Hi all! I'm in need of your help. I use a Galaxy Tab S 8.4 as a ground station for a drone and would like to set the screen brightness to the maximum level when I fly, like the brightness you get when you shine a bright light into the sensor. Is rooting the device with Kingo and then installing the CZ brightness app the only option?

Well the autobrightness wasn't working as I wanted it to. Never had issues with it before on other devices.
So I downloaded Velis auto brightness
I noticed the sharp brightness sensor was sometimes juming between 2 values like 552 lux and 12 lux causing a constant change off brightness. (flikkering)
Could someone check the brightness sensor, and check if it also fluctuate? My S3 keeps steady values...
I had a faulty pro8.4 (dead pixels) on the first day and the auto focus was also not working properly.So I would like to know wheter I have an other faulty tablet or it is just the sensor that reacts differently.
thanks in advance
I have noticed the same thing. When I am scrolling through a website I notice the flickering brightness. I ended up turning the auto brightness off.
My auto brightness just doesn't seem to work at all. It just defaults to lowest brightness. Funny thing is it worked on first boot, but stopped after the very first time I turned the screen off then back on.

I installed CM today and using auto brightness, I can confirm it just goes up and down, dim-bright-dim-bright. It's disappointing that such a nice tablet has a piss-poor brightness sensor.
From my Pro Tab 8.4
My Lux values were all over the place too. Luckily there's an application on the Play Store called Lux which fixes everything. Just set it to adaptive. That's what worked for me.

Can you go to Settings >> Display >> Brightness and then click the settings icon and then the Adjust button. That should tell you the value of the sensor as seen by CM.
Does it really fluctuate there? If so, can you maybe take a quick video so I can see what you are seeing?
I'm pretty sure this is a hardware issue. My sensor flips +/-1 when I leave the tablet sitting there. Covering the sensor drops in down to about 0 and then it bounces right back to the same value when I uncover the sensor.

Wow Thanks so much for suggesting the Lux app. The stock auto brightness jitter was driving me crazy, especially when scrolling around in the playstore.
On a side note, samsung screens are hella bright when viewing at night. Going to put Lux on my phone too lol.
A autobrightness mod I use on my Nexus 10 is the XPosed framework and Gravity box module. Your can set the brightness and lux pair values then reboot. On my Nexus 10 it took three days (night/day) conditions of tuning values until I found the sweet spot. It was not too much of a bother and I've not had to make any adjustments since. Look in Gravity box for display tweaks then all settings can be modified but the pair values mentioned above are under autobrightness levels.

Just wondering if anyone usues lux auto brightness and if there are profiles specifically for the galaxy s6. Any input is welcome.
I use it. Seems to be more accurate that the built in auto brightness. And as for profiles just make them to your liking. Only down side is that it will have to be turned off to grabt apps root permission.
Hi guys,
Does anyone's screen tone change markedly when they take their tab out into the bright sunlight? The screen tone seems to change completely to a more washed out picture. You can actually see the screen change as you move from a lower light into a bright sunlight.
I notice that this only happens when the screen brightness is set to "auto". If you toggle auto on/off in the bright sunlight you can see the screen tone change.
Has anyone else noticed this? Is there any way of changing this behaviour on "auto brightness"? I like to leave my screen on auto brightness but not if the screen washes out...

Most likely it`s the Adaptive display set to Auto, you can manualy make your own selection in settings/device/display/screen mode.
Also try the auto adjust screen tone in the same screen mode section.

It happens irrespective of the screen mode (adaptive, basic etc)
It only happens when I'm outside in bright sunlight and display brightness is set to auto. If I turn off auto and set brightness to max it looks normal.
Have you seen this behaviour?

I dont use my 10.5" outdoors, phones/tablets are hard to see the screen outdoors so i dont bother, just answer calls on my phone nothing else.
You Tab will eat the battery outdoors as it will have the brightness set to 100% so you can see the display, try and find some cover/shade before using it.

I appreciate that you don't use your tablet outdoors and I also appreciate the advice on changing my lifestyle to suit my tablet use but I live in a country where we spend the majority of our days outside near pools in bright sunlight and I'd like to use my tablet in these conditions without losing screen quality & colours. I'm well aware the screen will consume more juice but that's why I've got a portable usb battery charger.
I am just asking if anyone else has noticed this behaviour...

I have seen this! Yes the colors are werid in sunlight. Its not what you normally see. This happens because of how samsung wants the screen to be visible in direct sunlight. Its like the max brightness amoled can go on auto. Meanwhile if you set it manually to the highest brightness, the colors are normal. Its a feature from samsung in which why it looks werid in direct sunlight on auto.
(Most amoled devices have this too like the S6. Putting the device in direct sunlight with auto brightness enabled maxes out the colors and brightness to live with the claim of how samsung says it can be seen in direct sunlight.)

Thank you! I thought this may have been the case... I really don't like the colour representation and tone. Good to know I can change it manually by turning off auto brightness.
Thanks for your response!

Have you tried using a third-party brightness app, something like Lux, it might override Samsung`s outdoor sun mode or whatever.

Lux breaks root. It's not compatible with supersu.

I'll just turn off auto brightness to disable the strange colour effect

Hey guys, I wanted to ask you guys, what is the problem with my Redmi Note 5 AI/Pro after Android 9 update?
I have a rare problem with my Redmi Note 5 AI/Pro/Globle version. The problem is that, my device does not adjust it's screen brightness even it's set to auto brightness control. And the peculiarly is that it goes down automatically if i adjust it to higher level and auto brightness is active but it does not come up even if I go to eclipse.
Mine works but it's still way too dim and reduces automatically after a while even if I force it brighter manually. I thinks it's related to pie adaptive brightness which can't be turned off in miui currently.
There's a magisk module (miui auto brightness) that helps a bit - it limits how dark the phone gets but the behavior is the same.
I've seen more than a couple bug reports related to that on miui forums, maybe they'll fix it.

Same here, have to do it manually.
Auto brightness works fine (brightness slider moving slowly but brightness adjustment is as expected in auto brightness mode)

Android Pie use a different algorithm to adjust brightness, it now encourage you on manual adjust the brightness yourself and AI will try to learn it instead of the old traditional sensor brightness.

Well I don't know what Google did with adoptive brightness or ambiant display but my Redmi Note 5 is just not working with this new feature and I don't know how to go back on to my older settings. This only forces me to every time go and adjust my display brightness manually. The worst thing is that i have to adjust brightness in the bright day light, like when i come out from a dark place and i just want to check any update I can't see my screen at all until I adjust the brightness to up. And to my surprise, sometimes when I scroll down the brightness bar to adjust it to an upper level I can see the bar is on the highest level but screen brightness has been lower from somewhere else, which I can't understand.
Somebody give me any good reason for Xiaomi's new auto screen brightness control system on Xiaomi Redmi Note 5 AI after PEI update, why should I have it on my mobile when I have to adjust the screen brightness manually every time I want to check my mobile for anything. Either it's on #Xiaomi's part or #Google's but I don't want it on my device.
I can confirm that, with the 10.3.1.0.PEIMIXM rom the auto brightness function not working properly, it's horrible!
Hey guys,
So as well know, maximum brightness can only be achieved when "Adaptive Brightness" is turned on, for reason of battery usage, temperature, burning, etc...
As far as I understand, if I stand outside, in the most brightest of suns and set the manual brightness to max, once I'll activate Adaptive, the screen should get even brighter, as the situation requires it.
However, that doesn't seem to happen at all. Am I missing something? Did I not understand how this function works? Is my display just not as bright as the common note display?
Thank you!
I'm in blazing sun and toggle AB on off and screen goes to about 20% brightness ..... ??!??
