Auto Brightness

Has anyone else noticed that the auto brightness is really dark? Especially when compared to my s3 set to auto. Or do I have a messed up tablet?

No auto brightness sucks. You shouldn't use it anyway because it eats battery.

Yep mine sucks too.

How autobrightness works on the magnificent SGN 10.1:
1. Autobrightness ON: when You adjust the slider now You set the minimum brightness that the SGN 10.1 has to achieve. It will never get darker than the adjusted brightness level
2. Autobrightness OFF: set the wished brightness with the slider
It is genious that brightness can be adjusted within one tap ..........

Wow, thanks! This was my one gripe - that autobrightness was too dark in lowlight settings. I had resorted to manually setting brightness, but this is superb! Thanks again.

I don't understand this. Once you click the auto brightness box after doing this it's still too dark. With the box unchecked it does not auto adjust.

Well if you have the box checked you can adjust the lowest allowed brightness with the slider, just try it out in a dark room - Check the box and drag the slider.
With the box unchecked you have to manually adjust the brightness with the slider.

I understand that but with the box checked and level right up its way too dull and althpugh it adjusts automatically, every adjustment it makes is too dull.

Autobrightness drains your battery anyway. Just set your brightness manually. What is it, like 2 clicks?

Chill out bro, auto brightness is the bomb son. More so for phone than tab, but still I find auto on my note 10.1 to be total ****, it's always adjusting itself..to the point where I'm almost having an epileptic fit. I'm now forced to use manual as you suggested. 2 effing clicks, this is an outrage it's 20-12.

Auto-brightness is my only major complaint about this tablet. I have always set my Android phones to Auto and works great. This device it goes as dim as possible & never gets brighter.

Mine definitely does not work like this. I uncheck Auto and set my slider to Max brightness. The screen gets really bright. I then check the Auto box again and the screen goes back to too dim for my current conditions. The slider still shows Max (all the way to the right), though.
Anyway, I don't think working this way would be good, even if it worked. If I set the minimum brightness for where I want it when I'm bed, reading, and all the lights are off, it still won't be bright enough if I'm sitting on the couch, in the afternoon, with just light coming in the windows.
It needs a way to set an Auto Brightness offset or pad value, so you can tell it, for example, make the brightness always be 10 higher than what you would normally set it to.

Auto brightness is seriously off base on this device. Even set to totally bright and auto, it them dims it to an unusable point. Good thing I never use auto anyway.

Seems to work only on the intl 8010 models, not on 8013s. Ive had both, and thats been my experience. Definitely a major improvement on the 8010 and the way autobrightness should work (allow user to set minimum, then scale up from there).

I'm really not getting this. Someone said to check the box and then adjust the slider. Well, the slider doesn't move once I check the box.

When I check the box and then adjust the slider the check in the box goes away.

I can't even do that. The slider doesn't move with the box checked. I have to uncheck the box to move the slider, so I don't understand how this works at all.

I wish auto brightness worked. I prefer to use it on my other devices. Samsung really screwed the pooch. I hope there's a fix. I wonder if they even realize it's broke.

[Request] root brightness control

So, we all know that at the moment one of the main things that kills the battery life is the screen.
I don't know how you feel about it but I think the Z1 is really bright, even when at minimum. If we could lower the brightness beyond the normal controls wouldn't that help with the battery life?

Try lux_autobrightnes,
That app can lower the brightness lower than the system ..

Thanks for that! Sounds like a good app. I will try it and see the effect on the battery life, hopefully it will help.

Seconding the Lux Lite vote: https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite
With it set to Dynamic and Day, in profile editor change:
Lux - 0 = -55
Luma - 1 = -55
and leave all other variables the same.
That seems to give me a good range of brightness for my eyes - readable in bed with no lights on in the room without waking my partner and full brightness in head on daylight.

Hi, I'm looking for a way to decrease the backlight brightness.
Right now even a full black screen lights up my bedroom and I
have the related slider at the minimum with the adaptive setting
turned on. I've tried a few apps but none of them changed the
illumination of blacks.

I've tried that along with a few others. It couldn't dim the backlight beyond what is possible
with the stock brightness slider. After a while it just changes the white point, the blacks
keep glowing the same.

It's physically impossible to reduce the brightness at a Lux of zero beyond what the panel/kernel allow. However you CAN apply a dark filter over the entire screen to simulate the effect of reducing the brightness. This appears to be what Lux Lite and Velis Autobrightness both do.
It works fine for me and when viewing the screen in the dark there is very little light emitted using the settings I stated above. However if you don't make the changes I stated above you won't see the darkening effect.

That's a shame. :\ When my phone is docked it shows a full screen
clock: black background, dark gray digits so any screen filter would
just decrease contrast. I guess I'll need to fix a dark plastic sheet to
the dock to physically cut down the brightness.

I ended up putting a microfiber screen cleaning cloth over the device. It's wrinkle resistant
and big enough so it covers both the front and the back without slipping off. It doesn't look
like it but when near the screen it let's through a surprising amount of light making the
fullscreen clock easily readable. Compatible with all Android versions and doesn't require
rooting.

May I ask, it is possible to dim the three buttons below with Lux?

The kernel allows 4095 brightness steps, I'm not sure what the stock slider does, but I'm pretty sure the lower values aren't even touched.
I started developing a Lux plugin, but ran into a bug with lux itself, I'll try to contact the dev for help.

Guys i have an arc S and just have a small suggestion (not sure it will work on ur device but i dont think there is any harm in doing it)
If u have root
I have created a script to lower my brightness below the actual amount, i didnt use any app from playstore as it actually just placed a black overlay on the screen and the brightness was actually still the same
Well go to my Contributions in my signature and under scripts look at the brightness Adjuster script
Try it
Do not set too low value
I also do not know the default value on ur device so sorry

Screen automatic dimming

Hi guys, using my Nexus 5 I noticed the brightness was very inconsistent, even with auto brightness turned off the screen seems to dim occasionally and then go back to full brightness during use.
Have you noticed it too, and is there any way to stop it from happening? I would really like to be able to enjoy the beautiful screen at full brightness without it going dim randomly, thanks.

Yes I noticed it too, but don't know if it is a software bug or a feature to prevent from overheating (like Samsung devices do) or a hardware problem. It is quite annoying!

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

exactly , it took me 1 min to figure it out yesterday

I have the same issue

That's why I stick to Velis Autobrightness even on Lollipop. Nexus 5 auto brightness is a mess.

Fix for auto brightness? (with root?)

Hey guys. My phone doesn't lower the brightness of the screen, for example, if i go from outside into my house or if i put my hand on the sensor. Is it normal? I think it's bad.
Is there any solution or fix for it that it will lower the brightness?
I tried the xposed module Samsung auto brightness fix for lollipop but it doesn't work.
Hope someboy knows a solution or fix

I didn't know there was a problem

Samsung messed it up with this. I use velis auto brightness app from playstore to overcome this problem.

Sounds like an issue with the sensor in your phone. Mine works, and adjusts the brightness very quickly depending on the ambient light.
