The screen auto brightness has always bothered me. I love the convenience of using it but it simply doesn't work like I believe it should.
For example. At night while laying in bed in a completely dark room I'd expect the screen to dim to it's lowest setting. When in actuality it does not, and it always seems to bright. On the other hand when I'm outside in direct sunlight I'd like for the brightness to be at 100%. Again this doesn't appear to be the case.
So what's the issue here? Is there a dev out there who has found a better solution?
I agree with you on this one. The automatic brightness on the EVO is just silly. Its lowest is 25%, by the way. There should be a way to choose what you want the minimum/maximum brightness to be :\
I've seen this question before, some time ago, but still no solution. I've seen someone say use total screen control trial (free in market) and tweak the filter settings to essentially do the dimming value you want.

I have been searching and searching for an answer to this. I don't want to have to use third party programs if I could just change the thresholds myself.
In Calkulins rom he says he lowered the maximum auto brightness to save on battery, and this question has been asked there, with no answer (except for the usual "just use this program to do it").
Someone has to know where the settings for this are. I'm getting more advanced at dealing with apk's, jars, etc... But I haven't been able to find which one controls this. Build.prop has some brightness settings in it, but it's just the default setting when not using auto-brightness (I think).
Anybody ?!?!?!?!?!?!?!?!?
I know it's possible, because Cyanogenmod has the option to tweak the levels in CM Settings.
I just know I've seen an app here on xda, but don't remember what it was.

I know it must be here too but but searching comes up with nothing new. I've tried autobrightness, auto-brightness, with min and max levels, thresholds, custom settings and every other search I could think of.
Maybe I'm leaving out the one keyword that would finnd it... lol

Thanks for looking, but unfortunately I've been there already. It basically allows you to toggle between auto brightness and a variety of static levels, but doesn't affect the min and max of auto brightness when you are in that mode.
I'm trying to be able to leave the phone in auto brightness mode all the time and just have the screen get to it's max available brightness when I'm in a bright area, and minimum available brightness in a dark area.

I did a quick search too, but I couldn't come up with what I saw before. I remember thinking "neat, but I don't need that because it's built into the Rom". It's driving me nuts now too :/
You could always contact one of the devs from CM & find out what files need to be edited.
Basically it sucks. It actually drives to crazy so I just don't use it anymore. When I am on tapa I put the background to black so it's a bit easier on the eyes when I am laying in bed going through the forums before sleep
I customized a luminosity curve for my surface rt, just edit the registry keys.
Download extract and run the attached .reg file and confirm the insertion of the Keys, then reboot the system.
Alert to make a backup of the old keys if you want to restore the previous state.
This change is compatible with all windows 8 but I have tested only on the surface.
Adaptive brightness varies proportionally to the user manual brightness, I suggest to manually adjust the brightness bar to about 20%, if you place the bar at 0 the brightness will be minimal with no automatic adaptation.
Appreciated thanks
New version v2
New improved version.
Try it and tell me if it's okay.
In the zip you will find the normal version and one with more brightness in the dark
I suggest to manually adjust the brightness bar to about 25%
Someone asked me why I did this!
In my surface the luminosity curve does not satisfy me.
The display seemed to have only three levels of brightness, setting an average value (ie on the desk in the room in the morning) adaptivity did not fit values for low-light (night) and lots of light, that is to say the brightness in the dark was not a minimum making it annoying for the view and unnecessary consumption of battery, instead with shaded light levels brightness became easily maximum, with again a waste of battery.
This forced me to move often the brightness bar manually, but now with my calibration does not touch more because it adapts automatically to any light condition.
Also the adaptation of brightness occurred after 3 seconds by the change of light, whereas now changes instantly in 0,1 seconds (100ms).
Awesome, didn't know windows could be modded to do this! On a more related note, isn't the update interval a bit too high? 30x faster than normal seems a bit excessive and the battery drain would be very much more. If it is not too much trouble, could you perhaps make a version that updates every 1 second? This way people can download whichever one suits them best.
Thanks
version 1sec
It is not the refresh rate of the sensor, but the time between changes in display brightness because of lighting conditions.
This parameter does not affect the battery consumption.
However, to keep you happy I attach the version by 1 second.
Tell me if the curve satisfy you in different light conditions.
Thank you, going to try it out now. What do you mean it is the time between changes of brightness? Shouldn't the brightness only change when the sensor detects it? Or is this a filtering via an average for the time period method?
Going to try out both of them to see the differences. Will report back here.
Back!: guess I understand what you are saying, the timing is just the gap between the different brightness levels, not the sensor reading. Sorry for the confusion caused.
I found the 1 sec one to not have a wide enough brightness range, but your original 0.1 sec one works perfectly. Using it now!
Thanks again!
Yes, is the time to change between the different levels of brightness.
1 sec or 0.1 sec, the luminosity curve is the same.
Just for curiosity on what hardware you have tested?
I'm using it on a surface rt. But now I notice in the dark, I can't manually increase brightness anymore. I didn't backup my registry either, but its okay.
Edit: I can edit the brightness manually if I disable the auto brightness under settings
more light night
My intent was never to touch the brightness bar!
In this version, setting the bar more than about 25%, I raised slightly the minimum brightness

On surface 1 just delete the ALRPoints key for the default curve value, on surface 2 I think is the same.

Also doing the restore of your backup, you must delete the key "ALRpoints".

Hi,
is there any way to change brightness to lower level? My previous phone, Xperia Mini, could decrease brightness to absolute black (I didn't need it, but still...). But my Xperia M is still pretty shining in dark even in the lowest level. It burns my eyes. All I could find were some stupid filters. Is there any better solution (root or not, I don't care).
Thanks.

Gravitybox has some brightness abilities to reassign lux-brightness pairs. Don't know if it can go under normal brightness though...
FindYanot: That's exactly what I don't want. I want something on HW level (lower led (or what they use) intensity), not just transparent black layer.
KoenGo: Do you think, it can work? I don't have root yet (I want do it, if I find solution), so I can't try.
Nobody faced this problem? Everyone is happy with light intensity?
Yes it's too much but if you lower that level screen will probably start flickering which is much more annoying than just too bright screen. This is common, hw related issue that can be found on other devices with low quality lcd.
I'm trying but it's kinda hard to tell if there's any difference since you have to reboot after applying new minimum. I would say there isn't much difference. I'll retry in the dark some time.
Doesn't crash or flicker or anything though, so that's the good news
Personally, I would not root just for this and just use the filters. What is your problem with them? That it uses more battery than a hardware method would, or just that it's impractical? In the second case, lux might be worth looking into. I've never tried it myself since it isn't free, I just use the filter u hate
Tried it in the dark and I believe there is a difference, although very small (barely noticeable) and imho definitely not worth rooting and installing framework.
OK. That's bad, but thanks for your time
Well I rooted my phone and I tried gravitybox and I don't think there is a difference. But still thanks.
My setup now is that I can (de)activate the filter app by swiping over the navigationbar. It's still a filter so it doesn't prolong battery life or anything, but it is a convenient way to enable or disable it.
If you would ever come across something better, please let us know

Yes, but you need root.
Execute in Terminal or run attached file as script via Root Explorer / GScript:
Code:
#!/system/bin/sh
su
echo 5 > /sys/class/leds/wled/brightness
Minimal stock value 27, we change it to 5 or any other you want.
Maximum value: 255
Bug: backlight will be flickering.
Thank you. It really works! (I rewrite it manually without any script or terminal)
Just one thing. The brightness file is used for current state and when I change intensity in options (or select auto), it's rewritten. So, is there any way to change minimum level permanently (minimum on bar or 0 lux = 5 or something instead of stock 27)? Or is it possible to make some shortcut to rewrite the file with one click? Or use some tasker for it?
But it doesn't matter much. Even this way, without any shortcuts, is awesome. I'll test it in night, but even now (during a day), I can see a difference.

Yes, but only by editing file in kernel, it requires recompiling.
Then pulled slider to the left will set really minimal value.
Here commit from ElixER kernel for 4.1.2, originally this trick comes from there.

Yes, GScript app, as far I know can create shortcuts.
Or in Tasker create task with only one action "Run shell" (tick Root) and then create shortcut in launcher.

For example galaxy tab 2 (I have one), on the lowest brightnes level it flicker a lot (especially annoying when it's displays white surface), my sister's asus memo pad 7 hd has this issue too but less noticible. Yes, it's somehow related to device's power managment, in galaxy tab 2 forum people saies that it's flicers more when wifi signal is low so as I understand: low signal -> device need more power for wifi -> device gives less power for leds -> screen is more flickering but I could be wrong since I'm almost total electroinc noob I will test that later
p.s.
This issue is really common, even s4 has this problem according to this https://www.youtube.com/watch?v=5yZaQRr76f8 So Sony has done good move with setting so high the lowest brightnes level (at least this hides unusable levels). Really my eyes hurt when I'm using my gtab2 at night although xperia does the same thing but in different way xD
Tested your method and at least in my device, the LED flickering was barely noticeable and only appeared when I set very low values (like 1). Setting as 3 and onwards gives zero flickering here (or I'm just blind, not noticing it)...
You're right. Values about 3, 4, 5 are quite ok.
I made the GSscript shortcut and I¨m finally happy.
I think the flickering is caused by pwr regulation with low frequency. But I'm not electrician either.
any way to edit what's on the ambient display?

So you'd like to see ambient display start but only run for a set amount of time? I know I've seen it get really dim, dimmer than when it starts

Yes. It's something Samsung has had for ages now. I mean Google took the time to create a scheduled system for blue light reduction, yet couldn't bother to do the same with Ambient Display. It's either on 24-7 or off.
The best solution I've found is to put a piece of paper or such over the top sensor at night so the phone will think the device is in a pocket and turn off the screen.

The best ideas are the easiest sometimes. I stay away from Samsung. I can't stand trying to figure out where they put stuff at. Why change menu structure even. I've tried several times because of the awesome hardware but never make it past about 2 months.

Cheers for the tip! :good::good: We've done my part now let's wait
I just got my pixel 2 XL and can't believe google has not enabled this already, it's a very basic item and a must have for many.
Pretty pathetic, hopefully once roms start dropping this will fix many shortcomings on the device.
As mentioned in an different thread, using Accubattery will display the battery level on the AOD. In my brief testing, Google reported the app as not consuming any measurable amount of power overnight, so no appreciable battery draw. Also, there is a root app from an XDA RC that displays the music you are currently playing/streaming on to the AOD. This is different from the existing "now playing" feature already built in, and at the end of the article HERE it says that almost any "text" can be displayed on the AOD. It's not the built in Google controls for the AOD we are expecting, but there is hope for customization for those with root, and in the coming ROMs.
Well, got this notice, just don't know what "Changed" (shrug)

You can either use the new Screen Brightness or turn if off completely.
Have you tried training it for a few days by adjusting the brightness to your needs?
For me, it works perfectly after the training phase.
There is no way a normal user can do it, on a locked device. I am sure there are ways with root there are ways to fix this. This was my biggest issue for a week when I got Android 9, and now 10 (since in 10 whatever was learned in pie, at least for me, was lost). After a week of teaching it how I want things to do, it just does it at it should.

The point is ML doesnt obey my commands. Thats why i want to disable it.
It learns ok. but when it finishes his learning phase i cant control the Brightness manually.
For example:
ML increases Brightness to %100
but thats too much for me for that moment
so i am trying change it to %50 and then
ML immediatly increases Brightness to %100
I cant control the Brightness after the Learning phase. Its just so dumb.
I just want back my old but gold Light Sensor.

Indeed, you are right, the old fashion system pre-9 was much better, and much more reliable. You set a point on the slider and the auto-brightness only modified slightly in that area. Until the auto-brightness post-9 learns it's a chore, and after that... teaching it new things, it's again a chore.
The whole process is related to the Device Health Services subsystem where you can reset the whole learning to factory default. Maybe from there, you can have some success, but from what I've googled, there is no way to do that on stock locked. Maybe there are xposed, or magisk modules that could take care of that.

Wow.. I have never seen that. Been using 9 since it came out, with the latest sec. patch every time. I've adjusted the brightness many times, but I've never seen this happen.
Is it the same if you drag it instead of tapping a new location for the knob?
Also, I have the complete Digital Wellbeing bs disabled for a long time now, maybe that's why I've never seen this? Might have to do something with it.
