Display can't differentiate between black color, and dark colors? - Samsung Galaxy A70 Questions & Answers

I was watching a video on my PC's LCD screen, but I decided that I would continue it on my A70 instead.
I knew that I'd get different colors because it has an AMOLED display, but I didn't think that most of the dark areas in the video would get turned off! The screen literally turns off the dark colors even if they weren't totally black! And the more you dim the brightness of the screen, the more pixels it turns off! This can also be seen when you put a video lock screen that has dark colors and you dim the brightness. You're gonna see that most of the pixels turn off, and the colors of the remaining pixels will get distorted.
I've faced this issue on the A70, but on my brother's A50 the display is totally fine.
*Current lock screen wallpaper that I can clearly see this issue on: Decor (animated)
PS: My phone previously had the touch panel issue(where the screen feels sluggish when scrolling, and would sometimes click on stuff by itself), which didn't get fixed with the OTA update, which forced me to go Samsung's customer care, which they told me that they need to remove the firmware altogether(because the OTA update didn't install successfully), and then flash the already updated firmware, which indeed fixed the touch panel issue to a degree(it still happens but not as frequent as before).
Do you guys face this issue, or is it just my device? I also sent a message to Samsung explaining the issue through Samsung Members app, but they told me to go get the correct firmware flashed.

Screen flicker test

Hello. Since getting my new HTC M8 the other day I noticed that the screen can flicker for a fraction of a second when in the setting menu.
The issue really comes to light when you use a screen filter, I use the app that is literally called screen filter. If you set the app to about 20% and then you go into the settings menu you start seeing microsecond white flashes when backing out of and entering new menus.
Does anyone else experience screen flicker on there M8. I like to know if its my phone thats the problem or the screen filter app. If someone wouldnt mind testing my steps above out, it also helps if you have the screen filter on in a dark room as the flashes become even more pronounced.
Thanks

Do you guys face these display issues in your devices?

A70's display treats dark pixels as if they were completely black, and turns them off instead of dimming them. Which leads to difficulty and inability to see dark things properly + distortion of the displayed thing (especially on the lock screen) because a lot of pixels are turned off.
The device has already been updated to the latest software version in Samsung's customer service center.

Test your device at night or in a place with dim lighting.

Yeah, that's how AMOLED works. And no, I can completely see properly dark things.

I know how AMOLED works, it's just that it's not working correctly. Check out the pics in the link, the screen changes the colors, and turns off way too many pixels.
You have more issues besides pixels turning off. Looks like posterization as well.
I don't have those issues with mine.

If you know how it works, then take your phone to the service centre as probably you have the warranty.

They told me there was nothing to worry about, so I guess that's that.
yes i have these problems too on the lock screen majorly i think its a step by the software to save battery. I had these problems on my old note 5 too.
Happens to me too.. Dark grey colour turn pinkish on lockscreen..

Replaced screen - now it auto dims so I can barely see the screen and I can't adjust it

My wife cracked her Redmi 7 screen so I ordered a replacement screen+digitizer+frame from a reputable seller on AliExpress. I followed a guide to the letter and made sure not to damage anything while disassembling, and the re-assembly with the new screen went smoothly.
When I power on the phone the Xiaomi logo comes up nice and bright, but it then auto-dims in the usual way as it loads the system except it dims to an extreme level. I mean it dims so much I can only see what's on the screen if I go into a dark room/closet. When the system loads I can navigate menus normally (as long as I'm in a dark room) but changing the brightness setting has no effect. Turning on/off auto brightness does nothing either.
It doesn't seem like there's anything wrong with the LCD, because if I reboot to bootloader it sits there with the Fastboot logo and picture at full brightness until I turn it off. I took the phone apart again to check if there was anything obstructing the light sensor and I can't see anything wrong with it.
Has anyone seen this before?
Thanks

Do you have some tips to avoid screen burn on amoled?

Hi, I'm a new amoled user. I've bought a op7t and I'm pretty happy with it.
But I read everywhere about screen burn problems.
I know this is a tech issue with amoled. And this is my first amoled display.
So do you have some tips for me to avoid screen burn? Someone talk about notifications area? Using maps (absurd), time-lapse and fingerprint is that all true?
Thank you in advance
I'll make an effort of sharing my experience with AMOLED screens and what caused the burn in
Persistent screen elements like the status bar icons and navbar at the bottom left permanent ghosting on the screen. The causes I think were the increased screen timeout (30 minutes) and using GPS with the screen on as well as having a navbar that wasn't translucent or changing colors.
Mind you this happened over a period of 3 years and I didn't notice anything unless I really looked for it. I watched videos and the ghosting didn't affect anything. Only on bright backgrounds such as a white screen or gray did it pop up. Not enough to be noticeable or hinder my viewing experience and I am very particular about that.
Tips I've since been using after getting that experience for my new phone (7T 1907)
1) Keeping screen brightness under 50 percent unless absolutely required
2) Quickly switching between various different apps for a couple of seconds when using my phone for a long time
3) Keeping the screen off while using GPS and occasionally turn it on for looking at directions
4) You can turn off status bar icons from inside the settings to prevent them from causing the burn in under the status bar settings
5) Not increasing the screen timeout to anything over 2 minutes
This is what I know and have researched about OLED screens in general. If you have anymore questions I'll be willing to help.
It has been over five months since I got it and replaced my old phone. So far so good

Question Screen issue or software bug?

Hi!
I have received my Red Magic 8 Pro and immediately noticed something. The selfie camera is visible if the background behind it is simple. For example just a simple white or gray background. Depending on movie sometimes it also becomes visible under cartoons like Rick and Morty, however during normal movie I cant see it.
Is this normal for this phone?
Also, the software which handles the pixels in front of the camera sometimes can become bugged and a visible line is displayed. I can reproduce this issue by pulling down the notification bar and holding it at 1 spot.
Does everyone experience these issues ?
That's normal, especially if the screen is on 120Hz, and at low brightness. It's the so-called green tint issue.
