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.
is there any way at all to disable the screen from dimming on backgrounds with too much white? i think its ridiculous that they built this functionality into the phone without an option to turn it off, is there anyway to tweak the registry? i got the phone because of the screen but if i cant enjoy bright backgrounds n what not theres not much point
There is a option for that. "Screen brightness", switch from Auto to Low/Med/High
no thats not the issue, i have it on high with auto off, yet it still dims when theres too many white pixels on the screen, apparently its built into the samsung driver for the screen, really considering returning it due to this

I immediately noticed this effect when testing an Omnia 7 in a mobile phone shop here in Switzerland and I found that quite annoying.
Try moving from page to page in the Office app. You'll notice a decrease in screen brightness when more white pixels are shown. At least that seems to be how the built-in algorithm works.
I prefer the 4.3" screen of the HTC HD7.
Hi!
It may look strange, but I really would like to keep the screen of the gear watch always on, at the lowest possible light setting and that when the watch detects the wrist movement, the light settings come back to the normal one.
I'm sure this will add up to very low battrey life. But if I can get a day like this, it would be great!
Thanks!
I wanted this at first, because coming from the Pebble -it's just so convenient having the screen accessible all the time and the gesture doesn't always register.My idea was that it should just be a very minimal screen in terms of pixel use to leverage the power saving qualities of the AMOLED tech. Problem is, the AMOLED screen is also known for burn-in on the phones, so I'm afraid even if we set this it would damage the watch screen in the long run (and I would be ok if I only got a day of use also, as I'm fine charging every night anyways).
There is a watchface called "AlwaysWatch" in the Samsung Gear store that's supposed to give you an always on face until the battery runs out. Problem is, it runs as an app instead of the default face and of course I'm afraid to try it due to the burn-in issue. I sent the developer a note saying make the watchface a small, but still legible digital font instead of analog and float the time around the screen periodically would get around this burn-in risk, we'll see if he adds the option.
Thanks for the info on this app (I also have a pebble ).
In order not to burn the screen, it would be preferable to change the watchface form time to time and put it in the lowet light possible...

One of my disappointments besides the flaky gesture wake up is that there doesn't seem to be an ambient light sensor to trigger screen brightness changes. I would have thought that would be a no brainer for a device such as this by now.

Maybe the camera light sensor in the Gear 2 could be used for that purpose?
Recently my screen has started developing strange shadows of apps that i use for longer time, like browsers, keyboard etc.
Even youtube after using for more than an hour or so give shadows on screen.
The issue is more persistent with the keyboard, as i am a heavy internet user (7-8 hrs online) and most of the time keyboard stays on the screen, the screen is showing me a persistent shadow of keyboard, initially just after using it for more than an hour the shadow is very clear and it stays even in the brightest apps and screens , later after sometime it starts to fade but never really goes away, its there always faintly.
What should I do?
Attached screenshots but i don't know if you guys can see them or not.
Edit : its on the screen (hardware)as screenshots don't have shadows, don't know if my screen is faulty
Screenshots are no good, take a picture of the physical phone screen instead.
Screen Burn-in Tool could help, it's designed for AMOLED, but it might end up having the same effect, and there should be no risk (except maybe some wasted time ).

Thanks but i think its better to get the screen replaced because the burn-in tool is a temporary solution, it again comes up after few hours and usually goes away in the morning as i don't use phone at night..
Also screen flickering is visible on very close inspection of some dark screens and checkered wallpapers
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.
