I have been noticing that my auto brightness doesn't work like it did when I first got my phone a few months ago.
Back then it seemed like it changed brightness after a few seconds when it should.
Nowadays it doesn't seem to do that anymore.
Now if I hold my phone close to a bright light, hit the power button and unlock the phone, the screen is very bright, as it should. When I hold my phone in a dark place, it doesn't adjust the brightness. It keeps being very bright.
BUT, if I hold my phone in a dark place and hit the power button and unlock the phone, it's dark, but when I move my phone to a brighter location it does make the screen brighter.
I first thought this had to do with CM, but now on stock froyo it does the same thing.
Is this normal, and am I just mistaken? And should the phone adjust the brightness when I hold my thumb on the sensor thats just right under the power button on the front of the phone (I expect the screen to be less bright)? Because it doesn't do that.
Thanks in advance.
No it's not normal, mine reacts to changes in ambient light in a second or 2 (FRF50), just like yours used to.
When I cover the light sensor with my thumb, the screen dims right down.
Thanks for your reply.
Is there anything I can do to check why this doesn't happen on my phone?
Can I perform a check on the status of my sensor, on it's behavior?
And are there any known reasons why this could happen?
Thanks in advance.
This exact issue is happening with me ever since I updated to 2.2. It worked perfectly before but now I notice that once the screen adjusts to maximum brightness in a well lit area, it never dims....don't know what the problem is. But I hope there is a solution.
Good to hear I'm not the only one with problem, that gives me hope this might be a software issue rather than a non-working sensor.

Actually I may have to take this back, in retrospect, the dimming actually could have been the screen timing out.
When covering the sensor with my thumb and not having the screen set to 15secs, it doesn't dim until I lock/unlock the screen.
Reading on another forum this is by design rather than a flaw, as people complained the screen would fade in and out in certain light conditions... now it can't.
Ah, okay. Good to hear.
Thanks again, Rusty.
froyo seems to fix the autobrightness for me, at least now i can see the screen brightness is changing according to lighting condition, previously i don't notice it (using cyan ROM prior to froyo).
There are some occasions where my screen just isn't bright enough. I turn off auto and set to max. However, when I expose the light sensor to direct sunlight it brightens further. Is there any way to make the screen that bright all the time?

Hi ,
As far as i can remember ,there's a good reason
Samsung"configured" it that way .(you described)
Think in terms of"screen burn in " (Damage to your screen etc )
Not good for your device.
Good luck
Hi there!
First my question - Is there a way to prevent the Note 8 from entering the RED area of the screen brightness slider when in Auto Brightness mode?
Now my reasons for this question, should you care of course
I am a quite devoted Pokemon Go player for over a year now, which has lead to a significant screen burn-in on my previous S7 Edge. Now with Note 8 I am more careful in how I play the game. I have started by making the game run is immersive mode, I tend to deliberately switch between apps to prevent same game elements stay on for too long and finally, I am using the phone with the screen as dim, as possible without causing me difficulties to see it.
HOWEVER, I would like to use Auto Brightness as it actually learns my preferences quite well with one exception - whenever it sees a direct sun beam, it automatically boosts into the red zone, even is the bright light has been there for a second. OK, I admit that the screen brightness is amazing in direct sunlight, staying saturated and crisp and also the system's reaction to a spray of bright light is really fast, except for the fact that...I don't want it.
It's not about saving my battery, I have a 20 000 mAh battery pack always with me. I only want to prevent my screen from burn in and overall degrading faster than normally.
Thanks
I'd like to know this as well.
Same!
i suppose there is memory function, when u drag the slider back to the illumination level of ur choice, it remembers the next time and limits the brightness. some amount of patience is needed till the system 'learns'

Yes indeed, some time is needed for the system to fully learn the preferences
If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
@craige
I think it is intended as you see there's a color RED at the far end of the brightness scale, and that's signifies the most extreme situation the screen can go, which in prolonged use may damage he display. But still, it can provide a elevated readability when you are out under sunlight... And return to safe margins so as to prolong the life of the display...

You posted the same thing on the A50 forum. Which phone are you having the problem on.

I own A50/A70 and checked this and it also seems to happen on S10 !
I am still getting mad of my phone often getting dim/bright ((
ANY SOLUTIONS ? WHAT U ALL GUYS DOING ABOUT IT !?
Hello all, my past 3 AMOLED phones have been facing burn-in where the keyboard is displayed as I tend to chat a lot! Can anyone give me an option to avoid it? Please don't troll and say use less keyboard!
Might help if you keep the brightness on the lower side, other than that seems like catch22
Also choose a darker theme for the keyboard.

That's why it kept happening for me... The I turn it to light mode and then the burn in goes away!
Dark mode will help reduce it, but I leave my phone set to auto switch light and dark mode based on sunrise and sunset, this way whatever app I'm using also switches, so the light and dark apps, flip button colours as well so anything white on a black screen also becomes black on a white screen so it helps reverse any burnin in that sense too.
For example, texting apps usually also have white icons at the top which can burn in with dark mode, so if you switch to light mode, the same icons are now black on a white screen, so the screen burns but the icons don't, so it all slowly burns in together and nothing becomes noticeable.
Been doing this after getting burnin on my S10+ using only darkmode and light icons left burnin. And then on my S20 Ultra I did the flipping light and dark mode and never had issues but I also had the full screen settings to hide the pinhole camera so it made the entire top black, and then One UI 3.0 came out and they removed that option so now you can't hide the pinhole camera and I had a burnin bar across the top from where it was black lol.
Now on my S21 Ultra I have the light and dark mode set to flip at sun rise and sun set, and I can't hide the pin hole so maybe third phone is the charm here and I won't have any burnin at all this time haha.
Hope this helps.
There is no burn in with AMOLEDs; they have a finite lifespan and get dimmer as they age before finally failing after many 10's of thousands hours.
Don't over drive them by using them at maximum or near maximum levels.
High energy blue pixels are the most susceptible to damage, red the least because of its longer wavelength.
Use manual brightness control. Avoid going much over 50%.
Using full brightness reduces pixel lifespan as probably does high temperatures ie direct sunlight.
Limit usage at full brightness by the second*.
Using manual control ensures you're aware of it and keeps the phone from auto jacking it up on you when not really needed.
Turn it down in low light; don't burn out your retina's as they aren't replaceable.
Use dark mode whenever possible. Use dark or black wallpaper. You Good Lock to get rid of the stutus bar icons; simply use the pull down notification screen.
My 10+ gets heavy usage every day with a lot of keyboard time. At 15+ months there is no discernible weakness or dead pixels of any color at any brightness level.
*this is especially important with static images

you say you had burn in from keeping a black bar in the area where the pinhole was?
that doesnt make any sense. If it was black those pixels were off and there wouldnt be any burn in
ಠ_ಠ
Get Gboard, And change it to a dark skin, I've never had any problems

Reverse burn in, the screen area being used has a yellowish tone to it from being worn in over time, no matter how long the display is on, it's always burning in and the colour always adjusts over time from the burn in, it's the image retention burn in that people talk about, but the entire screen is always burning the entire time it's used. So by never using the top area the pixels are fresh and have a cooler tone to them than the rest of the screen as a result of this.

Indeed. And to add, perhaps occasionally change from white to black keyboard to even things out.
This is a good one. Says something about fast charging and not showing this message again. Guess they forgot to check don’t show again.
No offence but:
Pay 1.2K for phone after you see super HDR, huge brightness etc. and then limit everything to minimum? Seriously?
If I see them, I will ask EE(my phone provider) to replace it. I had same issue with OP 7 Pro, screen burn ins, they have replaced phone.

From normal use there will be no burnin. However, if you keep your display on showing the keboard all the time it will burn in. Also pixels start to burn in once they are on

Mate - I had burn ins on my screen from things like clock etc, you cannot get rid of them, and it is a design flown, as long there is nothing in instruction etc.

Samsung shifts the AOD clock to help prevent this. However I use only tap on AOD now.
Perps know the deal, organic LEDs have a finite lifespan. Yeah you can drive your car as fast as it will go but you probably don't because you know it wouldn't last very long.
You wonder why the price tag keeps going up?
Freebies are never free.
Using in direct sunlight or at 80+% is just asking for it. In most cases completely avoidable. One can at least limit the time of use at full brightness and not have a homescreen that looks like a Vegas billboard.

I live in Texas desert, the sun here is intense.
It burns out LED traffic lights all the time; OLEDs are far less tolerant.
Simply use in the shade.
The individual pixels are microscopic. That they work at all is amazing let alone being capable of high lumen output with extremely excellent color/gamma rendering.
The AMOLED matrix has 10's of thousands of active solid state components not just the OLED pixels themselves. All are hest sensitive plus the fact the display is helping to dissipate mobo heat while producing heat of it's own. The most heat sensitive component, the OLED is smack on top of this glass heatsink*.
Direct sunlight in especially high ambient temperatures is a real bad plan. You can fry any display like this.
Know, understand and respect their limitations. You will be rewarded with a long lived gorgeous display.
*glass is a good thermal insulator. Do tempered glass protective screens increase the thermal burden? Most likely. If cool at first the added mass will be protective but once the device (or the sun) heats that mass up things will go down hill from there and the display temperature will rapidly climb.

Common sense should prevail I guess. I live in a place hotter than Spain. If I were to use my device in the middle of the day in bright sun light it’ll cook after 15mins. Hence why I don’t. But then would any other device.
