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

I really love my Inspire, especially w/ Honeyogen installed. But the problem of viewing the screen in direct sunlight is a major problem for me, one that I cant seem to find a soultion for.
Ive tried different screen covers & different ROMs & even different Kernals, yet the Inspires Slcd screen is still terrible in direct sunlight, as all I see is my reflection.
My question is this... is there anyway to hack the screen to increase the brightness beyond the "normal" or "stock" brightness levels?
I would think that if developers can hack volume levels for the external speaker & also freq values for overclocking the cpu, that the same could be possible for the screen brightness!?
Thanks, i appreciate your thoughts!

Thank you for this question. I am interested in a solution to this as well.
is your screen on auto brightness? take it off and adjust yourself. it will adjust to light depending on how much and how little you get.
If your rom is cm7 base go to menu, settings,cyanogenmod settings,display, automatic backlight,scroll down to light levels,check use custom, other levels, (this is what I do) change 1st 3 screen profiles from 41 to 61, 61 to 81, 81 to 101, then hit save and apply. The higher the # the brighter the screen. Those settings are pretty good on battery and definitely helps on making the screen more viewable outside and in bright rooms. Hour this helps

Thanks for trying, but of course I've set my brightness levels myself. Auto-brightness doesn't do it for me.
I'm just surprised that there aren't hacks for screen brightness. Just as speakers levels & the CPU are governed to a certain threshold in stock configs, I would think the screen is governed and has much higher brightness levels it can go beyond.

Yes, my ROM is CM7 based. But I assume these custom levels are for the Auto-Brightness mode?
Also, where exactly do I make these changes? Because the "screen" values are already at 41, 61, 81, 112 and so forth. So I assume these values have been changed by my ROM developer or are they CM7 defaults? Or do I have it all wrong? LOL. Thanks again.

Yes, this is for auto brightness. You do have the correct defaults. I bumped the first 3 profiles up by 20 and screen is brighter at lower levels.

Ok, but my question is does this actually make the screen any brighter than the highest stock brightness level?
Or does this just change the values, so that the lower values are brighter, but no brighter than the stock highest level?
no brighter than brightest stock value
Sent from my Inspire 4G using XDA App
So why can you developers increase & hack the speaker and the CPU values and MAX out their potential, yet the screen's potential is wasted and we are stuck with dark screens that can't be seen very well outdoors?
It doesn't make sense to me. The screen backlight must have more potential, they don't push ANY hardware to it's max in stock configurations.
Come on developers, we need you again!
FALSE - juice defender's ultimate (maybe even pro) app can adjust it higher than the 100% brightness value. Only problem with this is that you have to let it control your brightness settings, but there's a bug that doesn't allow you to install apk's manually - so you have to disable the brightness while you install apks (or you could just install through adb lol). so yes, there is a way.

Um no Juicedefender does'nt raise the screen brightness ANY higher than you normally can w/ the stock brightness slider. All that does is mess with the Auto-Brightness settings.
Alot of people seem to get the Auto-Brightness settings confused with what I am asking. I want to be able to raise the brightness beyond the MANUAL brightness slider. If you raise the auto-brightness setting, your STILL limited to the max value that's on the manual brightness slider. I want THAT manual setting to be pushed beyond the normal "stock" value, which I guess is impossible......can't understand why when almost every other hardware is hacked to allow better performance.

Okay sorry just looked at juice defender again. It allows you to only change the shape of the brightness curve. As for forcing a brighter screen level I'm blank on that. Have you manually set it to 100% and its still. Not bright enough?

You cant overclock the values of your android hardware "screen" for brightness and dimness since it can only work properly on a given threshold hence any more than that is negligible.
i was wondering if there was a value somewhere that i can change to lower the minimum brightness level. i dont use auto brightness. i just want to make my screen go even dimmer than currently possible. the lowest level is really not that dark. it still hurts my eyes when i look at it when i wake up in the morning. i also saw that my friends iphone's screen goes way darker than mine. thanks in advance
Hi guys,
I have a cheap Chinese Cube T8Plus that I use exclusively to read comics and books at night.
It works really well for that use, but has 2 very annoying problems with backlight brightness that makes it less than ideal for low light use:
- with manual brightness, the minimum brightness is very high, and even with root and a software like brightness tweak, it stays the same (I can actually increase the minimum brightness, but not decrease it).
- with auto brightness, surprisingly on low light the screen gets a lot dimmer than with manual brightness, it makes a huge difference. But here too there is a big problem; the brightness does increase whenever I the tablet is exposed to higher light, but doesn't decrease back on low light, no matter what I do.
The only way to reset it back is to fully reboot the tablet.
I tried different roms to try fixing the issue, they all have the same behavior sadly.
Of course I know there are screen filter solutions like the twilight app, which I actually use, but it's not always enough, and kills the contrast a little bit too much sometimes.
So is there any other way to force the manual brightness to go lower, that might work for me?
If not can I override the auto brightness in some way?
Thanks
I don't want "daddy Samsung" to decide when my phone can reach maximum brightness or not [even if it is to protect my eyes or save battery etc..].
So, how do I enable my phone [in any way nessecary] so that I can manually adjust it to maximum/peak brightness via the slider, without being in sunlight?
With "unlock" do you mean to root it?

Let's just use the word "enable" [in any way necessary]. I'm willing to root if need be, but in that case I would like to know which mods/kernels etc that can make this happen

What is wrong with disabling auto brightness in Settings and using the slider manually to maximise the brightness? Or do I understand your issue wrongly?

Most modern phones won't reach peak brightness unless they are in direct sunligt (by the light sensor). The slider at maximum brightness isn't really the phone's peak brightness. The slider is "capped" unless one modifies it somehow (the idea is to protect one's eyes, save battery life etc...).
For example, on gsmarena the specs for the S23's display are: "1200 nits (HBM), 1750 nits (peak)".
So, the slider only brings the phone's display to 1200 nits, while the display's full capacity is actually 1750 nits.
