How to Fix Blue Light Filter and Screen Mode - Samsung Galaxy Note 8 Questions and Answers

Apparently my phone won't allow me to use blue light filter and screen mode settings. The on and off switches can't be tapped.

Blue Light Filter and Screen Mode options are disabled if you've got 'Greyscale' or 'Negative colours' enabled under accessibility settings.

Color adjustment will disable too

Mine are greyed out as well and neither of those two things are turned on.
**Found the problem. It was screen zoom setting.

[REQ] SIMPLE backlight app

I'm looking for a tiny little app that will toggle the backlight setting from current setting (mine is auto) to the lowest setting (dim 1).
I am using a key mapping program to map out the hardware keys on the front, and one function I would like to have is to be able to EASILY switch the backlight to dim 1 and then back again to whatever setting I had it at before.
I like the auto adjust backlight feature built-in with WM6.5, except when it's pitch black (because the lowest it will go is 3 IIRC). Due to the light sensor detecting no light when some light is still present, auto dimming programs (such as Lumos) don't accomplish my ultimate goal. So I am looking for a way to be able to set it to 1 only when I want it (like at night when there is no other lights around).
BUMP it to the top.
Anyone?

[Q] Disable Xperia T Auto Contrast Thingy Magigy?

Hi guys, I have a Xperia T and recently disabled DLS which drastically changes the brightness of the picture you are looking at depending on whether it's light or dark. If it's a light picture then the brightness would increase and if it was a dark picture the screen would go dark.
Thankfully DLS is easy to disable by editing the pre_hw_config.sh file in root>etc. However, there is still a feature that adjust the contrast automatically, which is kind of annoying when watching vids.
Is there anyway to disable this feature? I tried disabling the Bravia Engine but that has no effect and it's also not the adapt to lighting conditions in the brightness menu.

[Q] LED colour when gets notification

Im just realise that on my whatsapp i set the colour of notification to yellow, then when i get new message, its not blinking yellow, only white colour (in STAMINA MODE)
then i try to turn off STAMINA MODE, it can blink yellow LED, so anyone know how to override the setting so that it can blink different colour in STAMINA MODE? i try to exclude from STAMINA MODE, but sadly it dont turn yellow. by the way, im using stock rom 4.3, fully root
I use a 3rd party app called Light Manager.

It allows you to change notification light for different apps as well as blinking rate. It works with Stamina mode enabled and not added to its white list.

I already try it, but when STAMINA mode, the colour of LED change back to white. when i off the STAMINA mode, its blink back to normal
Are you on 4.3? I just enabled Notification access for the app under security in Settings, and the app works fine in Stamina mode.
If that don't work, I can only suggest maybe give Light flow a try.

i think u have played with some option from the developer mode go there and try to turn things off and see how that goes
if not then a factory reset could do something for u if its a developer option thing

Firstly what firmware version you on? Maybe more details would help
1. I don't get a screen full of green, but the screen is slightly brightened with a greenish brightness. I assume this is the issue. Most phones (inc Oneplus phones) with optic FPS do this as the bright green FPS light also partly turns on other oled pixels. Some other manufacturers lower the brightness of the finger print sensor light, which then has the effect of inaccurate print reads. I dunno, I like how fast the FPS unlocks the phone, its one of the quickest - if the slightly brightened screen is the sacrifice, I'm ok with that :good:
2. I can't replicate this
3. I can't replicate this
4. Why do you need to disable these core google apps?
5. Red tint is hardware - its been slightly improved with the latest WW-16.0631.1910.35 firmware, but this oled screen has a dominant red gamut - every oled screen has a dominant colour (either blue, red or green) so just have to deal with it. :good:

Question Brightness "issue"

Hello. I seem to have an issue with the brightness. Even when on max, white colors look yellowish. Like there's a yellow tint or filter. However when I open certain apps, for example my homebanking app, when I press the Fingerprint button to read the fingerprint, the brightness instantly goes back to max and with a vibrant white. As soon as I enter the app, that yellow "filter" comes back.
Generally it has that yellow look on the whole phone, but like I said, when I open certain apps it boosts to that bright white, but then returns back to the yellow look. Its like there is a sudden change of brightness and then returns back to "normal" yellow filtered look.
Is this a bug?
Disable "conforto ocular" and "Tom natural".
