Anyone seen their light sensor get 'stuck' or just badly calibrated?
Mine reports super low values unless you hold it right up to a light bulb, then it says 'dim room' or something similar lol.

This all started happening after I tested out killswitch application (which uses the light sensor) which I think killed it. I've uninstalled and rebooted but now my light sensor is stuck in above state.
Anyone know how to recalibrate?
Bump and even more confusingly, I'm now on overcome 2.0 rc1 and even full restock and flash to new rom didn't fix it. What the...

Its a known Issue to samsung light sensor auto brightness is screwed. They fixed it with Galaxy S2 upgrade. I wish someone would port it for our tabs
oh snap it was working OK before that app broke it, no joking.
And the broken-ness carried across a full restock and upgrade from Overcome 1.45 to Overcome 2.0 (froyo --> gingerbread). So something is very weird, I hope you're right and that its a SW problem not hardware.
Also lightsensor problem with brand new Tab 7.7
I also have a problem and nSamsung doesn't even answer to my cries for help (Samsung Belgium redirected me to Samsung the Neteherlands and they do not reply at all).
I downloaded different luxmeter apps and general sensor apps they give as measurement result 12, 120 or 1200 lux (seems they output the range or lower or upper limit of the range the sensor is on, not the actual value). The sensor datasheet says it has a resolution of 1 lux.
Any solution would be much appreciated, I intende to use the sensor as a luxmeter and write an app for it taht needs the luxvalue ! But as it is now, the tablet is completey useless for this because the OS/driver software not working properly
My phone keeps turning brightness way down by itself with this message. All temperature readings are fine. Any ideas?

I too am having the same issue, however i believe that my issues is slightly different from yours. I noticed maybe about 2 days after i purchased the phone that mostly anytime I am using the browser, whether it be Chrome or the stock browser my screen automatically adjusts itself. I went into settings and made sure that the brightness was not set at "Auto" and turned all the way up. I also made sure that reading mode, auto adjust screen tone, and color adjustment were all turned off. I also changed the screen mode to dynamic and I seem to still have this same issue. I read on another forum for T-Mobile users that there are a lot of consumers experiencing this same issue, not sure if carriers are doing swap outs for the phones as this may not be related to a HW issue but rather a SW issue.
That sounds exactly like what I'm experiencing. Except I work outside, so when it does this it's impossible to see my phone. If you get a chance the next time this happens can you go into settings and open the brightness slider to see if you also can get this error message to appear? That seems to be the only place I find the message, it doesn't just pop up or anything. I too have checked like 10 times to make sure all the other display settings are correct, like automatically adjust tone and such. It sucks that auto brightness cannot be fine tune with the slider like it could on the note 2. I'm finding it very strange that instead of adding to features of the Note 2 to make this phone better in every area they chose to remove some great features leaving me wishing I did not upgrade.

It sounds like thermal throttling. LG phones have this, in particular the Optimus G and G Pro. I haven't had the problem on my G2 yet. It's designed to lower the brightness and lower the cpu speed in order to keep the phone from overheating.

True my LG Optimus G pro does this but there is a way to turn it off in the system menu accessible from the dialer. I have turned mine off and the phone no longer does this and has not gotten hot or anything. Wish there was a way to do this on the samsung as my S4 exhibits this same behavior.
I'm thinking about getting a Note 3 today so I'm hoping can be shut off too. I shut it off on my G Pro and the G2 doesn't do it, which I'm very thankful for since I work outside as well.

Since we're on this subject, how often does it happen on the Samsungs? I would figure less often due to amoled not being as bright as LCD.

You may be better served to leave the auto brightness checked when your working outside. When on auto, it gets much brighter when needed than with the brightness slider cranked all the way up.

Note 3 automatic brightness settings problems
I have a Samsung Note 3 phone bought in Germany. I have the some strange problems with brightness settings too. Typically from time to time the phone screen just get too dark. Particular in economic mode the phone can get from time to time very dark and even setting auto brightness to +5 does not help.
I was using before both Iphone 5 and the first Samsung Note and some other phones and automatic brightness control was always working fine. In my new Note 3 the brightness is jumping sometimes suddenly.
JVogle: You can adjust the automatic brightness by pulling slider up or down. It can by set from -5 to +5. But in my case this thing do not help so much. Particularly this is a bigger problem again in economic mode.
This is rather a software issue, because when I switch to manual brightness it stays constant all the time.
Anybody knows how to cure it?
This is so annoying. Gotta wonder if it's a bug in one of Samsungs ****ty features causing it to happen so much. Even without brightness all the way up it happens

You have a different phone than me apparently. Also a different issue, as I'm referring ONLY to manual screen brightness setting. I would expect fluctuations with auto brightness. I've never had a device fluctuate when manually set to a desired % though. I also can't believe they removed the ability to adjust slider with auto brightness. Sadly the only thing better about this phone than my Note2 is the specs. The software and user experience has been sub Note2 for me in every aspect. I will most likely be switching back to the Note2.

brightness issue
I have tmobile and I've had my phone for about a month and now I notice when it's in standby and I hit the power button to wake the phone the screen is really dim for about 10 seconds or so and then it brightens up. My brightness is on max and the auto brightness is disab
Hi, I have noticed the pink tint to the screen when using adaptive brightness below 30-40% and was wondering if it effects all devices.
I have read a lot of people talking about it and that it happens because the screen goes so dark and some people are saying that it is supposed to happen. Is this true and if not is it effecting all devices?
I am on my 3rd device now the first one i took back after a few hours as the screen was tinted really yellow and uneven and my second one had image retention pretty bad and would happen after 5 seconds of the nav bar being displayed and i dont know if it effected them as i didnt try adaptive brightness as i didn't ha e them for long enough.
The one thing i find really weird though is that i have been using the lux app to test if it was to do with the phone going so dim and while there is a slight pink tint when putting the brightness down on the lux app it is no where near as bad as when adaptive brightness is being used and the lux app goes a lot darker.
Thanks.
I've seen all does it specially at night. I consider this is normal
Its because you're brightness is below 0. If you use adaptive brightness at night its lower than 0 without adaptive brightness. You will see the same thing if you use the lux brightness app.
Edit: I noticed you used the lux app, you're correct its not as bad with it, but it's still there. I could be a software implementation or a bug for all we know.
So it is actually on all devices and not a select few?
I got 7 days to return it for another one but if it is on all devices and there is nothing that can fix it i dont think there is no point in risking it for another nexus 6 that could have a worse screen like uneven colours.

This is more of a feature than a defect, frankly...
Not that it is pink, but that it can be dropped down as low as it can.
Basically, there is a minimum brightness threshold. The lower the brightness, the less power it consumes. If you set the brightness below a certain point, the colors (because of the nature of the amoled) will start to mess up a bit. Most vendors will set the minimum brightness high enough to not have this happen. Google sets it a bit lower to save a bit more power, without making the colors go *entirely* crazy by setting it WAY too low.
Its made like that to conserve power. All nexus 6 are like that
I thought it was a defect too until I started researching and like someone suggested turned off adaptive brightness which made the tint go away completely even at lowest brightness setting.

Adaptive brightness is actually a really nice feature.
If the pink bugs you too much, you can (if you know your way around a compiler, that is...) bump up the minimum a little.
What if adaptive brightness is off, and the brightness is set to at least 70%, and the pink tint crap still happens? kernel issue? nougat issue? Because it's very annoying, randomly happens to me. usually, going into twrp and clearing cache fixes it. sometimes it doesn't though.
Help.
EDIT
Never mind. I figured it out. it was night mode that was causing the pink tint via purenexus settings.
title says it all, why is this hidden and can only be accessed thru settings, and it's not a one time toggle, you'd have to go into settings every time you pull your phone out. just why? would be great for the brightness slider to just go to max instead. anyone know if theres any mods for this? or just what this is about, seems strange.

Mine always stays where ever put the slider. But then, I have auto brightness off.
Yeah what version you got? Wish we had outside mode.
I have a 950F exynos 128 GB, and It does not have such setting...
Because it's samsung. They will probably never make a good software. Just search for "automatic brightness bug". They just ignored this problem. No wonder they just hidding that option.
Outdoor mode can be enabled by editing something in system folder. Most of custom firmwares provides that function.
I've never seen that setting on mine. It's automatic for me.

IT is not a bug, and yes, there are ways to increase brightness beyond standard maximum, I remember from the days of my note 3, that many people posted very bad screen burn in and excesive batt drain when changing the lines to attain the most bright screen possible, same applies to speakers, might as well get blown, The auto brightness in note 8, in fact is very well implemented, because it learns your preferences, that is, if set to auto, and you move the slider, whenever the phone detects the same lux level, it will set the level you chose, infact, when in autobrightness, when sensing too much light, it will set an extra ammount of brightness

Agreed. Works very well. Was using GPS Google maps for the first time yesterday, screen was automatically too bright. I used slider to lower brightness, it learned my preference.

Since long I haven't seen any Note device (at least International versions) have Outdoor mode enabled by default unless you are using custom ROM. But this mode i have seen available on low range samsung devices. Actually it is hidden and one minor change in settings app enough to enable outdoor mode.
I will try to make small app without making changes in setting app, though it might needed root access.
Thank you dr ketan! I have used your excellent roms and kernels in my note 3 and 4

hey something cool came out of this post, awesome!
so the app acts like a toggle to turn on the outdoor mode, pretty cool!
Works perfectly. Thank you.
Have noticed this mod seems to time out after 15 minutes or so. Any workaround for this?
@ dr.Ketan: since updating to oreo your app does not work anymore... do you have a solution?
THX in advance!
I am on oreo too and working fine. Check you have granted su permission
Hello, 3 days ago I bought oppo x3 pro. Phone is awesome, but auto brightness works very bad... It keep decreasing screen brightness to very low level.
I never seen something like that, Samsung S20 works much better, well, even realme x50 works normal. To use phone I had to disable auto brightness. Is there anything like adaptive screen brightness, I read somewhere that samsung by the time learn my preferences, and keep good brightness. Tired this with oppo for 3 days, but seems it doesn't have that option.

If it is the same mechanism as in OnePlus (not sure about it) - then the phone will "learn" after you manually set the brightness to proper level. Give it 2 weeks.
Btw. Rydzyk in avatar, hope youre not the real one
Real Tadeusz here
I was teaching for 3 days, but without success. Will try for a week now

Try clearing system cache and data in the relevant apks.
Test the light level sensor to see if it falls within an acceptable range.
I use manual brightness control almost always; doing so saves battery, retinas and sanity.
It also reminds you when it's too bright and your frying your display.
Same here. Helped me out with Lux Brightness and set the minimum brightness to 30. Works fine for me.
To me in Realme 8 it seems to have learn a minimum value for auto brightness instantly, I just set a minimum a little above of the default level (It was very low), and the phone remember that level onwards
well, mine surely isn't 'learning', it keeps defaulting to the lowest value, which is waaay to low.
Are there any alternatives to Lux Brightness that you know off?

What happens to me is that the default auto brightness deactivates itself when it wants, and reactivates also when it wants, very annoying. So I deactivated manually the auto brightness and tried Velis Auto Brightness, this app is a little complicated but works quite well, just you have first to understand the app itself and then tweak a little to your convenience. It has a little bug in Android 11, the notification of lux and % of brightness screen disappears after some time but doesn't affect the app itself.
