I was trying to lower the brightness very low to test how it would affect battery drain and it seems that the phone won't let 3rd party apps lower the brightness lower than what you can set it to, in the phone's settings. I tried an app called timerrific that lets you schedule various settings changes, but the phone seems to be overriding it. When I set the brightness to go down to 15% via the app, it does go very dim, but then immediately bounces back up to lowest level the phone's settings let's you set it at. Also, I had auto brightness off and the power saving mode off.
Has anyone been able to get the phone to go to very low brightness?
Thats a good question and would like the answer too... to me, the lowest brightness which must still HOG the battery as sometimes it seems to drain very fast with usage (and I have it on the lowest setting)... seems overly bright. I would without a doubt use it at a lower brightness to conserve energy depending on what I was doing at the time.
hey maybe its just the screen that makes it look bright

Not sure what you mean? For example, if I set the brightness to go down to 5% through the app Timeriffic, the screen will dim down to where I can barely see anything, but then it immediately raises back up to the lowest setting you can set in the phone's normal settings, which seems to me to be about 25-30%.
Yep

This is actually correct, the screen is what makes the "Automatic" brightness setting on the SGS phones look brighter than their LCD brethren. As we all know, currently all AMOLED displays use some kind of Pentile Matrix. All HTC devices (The N1 included) currently use RG:BG Pentile Matrix.
Do a google search on: "RGBG Pentile" and Samsung's site details it.
The SAMOLED display Samsung has made uses a new Pentile Matrix called RGBW:
Do a google search on: "nouvoyance" and it's the first site (sorry for the odd instructions, won't let new users post links )
Using the new RGBW, a white subpixel is introduced on top of the standard RGB stripe. From my reading, this allows the screen to achieve the same resolution to the eye with 33% less subpixels and is a brighter display in the process.

Good explanation, but are saying that no you can't dim it to low levels because it makes it look brighter than it is? If so, I don't buy it. I see it being dimmed to a low level. It just doesn't stay there.
Aldiko reader can get the screen even more dim

Also since there is less air gap in the new display, it is brighter.

This is just me speculating, but I'm thinking maybe the brightness setting is universal to android devices, except that it's calibrated to normal lcd. So the same voltage(or however they regulate the display brightness) on an LCD will look brighter on the Super AMOLED. For me, the dim setting on the auto-brightness seems too bright.
One thing I've noticed is I can take the brightness down to its lowest setting and it still seems bright..however on almost every phone I've used its like this.
The weird thing is on the Captivate I can open the browser, men then scroll down to settings and it has a brightness toggle there that takes it lower.

Yeah that does take it down lower than the home screen by a small amount. I put the browser brightness on the lowest setting and the global brightness on the lowest. Both auto brightness and power save are off. When I switch from the browser to the home screen, it brightens up a touch. So, it does go lower, but not all that much though, and it's only for the browser.

You can totally dim it more. In doing so, it will use even less power than an LCD screen at the same brightness setting.

Yeah, that's what I thought was cool about this type of screen, but I still don't know how to to dim it below the the lowest setting in the phone's control panel (which isn't very low). 3rd party apps I've tried don't really work, or they work, but the phone immediately raises it back up. Are you saying you've dimmed it down to where you can barley see the screen, like 5-10 percent? That's what I'm looking for confirmation on. If so, what app did you use?

I have used this app and seems to be pretty good, makes the brightness lower than system brightness.

i use brightness level too but the brightness goes back to the highest level when you plug the phone in and you cant use the presets on the widget anymore

I tried this app, and while it's a good app, it still doesn't make the screen go super dim. It looks to me like the lowest level (0%) is the same as lowest setting from the control panel. Zero percent should really be totally black.
Screen Filter
Here is your 100% working solution.
It doesn't work with the bright level, it applies a shade/filter to the screen. No matter what app you're using.
Set the bright to the lowest with your default system settings, because if you use a third party that goes below normal, with some apps like explorer, it set it to minimum allowed be system or whatever you set and then you will notice a setp up, shaded but a change.
I'm using it weeks ago and I found it's the best choice to suft the web at night. Also you can turn off softkeys lights

flash speedmods new kernel.
I've looked around and haven't found much, hopefully my Google skills aren't weak.
Other than using a screen dinner app, is there a way to actually decrease the backlight further? I can do some more complicated stuff like decompiling apks and what not. I just don't know if there's a way to make the range of auto brightness much lower.
I use my phone a lot at night, and turning the screen on is like getting punched in the eyes, andwhile I'm using it I feel my eyes strained.

try an app called lux. Its not free, but it did wonders for my battery life
Another option is JuiceDefender Ultimate... you can tweak the response curve to obtain lower brightness levels in low light conditions... it has a ton of options.
free app called screen filter, does what juice defender does, but its free. and it goes REALLY low .... to the point you will see "blots" of dots on the screen

Screen Filter just puts a filter over what your phone is displaying instead of actually physically lowering the backlight. It makes things look odd (to me) and it doesn't actually do anything for battery life unless I'm mistaken.
I mean something that actually allows you to lower the backlight further.
technically speaking becuz it's putting a software overlay on, the phone physically uses less power, so they do work. You lose some contrast between certain greys and farms though. I highly recommend u look into the "Lux" paid app I was telling u about. Its the way auto brightness should be, with user accessible custom config. The author is so good that if at anytime u decide the software isn't for u, u get a full refund, no questions asked, even if its a month after, let alone a couple minutes past the 15 min return period

I'm not sure what you meant by becuz it's putting a software overlay.
I have realized that having the screen darker (even just displaying a darker image, like what Screen Filter does) uses less power because of the way that our screen works. On an LCD screen however, it would actually use more power.
I'm trying lux out right now, it seems promising.
when you use the term "physically" i take it as you want a PHYSICAL mod to the phone; good luck with that. Screen filter does me just fine, it does the same effect as many other "battery savers" do.
any apks, apps, etc are all SOFTWARE mod to the display screen / brightness. You are venturing into a world of unknown if the apps aren't appealing to your taste.
Keep in mind, the SR is S AMOLED, not just a regular LED / LCD display.

No. By physically lowering the brightness of the backlight I meant that....well the intensity of the backlight is actually physically lower as opposed to seeing everything through a grey mist (how I see the screen filter thing).
Also, try to contribute to the purpose of this thread instead of insisting screen filter is good when I've specified that's not the solution I'm looking for.
Speaking of useful contributions to the thread..
Lux is really nice. I like it. I can't tell if the sub zero brightness is the backlight actually being PHYSICALLY (by means of software, don't worry) less bright or if it is using a filter where I just can't tell. Either way, if I can't tell then it's not bugging me. Thanks for the tip, after a day of setting it up and whatnot it's really nice.

.uhm.... don't be decieved by the name "screen filter" ; that is just the given name; the method of adjusting brightness remains the same as many other "filters" and "brightness" controllers.
Searched "lux" on the market and a lot of them have poor reviews, screen filter has over 9,000 5-star reviews so I'm pretty sure it's working...
You try screen filter and drop that "filter" below 20%; so if it's not the "brightness" being adjusted? what is being adjusted? color? gamma? contrast? sharpness? color intensity?
Again, I'll let the reviews speak for themselves; my main point is, SOFTWARE = SOFTWARE. Android is the system; the software manipulates the settings of the system... so unless Lux is somehow hacking unknown system values / physical hardware, software = software.
Another vote for screen filter by me. Period.

I'm glad that you are using the reviews for random apps with the name lux in them as grounds for proving your point. Just in case if you care (which I doubt given your hostility) the app that I'm using is Lux Auto Brightness. Very nice.
Oh, and don't worry. The reviews give it a 4.4, not as good as screen filter but that doesn't seem to me to fall under 'poor reviews'.
Again, I wanted to lower the BACKLIGHT. Which, in turn, means a lower brightness. I wanted an app that would allow me to decrease the physical brightness of the backlight. How can you not understand this? Screen Filter does not do this, it puts a filter over the screen.
It even says, right in the description for Screen Filter "Applies a shade that acts as a dimmer to ensure your eyes don't hurt."
That is NOT WHAT I WANT.
Lux Auto Brightness actually does what I wanted - it allowed me to lower the backlight even further, making my phone less bright WITHOUT putting a filter/shade/softwarewhatever over the STDOUT. Goodness.
Also, thank you for specifying that software = software, I have no idea what kind of mess I would have gotten into without knowing that.
I use a very dim display to save battery on the Surface or any other mobile device. The adaptive (auto) brightness feature isn't truly the best for the Surface for sure. I noticed that the screen flicks too much even though you're in the same environment. On reading about it on the web, I figured that this is a genuine problem for many on the tablet. Bad design maybe. So instead of reducing the brightness to minimum, I kept it at almost like 7-10% and voila ! The display is now as crisp as its supposed to be ! I wouldn't guarantee if it won't flick at all, but trust me, its like 90% better
Enjoy your new Surface !
screen flickering
Hi,
I've also noted some light flickering issues on my Surface (that I really like) even if the auto-brightness feature is off and with 100% level.
Generally speaking, it's not visible unless :
- you're scrolling quickly through the start screen
- you're closing an app with the proper gesture
It seems that for half second the scrim flickers...is it also happening to you ?
I was considering a RMA but I'm not sure if it's more a SW problem than a HW one.
Thank you for your answer.
Fabio

I think its more visible when you're on the Metro UI or the Start screen. And more on when I am scrolling from the side of the screen, just like you said. Its pretty weird.
I have read articles that said using DC brightness on OLED/AMOLED screens can effect colors, particularly at low brightness. How are people finding it? I dont really care if it makes colours "less accurate" as long as they dont look weird
Looks fine to me. Barely can tell the difference.
Working well as described, couldn't tell the difference.

What makes you think the 3 / 3T screen is capable of DC dimming? Can every AMOLED screen support it?
First off, I don't notice any flickering when the screen brightness is low so maybe DC dimming isn't for me. I'm sure someone with a fancy color monitor device will probably post a technical breakdown of how it affects the screen, but I don't see any difference except in one scenario.
In bed I tend to set the brightness settings on the lowest and then turn on nightmode to dim the screen even further. If you have small white text with a black background such as the settings menu or Youtube in dark mode, some of the text fades into the blackness and is unreadable. Images with dark colors or areas will look weird because you won't be able to distinguish them apart.
I tried to take pictures to show a comparison, but the screen is so dim that it doesn't work.
Hello ,
I observe that, my s22ultra in the same conditions (light intensity) make darker screen than my old note10+.
In my old phone (note 10+), the adaptive brightness works very well for my eyes (maybe excluding reaction speed - but never it wasn't too bright or too dark (in my opinion), never had to change any settings.
S22Ultra always make's screen too dark for me (in all lighting conditions) and i compare works of with my old note10+ and approved my suspicion that s22u makes screen darker than note10+ in the same conditions.
In general, the "jump / scale" of switching from light to dark and vice versa is good, but I would have to move the "threshold / level 0" action to a slightly brighter - if anyone understands what I mean - you can do something about it, someone has an idea ? Can I fix working of this function ?
What do you think about adaptive brightness in S22U?
Are you satisfied with its functioning?
See the differences compared to your old phone (what mobile it was)?
Thank you very much for any suggestions
I have two N10+'s and as far as I'm concerned adaptive brightness never worked right. Maybe better than my S4. I disable and use manual control, easier on the battery, display and retinas. It also varies in spite of not seeing huge changes in lighting conditions when sitting, I find this very distracting.
Best practice to limit display on in direct sunlight to seconds not minutes. Avoid using in direct sunlight whenever possible.
I try to limit brightness to less than 50%, 30-40% is typical. As a result after almost 3 years of heavy usage my original N10+'s display is still perfect with no signs of wear.
If I know I'll need to use the phone in bright conditions I will temporarily enable auto brightness sometimes. Otherwise I find it useless and generally too bright.
