Brightness lower limit?

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

Screen brightness "jumpings" ?

Guys, i noticed that screen brightnes is always changing, it`s getting a little bit darker and then changing again to a more light, this is really annoying, auto-brightness is off, brightness level is on max, what is this, anybody knows ? And how can i fix that ? I`m on 5.0 with root.

By autobrightness, you mean Adaptive brightness? or is there a 2nd setting I'm not aware of?
...and is it in a particular app? Some browsers etc have their own built in autobrightness

No, autobrightness is off, i set brightness manually on maximum, but the brightness is always changing a little bit, i don`t know, maybe bacuase of the device temperature or something ? It become more darker and then more lighter, just a little bit but i can see this, and it`s all the time.

In lollilop it's not autobrightness , it's Adaptive brightness... and you have to turn it off after the update

Yep. And changing the slider manually only seems to change the minimum brightness that adaptive brightness will go to, unless you turn it off

Screen brightness

Hello everyone,
I noticed that after updating my Mate 8 to Android 7, my screen seems to have an Auto brightness functionality going on, even though I've turned auto-brightness off.
For example, when my screen is in direct sunlight, I notice that my apps are brighter, and when I cover my light sensor they become darker even though my brightness is set to max all the time.
Anyone know why this happens?

There is an option in developer options
Please check the screenshot.
Increase visibility under sunlight
Check if this option is turned on. If it is on then switch it off and see if your problem is resolved. :good:

Hey, thanks! I didn't know that option was there.
I've turned it off now, and I'll see if this fixes my issue.

Need help (Always on dimming)

Hey guys,
I was hoping a few people here could do a quick test for me. On my watch (Gear S3 Frontier non-LTE), I have noticed a difference in the dimming depending on the brightness set.
Basically, if you set a brightness level of 1 OR 2, and turn always-on display ON, I have noticed that when the always-on kicks in, the watch also significantly dims itself.
As soon as you set a brightness level of 3 or higher, the always-on display kicks in but does not dim itself at all.
Can anyone else try this and let me know if you get the same results? Basically, does your always on get significantly dimmer when using the 1 or 2 brightness level, and does your always-on seem to not dim at all after switching the brightness to 3 or higher?
Thanks!

Yea that happens: https://forum.xda-developers.com/gear-s3/help/automatic-low-brightness-t3540063 . I never set my brightness to 1 or 2 tho. I always keep it at 5. So not sure about that.

I'm not talking about the auto-low brightness. This happens whether or not this setting is on, for me at least.

my suggestion is to keep brightness at 3-4-5 and then install the app "theater mode". When you're inside and don't need too much brightness just tap on the Theater Mode widget so the whole thing gets dim. When you're out tap it again, and the watch goes back to the brightness (3-4-5 depending on what you set).

Question Screen brightness

I understand that the P7P is supposed to have a brighter screen then my retired P6P. Yesterday, I had my P7P in the car holder on a sunny day. Even at 100% brightness with adaptive brightness turned off the screen was hard to see.
Anyone else having a problem seeing the screen when outside?
Do you have adaptive brightness on or off?
In Exkm, I see a display option for High Brightness Mode (HBM) which I will try the next time.
I understand at high brightness that power consumption is also very high.
Any thoughts on seeing the screen when outside on a sunny day?

You have to turn it on, unless its max is only at 1000 nits, not 1500 like with Adaptive Brightness.

Turn the adaptive brightness on, you can get 1500nits brightness.
But it drains the battery really fast.

Just an FYI, you won't see 1,500 nits just by turning on the adaptive brightness on. Picture a screen with a white box in the middle and a black background.
Let's say that whitebox takes up 1% of the entire screen and black takes up 99%. The screen might boost that white box to 1500 nits (at maximum brightness slider). So it looks really bright.
Now let's say you expand that box and it takes up 20% of the screen and 80% is black. The screen is going to lower the brightness maybe down to 1000 nits.. even though the slider is still at 100%.
Then let's say you expand the box all the way, takes 100% of the screen, it's all white. The screen automatically lowers the brightness down to 800 nits, even though again the slider is at 100%.

The main apps that I want to see during the day while driving are Maps and Waze. Light mode seems better than Dark mode, but it was still hard to see the maps even at 100% brightness.

Velis Auto Brightness looks interesting. Are you running it on the P7P?
Did you turn off the built in Adaptive brightness?
Can you use high brightness mode with Velis?

I would be absolutely shocked if Velis can engage "high brightness mode".
If you cannot engage "high brightness mode" by turning off auto-brightness and moving the slider bar all the way to the right, then Velis probably can't do it either.
"High brightness mode" is typically only available via stock Auto Brightness or via rooted options.
It only comes on under special circumstances and you cannot leave it at "high brightness mode" for as long as you want (without using root options).

That doesn't seem right, this screen is brighter than my pixel 6 pro at 100% and easier to read outside. HBM you mentioned doesn't seem to work with EXKM and HBM, or at least for me it doesn't, and have set all the permissions and given it root access. There is a difference but it is so tiny it might as well not be there, and my screen is 75% normal when testing.
