[Q] Auto brightness not working - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi!
I have the S6 edge since yesterday and I noticed that auto brightness does not work.
Testing the senosr via a sensor read out tool, it actually detects brightnes levels well (as far as I can tell).
However, if I turn on my phone, it is first super dim at first. When I expose it to a flash light, the screen turns brighter and eventually maxes out. But it does not turn back to normal brightness levels once I remove the light source. Sure I can adjust auto brightness with the slider. But it is then much brighter (with same light conditions in the room) as when I truned on the phone...
Only if I turn off auto brightness, the screen reverts to the setting I have chosen...
If I turn auto brightness on again, it is as bright as with flash light exposure...
What is going on here?
Does anyone have an idea how to fix this?

I have the same problem. Already talked with Samsung and ATT. They want me to change the phone.
Ps. It seems the problem only persists in S6 edge not in S6. But I also found that other android that run lolipop 5.01+ have the same issue too. And right now, I use the app name velis auto brightness to fix this.
I will try to change the phone by this week and update you.
Hope this help.

I have started using an app called Lux. And it has no problem adjusting the brightness. The sensor clearly works fine as it can always displays the brightness detected by the sensor. So it has to be a software problem.
I could imagine that a hard reset could fix the issue. But right now, I do not want to go to the hassle to restore everything
Let me know how the new phone works. :highfive:

The hard reset did not work, I already did it.
I will update you again once I change or test the other phones.

I went to the store, and both S6 and S6 edge in the store all have the same problem, so the exchange it may not solve the problem.
I think this problem may be a software problem or an intention from Samsung/Google.
I will try to use it in couple days. If I cannot bear this, I might return the product.
Hope they will have OTA update soon.

Got this too.
It's really anoying.
I really hope there will come an app like on older Sammy's that we can set and adjust our own brightness levels.
But I'm not expecting a fix from Samsung tho. They have proven again and again they are unable to fix their crappy software. Especialy if it's a minor bug like this.
So anyone wanna buy a rooted hardly used S6 Edge plus?

Auto brightness

Does anyone have a solution to auto brightness issue?
Even in the darkest room, the lowest light level is "medium" and not low! Its excellent setting when using phone outdoors but in dark room or at night its just too bright. Is my phone broken or is it general windows phone setting?
Sent from my TITAN X310e using Board Express
on my titan, the auto brightness behaviour is erratic and sometimes goes too low.
the camera is one of the issue triggers. after every return from a photo session, the screen goes to a lower brightness.
also, sometimes it happens when unlocking the phone but i don't know what triggers it. then suddenly the screen would return to its normal brightness after a few seconds, although not always.
i suppose it's a driver issue...

so you get the autobrightness to go as low as 'low' set manually? - I tried it but even after camera the lowest brightness I am getting is same as 'medium' when set manually!

no, not that low only lower.
but you are right, even in complete darkness the screen won't go to its lowest setting...
Yes same issue here.
Automatic can go a little bit lower than medium, but not much. Too bright in dim environement.
For general use, i would like to have a preset between low and medium
Since these days many people like ultra bright screens (and ultra loud sound) i am not sure HTC will try to fix this "issue".
I just hope Microsoft can add a brightness slider in the future. (Or bility to set the min auto and max auto levels)
Btw, do you know why camera mode go into max brightness ? This is a little harsh indoor.

Yes that behaviour is very strange too! I think it's present only in the Titan. Some other windows phone manage the camera brightness a little better. But then I think increased brightness while using camera sort of makes it little pleasant when using it outdoors. But indoors as you mentioned, it's a bit too harsh brightness!
I think it's the light sensor that doesn't work properly. Some places/forums mentioned about issues with various HTC driverseven after those 2 softwares updates we received in Nov-early Dec.
In daylight,the auto brightness works wonderfully for me,I never change it.
But in a fairly dark room,it's too bright and most of the time,I set it to low
I usually set it to medium... and set to low by myself by night.
I have sent a message to HTC (via theirs contact/ticket system) about the "can be improved" auto brightness, and "camera set brightness to max" issues.
Better than nothing.
Since this is a easily reproductible problem, maybe they can take a look if they receive several messages about this.
I wonder if the screen going to max brightness with camera may have something to do with the "HTC Camera modes" addon ? (who knows..)
But i don't see how to remove it. I even can't find it on the marketplace (under HTC section).
I have same issue, I get blinded when I check the time on my phone at night
It was there even before camera modes update was applied by HTC. So unlikely

Obviously, the brightness go to max too when using skype with video.
Hope they will notice and fix it.
Trying to talk to HTC customer service is especially unhelpful here in france.
They have absolutely no knowledge of theirs WP7 products
(whatever the problem encountered)
Now that we have unlocked roms, any way to tweak the auto brightness ?

I've tried all 4 ROMs and they have the same behaviour as stock ROM at the moment. But it might be useful looking into the registry threshold values. I know there is some sort of home brew app that lets us set the volume increase in 10s, 20s, 30s or 50s. So a regedit might be somewhere, will dig around myself since you've reminded me again

[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

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] Full Brightness waves

I am using z2 about 10 monts. Today i feel when i put mobile full brightness i observed some wave running from top to bottom. Specially observed when open NDR utility and es file explorer. Before appearing the both applications interface waves appear for instance. I am worried is it ok or some problem. And also today observed brightness bright more autometically, althoug i am on full brightness. Any help suggestion Thanks in advance
I've noticed the brightness change on its own too sometimes. I always use full brightness (adapt to lighting conditions disabled) and randomly, I'll notice my screen get brighter or darker sometimes. It's completely random, not sure what causes it.

Omg I thought I was the only one, My brightness is set at 100% when I quickly unlock the phone I notice a quick dimming on the screen even though it's at full brightness...

Yup I have the exact same thing. Not sure if others have it as well, but as far as I'm concerned, it's normal (I hope)

Android 6.0 Adaptive Brightness Spiking and Dropping

I'm using a stock BLU R1 HD running Android 6.0 and within the last month, give or take, my phones brightness has randomly been spiking or plummeting before evening out into something legible. I also use Twilight(With pro unlock) and I have for years. I have disabled Backlight Control in the app. I have tried to go into my settings and disable Adaptive Brightness, but it will not stay disabled and turns itself back on as soon as I leave Settings. I've recently installed Lux but the problem persists. I've been googling it and all the responses I find are from 2015, give or take, and most apps regarding brightness have also not updated since around that time.
The frustrating part is that most of the time when it changes I'm not even moving and the light around me is not changing. The problem actually occurs more in normal, indoor lighting than it does in darkness or bright sunlight, and I've been careful not to cover the front camera, where I think the light sensor is, just in case I was the problem.
Does anyone know what I can do? How I can either fix Adaptive Brightness to stop randomly changing my brightness for sometimes 10 to 15 seconds before going back to where it should be, or how to disable Adaptive Brightness so it will stop turning itself back on?
I'd prefer not to root my phone, so please don't suggest it unless there really is no other option. I've ruined several phones that way in various ways and have concluded that rooting is just not for me.

Brightness automatically changing even with auto brightness turned off

Hello, I'm using a Samsung Galaxy S7 Edge and I've had this annoying problem ever since I got this phone in 2017. The screen brightness keeps changing automatically even though I turned off auto brightness.
https://streamable.com/c5q9w
Here is a video example. As you can see, the brightness changes by itself when covering the light sensor, even though auto brightness is set to off. It might be hard to see the difference in the video but it's quite noticeable in real life.
Is there a way to fix this?
