Screen goes monochrome(black/grey) before it turns off - Samsung Galaxy Note 8 Questions and Answers

Title,
Is this a thing w/ OLED screen?
It loses colors just before the screen goes off for a brief second. Something that doesn't really bother me, but enough to annoy me.

I was able to turn this off in developers option by turning the animation to none or zero whatever that option was.

You are absolutely right, that does the trick.
I was thinking that would solve the problem, but didn't actually think it was it.
Thanks ?

Screen turns grey just before it actually turns off
Im having the same grey screen issue on my new Note 8. Can you explain where and how I can change this? Thanks a lot.

That is really odd, I have animations to 0.5 and the screen just goes off, no color changing to gray scale, 950F 128 GB

All three of thr notes ive come across go monochrome , normal.

Green vertical line when switching off the display

Hello everybody, I have the following "visual effect". It happens roughly 50% of the times the display switches off. It doesn't matter if it is by it self, by the power button or by a software button. In the very moment when the display switches off, a greenish dot in the center of the display flicks for a split second, along with a same color vertical line trough the whole screen. Obviously it is not supposed to be this way Beside this issue, there is no other problems with the display or the phone( for now). What do you think about this? Thanks in advance
Sounds like a screen off CRT effect, check you tube to see if that is your problem
Isn't the CRT effect a horizontal white line ending up in a dot?
I genuinely think the OP's screen may be defective...

do a lcd test and check if all pixels are working ok
Unfortunately it is not a CRT effect, although it looks a bit like it. The difference is, that the line and the dot( little spot) appear simultaneously for a fraction of a second. In a daylight it is hard to see it, even more it happens just 50% of the times, but not every other time. Its somewhat random.
The *#0*# test do not show much. No dead pixels. On blue you cant see anything, on green and red I think I see a little bit darker spot in the center of the screen( where the dot/spot appears), but there are such darker sports and elsewhere on the screen.
BTW, I noticed recently, that when the screens dims a bit shortly before switching off, this dimming happens not so smooth. How should I say it... it happens on a several steps, although the whole thing is done in less then a second, it is not so fluid. Is it supposed to be this way?
Thanks for your help guys
have u tried flashing a different rom stock
I am on the latest German stock 4.0.4, tried several others, including 2.3.6. .Currently with Hydra kernel. No difference whatsoever. I think the auto-brightness doesnt work so good. When set on fixed value it dims more fluidly.
if u on stock rom and not rooted then take it to a service center

[Q] Screen won't switch on and neither will the charging led

Hi guys,
My mobile phone seems to have a not working screen. The weird thing is that the backlights work and I can connect via adb, but the screen and the charging led will not.
Do you think it could be because of a faulty or not connected wire? I want to make sure that changing the screen would solve the problem before buying one.
Thanks!
Update: I just noticed that the screen is on but extremely dim. It´s not possible to see anything at all.
Could be LED backlight
Does moto logo show, when rebooting?

Yes, the mobile works normally. It's just that the charging led (the one on top of the screen) won't work and the screen is extremely dark. It's almost impossible to see anything unless you are in a room with just a little light.
The brightness is set to 100%. It's probable a faulty screen or a loose connection but I would like to find a way to know if that's the case

That was not what I was asking, is the moto logo as bright as it should be when rebooting?

ah sorry. I see what you mean. No, the screen is always so dim that it's really hard to know if the mobile is rebooting.

so it's not a screen setting or bad app, and not likely a software issue.
It could be a bad screen LCD connection, but guessing the LCD screen needs to be replaced.
can buy a new LCD for about $30 on ebay, but maybe more trouble that it's worth

could have someone else fix it

or it's time for a new phone
I will try to fix it myself. The price of getting a new one will be similar to the price of sending it to repair so that would make no sense.
Thank you very much, sd_shadow

Weird green line

There is a vertical green line near the right side of my screen. I don't know how it got there. I was listening to music and I turned the screen on and its there.
I'm on lightrom 5.1.1. I flashed it the other day and no problems. I would post a screenshot, but it doesn't show in them for some reason.
If it doesn't show in screenshots, that usually means its hardware as only software issues would show in a screenshot. Can it be seen during boot on the coloured parts?
Yes it can.
It's weird because when I turn my screen off, its the last thing to go off after black screen.

Definitely sounds hardware. I'd return tonarock and if its still present, which I assume it will be, RMA

On the boot animation but not showing up in screenshots?
If it doesn't show up in screen shots, then it's hardware related. Screenshots take a picture of what you see software-wise. If your display completely dies, your phone would probably still turn on and allow you to do things if there were only a way to interact with it. Seeing that the green bar is always present, except in screenshots, it's hardware related. I'd RMA it or return it, depending on when you got it. First though, flash back to stock everything. They might blame you for the hardware fault. Lol.

Blue light filter

Just noticed, the blue light filter takes a few seconds or more to engage after screen is brought back from standby mode. Pretty irritating.
Example viewing a page within Samsung browser, screen times out ( has to time out )then I press the home button to turn screen back on, blue light filter is off now for a good few seconds or unless I go into the settings screen.

I thought it was just me. I looked around to see if anyone else was having it in other threads but I'm glad I'm not the only one having this issue. Mine is really delayed that I need to turn it off and turn it back on. Sometimes I wait over a minute til it activates so I just end up having to toggle it off and on since it's faster... Unfortunately

I have this issue. Also, even with blue light filter turned completely off, it still engages at dark. Anyone else?

LG V40 screen constantly dims..Auto brightness off

Hi,
Have had the V40 since release date. Feelings are mixed bag of frustrations.
My screen is constantly dimming and then going bright. Screen brightness is off. Is there anyone else experiencing this? Can anyone help?
I want to add this.... This problem seems to only happen out doors..bright sunny conditions....
Thanks!
I have the same thing, but it's a dimming before the screen goes dark ... it never comes back on brighter unless I touch the screen to keep it active, if I don't touch the screen it soon goes black.
Play with the screen saver settings in display, setting them to different times to see if that's your issue.

I see what you're saying. However that's not what I'm taking about. It's almost like a flicker... Almost like the screen is overheating and the screen is dimming to protect it.......
