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 refuses to stay at down

I would like to have my screen brightness turned all the way down. This is my 2nd epic (1st one's menu soft key wasn't sensitive like the other soft keys) I go into the settings and set it that way as well as in the browser. I've tried having it setup with and without the power saving mode option selected, but no matter what, the screen brightness always changes to a higher setting on its own. I cycle through the power control widget and dim it back to 0 all the time but it doesn't remember the setting. I also notice that in some apps the brightness is raised i.e. market. What am I doing wrong? My bet is Samsung has an annoying glitch that they need to fix ASAP!

I noticed mine does that too. It will randomly be at a higher brightness setting. Also, the lowest brightness is WAY too bright! 0 on the epic is equivalent to 35 on the EVO.

Maybe when your pulling down the notification bar your sliding across on accident just enough to make it change brightness. Remember the brightness changes in your bar.....

i've got a vibrant but mine's doing same - hasn't done it that often, but does it
i found a small app for screen brightness control that displays the brightness percentage running as part of the icon, - just yesterday it had jumped from 11% to 52% on it's own
have no idea what gremlins are at work here

Coming from WM I was not aware of this gesture. I did notice sometimes when pulling the tray down it would do it. I need to read an android for dummies book and see if there's any other hidden jedi mind tricks that can be done.
I compared my brightness at 0 to an iphone4 all the way down, EVO, G1, Hero, BB Bold, and my former WM phones and the epic is way too bright at 0. I wish there was a way to keep the brightness set to the same setting when the screen dims in some apps, that would be ideal.
Good to see I'm not the only one with this issue and definitely getting a screen brightness icon in the notification panel will be very helpful to track samsung's shiesty shenanigans!
P.S.
The screen brightness increased on its own while typing this message from the xda app....

Doesn't the epic have an ambient light sensor for screen britness control?

Yes but sometimes that's too bright, I'd rather have it set all the way down and stay down and raise it as needed on my own.

This is when a custom rom will be handy... no other way to get around it I don't think. I use adw and have my swipe down gesture for notification bar. That way I never have to reach all the way up.

Brightness control
There is a setting under Sound and Display > Display Settings, called Power Saving Mode. I disabled this along with the automatic brightness control and my screen brightness hasn't changed since. Not sure if this is your issue but couldn't hurt to try.......

He did say he have used this setting before.

There's the power saving mode AND there's also the automatic brightness control. Two different settings. I turned both off and I haven't really seen the brightness change since.
Incidentally, disabling the automatic brightness control (in the brightness menu) has greatly improved my battery life.

Did you read the first post? It said he did BOTH.

Fixter, you beat me to it.... We need to find a way to get the phone to stay dim like when the XDA app is searching/refreshing. This would be ideal if that would be the baseline for 0% brightness. I hate how the Eclair browser's brightness 0% is one tick higher than using quick settings to turn the brightness down. Too bad I don't know how to develop, as this would be the first thing I would fix!

I think that it's easy to accidentally change the screen brightness when pulling down the notification bar.
Once I realized that...I haven't had any problem keeping my Vibrant at minimum brightness.

I have figured it out been having the same issue since I got the phone was driving me nutsbut I have noticed two things one if u slide notification bar down a lil then slide left it lowers and right it highers and two sumtimes when sliding the notification bar down I sumtimes slide over light senson snd if hand is oily u produce a smudge over it causing it to lower brightness or higher

dimming backlight

Is it possible to dim the TF backlight further when the device is rooted? I personally feel the minimum setting is stlll somewhat too bright for me when in the dark. It would also save some extra battery life i guess but that`s not the main issue

as far as im aware this is not been achieved yet, however i believe the app screen filter is succesful for some but never tried it myself

Oh this works like a charm thanks! Single tap dims the screen to the preset brightness level i can decide upon myself. Way darker than stock

glad it works may try it myself now lol!

That is a great app. Now if there was only a way to dim the arrow keys too.

Anyone elses play do this

So I keep automatic brightness on but I think my play may have a problem. I turn the backlight off and sometimes my plays screen flickers brightness- like it's automatically changing the brightness but it's going back and forth rapidly. I don't know if it is a fault or just that I'm not keeping the phone steady enough. Any assistance?

Turn automatic brightness off temporarily and see if it still does it?

If your blocking the front camera then it will do that. That's how it uses the auto brightness.

Thanks guys. Will see

Is this normal or problem? Brightness.

Good afternoon,
I do not know if it is something normal or it is a real problem that requires technical support. The case is that I have the mobile without automatic brightness, and when I set the brightness to very low levels, when unlocking the terminal, when you turn on the lock screen with the wallpapers, it appears as a slight flicker of the screen, thousandths of a second, almost imperceptible if you do not stare. Something like when you start to light a light bulb until you get to have light at all, but with a very slight flicker.
It is not an extreme flicker that completely turns off the screen or any of that, it may even be the operation of the brightness sensors (which happens to be strange because the automatic brightness is off), but I worry that it may have more problems in the future. Also I have noticed that having the brightness to the maximum of half of this problem does not occur, only with low brightness. There is also no blinking once unlocked using the phone itself, everything works perfectly. It is as if the lock screen was automatically adjusted when unlocked.
Should I contact technical support or just foolishness of mine?
Regards and thank you very much in advance.
PD: I have EMUI 4.0, NXT L29 with b192

Maybe you can upload a video so we know what ur talking about.

I think I've actually noticed something like what you're describing in my device. In summary, ever so slight flicker of brightness when display is on low/lowest level with automatic level off. I assumed it was normal

I have tried to record videos, but it is very difficult to appreciate.

I also think it's normal. It's like an automatic contrast adjustment to accommodate the eye to the screen. I think it's a matter of the IPS NEO screen.

Does anyone else have this?
