Question about auto-brightness

I don't really see a difference in brightness between auto-brightness and manual on lowest setting. I tried changing lighting conditions of the room, even covering up the light sensor with my hand to see if it changed. I still didn't notice any change. Is the change supposed to be dramatic and noticeable or very subtle? My girlfriends Incredible has a very obvious shift in brightness when auto-brightness is available, I don't see any on my NS.
Is there an app or way to test to see if my ambient light sensor is even working properly?
BTW im running CM7 RC4 with Netarchy Kernel, although stock 2.3.3 was the same. I'm also using different color profiles, but I don't think that matters.

Increase Screen Brightness beyond normal or "stock" values?

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.

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.

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?

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

minimum brightness too bright?

Hey guys,
Is it just me or the minimum brightness level on OP6 its too bright for the eyes?
I use night mode ofcourse, but still... I would prefer to reduce the brightness a little more. I'm rooted, do I have any good options?

I use auto brightness, but also find it a little bit too bright. I don't have root access, so I just use a screen filter app (https://play.google.com/store/apps/details?id=nu.lower.brightness) to reduce it to 60%. It also helps for the battery life

I have the opposite problem, I find the minimum brightness far too dark. There should be a setting to raise / lower minimum brightness to suit individual needs.

Use this app to set screen brightness below minimum: https://play.google.com/store/apps/details?id=com.haxor&hl=en_US

Even if u use third party app the notification bar is still bright... Is there any way by command prompt
