Help - Screen issue on low brightness

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..

[Q] Youtube app, built-in auto-brightness?

while i was watching a video on Youtube on my Nexus 7, my connection was lagging so i paused the video to let it load, and the video had a bright white background while someone's in foreground talking. I noticed the brightness went down, and i freaked out thinking it might be my screen. But then i went back to the Android home menu, and i have a live wallpaper called "Rays of Light" which displays different colored lights moving on a dark/black background with little circles floating. I didn't noticed any brightness change, nor during browsing on websites, Google Play, or games...
Now i know Jelly Bean have auto-brightness enabled by default in the system settings, but i turned this off.
I do use MX Player as well, with the brightness set to go slightly up when watching a video, but i know i can turn this off (i just might, as i hate sudden brightness changes)
What i want to know is, does the Youtube app feature auto-brightness? and we just cannot disable it? I did noticed some brightness changes in other videos as well, like when watching a game preview.
For the record, i use Glazed Jelly Bean v2.1
thanks for your replies.

[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?

Blurry effect when scrolling on dark screens

Hello guys,
I was hoping to know if you also have this effect on your oneplus 5's.
The best way to describe is when you are on dark screens like twitter's night mode and you have some images with dark margins.
When you scroll up or down, does it appear a trail that disappears after some miliseconds? Like the screen refreshing itself making that trail disappear.
If you wanna try do this: twitter, night mode, follow for instance Nvidia (his logo is black and dark). Then go to home screen of twitter and try to find a nvidia's twitt. When you find it, look to his logo and go up and down. Do you notice something on the image itself? Like a trail of black pixels or blur effect that disappear after a while?
Hope that you can understand me.
Edit: don't know if I can post links here, if not please tell me that I remove it. This link is from Reddit where it appears an image where you can try this effect:

Edit 2: it appears that the effect is more visible on low screen brightness
Best regards.

Yes, I have noticed it as well though I also had it on my OP3. I think it is more of a thing with OLED screens and low brightness.

Yes, I agree. As this happened on my note 4 as well as my axon 7, oneplus 3 and oneplus 5
Yep, I've experienced that once. Dark purple logo on black screen
It happens on Amoled screens when the backlight is low. I have seen the same thing on all my Samsung phones as well.
I also confirm, low brithness OLED screen (samsung s3, s4, s5, s7, op3, op5)
oled are good for low battery consumption and high contrast ratio (blacks).
Otherwise, lcd pannels will be faster and more accurate with colors.
