Screen brightness goes down automaticaly.

Hi,
Everytime my battery goes down 15%, my screen brightness goes to almost 0.
I cant see any setting to change this.
I dont have any app to do that.
Currently rba023 rooted.
Thank you

If there's a way to change it I would like to know as well. It's very hard to see for that last 15%.
Wish I could help.

The last 15% would last no time if it was at normal brightness. It's designed for, you know, if you need to use it in an emergency ;-)

To get your brightness back go to the sound and display setting and click brightness. It returns it to full brightness. When your battery drops to 10% and 5% it will do the same.
As far as I'm aware there isn't a proper solution to this.

My issue with the brightness is the "auto brightness" function seems backwards to me.
E.g. if I am in direct sunlight, auto brightness turns the brightness of the screen way down, which means I can hardly see it. If anything the brightness should be turned UP.
If I am in a dark room, auto brightness turns the brightness up, when really, turning it down would be better as it doesn't need to be as bright in a dark room. So it should be turned DOWN automatically.
It's arse-over-tit, as we say.

Yes,
But now with root, i'm sure anyone with the right knowledge can modify this 'stock setting' ! ...
Anyone to try it?
Cheers!

This doesn't really fix the query but for fast access to adjust the brightness I use an app called QuickSettings which I have on my front screen to give quick access to some basic settings. On the brightness adjuster you have to have the phone settings not on automatically adjust.

Screen Brightness Keeps Changing

I took off the automation for the screen brightness and I manually set it. However, after about a day and a half it changes by itself. I can not figure out what is changing it. I use Dolphin browser...but I don't think that is changing it. Does anyone why the screen brightness is not static?

for web browsing the brightness setting can be different then the phone itself .. idk if thats what u mean but just a little fyi ... since the update however if its set to auto ive found the web browsers brightness is not adjustable

For me it was doing the same thing till I noticed that the drop down curtain at the top of the screen is a manual brightness adjuster as well. If you happen to drop it down just enough to see the date and move your fringer to the right it brightens, if you move it to the left it dims. I found myself pulling it down and accidentally changing it alot until I figured out why. Since then it never changes now that I know to pull the curtain straight down and don't move left or right with it.

Another setting that I noticed would randomly adjust the backlight brightness is Settings -> Sound & Display -> Power Saving Mode. I've disabled this and my backlight no longer changes an I have noticed no difference in power consumption (with it checked or not, the display consumes a lot of power ;-)

This was sooooo frustrating for me until I found that setting and unchecked it. When I turn off auto-brightness, I don't want the brightness changing unless I change it lol.

That's gotta be it! Is there anyway to disable that?

setting it to auto brightness will

This sounds kind of funny when I had autobrightness and the powersaver automation on the battery would drain faster. When I turned it off the battery lasted longer.

Have you ever accidentally swiped on your notification bar? This will change the brightness and it's supposed to be some shortcut to change the brightness.

Same experience here. The auto-brightness really keeps the screen pretty bright at all times, it just dims it a little bit in dim lighting. If you set it manually, you can keep it dimmer than the auto-brightness will ever dim it.

[Q] Autobrightness OFF or ON?

Hi guys, i have an issue to fix..i leave the autobrightness on but often i get the display underbrightened, especially in the daylight..i don't know if is ok to disable the autobtightness because now the battery lasts for over 3 days!
thank you and sorry for my english

Autobrightness, when enabled, will take 2-4 seconds to adjust the brightness... so you feel its underbrightened...you can disable it and keep brightness maximum, then it will surely decrease the battery life

OP - also make sure you are not holding the phone by the ambient light sensor when the auto brightness is not bright enough for you.

As far as I know "Auto adjust screen power" will limit the maximum available brightness, so you might try to turn it off.

Do you know if the option to save energy for the screen actually saves energy?

where is it exactly?

One of the sensors to the left from the ear piece. If you grab the phone with your fingers on top and bottom, like in landscape mode, you can easily cover the sensor. Also some thick cases can cast shadow in the area of the sensor and throw off the autobrightness.
But yes, also make sure you have power saving mode off.

ok thanks to you all, i'll try turning down power saving..i'll let you know!

I'm glad I came across this tread as I noticed this too on my phone and started thinking it was a bug. I definitely am not covering the sensor and even placed the phone in direct sun light. I'll try turning the power saving off and see how it affects battery life and the brightness.

Power Saving Mode has nothing to do with brightness unless someone manually modify it.

I notice that if its the last of my battery the screen will stay dull

[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.

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).

Delayed Brightness Resumption

When I unlock the the screen, there is a few second delay in the screen resuming to the set brightens.
I am on auto brightness but there is a few second delay after unlocking & when its gone to the home screen.
Anyone have this or have I got a setting wrong some where?

Well it is set to auto mode, I guess it is normal to take a moment to measure the ambient light and set a determined brightness.

Ya good catch. My note 4 does this every once in a while too. My note 3 or note 2 never did that and it had auto settings too?

Having read the reply below yours, out might be nothing to do with auto brightess.

Is anyone else noticing this?

I also have noticed that mine does take a couple second to change the screen brightness when the brightness setting is set to auto.

Yeah mines still doing it. Might be fixed with an update. Doubt it though.
