Having problem with auto brightness

I got note 3 days ago. I notice that The brightness always jumping, sometime happen with open application with white background.
Wonder any one have the same problem or just me. I'm on the KJ4 Kernel

I have the same problem

I got the same kernel but without the auto brightness jump you are experiencing, unless I move my hand over the camera.
I suggest goto Settings --> Display and un-tick "Auto adjust screen power" if it's on and see if that makes any difference.

Auto-brightness is hopeless anyway, turn it off, as well as the setting Bigmile mentioned. Then, to make quick on-the-fly adjustments to your Note's brightness long press in the notifications area and slide left and right till you get the brightness you want. Much better way IMO.

Galaxy S and SII were the same, but still surprisingly little known feature.

Just switch from iPhone. IPhone have perfect auto brightness adjustment. However I still like the note very mush as it have nice BIG screen.
Hope it will fix in future update anyway.

define applications with white backgrounds?
if youre referring to the browser, it has its own independent brightness setting that can be adjusted inside the browser.

I call my self an enthusiast and I didn't knew that? Well, the saying "You learn something new every day" is proven once more.
Been using android since launch(I guess it was implemented on GB?) and I admit I NEVER thought of sliding the notification bar icons neihter left or right in the way NZtechfreak suggested.
It's possible that I might have done it by accident, but even IF I did, I did not even noticed it. You got my Thanks.

Crap LED notifications and sound.

I'm on my second N4. The first I didn't have long...stolen... but I remember how non existent the LED notifications were and that the volume just wasn't high enough for in car voice navigation. The rest of the phone was fab so I figured I had a faulty LED light and accepted the poor sound volume. Alas I didn't refer to this website because if I had have done so, having read the same complaints in many postings, I'm not sure I would have re-ordered. On the basis my new N4 would at least have a working LED I re-ordered and you guessed it....the same issues are present. Yes, I can install Light Flow but that is still a fix for a problem that I should not have to fix. Secondly the LED is so poor anyway that it may as well not be on the phone. The wife's iPhone 5 LED is positively like an aircraft strobe light by comparison. The N4 sound also is still not loud enough. Many people overcoming these issues by installing apps is a sign that LG need to address them properly either via a software update or on the next phone. One last whinge....even with Light Flow, I still don't get notification of emails. These two issues for me, LED & low sound, really let down what otherwise is a first class phone. Now I'm wiser if I need to replace again, I'm afraid it won't be a N4.

The iPhone 5 or any iPhone for that matter does not have a led notification light.
It does have a option to use the camera's led flash as a notification light though. Which is what you are seeing. And its not the same thing.

You might want to check out the thread on LightFlow in the apps forum, the Feb for the app hangs out there. LightFlow works perfect for me, though I don't use it for email notifications.

Lightflow works perfectly on my N4. I LOVE the notification LED on this phone .. All the colors available + the grainy,subtle way it glows against the all black front is just awesome !

Gpad screen gamma is too low

Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.
https://imageshack.com/i/nf96iaj
On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.

That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

I hope @dalingrin can cook something up to address both. He said he was going to work on something.

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Gald to have helped would you be willing to try the kernel for the stock LG ROM?

Please take a look at the images below and compare
The tablet on the right is running my kernel and the left stock
You can see the differences on the first image as the deepness of the blacks
and on the second the highlights on the white

I just about to get this tablet, then i so this problem... ?

T2wake

Just watched a review of the z3 compact, and under the display settings there was an Orion for touch 2 wake. Awesome!

How about the notification led that everyone is crying about? Was it a bar or just 1 led?

My z2 tablet has this and it works nicely by only gripe isI'd like to be able to change the tap frequency as it's a little fast for me so I get it wrong on occasions

It is just the LED...that is the only notification...I even punched in the diagnostic code and fired up the notification test, which showed only the LED light at the left corner..
Not a deal breaker though...

Of course not a deal breaker. But the ZR light is so pretty ?...

I prefer active display rather than any notification LED.
Of course have to await custom ROMs.
But IMO I would prefer no notification light at all.... Therefore the smaller traditional led light would be preferred

Active Display kills battery if it's not using an AMOLED display.

It doesn't kill battery at all on my z1c. Your mistaken there

Have you done a percentage-per-hour battery drain test on Active Display? I've never had a phone without an AMOLED display, but I still can't see how this can be true. An AMOLED display literally only lights up the pixels used for the notification, while an LCD display lights up the whole screen to "render" the black as well as the white. It will definitely use more power. Even if it's not noticeable with your usage patterns, it will likely be noticeable to someone else.

Perhaps.
As a gage.... I get the same battery levels for both LED or active display.
Subsequently active display on my z1c does not drain faster then LED usage.
%/h on PAC ROM for z1c with mosh kernel and mpdecison and active display drains at 2-3%/h

I have the feeling that it takes more battery if T2W is enabled... or did you guys experience something else?

I disabled this feature because it activated screen in my pocket.

it's a feature of the Snapdragon 801, so i'm assuming that power efficiency with T2W is baked in. i've found that battery life is already ridiculously awesome with T2W on -- if you want to increase battery life, you'll get better results with Stamina Mode and selective whitelisting.

ambient display brightness adjustment

ambient display is, for me, in many situations, too dim, or it turns off in dark as it says - is it possible to disable this i noticed samsung and huawei phones don't have this issue and their always on displays are nice and bright always

Me to, in dark situations, too dim, or it turns off when you go from light to dark, think that adaptive brightness have problem on all xiaomi phones, don't know is this problem with MIUI 10, MIUI 11 or something wrong with android 9, we will see what will be with android 10.

Well i bought mi to have at least some notifications as oneplus does to have any, but i think, i would be better of with oneplus as nothing when it is not supposed to work is better then nothing when there should be aod, but it is mostly to dark it is impossible to see or just plain off.
Well to be honest, only Samsung was where I was AOD to be really working, not even pixel or huawei was without issues. So I wonder where to go next time - I guess apple, as in EU samsungs have weird power hungry chips.
Tough I wanted full display without holes and I got it and it look really nice, shame that other functionality of the phone after update to miui11 is gone.

I have created a work around fix for this little annoying problem.
I used Tasker and made 5 profiles that reads Display Light values and adjust the Display Brightness .
I have set Auto Brightness OFF
Check it and give feedback if you find it useful.
I attach the tasker file to import it

So is there a solution for this nonsense issue already? Googling around and can't find a fix for over a year now.
I did not notice this issue on any other xiaomi phone, including mi6, mi8pro, mi9se.
This is so annoying, I want to throw this phone in to a wall at times. But then I remwmber how much time it takes to fully set up a new one.
