[Q] Adjusting brightness

Hi all,
Is there any way to reduce screen brightness even lower than what we could do with built-in settings? Thanks.

I'd love to know too. The screen is just a touch too bright in bed at night

I'd like to know this too, I have it at the lowest setting usually and it's still a little bright, I don't even need to turn it up outdoors.

On my modded galaxy s, the darky rom come with an app called "screen filter", it enable you to get your screen WAY dimmer, may be worth a look for in honeycomb, nice for froyo/gingerbread, you even have it in the task menu... my 0.02cents

I noticed that i always have to set it to the max cause it cut down on the glaze. This screen is like a mirror during the day.

try that app (requires root)

AdjBrightness doesn't work. I'm running Modaco ROM HR3, which means it's rooted, but AdjBrightness keeps saying it requires root. Thanks anyway.

Try "Brightness level" by curvefish. I can't guarantee it will work but it works on my g tablet?

I don't think any apps can make it dimmer, without rooting and system access. Brightness level widget doesnt make it any dimmer (it reports the brightness level as 8%, when the system brightness bar is all the way to the left, and when set to 0% in BLW the screen doesnt change).

One of the first things that I look for before buying any device is can the screen be set to a low enough brightness. Manufactures often overlook this in their quest to make screens as bright as possible, and in one case I ended up taping a piece of plastic over the screen of an Acer netbook as a filter to get the brightness down low enough to use in a dim room. In the case of the Transformer, I could not try before I bought, but the screen does go down pretty dim.

+1 for Screen Filter. I don't have a TF yet so I haven't tried it but it works great on my SGS and doesn't require root. I suspect it may not work as well on an LCD as on my SAMOLED screen on my phone since it doesn't actually reduce the backlight, but it's still worth a try.

Thanks, screen filter works!

[app] ScreenOff

Hi guys, if you think how the power button will break sometime because it feels so fragile, maybe you want to use this app. I made this app for personal use, but I do want to share with you.
This app basically only make the screen brightness to 0 (zero), and you gotta wait for 10 seconds to let Android call the lock screen.
nb:
if you didn't wait till time out (10 secs), you are still basically locking it manually. that means you have to press the hardware button twice to wake the screen up

Is it possible to change this in a way you can control how bright the screen is? The lowest setting is '12' that i can get and even that is nearly too bright indoors for me
I havent seen an all that does that

You should try an app called LUX. It will allow you to drop the brightness below the standard brightness.

Lux is a pay app and reading description in market says nothing about dimming below stock settings.
Screen adjust otoh actually can lower brightness to zero can also modify color and contrast too. Best of all it's free. Been looking forever for something like this that works in honeycomb as lowest stock brightness is still too bright for nighttime reading for me.

Screen Issues

The colors on the screen are gorgeous and bright, but black text on a white or gray background is actually pretty dim, much dimmer than even my Inspire. Is this just a limitation of the ameoled screen, or do I have a bad phone? Is there any fix if it's typical? Pretty much a deal breaker for me if I can't fix this... Thanks for any help!

Black text on a white background is as plain as night and day for me. Id say check out the store demo to compare. If the demo is better than yours, swap out.

Good call, I'll do that. Out of curiousity, what was your last phone, and have you compared black on white with it? Thanks!

There is a setting under display that says 'anaylize images and adjust screen brightness' to save battery. This is checked by default and was not on the og s2. This is also separate from the auto adjust brightness to ambient light. I found that when i unclicked this, all my screen concerns went away.

Thanks! That was driving me crazy. It was very prevalent in the stock email app. I can't believe I overlooked that stupid box...lol.

Where is this setting I don't see it in display. The white and black drives me crazy with this phone.

Settings>Display>Auto adjust screen power. Uncheck that box.
It will put a little more drain on your battery, but it's more than worth it, and hardly noticeable to me.

Thanks.. Still seems like the colors are off compared to the Epic.

Anyone have this auto brightness issue?

I noticed that my auto brightness will adjust and get bright when I turn on a light but then immediately when I turn the light off the brightness doesn't go back down. Anyone else have this? I'm guessing it's software?
Sent from my SM-G920V using XDA Free mobile app

Yes. I play with that by keeping my s6 under the lamp. Super high brightness levels.

I was just about to make this thread when I noticed yours.
Actually for me, I get low brightness levels it's very annoying. When I'm in moderate lighting conditions like normal lit room I get almost lowest brightness, when I move phone out in the open area, like outside, the screen lights up like it should, but in moderate lighting contitions it is very bothersome to have lowest brightness.
I'm now thinking of searching a good auto-brightness app. Any suggestions?

I cannot say any specific reproduction steps, but it looks like I have similar problems..
Galaxy S6 is my first Samsung device ever (before M9 I was HTC fan). Comparing experience with other devices I had - auto-brightness works definitely in a strange way.
Under direct lamp light - it's adjusted pretty much okay, but in a normally lit room - it's almost always too dark, and I need to adjust auto-brighntess level manually. So.. for me it's really not auto-brightness.
P.S. labas

So any other thoughts?

Same thing here. No solution so far. I tried to install velis from the play store, it is not working. I decided to return my edge emerald green ( ) because of this issue. In a normal lit room I get always low brightness, I have also the S6 flat to compare, side by side, and the S6 flat is almost at the same brightness if I set it at 50% and the edge at 100% (both in manual setting). Unbelievable!

I have S6 FLAT, and the autobrightness work ok if the phone are horizontal. But if i have the phone in my hand (in an angle more than 10 ° / 20 °) the auto brightnes bright the screen, but when i turn the light off the brightness doesnt back down. But if the phone are horizontal (0° in my hand or in a table, the brightnes bright up and down without problems)

There is a new 5.1.1 minor update available. Has this solved the brightness bug of the s6 edge by chance?

Just little different
I have a s6 flat and my screen is always on full brightness when auto brightness is on.
Tried the light senson and it seems to work fine (0 to 1 lux on dark room, 400 to 600 lux near to a light bulb). This problem started two days ago.

Same, here. Help us out guys.

auto brightness issue
I also got an auto brightness issue on my s6 flat version. Specifically it's about the adapting to low light conditions after being in high light e.g. turning on a bed lamp for a second (screen lights up) and after turning the lamp off s6 stays too bright and does not want to get back to low brightnes. The thing that helps is either lock/unlock the screen which makes it wake up with proper brightness or uncheck/ check the autobrightness box at the bar.
Is it commonly known issue that Samsung knows about or is there any possibility to get it back to normal on my own? It drives me crazy in a flagship device!

I have got the same problem and I'm dead sure it is a sortware issue. I tested the light sensor and it can update on different light conditions no matter the orientation is. I also installed Velis Auto Brightness app and it fixed the issues so Samsung should fix that since 3rd party apps can.

I too have the same issue. The brightness ramps up as its supposed to under bright light but doesnt go down under low light/no light unless i do one of the following:
1) keep my phone horizontal or at angle of >180 degrees
2) lock/unlock the phone by pressing the power button
3) manually tick/untick the auto-brightness check box
Really annoyed. I still under the return period so not really sure its a hardware defect or not

Well, unfortunately I'm facing the same problem :crying:
What are the differences to phones which do not have this issue repectively is there something in common who have this issue.
The biggest changes I've made to the phone are: Arrow Launcher (MS) and radiant theme (no root etc.)

I got the same problem, autobrightness adjust only when phone is placed horizontally. Any news in this regard?

unfortunately no

Do you still have this issue? Because I have it on every single ROM, Custom or Stock, no mather...

I have found the max_brightness adjustment, (sys/class/backlight/panel/max_brightness) but I can't find a similar file for minimum brightness. Anyone know it's location? At the moment I'm using a third party app as well, but would rather have the system fix.

Question about screen dimming

It is clear that your mobile phone has a technical problem that needs maintenance, but try to return it to factory settings

On the Flip 4 I use the Adaptive Brightness "on" setting, and Dark Mode. Your results may vary, but here's what I've seen.
In the summer, on a sunny day, I'll notice that the phone will automatically try to be as bright as possible, so the screen is readable. (I'm pretty sure when this happens the quick display panel's screen brightness slider color changes to orange. Maybe the color depends on the wallpaper/color palette.) And I never see the screen do this "extra bright" thing indoors. Only outside and only in direct sunshine.
So far so good. I think this is as everyone expects the phone to operate.
Given all this, sometimes I'll notice the screen brightness will vary, even though I'm still outside and still in the same brilliant sunshine. I've noticed this commonly when checking Google News, and for example, I'm reading a story and scrolling slowly through the article. In particular when the screen is mostly black text on a white background.
So, in this situation, that is, a largely bright background, in the bright sun, my phone will both:
Get warm to the touch, on the back-side of the phone, where the two batteries are, but not up where the cameras, CPU and memory are located. This makes sense because "scrolling text" isn't that demanding on the CPU, but I am driving the OLED screen hard.
Also the front of the phone (the OLED screen itself) can feel warm. Even in the screen's crease, away from the battery. Since the image is mostly white, all the OLED dots are "on" and give off heat. Then again, I'm in brilliant sunshine and almost any surface will get warm.
Further, I'll notice that the phone screen will automatically get dimmer after a bit of time (perhaps a minute or two of extra-bright before the dimming). This I attribute to the software doing one, or both of:
Dialing back the screen brightness, to prevent OLED burn-in.
Dialing down the power usage by the screen, to prolong battery life and/or limit the battery temperature.
What's more, after little more time, still in the same bright lighting conditions, perhaps reading the same story, the screen might be noticeably extra-bright again. It's as if the phone has given the display "a rest" and is willing to go "extra bright" again.
In short, I think the phone screen is trying hard to be brilliant in the brightest of sunshine. But there are limits in how hard you can drive an OLED screen, and how long the battery can power the screen.
All of this before we start to talk about what design limits come into effect when the CPU or graphics processing come into play, both or which compete for:
Power from the battery, and
The ability of the phone to keep itself cool.
This phone's form-factor is all about folding in half. A slab form-factor phone, I suspect, will be far more capable for heavy CPU, graphics, and provide a bigger battery and better heat disipation.
