Poll: Auto-Brightness, Full, or other?

Hey guys - just wanted to create a little poll to see who leaves there screen on auto-brightness, full, or manually controlled but somewhere in the middle.

I use auto, but I use tasker and screen filter to turn the brightness automatically at night.

Auto-Brightness unless I read in a dark room where I manually set it to the minimum (auto usually puts it there anyways). The other exception is when battery is low, I put it at 0% or whatever minimum allows me to see something.

I'll submit a vote when I can indicate minimal brightness. More than bright enough for me unless I'm outdoors.

i usually leave it on min. brightness and turn it up when needed (e.g. outdoors)

i like SGS to be set on auto, it works better than on the SNS
on the SNS i need to set it to manual

I use auto mostly and manual ( 0% brigness ) when watching movies in my room )

I'm at minimum most of the time (voted 'at the middle' as it is the closest).
Please fix the poll!

Auto-brightness most of the time...

i cannot vote as i leave mine on minimum brightness to conserve battery

Almost always at minimum, and often auto when outside.
Minimum being too bright I also sometimes use Screen Filter.
There should be an option to use auto, but choose relative brightness (an offset). Using Screen Filter almost does that, but it is too unstable.
Even beter would be to be able to tweak a response curve : screen brightness in function of ambient light (I want it dimmer inside, but still full brightness outside with sunshine)
I think Samsung does not allow screen to be too dim also because it then shows too much imperfections in amoled...(ex. plain white is not uniform at all)
Using Screen Filter to dim a lot brings bad looking screen. But I guess a great part of it is due to number of colors too low, so you loose too much by filtering. Maybe Gingerbread will improve in this matter (doesn't it manage more color shades?)

I use auto most of the time, except for image viewing and video.
I use JustPictures as my image viewer and set it to automatically turn brightness to full when looking at an image.
For videos I use mVideoPlayer which has a manual brightness override which I usually leave at about 50%.
I also use the Speedmod kernel which allows the brightness to go even lower than normal if you use manual brightness. I use this low setting when using my phone in the dark.

automatic brightness behaviour

Hi!
The automatic brightness on my Xperia Z behaves weird (altough I think it is a bug)
This is what happens:
I have the phone set to "adapt to light conditions" (automatic brightness)
Now when I slide the brightness slider, the brightness changes. But, depending on the setting of the slider, it will not go to full brightness or darkest on its own. When I turn off "adapt to light conditions", it becomes brighter or darker, depending on slider position. But it will never go to 100% on it's own, not even directly under a lamp. It also becomes a little brighter when I turn off automatic brightness and have the slider set to 100%.
Expected behaviour:
I turn on automatic brightness, and put the slider in a, let's say, 60% position. The phone goes to 2% brightness in a pitch dark room (when I read in bed) and switches to 100% when I'm outside in the bright sun. When it does not sense extreme conditions (e.g. sensor reading <20% ambient brightness or >80% respectively; then gradiently going to darkest or brightest gradiently, of course), it aims for the +-60% brightness I specified with the slider.
Conclusion: The slider is an overall threshold for screen brightness and it does not adjust in a 2-100% brightness range, but around maybe +-30% or so around the position the slider is set at. This sucks!
This seems to clearly be a bug, and imho this contributed to the somewhat "not so impressed with the screen" reviews I read before I bought it. Because the screen is really very good if it is set to the correct brightness.
Thanks for the answers!
PS: When I enter the service menu with *#*#7378423#*#* and check the ambient light sensor, it gives me values between 0 and 1000 - so it does definitely work correctly. Build number is 10.1.A.1.350 - I know there is a newer one, but my phone is carrier branded (3 Austria, for that matter) and hasn't been updated yet, unfortunately. Can someone confirm that is is fixed in .434?

I dont think this is a bug. It's been like that on the t, tx, v since they were launched.

Really? This is almost a deal breaker for me :/ that is a really stupid behaviour, what do I need automatic brightness for if I have to change it myself anyway? I really don't want to care about this miniscule thing on a 600€ device - I expect it to adapt to all conditions.
I didn't want to root it or put a custom rom on it - Sony did a good job with the software as it is, except the automatic brightness.

Sony phone has the best auto brightness
You can find on any phone.
You can say Samsung's auto brightness sucks but not Sony
In auto mode you have the choice to set the minimum brightness level you want and the level will go up depends on the lighting situation and sensor reading.
Yes it has some threshold limitations but it's very sufficient.

Sorry, but "best auto brightness" is not what would've come to my mind thinking about the xz and I would never buy a Samsung plastic brick
I had a Nokia N9 previously (that I miss dearly, but the internal 3G antenna was broken so I had to replace it... still by far the best phone I ever owned) and it had exactly the auto brightness behaviour I expected - when I read in the dark, it when down to the lowest possible setting. And when I was in bright sunlight, it went to full brightness wihtout a delay or hassle. I could read it perfectly under any condition and never thought about the settings. The slider only indicated a preferred standard brightness - always had it at 60% and it was perfect.
I really don't understand why other manufacturers wouldn't do it exactly the same way? As I said before, why even have an auto brightness setting if I have to go to settings to adjust it anyway?!?! If I put the slider on 60% and auto brightness on, it burns my eyes in the dark and I can't read it in bright sunlight - I even have to adjust it when the sun shines through my windows at work?!?! WTF Sony?

We are talking android here
I don't know if you had the chance to use gingerbread,froyo....
Maybe android has some limitations.

iirc it didn't annoy me (and boy am I picky about details like that! ) on the HTC Magic (up to the last CM that supported it) and the Nexus S I had before the N9... anyway, seems I have to get a decent brightness toggle widget :/ (maybe you can point one out?)
but thanks for your replies!

just for the record and anyone who may find this thread in the future:
I just installed "Auto Brightness" and it seems to work well and has tons of settings. Would have preferred a more native solution... I hope this doesn't drain the battery.

Brightness Management: What's the best way?

I don't know if anyone else feels this way, but I tend to think that the auto brightness setting on stock lollipop is WAY too bright, and, while of course it shows off the screen, it wastes battery life.
I can turn on power saving mode to try and dim the screen to some extent. I've also given Lux a try, but it didn't really seem to do much...
Does anyone have an idea for auto brightness which works similarly to how CM12.1 does it on this phone? Where you can set how bright you want it to be, but it still compensates for ambient light?
Thanks!

I like screen filter. It's very simple and you can pick which percentage you want. I've gotten it lower than stock. I'd recommend giving it a try. Couldn't hurt.
Not sure about the ambient light bit, last time I used it was on my note 2. It may be available.

There's a setting for ambient light too.

Brightness, no more Auto

I haven't used Lollipop at all yet, just picked up the N6 yesterday. Autobrightness is gone, now they want you to slide around the bar to however you want it with adaptive brightness? now how does this work? lets say I set it to full brightness and enable adaptive, itll use anywhere from 0-100%? is the bar just to cap it somewhere so it doesn't exceed? if so what do you have yours set to? Whats a good way to do this all and avoid image burn, ha. which I Heard is kinda a big deal

That's exactly how adaptive brightness works. I have my slider set around 25-30%. I change it if I need more outdoors.

This is how I understand it and how I believe it works.
With adaptive brightness OFF, you have your brightness slider in the pulldown that goes from ~5% to 100%. This slider set value will remain until you manually change it. Easy enough.
With adaptive brightness ON, you have that same slider in the pulldown that goes from 0% to 100%. Your brightness will change automagically dependent upon ambient light. Look at it as "minimum automated brightness level"
Some tips. Your screen can get darker with adaptive ON and slider all the way down than with adaptive OFF and slider all the way down. Unless in very bright ambient light, your screen can get brighter with adaptive OFF and slider all the way up. Hence, in full sunlight, the peak brightness of the screen is the same with adaptive either ON or OFF and slider all the way up.
I admit its confusing and it frustrated me at first, but I think its excellent and works much better than auto brightness on any other phone or older android OS I've ever used.
As far as burn in (or the more often occurring image retention), well its an amoled, it's susceptible. Just be smart about it and don't display the same static image/s for hours on end.

I used to think that but after testing, it seems more complicated than that.. It also looks like to may apply a "range" using the slider, but its more complicated than that too.
The closest thing I can think of is it increases the sensitivity or effectiveness of the adaptive brightness.
Have a look at our tests here, maybe you can do some testing and develop our initial findings.

I'd love to set it to an exact percentage cuz I'm ocd that's why I hate the slider. How do I really know it's at 25%

Yeah but once you know 25% is 63.75 on the brightness scale and brightness can only register full numbers, you're day is blown anyway.

I think you nailed it better than I did in my explanation with your statement "increases the sensitivity or effectiveness of the adaptive brightness".
My explanation was as simple as I could write it. I especially like the word "range". Thanks for the link I'll check it out :thumbup:

So is it true if its set half way if the sun hits it that it can use 100%. What do you guys have it set to? I liked the auto brightness ?

Yes if the sun, or even very bright ambient light hits the sensor, the display will go to 100% full brightness with adaptive ON. At least it does with mine (to my aging eyes). I leave mine at about 50% adaptive ON. I like it too

I use manual.brightness.

For everyone testing display settings have a look at 'Pixel battery saver' in the play store.
The app switches patterns of pixels off and saves energy.
Note.
Because this kind of apps are switching pixels off, it is possible that ticking buttons will not work.
But there is an option to turn it off, and several levels of settings.

Screen brightness setting not sticking?

Anyone else's lower end brightness setting not sticking? I'll set it like 1/4 of the way which is pretty low and I understand the brightness goes up by itself when in a bright area but then it won't go back down to how I had it set. It's on auto mode to but it still should go back down to how I had it set when I'm out of the bright area.

lol. I have never had a working brightness on any samsung phone i can remember.
my note 3 was the best at keeping what i set.
The note edge so so, then s7 edge same thing, there would all change on there own.
Now the note 7 i have it at full and its been staying there so far but i did lower it to 85ish to get better battery yesterday and so far its holding.
I have auto turn off.

It will go back down.. try this
Once you return from the brighter area (outside, under a light, whatever caused it to increase brightness) lay the phone down for like 3 seconds. It reverts to the previous brightness.
You can also hold the phone flat on it's back in your hand to simulate setting it down, and it reverts it

I don't like the brightness settings on the note 7 either, as far as I know from previous phones you could turn auto on and the slider would adjust the bias, now it seems that you can either set it manually or auto but auto has complete control and you can't adjust the bias, that annoys me, I want it to be adaptive, but I want it a bit dimmer that what auto sets it to, I hope here is a solution to this.
