[Q} Is there a way to raise brightness when set to auto? - Nexus 7 Q&A, Help & Troubleshooting

Since my OG Droid I've never used auto-brightness because the sensor placement made it pretty unreliable. With the Nexus 7 I don't seem to have that problem, but the it always seems to be one step lower than I wish it was. Is there any way to change it and keep brightness on auto?

Not without rooting and using something like what is in CyanogenMod. Instead, turn off autobrightness and get one of the myriad brightness control apps that let you set the brightness how you want it to be.

Crappy Automatic Brightness Sensor?

Is it just me or does everyone's Epic's have terrible brightness sensor hardware/software? My sensor seems to have about 2-3 settings of brightness, and goes from completely dim to super bright in random situations and nothing in between.
Cyanogen just posted on his twitter that in the past he changed the sensor's abilities through coding modifications. Could we do something of the sort for the Epic's sensor?
Agreed. The sensor is horrible. Also, the transition between brightness settings when set to automatic is near instant instead of slowly transitioning, which makes it more obvious that its changing brightness.
I would agree that it is terrible. Mine also send to sometimes turn auto brightness back on if I've turned it off.
It would be great if someone found a way to mod the code for it!

I thought the screen was just too bright at its lowest setting. Fortunately someone came up with a fix for it that can be found in the developer section. As far as the automatic sensor I would suggest turning off "Power Saving Mode" in the Settings>Sound & Display as well. I've read somewhere that this causes the brightness level to vary on its own.

Hehe, that was me. Stay tuned for more. I have coded up and will post, tonight, a new version that will let you modify the brightness curve (from the command line, for now)
As for automatic mode, I have figured out how to modify some aspects of it at the kernel level, such as the ambient light thresholds at which it switches to a different brightness level. By modifying the brightness curve, we can achieve at least some more control. But to make it really good may be significantly harder.
Personally, since manual brightness is always available by swiping horizontally on the status bar, I have little desire to use auto mode anyway.

The sensor is actually pretty sensitive. It's just that Samsung chose to have a really small range of brightness steps for automatic brightness.

More like they installed an awesome dimmer switch and lights, but the fixture only does three modes; high, medium, and still pretty damn bright.

[Q] Do you use auto brightness or set value?

Just curious to see what everyone does on their tablet. I stick to using auto brightness but turn it up every once in awhile when browsing the web. The screen is just very nice to look at IMO. So what do you guys do? If you don't use auto brightness, specify your brightness sweet spot.
I have auto brightness off and set to the lowest possible setting and only occasionally adjust the brightness higher.
I also use the lowest possible setting. When I need to change the brightness, I use an app "Display brightness".

Auto brightness in 4.2 is one big bug
I would love to go back to using auto-brightness but it's a buggy piece of **** on 4.2+, it's been over a month now and they still haven't fixed the ****ing screen flicker issue, completely disgraceful.
http://code.google.com/p/android/issues/detail?id=39841
I use set values from Extended Controls widget. I have it to like 7%/25%/36%/64%/100% and switch manualy according to what I need. Auto brightness never worked good for me on ANY android device

Thank you for turning me onto Display Brightness! Now I don't have to depend on auto-brightness and how it drains the battery! I'll be upgrading to the Pro version to support the developer!
BTW... I'm so glad it doesn't black out the screen completely, otherwise I would probably have a Razr with a completely black display (I was testing it on my Razr before I installed it on the N7).

Auto brightness not working correctly

When I'm in a light room the screen goes brighter but if I walk into a darker room, the screen doesn't dim unless I lock and then unlock the screen.
Anyone else having similar issues?
Yep got the same here. Thought I had a faulty ambient light sensor but obviously not.

Just tried it by covering the light sensor to make sure, no problem here (G935F). My only concern related to brightness is that the s7 just has auto brightness, but no adaptive brightness.
Uncheck the auto box and recheck. Then don't touch the slider. It's usually because in marshmallow the slider moves with the auto bright and most people touch it which makes it hold position.

There seems to be a bug somewhere still. I just tried to move the slider while auto brightness is ticked and to cover the light sensor afterwards again and it still worked and to my surprise it even took into account that I lowered the brightness and took also a lower brightness at the covered state and took my initial setting after uncovering, pretty nice, so there is indeed still adaptive brightness. After ticking und unticking auto it went back taking the default steps for brightness as before.
Having the same issue here
Definately not touched the slider.
Also, I have tested the light sensor and it appears to work fine so definately a software issue. Though I imagine we will see some software updates to fix bugs shortly after the official release date.
So you can adjust the slider with the box checked and get various levels of auto? Does it learn?

Yes.
I can't tell for sure, when I change further steps the previous seems to stick, at least to some extend so there is a logic behind it, but I can't tell for sure if it really is based on each step and sets it accordingly or if it's just changes the range it operates in. Anyways I'm a happy camper.
Also, I could reproduce the device not changing the brightness, when I put it to full at darkness it won't move anymore in auto. But as soon as I lower it again it will also change accordingly again, maybe at those with the stuck brightness the min brightness is only raised, but not lowered anymore, but just an assumption and doesn't help anyone atm unfortunately.
Use lux in play store

This is the first Galaxy phone I had, that Auto brightness actually works the way I like it.
It seems to be working fine now. It just takes a few seconds for the screen to dim (maybe I was being impatient).
After testing it further it's actually really good auto brightness.
It works, just takes some time to adjust to the lighting. Maybe the default settings are set to a certain time. Maybe with root we can adjust this..

It seems to only do it quickly when the device is lay down (as 954wrecker said). Maybe Samsung did that so it doesn't annoy you when using your phone.
this is definitely a bug imo... the auto brightness doesn't change for me either...

I also have an auto briteness issue, when I disable AutoBrite and set it manually about half my apps override the setting and enable AutoBriteness in the app's screen usually dimming the screen? SpadesFree one example and I do not see an override in the app.
Confimed that I'm having same issue, auto brightness not adjusting and slider not movingoing. Have to move it manually
Same issue. It needs to be fixed manually by editing services.jar (root needed)
Nothing else will work. None of google play apps will help with that issue. Does not matter what you do, it will always dimming if you don't fix it in framework.jar

Auto-brightness still too low on 4.5.11

Hello guys, I installed 4.5.11, but auto-brightness is very agressive, many times i find it on the lowest setting. Any way to fix this? I just want it a bit higher.
Seems like Oneplus is having everything that saves battery on, from brightness to Doze. As some notifications didn't show untill i opened the app. Usually whatsapp. Personally, instead of 7h of screen on time, i prefer having "just" 6 and everything working good. Just got this phone, 6-7 hours of SOT on a 3300mah battery is insane!
This is very stupid. I have the same problem. I dont know why OnePlus don't make AutoBrightness ajustable like Samsung in Touchwiz for ex...
same with me, when autobrightness in darker room, display is always set to lowest brightness ever. really annoying.
On my side, I really love the way auto brightness behave on my OP5. Too much light is not good for the eyes.
Exactly, the user should be able to set a default level, then auto brightness goes from there.
For those who have sensitive eyes, you can always use night mode. It just block the blue light that is mostly responsible to keep is awake.
When the auto brightness is too low did you go into Settings / Display and move the Adaptive Brightness slider to your desired brightness? I am now in a very dark room and the slider isn't all the way down to the minimum. I can see my screen fine.

Yeah or i do it from the status bar. Still after a while it returns to a lower level. While i already want it on a low level, it's too agressive. I whish i could raise it by 10-20%.
Yeah, that slider doesn't adjust the adaptive brightness level like it would on a Nexus or Pixel device. It remains as a standard brightness level instead

Well, we could install xposed to fix the brightness. But then i don't know i want to install all of that just for brightness.

Automatic Brightness too low

Automatic brightness enabled on my new OP6T. It constantly goes too dim, where I have to slide it up some to see the screen better.
Unlocking the phone an hour later, in same low light setting, the screen has auto dimmed itself too low again.
Anyone else feel it goes too dim on its own? Or have a solution for me?
A maximum dimness setting would be nice. Not sure if that exists though.
I'm with you 100% it keeps defaulting back to a brightness that's way to low for the environment have to constantly raise it manually. A minimum brightness setting between certain hours would be great.
I wonder if something like that can be done in tasker, keep automatic brightness on, but set the minimum to 25% or so during certain hours.

This exactly!
It's generally really low. The worst is in the dark, it's almost unseeable, unless you manually adjust it.
Phone has great battery life I just crank it 100% outdoors and 75% indoors.
I agree with what others have stated but that's why the battery life is good...I'll drain it to appease my eyeballs.
Does lux work?
+1
hopefully can be fixed with an update...
My phone was like this for the first day or two. After that it's been just fine.
I don't know if it fixed itself, or I've just gotten used to it. I'm thinking the first because it was really dark.
I have observed this on different phones. So I suppose this is an android issue. The brightness goes too low than its supposed to or it will keep adjusting. I've tried lux auto brightness on other phones, it works perfectly. But due to lack of updates I've stopped using it lately. Custom ROMs seem to handles auto brightness very well. I've tried Cyanogen and Resurrection remix on moto x play and Honor 8 pro, auto brightness was never a bother on them. Which was not the case with the OS they came installed with.

I've compared this yo my pixel 3xl and in low light situations its noticeably darker. After a few days I'm already used to it.
The smart adaptive brightness adjusts to your usage over time, once you manually raise it afew times in various situations it will adapt to this. Mine was dim to begin with but after 2 days it's fine.

LUX works after enable it in usage access. Settings>apps&notification>special apps access>usage access.
