Auto Brightness problems?

Auto brightness seems to behave very unpredictably--when I wake my phone and unlock/use it, it will remain at dimmest setting (too dim), and will seemingly randomly move to a more appropriate brightness (not with intense activity, it's really random), and will again randomly revert to dim setting (not with stoppage of activity).
Is auto brightness messed up with android or the note, and how can I fix it? Just set a manual brightness level?
Running cassie x lite rom and latest franco kernel btw.

No advice about this anyone?

Automatic brightness issue
Hello Friends, I have a similar problem as the OP, octavian90.
For my Galaxy Note, following the sequence below,
Applications > Settings > Display > Brightness
By default the slider for Automatic brightness is towards the middle/centre.
I have unchecked Automatic brightness and calibrated the slider to the extreme left.
I have come across the following strange observations -
1] When I unplug my device after charging, the slider resets to the default level.
2] After I recalibrate it to the extreme left once again and make a phone (voice) call, the slider resets to the default level over again.
Is this normal behaviour or does my device actually have a problem? I am very confused and worried. The device is not even a month old.
Eagerly awaiting your expertise. Thank you octavian90 for initiating this topic.

Friends, awaiting your much needed replies to my queries above.

Have you disabled the screen saver or what its called that adjust the brightness automaticly.? Works like a auto brightness but it can adjust some things brighter and some dimmer eaven on same light....

I just checked my settings and the have the slider all the way to the right because last time I manually adjusted brightness for reading in full daylight. It is currently on automatic brightness (I prefer that setting and don't find it changes too often or too laggy)
I just then manually adjusted slider to about 20% from left while on USB charge then turned automatic back on again. I then removed charger and it still shows automatic and slider about 20% from left.
Could be a ROM/Kernel issue? I am using Rocket ROM with Franco Kernel.

I don't think the position of the slider matters when backlight is set to auto. Or does it?

No it doesn't matter when on autobrightness. But it should remember the last manual setting chosen so not sure what is causing that glitch.

Hm never really paid attention to the behaviour of the slider. I will take a look and report back how mine works.

What I found out: On my device the position of the slider before activating auto mode is completely irrelevant because as soon as I activate the auto mode the slider is reset to its middle position.

Interesting - just turned autobrightness of and you are right - slider went to the middle. Must be by design then. Problem solved

Sorry SoonHD2, I did not understand what you meant. I am confused with the screensaver part you stated.
A humble request for an explanation, if required. Thank you.

This happens with my Galaxy Note as well. Thus, it seems like it is meant to be this way.
I will keep an eye on this and report if and when the Auto brightness slider acts differently.

MeMo Pad ME572c fluctuating brightness

Just picked up an ME572c and I'm very impressed for the price. However I have noticed the screen brightness levels keep fluctuating as if the light sensor is constantly detecting different light levels.
Has anyone else experienced this?

Hi,
i notice this too, but that can be related to the power saving mode. Plz turn it off and check the settings in detail. Maybe that helps.
Further inside the developer options there is another option to configure the auto brightness.
You can change the behaviour from dynamic to immediately or slow mode and active an onscreen lux, gain and brightness value display.
Btw i am not satisfied with the auto control, as for my taste the brightness is still too low in a less lighted room. Sensor is reporting 0 lux already with a brightness of 14 which would be ok for a really dark room & night but not at daytime.
What is your experience?

I tried playing with power saving mode and the auto brightness controls in developer options. While I could reduce the fluctuations, I could eliminate them completely. Unfortunately I found it too distracting and returned the device earlier today. It's a shame as everything else was quite impressive for the money.

I also found the fluctuations annoying, my solution was to turn the auto-brightness off. Honestly I dislike auto-brightness on any device, it was also one of the first things I turned off on my laptop.

I am using Lux app now and raised minimum brightness at 0 lux. Thats ok for me now.

Just bumping this to confirm this works and so that others can see. I used Developer options as well (before I found this post) and noticed the instant setting works best.

One more setting to also double check... Make sure that in developer options under auto brightness that you disable allow change gain...
Even with everything disabled it appears as if something still is changing the display. I particularly see it with something like a reddit browser when I'm viewing pictures. You click the pic, it loads and displays and then 1-2 seconds later the display adjusts based upon what is being displayed. Depending upon the picture it can be pretty annoying. I may have to root and start poking around to find out what is causing this.

with the lollipop update this issue is fixed for me.

Is lollipop really solve the problem?

Hello!
Im on lollipop, but the problem you had, still occur at me.
Did you noticed this problem, since you on lollipop?
I have the same problem. When i read, or browsing, the brightness changes in 2-3 steps.

[PIE] Adaptive brightness issue?

Good evening,
just wondering if anyone else has issues with adaptive brightness after the latest PIE update? Since the update it changes the screen brightness during low light conditions from semi-low to low without any reason. And in normal light conditions it sometimes gets way too bright. And it doesn't modify the screen brightness in small steps but in one "big" step.
Btw: I did not wipe my phone before upgrading, maybe that's part of the issue.

yeah same issue here. phone seems to wake up in very low brightness mode randomly?

same here.

You will have to go back to the display brightness and adjust to the level you like, then subsequent light condition will then be adapted to your new value.
Hope this helps.

Same here. And I did full reset, after Pie upgrade

It needs some time to finish learning, Adjustable brightness Android 9 feature is now AI controlled. Google it.

Auto brightness issue

Anyone else having issues with auto brightness after the pie update? My phone sometimes does not change the brightness automatically when I move from a bright to dark environment until I turn the feature off and on again.

go to a dark place slide the brightness to desired level. no go under a bright ligh then shut it off and see.

Just tried this. Sometimes it works and sometimes it doesn't. When it doesn't I still have to turn it off and on again for it to work again.

it's the new adaptive brightness..... you set the desired light in each situation over the next few days using the slider (adaptive ON)... it will adapt to your preferences in different situations.....

Thanks I'll give it a try.

Doesent work with my note 9 Pie...
I Flashed ota from 8.1 and later i flashed back to 8.1.
Later i flashed again 9.0 but this time not via ota. I flashed it clean via odin.
Same issues with adaptive brightness :
1. It does NOT learn my pattern. This means : I turn it darker. And later in the same spot it turns it back to the middle... Over days and days the same.
2. If you turn on the camera-app, it turns the brightness high. That is okay, i like that. But if you turn the app off, and if you are too fast for the system, it stays enlighten untill u lock ur device !
Oreo :
1. It learns my pattern from day one (!). I turn it darker. Later on the same spot : It stays dark ! Perfect
2. Turn on the camera app and it got brighter. Nice, like Pie, right ? Yes, but turning the camera-app off and swiping it instand away from recent apps, it turns imediatly back to the normal brightness, it learned from you !
I hate it ! Pie does not work fine with my brightness preferences !
Other user in other forums have the same issues with pie...
And there is no way around. I tryed it all. Every option and every possibility. Iam not a beginner in android.
I gave the adaptive brightness a cance of 10 Days, but every day it learned nothing. And the Camera problem...Turn the app on and open recent apps and swipe the camera away and then go back to home. If u do it too fast (I do it every time on every phone with MY speed) it stays bright like u throw it in the sun

Same here adaptive brightness has gone bonkers for me after pie upgrade. Just like you it works when it wants to. Really frustrating.

So please guys, tell samsung that problem in the members app.
The users in our german forum did that, and i did that too.

I fixed the problem by doing a factory reset.
