Help - Screen issue on low brightness - Galaxy Tab 7.7 General

Hi,
I would like to confirm there is somehing wrong with my amoled display.
If someone could download voodoo display filter from play market and do a quick test for me in the dark.
Open a picture viewer (I use quickpic) find some pictures, now turn the brightness down to minimum, open voodoo display filter and activate it and lower the brightness even more..
If you zoom or scroll between pictures, do you see black rings and all over the screen there is some odd texture?
This does not show up if i don't lower beond stock brightness, but at night i find the screen to shine to mutch..
Help
Ok im not alone, and found the ongoing thread..sorry for dblpost

Decrease brightness

Especially at night the screen of the phone is to bright for my opinion.
Is there any app to decrease the brightness of the screen?
Screenfilter
On market + free = Awesome
What a brilliant little app. That is exactly what I've, been looking for...
Superb!
The only remaining thing I'd like would be a way to turn the screen negative too, so that I can flip bright white web pages to being black background instead. Happy to have the distorted photo colours this would induce.
Although thinking laterally, the better way to solve this in the browser itself might be with local css style sheet over-ride, (if it was possible?).
The negative screen mode would still be useful to flip other bright white apps though. Of course ideally, the screen would be negative inverted as well as having this screen filter available too, so that you could convert background to black and still also reduce brightness of text.
Anyone know if such a feature exists, or could be created easily?
Thanks
Mike

You don't need an app, just run your finger left/right on the notification bar to increase/decrease brightness.

the minimum brightnes is still too strong in dark, therefore is screenfilter needed
Lowest you can get from the notification bar is down to 8%.
With a few different brightness widgets you can get down to 0%, which is still blindingly bright and not much darker than 8% to be honest... especially at night in a dark room!
This "screen filter" software lets you make the screen much darker than 0% by adding a grey lens over the whole screen for when you want it darker. It works really well.

Wow i didn know screenfilter exist. *Rushing to check it out*. Finally no more blinding light when in my bedroom.

[Q] Screen brightness variation

Hey guys. My first hours with the SGS2, and there's something annoying me that I couldn't find anywhere.
I'm getting screen brightness variation depending on the image. On darker images the brightness is higher than on brighter images.
I'm pretty sure this is not auto-brightness. I've tested with manual brightness and the effect is there too. It's almost like if there's not enough power for the screen, and when you have more bright pixels, the screen dims.
Has anyone experienced this?
This is specially annoying when scrolling different content, or even when you are on a predominantly white screen and the swype keyboard shows up, making the white area much brighter.
I'm currently on "Normal" on that stupid screen setting (I have image post-processing). Tried movie too, but still shows this behaviour.
Here are two photos using a Nikon D40 in Manual mode. Exposure has not been changed between both photos. I've put them side-by-side for comparision. Brightness was manually set on the SGS2.
Is there a solution to this? Hopefully it's not a hardware problem .
Hmm, can't post image links... Can someone please post them?

EDIT: FOUND THE ANSWER MYSELF
There's a configuration for Energy Automatic Adjustment (don't know if this is the right text as my phone is in Portuguese). Disable that damn thing .

[Q] Screen changes hue automatically? How can I turn it off?

Okay, so as the title says, the screen on my VZW GS4 seems to be changing the hue depending on what colors are being shown on different parts of the screen. For example, when I get a text and the little green icon pops up in my notification bar, the whites on the screen darken, and as soon as the icon is gone, they go back to normal.
The same thing happens in the youtube app. When playing full screen videos colors get lighter (and more unrealistic) and then when I click on the screen and the pause button and other menu buttons shows up, the colors darken and become more realistic.
I've turned Adapt Display off and this happens whether it in Dynamic, Standard, or any other of the display modes. This strange behavior is very familiar when the phone is set to the lowest brightness.
Anyone know why this might be happening or know a possible solution?
Menu | Settings | Display | Auto Adjust Screen
Tones
Just tried that and it still seems to be doing it. It'd quite annoying especially when in apps with dark backgrounds or night themes. Anyone have any other suggestions?

Auto adjust screen tone

Hi all,,
Are you able to see any kind of changes when this option is turned on?
I have searched, everywhere is written that white colours are more dimm etc.. but for me, when I flip for example from dark i-net page to Google page, I dont see any difference.
Sometimes, my screen goes dimmer while I am browsing i-net, but thats only sometimes. Shouldnt this work permanently? Also, when I display website with more pictures and than change to Google page, no difference..
Does it need more time to analyse pictures, or screen?

[Q] Ultra brightness screen sunlight mode and write on the rear of photos

I've noticed that in the sun some times and more with the camera, the screen will boost its brightness to a level we cannot select. it seems to even change the gamma of the screen where the screens look almost pink. But the result is a really bright and view-able screen in direct sunlight. Anyone know of an add to enable this via an app or some setting?
Also I remember with my Note 3 I could write on the back of the photos, is it not possible anymore?
I'm intrested to this.....but we have to find anyone who knows how to do that...
gekkehenkie11 developed an app for CyanogenMod called MDNIE Tuner which does that. Check the first post here: http://forum.xda-developers.com/note-4/orig-development/official-cm12-910f-910g-t3046965
Not sure if it works with TouchWiz...
