[Q] backlight control - G Tablet Q&A, Help & Troubleshooting

Is there any way or app to increase the range of
the backlight? I would like to be able to get it
dimmer in a darkish room. TIA

well, I already *knew* about that
What I want is to be able to gain *MORE* control over
the backlight. So to speak, if the present range is 0-100
I would like to be able to set it to -10 and +110 or
something like that.
I doubt that the minimum brightness or maximum brightness
available now is the absolute range limit the hardware
supports.
But I might be wrong

Auto brightness in 2.1

It's either missing for me or I can't find it after updating to 2.1. Any ideas?
They removed it.
My first suggestion would be to use the search function on the forum...

You know, I've seen a million posts just on this forum that say "Auto Brightness is now in the widget" and "Auto Brightness is always on" and now you're the first saying it's gone.

Because if you actually use the widget you will see it isn't "auto" its preset. Off Mid Full.
From what I can see, especially when using outdoors, the brightness level you set in "settings" determines the minimum brightness level.
Whereas, the actual brightness level is equal or higher than the minimum dependent on background light intensity.
Try to test it under sunlight, cover the light sensor then uncover it, should work.
Auto brightness is present. Its on the widget with your wifi settings. The brightness widget has three settings low, auto and high. I have tested it several times and the phone does respond to light and does get brighter. It seems they changed the sense algorithm for it. But it works, just not like it used to.
EDIT:
Here's a quick way to test, if you have desk lamp that's florescent you can set the widget to the the auto setting (second option). Unlock the phone and hold it up close to the light, if done correctly you can even see the text on the phone get gradually brighter. Now quickly cover the sensor and you will see it dim. You can use direct sunlight as well in the same idea.

Exactly. In the auto setting, you can adjust the maximum level in the settings, like it used to work.
To all those saying it's gone:
PUT IT UNDER A LIGHT! It's not that hard to see for yourself
Use the widget, set it so there is no green bar under the brightness, then press it once.. it will then get brighter on its own in bright light

[Q][SOLVED] Too bright display

I'm trying to decrease the screen's brightness as much as possible.
When specifying the brightness in Profiles (apk) the minimum allowed is 7%. Still it's too much for me in certain situations.
I'd prefer to have an option to completely minimize the brightness like in old phones when disabling back lit.
Is it possible with those new AMOLEDs?
Thanks.
I don't know about any other phones, but for our atrix, use an app called superdim from the market. lowers the brightness even more so than normally allowed.
Not exactly the most comfortable way to do. The Profiles should include this feature natively.
Anyway many thanks, it did dim the screen just fine.

Look for rogerpodacter's thread on manually lowering the brightness through terminal emulator. It works great and you can lower brightness of capacitive buttons too. Thing is it if you reboot you gotta redo it but it is not hard.

[Q] Auto brightness for Xperia S?

I've seen that the Xperia S has light ambient sensor, but i cant find the configuration to enable auto screen brightness.
Any idea how can i enable it?
I don't think there is a setting for it there wasn't on my arc either
hmm i have read that the auto brightness function is enabled by default, but i dont notice any brightness changes when i enter to a dark room or go out in the day, auto bright function doesnt seem to work.
Anyone can confirm this?
On my SGS2 with CM9 it is under Settings --> Display --> Brightness.
I dont know where it is under Sony ROMs, but somewhere around Display or Energy Saving maybe it has to be, I couldnt imagine that Sony would take out this...
If you want to test it you could light with a lamp direct in the sensor or cover it, then it has to change the Brightness.
you set the lowest screen brightness you want, then the phone does the rest

not working, just tried. I set my screen brightness to lowest then i put in standby, i went out to the sun and when i turned on the screen and unlocked the device i couldnt see anything.
Also tried with a lamp, doesnt work either

Well, if you manually set the brightness to the lowest setting you are gonna get a dark screen. Obvious thing is obvious.
I've recently been to Sony Mobile's headquarters in Redwood, and I got all the details about this explained to me.
The way it works, is that you can manually set a "preferred level" of brightness, and the phone will automatically vary this setting but not stray too far from it. The default value I believe is 50%.. I don't have exact numbers for how much it will differ, but the auto backlighting is there.
I also asked if Sony will add a manual override to this setting in a future FW upgrade, and they said that they might
SEARCH before you post!!! Already discussed (and how to enable it)
It's enabled via the screen brightess toggle. One option is Auto.

[Q] Improve Maximum Brightness

Hello,
I'm one of those first users who has received GS3 in the first days of June and a user of the FoxHound Rom which is very good since doing some undervolting, modifying the kernel and changing some other setting like free ram modem changing I achieved a very very long battery life (at least +50% of battery life) and a butter like transition as screen effects.
The only problem for me, which would be with every GS3, it's the maximum brightness. It's too low. In the FoxHound mod there's the famous STweak which theoretically has a setting to improbe the maximum brightness from 28 (default) to 35... but I don't think that it works.
Do you know some other root app or some kind of mod which allow a really improvement of maximum brightness? Cuz as default, this display is too dark under the sun, which is one of the the two major defects of this smartphone (the other one is the materials... I'm ok with the chassis made of PC but the backcover made of PC too, no. I'd have rather chose some aluminum alloy or mg alloy with MAO treatment.)
Thanks in advance guys.
Auto brightness is profoundly terrible on the S3.

I guess it will but not much so far.
No guys, wait a moment.
If I'm not wrong, your talking about apps which modify AUTObrightness. But as for that I've already solved just with STweaks which allows to modify autobrightness setting. My concern is for MAXIMUM brightness..Maximum brightness is not modified by autobrightness settings.
As for me lux doesn't change the maximum level.

I`am only interested in the minimum autobrightness values. And this apps solves it for me.
As for minimum value I agree but this doesn't solve at all what I asked in the first post

Uhm ... that's bad ... I mean, what I need is exactely the FoxHound (graphic aosp like, all samsuns built-in apps, downclock and downvolt option on both CPU and GPU, STweaks, kernel like siyah) just with better maximum brightness ... so changing to an aosp rom, I'd prefer to avoid it.
I'm giving a shot to the tone tweak but I don't see any remarkable improvement at the moment...

Where are those modifications to Auto brightness? I don't see anywhere in STweaks where they can be made.
"min_bl" in brightness curve setting.. if you increase it the screen will remain at lower brightness level at higher environment brightness.. practically you change how it reacts to environmental brightness. As for me, it works.
But here you cannot decrease the minimum brightness level.
Any hint?

The screen is way too bright and there's no way to adjust it when outdoors

So when you're outdoors, even if it's overcast there's no way to slide the brightness down (It auto-snaps to full brightness) even though it's not needed.
I have situations where i could easily use half brightness but my phone forces auto max light
YES, I know i can disable auto brightness completely, but that would not be convenient.
Any fix for this?
I use an app called Lux. Tons of options with it.

Hmmmm, Im not sure how it works but it does have an auto mode which you can tweak on the fly.
I have noticed that also. It also jacks up the contrast to make it easier to see.
It makes pics you took look terrible when viewing them outside. I had to learn to NOT delete them until I check them indoors. I assumed some pics I took were crap at first, but it was just the jacked screen contrast that made them look bad.
On my S9+ in bright sunlight it happens that not only something happens to the contrast and colors (eg. reds become somewhat pinkish) but also black elements on screen start flickering/smudging while scrolling. It looks like the device turns into some sort of brightness boost mode.
Does anyone else experience anything like that?

That's exactly what happens to me. Also if you slide the screen you can see how it the colors are totally distorted.

Check out the screenshot. There's an option to enable brightness slider in the notification bar. Becomes easier to adjust brightness just by sliding down the notification bar.

Did you read what the problem is? outdoors it snaps to max no matter what. (Unless not in auto mode)
Any solution for this problem?
Turn off auto brightness when outdoors..
Guys I've noticed that even if you turn off auto brightness go out in the sun and turn the screen up to max manually,it will kick up into super brightness mode or shine a led light at the sensor when indoors simulating the sun,just like it does with auto brightness on.sammy really want us to get burn in I think so we have to buy new screens all the time?

Never had a screen burn in on a Samsung phone. Don't worry
Guys, idk if this is a S10 only feature (or Android Pie), but when I'm on that situation, if I lower the brightness slider and leave it there for a second or two, the brightness will actually stay down and not jump back up again. Worth a try.

After the S9+'s update to Pie some of the old settings get copied to the new OS, but if you don't go into the settings and check, things might not be configured correctly - I had to choose a different setting and then choose again what was previously selected to ensure that it was written into the Settings correctly.
With the new update the "Automatic Brightness" applies to the AOD - see here in this screenshot, my search of the Settings for the word "auto brightness", see what comes up in attachment #1.
What you need to do is go to the "Adaptive Brightness" and turn it on, then manually adjust your brightness under a few different conditions (EG: Indoors lights off, outside and overcast, and bright sunny day). Now your phone will understand what setting you want for different conditions and automatically adjust the brightness based on lighting conditions, see attachment #2.
The "auto brightness" is now used for the AOD, and has nothing to do with brightness when unlocked. The reason it "auto snaps to full brightness" is likely because previous settings were just copied over after the update and you haven't setup (and trained) the new "Adaptive Brightness" for various light levels. The AOD has both "Auto Brightness" and double-tap the clock to adjust AOD brightness.
