Today I noticed a dimly lit red light from the second dot to the left of the front camera staying continuously on even when the display is turned off. I am not mentioning about the notification light that is placed to the left side. I tried many options but it stayed dimly lit. Later I thought of restarting the device and that did turn it off. This did show up as bright red for a moment when I turned on the device which later turned off.
Any idea what made it stay continuously on?

I was having similar problem with gs3,turned out to be viber I guess...uninstall it and report again.
I don't have the viber app installed. By the way what is this led called and what is its function?
Thanks

If its not the proper led then it must be proximity sensor(uses infrared light to detect proximity)
Normally turns on when u get a call to turn of screen when u hold close to your face.if its not viber then it might be what's app or Skype god knows what(may be try freezing phone apps one by one and find out for yourself)
Its not a bug or anything. Its meant to stay lit this way because its a proximity sensor.
turn off smart stay and anything else you might not need and it will go away
turn this off by go - Setting>Motion> Quick Glance: untick :good:
As I said it went off by restarting. I don't have the problem now to check any solution. Just was curious to know what was it.
While it was on, it stayed on even during the call or even when the display was turned off. I did not have any motion setting enabled.
Thanks everyone for your kind replies. I will see if I get the problem again

I noticed that too, then I realized what was causing this. It's the Quick Glance function on "Motion" that's triggering this, because while the screen is off the phone's proximity sensor checks whether or not you have your hand in front of the screen for activating Quick Glance. In order to do that, the sensor must continously stay on, hence the continous red light.

Anyone having a issue where their keyboard doesnt always light up? or it stays lit, then shuts off?....is it sensor reactive? to light? iunno. my keyboard doesnt light up all the time.

It seems to me to be a sensor oriented thing. In dark it lights up no problem but when in a room with light it shuts off to conserve battery? Very interesting htc.
Sent from my HTC Vision using XDA App
The light sensor is in the very very top left of the screen. When you have the keyboard open and are in a well lit room you might accidentally be reaching over the light sensor, making it think it's dark again, and therefor powering up the keyboard backlight again until you move your finger. You can solve this problem by rooting and installing Cyanogenmod RC1 which gives you complete control over all your backlights.
Agree with jark99. Looks like it depends on light sensor. In the dark environment keyboard lights up every time.

Want to know what's even cooler with that light sensor? When I hold my phone to my ear, the screen goes off. When I take it away, it turns back on. That's pretty darn cool. However, yes, it's all dependent on the light sensor. I've had a few times when I wanted to light on and it didn't, but that's rare. I kinda like that when I need it on its on, but not when I don't. Every bit of battery is important when it comes to my phone, but there hasn't been a large problem with it not coming on here on this end.
I hope someone can confirm if this is a bug or not!
Whenever I turn off my screen, and then on again it takes a second for the screen to auto-adjust the brightness up or down. (depending on the light-situation!)
Isn't the light sensor supposed to know what brightness to be at even when the screen is shut off? It's as if it first detects the light-situation when I turn on the screen. Could someone please try (in either a very dark or light room) try shut off screen, then back on and check if the brightness has stayed the same or if it first adjusts it when you've turned it on?
Why would it monitor the light when the display is off? Seems like a waste of power to me.
I doubt its a bug. More like a powersaving feature.
That's normal AFAIK.
The light sensor turns of when the screen goes off, to save a few milliamps I presume.
To my knowledge this is normal, its how mine operates as well.
Sent from my Desire HD using XDA App
It's like that on mine too. I think that all sensors are turned off when the screen is off to save battery.
[SOLVED] Bug in Auto-Brightness?
Alright, thanks for the replies. Just didn't notice it till now and it sort of bothered me.
My touch keys (soft keys) never turn off. Even when the phone is off. When the screen is on they work as they should, meaning that they do turn off completely after not touching the screen for a while, but as soon as the screen turns off, the buttons turn on, and not full brightness but dim. This happened when i started deleting bloatware, but i have already installed different roms and same problem happens. What can i do? Are there any drivers that i should check for the backlight of these buttons?? PLEASE HELP!!!!!
Do you have a text message everytime you see em light up? You might have BLN on... What kernel u running?

Check your display settings. There are options for the soft button lights including "always on."
Even when i put the setting for always off, they would stay off when im working on the phone, but i soon as i turn of the screen the touch keys come on and stay on in a very low dim.
is there any piece of code i can flash to force the touch keys to turn off?
This is for development only.not Q&A or any general.mod please move
From a glaxay better than yours.
Has anyone figured this out? Same thing is happening to me and it's annoying.
It's probably your imagination. The brightness from the screen cancels out light (the light that actually is reflecting off the buttons, not coming from the buttons) coming from the buttons when they are "off" as you use the screen and instantly or slowly come into vision as you turn the screen off. When you turn the screen off, there is no light to cancel out the light (sun's rays) coming from the buttons and you can see them. To test, go into a room with no light at all and turn the phone off. If the dim light from buttons are no longer visible, then it was just your imagination.
You dug this out the grave
Me? I just tought I'd put my thoughts and observations out there and help the guy. I didn't dig up any thread if you are talking to me.

Thats how i knew the lights were staying on, cus when i went to sleep i noticed the lights were still on. This is not visible if there's other light sources around you because the buttons light up very dim. You only notice in a completely dark room.
Did you change your settings? If that didnt work, try taking it to a tmo store.

Proximity sensor red faint light always on now , randomly turned on not sure why....
I have no motion things enabled
I tried turning off proximity sensor for phone
Ive rebooted several times
Ive turned off auto brightness
Im running the stock s3 rom rooted.
Anyone have any ideas how i can fix this?
Hmm.. My quick research of this makes me think you have a rogue app, a sticky setting or a defective sensor.
Let's be sure we're looking at the right thing. Your faint red light is just to the left of the front camera lens, correct? If so, then it's a definite indication that you're proximity sensor is on and constantly taking a reading.
Is it always on, from power on to power off? Or does it turn on once the phone has booted up? Does it stay on long after the screen shuts off during idle?
This sensor is used by motion features and talking functions. Triple check that you don't have 'smart stay' turned on, or one of the other super cool gs3 features enabled. I'd consider turning them all on manually, rebooting and then turning them all off followed by another reboot.
Lastly, take a look at your apps. Any kind of app that involves motion or talking (Voxer, Skype, certain games etc) can activate the proximity sensor and keep it on. A lot of those apps start on boot and never go away. Close them one at a time, or consider uninstalling suspect apps temporarily.
As a hardware test you can install Elixer2 from the play store (for free). Its sensors section allows you to turn the proximity sensor on and off, as well as test the near and far readings. If all else has failed, it might be nice to know that at the very least, your sensor can be turned off.
Report back with results from everything and we'll go from there.

Well i was using Viber, when i turned it off manually, the red sensor light went off. So it must be ab application that is keeping that sensor on all the time. Smart stay does not need proximity sensor and enabling or disabling it causes no change to sensors. Hope this will help ya

Thank you so much for the awesome response. I didn't find any other similar responses on the Internet other then " oh that's just the ir sensor don't worry about it". I too have viber and I believe that was the app causing the issue because of the way it integrates itself with the phone, can't be certain because so many apps updated as of late but it is gone now thankfully.
I get this when I`m in a dark room. The sensor will turn on. The only way to correct it is to restart the phone.
Plausible Solution
I don't know if this works 100% of the time, but it HAS worked for me. Go to your Viber application, menu, and then EXIT the app. Viber seems to be the culprit, so if you find exiting the app manually every time bothersome, you might be better off uninstalling the thing. Click the Thanks button if it helps =p

I recently bought a new samsung galaxy note 2 and it was working all fine till the 2nd day of use in hands, suddenly i found one of the two sensors beside the camera showing a dim red light continuously,thats probably the Proximity sensor, I tried killing applications, but not worked, restarted phone and the light vanished...
Later on i noticed, the dim red light showing up whenever i opened any logs or messages,also the light stays on when the Quick Glance feature is on, i tried turning off the Direct Call and Quick Glance feature again that red light vanished...
i've searched alot about this problem, many people having it on Samsung Galaxy S 3, some have resolved by uninstalling viber, but i don't even have viber...
the light was not showing up before, but it came suddenly...
anyone having the same issue ? or anyone who has resolved such issue...

Quick Glance uses the proximity sensor when the screen is off to tell when you're passing your hand over the phone to activate the feature.
I think Quick Call uses it to tell when you've moved the phone to your ear to dial the contact automatically.
Basically, it's normal depending on which features you have enabled/disabled.

Well..infrared light is invisible and cannot be seen.
That's why we cannot see any light coming out of the TV remotes even though they use infrared.

Dim red light galaxy note 2
Hi there just been reading over this thread and only found it as I was having the same issue. Had a gs3 before this and I'm sure that had the same layout at the top of the handset an I never seen a red light appear on that in the 3 months I had it!. Noticed about 4 days ago this dim red light on my gn2 but just left it alone thinking similar to already mentioned reasons here like proximity sensor working but past 24hrs it just hasn't went off when before I was never there so why?. I turned phone off then back on again and now no red light and I've been using it for a few hours now so I don't think its just the proximity sensor working. When booting into recovery this same light appears for a split second before gn2 boot screen Sonoma thinking there might be some sort of bug when it stays on all the time so hopefully somebody will put our minds at ease with a solution

If you bothered to read the replies, it's normal. The proximity sensor stays on when your screen is turned off and lying on a flat surface because of the quick glance feature.
The proximity sensor turns on too when you are in the address book or call app and also the messaging app because of the quick call feature.
It's not a bug, just leave it alone and let it be.

I did read the replies and I don't hav the quick glance feature enabled. I'm telling you that on MY phone at least this red light has not appeared again since turning my phone off then on again and has only been present in the last 2 to 4 days intermittently and whether that be through flashing rom (omega) or not there's is still no concrete answer because I am using my phone now as I have been since the day I got it with the same motion settings an same settings throughout so if your so sure you know why this red light stays on constantly can you tell me why over a 2 to 3 week period it has only been present on my phone intermittently for a couple of days?

Edit: just received a text and on wakening the screen red light came on again so proximity explanation would be right because it went off again once I replied and locked the phone. This still doesn't explain why it was on constantly for 2 to 4 days with all my settings as they hav always beenand using my phone even as i am now!. Its just really bugging me I hate no knowing for definite but still appreciate your reply
I also have this bug/feature. On my phone the little dim red light works as described, when in messaging it lights up in case I put the phone to my head "Quick Call" feature is turned on. HOWEVER once in awhile this light will remain on constantly. Yes phone is locked and laying on its back. The "Quick Glance" feature is NOT on, "Turn over to mute/pause" is NOT on, "Smart Stay" is NOT on.
After a couple of days, the dim red light will just stay on. If I reboot the phone, it then shuts off and comes on only when messaging as expected, considering my settings. Again after a couple of days I will notice that it is on all the time again.

I don't use any motion or anything that use prox sensor... so?
faulty prox or soft bug?
As I was trying to tell princeherman up there,its not just 'a feature' there's a problem with it and whether that through being on a custom rom or not I'm not sure but it certainly doesn't behave consistently with or without motion settings activated as it turns out because we have posts here saying they have them all disabled!. I think I've only had it happen once since my past post about it weeks ago but I've also updated omega rom many times since then as well as trying the odd different rom so it could've been any of them as I just rebooted to rectify it without giving it much thought. Strange though!,wonder if someone el get a definite explanation?
