Black pixels on AMOLED screens (s8) - Samsung Galaxy S8 Questions and Answers

black areas on amoled screens do not light up, however is this the case for all screen modes on the s8 (basic, adaptive, etc)
In other words, are the blacks on all screen modes turned off, or is this just for one specific screen mode?

Did you make sure to turn off "Auto adjust screen power"?

I was a bit quick to judge. Now I did set both devices equally did a synchronised screen test, and I covered part of the Note to equalise surfaces.
They look equally bright only the white is notably different to me, a bit pink on the Note and a bit blue on S2. The 'blue white' looks a bit brighter on the S2.
display mode
you do know there is an option to chosse display mode in the screen settings. it allows you to choose movie, regular, or vibrant. these settings could affect the white looking pink. try different modes and see if the white is changed any.

I have no issues with my Note display colours, for me it's great. On request I compared to my S2. Display mode settings on both phones where set to standard to compare

A way to reduce backlight brightness beyond default settings?

Hi peoples
Does anybody know of a way of reducing the backlight brightness below the stock settings?
I've tried various screen filters, such haxor Screen Filter, but these apps are rubbish IMO. All they do is apply a grey transparency filter over the screen, they don't actually reduce the backlight brightness The result is a trick, the screen looks darker but it's really only because the white pixels are made grey. The problem with this approach is that it messes up the contrast and colors, and gives a washed out look.
I like to sometimes use my N10 in a pitch black room, which needs a very dark screen. My old Galaxy Tab 8.9 was good for this, because the backlight was able to go much darker than the N10. The thing is, I know the N10 hardware is capable of having a darker backlight because if you don't touch the tablet for a few minutes, the screen first goes dim before it turns off.
I would like to be able to manually activate the very dim screen setting, or better still, have a lower brightness range available in the brightness settings.

Try to use Movie Screen Mode (Settings->Device->Display->Screen Mode). It helps.
Technically Movie (Cinema) mode will make the screen even more Yellowish than Adapt display or Standard.
The only thing you can do is install the app Screen Adjuster app and turn up the Blue channel, that will make the Yellowish tint less visible.

Nightclick & LCD vs AMOLED

Last night, I went to use my night clock app with my new LG v20. On my Note 7, the screen was totally 100% black except for the numbers.
On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.
(Note, this includes the 2nd screen which was also lit - and I had the brightness at 0%).

BTW, this may need to be a separate thread - on my phone I notice that the auto-brightness tends to be too dark. Any way I can adjust it to be brighter when in auto mode, or should I just go to manual ?

Try turning off second screen and see what your results are.. Second screen has a seperate black light that slightly bleeds out to the rest of the screen. It was horrible on the V10 but much improved on the 20..

The night clock app has the option to turn off the notification, which also turns off the 2nd screen.
...oops. It did, until I followed your suggestion in the other thread about the more setting to enable time/date when in full screen or notification bar hidden. I'll have to get into the habit of turning *off* the more setting at night.
(Either way, doesn't help with the slight gray background color. I can probably just get used to it as long as I'm not damaging the screen by having it slightly on all night. I need to google if LCD screens have burn in problems I guess.)

Maybe I should just start pm'ing you all my questions

Use comfort view on low or medium. Will help lower the ~9000K color temp some and help blacks a hair. Faint glow is typical on LCDs. Higher quality LCDs and higher quality led's can help. Lg skimped here. Sucks they didn't even give us color modes to pick from. The colors are waaay off. But using comfort view dims the blue pixels and helps considerably.

That's just how LCD works, they need CCFL or LED back light to lit up the screen, it's not possible for it to be completely black while turned on. With AMOLED the individual pixels can turn off itself which is why the black are blacker on them. OLED screens also have very high refresh rates which eliminates flickering, this is good for people who are concerned with eyes health.
Lcd doesn't get burn in, but it can get ghost image retention. It was f***ing horrible by the end of my V10 usage.. Never had the problem on the G2 3 or 4. Just the V10, even after factory resetting.

Had the same issue my V10, that is my biggest V20 concern. . My v10 was not even a year old.
I get the engineering and cost reasoning, but not sure I like the lcd screens.

Oled problem?

Hi, I moved from OG pixel to pixel 4 and noticed that screen has problem. On 100% on brightness when opening totally black picture screen is not totally turned off and when touching it screen greys out a bit. Is it bug or hardware issue?
Can anyone check it on own device?

I have noticed the following: When screen brightness is 50% or less and I touch the screen such as typing on keyboard, the screen flashes very slightly on every tap. It feels like the screen draws too much power and battery is low. I went to Verizon store to check display unit and it did the same thing. Maybe your issue is similar

I didn't contact Google because the store model had the same thing. I just tried to troubleshoot what could be causing it and seems that when I disable "smooth display" in settings>display and then tried to reproduce the issue by typing on the keyboard and the screen doesn't seem to flicker anymore.
Try to disable the setting on your phone and see. This might be a software issue then.
I found similar thread(you are probably on it too) on Google community site and replied to that thread: https://support.google.com/pixelphone/thread/22331033?hl=en

You are right I disabled smooth display and it stopped flickering but there is one more thing when brightness is on 100% and opening totally black picture I can notice little lightning of the screen in corners it means that pixels are not going off like it should be on oled screens. Could you please check it also?
It could be checked only in the dark daytime it's not noticable

Alright, I found a black image with only a small moon in the middle. Did the test on 100% full brightness but don't see any pixels on the screen. Check my image(attached) and compare.

Yes, of course. I turned off the lights. I have seen issues where some phones had some light seeping through(light bleed) at some edges. Is that what you see?

Picture was taken from og pixel with night sight mode, It's not such noticable from eye

It is difficult to understand anything from the picture. Try some display test apps. Check to see if you have something installed such as 3rd party theme or an app that interferes with the display of your phone. Also if you can compare your phone with the one from the store.

In my country I have no local store and I can't check it. I have nothing installed yet in my phone.
Found amoled screen test picture when openig it in totally dark situation I can see slight grey backgroud at the bottom corners.
I just need someone who can confirm It's only my phones problem or not (

If it is in the corner(s) then it is light bleed. The screen is good and it is just some screen backlight being seen through the frame. At least this is how I understand your situation from my previous experience.

So can you notice such light bleed on your pixel? or it's on my pixel only?
