Light's Sensors Problem! - Galaxy Note II Q&A, Help & Troubleshooting

Hi everyone
I bought my Galaxy Note II (GT-N7100) from local phone shop in Cambodia last month. I really love this phone because I don't have to wait for anything I want. But it has problem with light sensor. I always put screen brightness by automatic and for the first several days it work fine but after that when I use it outside under sunlight the light sensor didn't automatic brighter the screen and then I have to go to setting and unchecked the automatic option or I need to restart my phone to get it to work.
Is there any solution for this problem? it really annoying me.
Thanks you in advance for any help. :crying:

[Q] Galaxy Note 2 Proximity Sensor Showing Dim Red Light

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.

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

GPS and auto brightness toruble

hi all..
My GF just got the note 2 and it's having some issues with the auto brightness and GPS connection..
I've got an S3 (wanamlite rom) so I'm comparing the problems to this.
First.. the only way to get the GPS to lock is to reboot the phone first.. if the phone has been on for a while the GPS will NOT lock at all... my S3 locks in <10sec always.
second issue is the auto brightness, it fails to go into full brightness in direct sun light.. in the *#0*# option the note's lux reading is about 1/2 of my S3's always
anyone else have trouble with any of these things??

Display Dimming/Tint Issue

Hi Guys,
This is my first post so apologies in advance if this is not the correct place to ask this question or if I don't particularly explain the issue I'm having properly.
Something incredibly annoying and frustrating is happening with my display every night. I notice that around 7pm each evening, my phone will go from a nice crisp looking display to one with a yellowish/warm hue. It's as if my blue light filter is on but when I check, it's definitely off. I turn it on and nothing changes with the display, but when I turn it off, the display goes back to how it previously was. I am currently using the adaptive screen settings, auto brightness turned off, and blue light filter turned on with the customer schedule of midnight to 9am. I've also tried turning off blue light filter altogether but still run into this issue. It keeps happening every so often in the same night even after I've "corrected it" using the method of turning on and off the blue light filter.
Is this to be expected with the adaptive screen mode? I love how vivid and bright it is during the day, but despise the yellowish tint at night. Could it be possible that the blue light filter is somehow turning on by itself even when I've turned the feature completely off?
I appreciate any assistance. Samsung tech support was not particularly helpful and told me to go to Costco where I purchased it from and return it.
Thanks,
Cam
Have you tried configuring the color balance in the Display settings?

Thanks for your reply. I haven't tried that yet because I figured it didn't matter what setting I adjust it to as the display would automatically change in the evening anyways.

It's strange that even you already turned off Blue Light Filter, it's still making it dim. I find the dimming helpful since it doesn't strain the eyes at night. You could try reflashing the software for the phone.

I agree, but I would like for it to be turned on later such as 1 hour before I go to bed.
At 7pm PST this evening (about 15 min ago), the screen regained it's yellow tint again. I turned on the blue light filter, then turned it off to get it back to how it was initially previous to 7pm.
The Samsung support rep asked me to factory reset my phone, but that didn't work either. Would that be similar to flashing the software? I can certainly give it a try but was just wondering if the factory reset essentially did the same thing. I'm really not sure what this could be.

It's the custom schedule for the blue filter. You can change it in display settings.

This does not fix it. I have my custom schedule set to enable at 8:00 and disable at 8:01 but it still turns on at 7pm.
Finally figured it out!!! Go to Google Play Books. Open a book and tap the screen to find the letter A. From there go to settings and turn off the night light. Whew! This has been bothering me for months!! Hth!!
I'm having the exact same issue except I've turned off/on the blue light filter a million times and it doesn't fix it.
I also don't have google play books installed so it's not that. I've tried messing with every "display" setting but nothing fixes it.
My phone did this same thing a couple months ago and when I woke up the next morning, the display was back to normal. Now it just did it again but even though its a day later, my display is still all messed up (not as bright and crisp, has a yellowish hue to it).
Anyone got any other ideas or does this sound like some kind of hardware issue?
I had the same problem specially when I go to sleep at my dark bedroom, my phone is Samsung Note 8, and I just found the solution. Turn your phone to the otherside, look at the main Camera, mine has two cameras, a flash, and a rectangle black sensor at the end. I covered this sensor with a thick black paper that I found from a brochure, taped it in place, and Wala ? no more screen dim.
WOW

Question Issues with proximity sensor and pocket mode with my OP9 Pro

Hello to everyone,
I bought my OP9 pro 2 month ago, and I loved it since first day, but there are some bugs that I really hate!!
When I finish a call or when I finish to hear a voice message on Whatsapp, the brightness goes down, without I touch anything!
In last days I find another annoying bug, sometimes when i put off the phone from the pocket, the pocket mode remain activated, also if I turn my OP, also if I unlock the smartphone... These two bugs are getting me crazy!
Can anyone help me or I have just wait some software update from OnePlus?

I've exactly same bugs on my OP 9 Pro , sometimes brightness goes down by itself and without touching it, i've always automatic brightness switched off! Then taking it out from Pocket with Pocvket Mode switched off, i find apk opened by themselves, so a total mess!

Yes! The same for me! I'm rally freaking out! And Oneplus doesn't care about these bugs!
I had the same problems, but interestingly I face it only when my Camera and Mic is turned off.
for me it was dirt an pocket lent, the sensor is very sensitive for some reason so when ever i get that problem I wipe it and it works flawlessly for the next few days until it needs to be done again
Same here, sometimes I can't even turn on the screen after a call...

I don't think so, I've already tried to wipe it, but nothing changed! I have this problem since first day... I thought they resolve it with an update, but after 4 months I'm still waiting
Hello. There is a solution to the problem with the proximity sensor. You go to the dialer enter *#808#, looking for "Device dubbing* and there are "proximity sensor test", tap and choose "infrared proximity calibration". You calibrate the sensor. it should help you. You can also calibrate other problem sensors. Try it with a brightness sensor too
