[Q] Galaxy Note 2 Proximity Sensor Showing Dim Red Light - Galaxy Note II Q&A, Help & Troubleshooting

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...
thanks alot in adv. for the responses

I don't see the problem? It's Just the proximity sensor working. ..

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.

LOL I don't know how "infra" this particular red is, but there are known cases of people having been able to see near ultraviolet... So, maybe OP is just one very special person...?

If u use another cam to take a shot of the sensor or any other infrared led as tv remotes,u will for sure see the light, just try it.

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.

Proximity sensor issue
I flashed the rom Android Revolution HD on my Note 2. Now I have the problem, that i can't quit calls, because the screen doesn't turn back on. I flashed back to the original/stock rom, but it is still not working... Does somebody has an idea how to solve that?

I got the same problem... And its draining my battery like hell....
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?

Im also having this problem came here for help im stock but rooted

Proximity turns on while texting

I've been noticing, specially in a dark room, that when I use the stock messaging app (just when I'm about to reply or reading a text) the proximity sensor turns on. I can tell because it shines a faint red. And the same happens if I start a call, naturally.
I've switched back and forth with different apps, and when leaving the messaging app it turns off, and back on when I return to it. Anyone else have noticed this?
Thanks
Is your settings\motion\direct call switched to on? If so, that sensor lights up to use that option by checking when you put your phone to your head. It'll show up if you pull up a contact's information as well (but not if you're looking through the list).

So I see, I tought it was a bug or something. Actually What most concerns me is the impact on the battery comsumption. It's a good idea to leave it on?

Red dot on the corner of the screen

I’ve got one question. I’m the owner of HTC One X and I’ve noticed little red dot which is lightning all the time only when I’m talking on the phone with someone. Do you got the same?
The red dot is next to Proximity sensor but more to the left. I’ve took some pictures of that dot (in picture it looks like blue but in fact it’s red). Any ideas of what it could be?

It's the proximity sensor and no problem it's the same for all of us
Hi, it's the proximity sensor that will turn the backlight off when you're in a phone call.
Yep. This is the proximity sensor. It senses whether you're holding your phone close to your ear or away to determine whether to partially lock the screen or not.
If you are experiencing problems with the sensor, download an app called Elixir 2, tap sensors, scroll down to proximity sensor and start the test. Move your hand towards and away from the red light and make sure the graph which comes up recognises these changes

Viber is a free messaging and calls app... try closing some of your apps, via process of elimination you'll probably find the culprit.
I did the same with viber, but it was soon fixed via an app update
you people worry too much :laugh:
Thank you. As hadmin said I was worried about that dot but I see that there is nothing to worry about. Thanks again.

Anything makes the LED besides the front facing camera stay continuously ON?

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
Sent from my GT-N7100 using xda app-developers app
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
Sent from my GT-N7100 using xda app-developers app
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.

[Q] The Little Red Light

For some reason all of a sudden this red sensor light just stays on consistently all the time when my phone is off. Has this happen to anyone else? And if so is their away that i can stop this?

does it happen while charging only or always

It just stays on when my phone is off but it's dim. Maybe i'm going to have to take it to sprint for a tech to look at it.

Isn't that the motion sensor? So the phone can detect your hand or face etc near the phone for certain things.
Sent from my Galaxy Note II using XDA Premium.
I think that is normal since mine also does that. It is some sore of sensor. Sort of creepy...
If you go to settings and then to the motion settings, uncheck the option for quick glance and this should fix yalls issue.
Ok, so your yours does the same thing also? But it didn't do that before i don't thing.
Swyped by Me & My GNII
That's one of the sensors. It can be disabled under the motion settings.
My sensor did this one before also....a reboot solved it for me though

I just turned on the Quick Glance feature and the faint red glow came on. I can't use this feature however because I use the flip case, so I turned it back off and the red glow went away.
Thanks for the help people.. i now know actually why the red light stays on for the quick glance feature. It stays on so you can run your hand over your screen when it's off so you can see the time for an brief moment.

Hi as the question says
Did anybody notice a small blinking circle (will be around 1mm size), around 1 cm to the right of the camera when you place a call on the note 10 +
or is it only me?
During calls I noticed it.
Sent from my SM-N975U1 using Tapatalk
It appears to be the prox sensor (for turning the phone screen off when its up to your ear). That's what I've been seeing in comments of other people seeing the flashing during calls.
I believe it is the proximity sensor

Hopefully a sensor and not a pixel issue. Happening to me
Yes, proximity sensor. S10+ 5G has it also.

It is the proximity sensor.
And by the way it doesn't work well at all on my S10 plus. When I am on the phone the screen would turn on and then my ear would start tapping on the screen turning things on and off.
Pretty annoying, so I had to learn to manually turn the screen off with the power button every time before I answer or make a call...
I sincerely hope they have somehow found a way to improve it with the Note
just now saw it whilst playing a whatsapp voice message. when i put my finger over it, the phones speaker will shut off which seems to confirms its proximity sensors.
i did notice after some seconds, maybe a minute, the blinking light stops on whatsapp if you are listening to a speaker call on whatsapp... i have the whatsapp on full screen mode so the green part of the phones GUI is up there...
I noticed this today also when I placed a call. I dont make calls much so I just noticed it after 2 days. Just had some free time now and quickly rushed to locate this thread I had seen yesterday I believe.
What a relief it's the proxi sensor.

Working quite well for me so far.
It shows that Samsung has the ability to create camera under screen, but they didn't most likely due to photo quality
Good to know it's the proximity sensor.
Mine appears to flash rapidly more than blink though lol.
I thought I had a defective note. Thanks for the info.

It's the same thing just like S 10
those of us coming from the Note 9 that didn't have this, it's a new thing to discover...
When I first noticed it I thought dead pixel lol but it only visible during calls iv noticed
Yes, it is the proximity sensor, it is sad that this sensor implementation does not allow third party apps to use it, I used gravity screen in my past devices to turn screen off when in pocket or turn it on waving over the sensor, but now the app became useless, I use macrodroid, but it is not as good as gravity screen
does anyone else have a problem with the proximity sensor not turning the screen off during the call over telegram, threema etc.?
