else) only one proximity sensor is listed (The ultrasonic one I guess) so you cannot switch to use the one which is working well.
Isn't this in the wrong place? Shouldn't it be in the Questions and Answers section?
Mods?
Probably just here looking for a mod to improve the situation
Actually I was going to open a new thread in Q&A when I found this one with the same subject and problem.
Do you think I need to open a new thread?
Is any of you experiencing the same issue as I described in my answer?
did anyone calibrate the proximity sensor using *#808# first? That seems to fix double tap to wake for some people
I tried to with no luck but as I explain in my first message the IR sensor is only used when screen is off (that's why it could help with double tap to wake)
But when screen is on another or couple another sensors are used and you can't calibrate them.
I think ultrasonic sensor is used when screen is on.
Do someone tested proximity sensor with any app on the play store? (Like proximity sensor test)
Put it on a table and check if it's working, mine is absolutely not. If I hold it like I was about to phone it works a little but it's not impressive.
Since I got 9.5.7 (EU version) earlier this evening screen turn off when I make a call.
I'm having this issue since 9.5.8... It's very annoying and I'm really disappointed, I often turn on airplane mode during a call... I tried to calibrate but it doesn't work.
I'm very very frustrated

I've been having issues with phone calls but more so with pocket issues.. When I had the 6t pocket mode kept the phone neutral but this phone doesn't seem to have an accurate prox sensor.. Is there a way to activate a pocket mode?

Happening to me too, approached oneplus via live chat about this issue and at one point they said to wipe and reset my phone even if I told them the sensor is working but seems badly calibrated. Will try the wipe & reset and if it's not working I am returning my phone.
Proximity sensor is working fine - there is a bug elsewhere on the firmware that does not lock the screen when it is blacked out

But I have had this issue since release.. Do you a link to this information? If that's the case maybe someone can look into the firmware and see if it's minor tweak that can fix it?

I have reported this to Funk wizard on the OOS support thread and he said he cannot reproduce it anymore on the latest test build, so... We have to wait for next firmware release and see if that is indeed the case
