[Q] Low brightness leads to greenish screen (8.4)

Hello,
I have found similar threads, but nothing seems to fit for my problem. If there is a thread for this topic, I hope the admins can move this to it.
I bought my Tab S 8.4 two days ago and was very happy with it (except the Play Store error DF BPA-30, which disappeared by now). The problem appears when I use the tab in the dark, after the second night I finally found out why: When the brightness goes below ~15 percent (automatically or manually) the display gets a dark-greenish tone. Full black and other strong colours don't seem to be affected.
A good example is a game I am playing: The red/blue/violet "nebula" turns into a dark green mass as well as the row at the top of the left. When I move around, the green mass "wobbles" too.

Is this normal?
Thanks for your advice!

I don't know if it's normal but I got the same thing. Since I keep my brightness low due to my sensitive eyes, I see it all the time. I have a 10.5 btw.
I haven't posted about it because I figure I may be more sensitive than other people.
Try this: if you have an LCD tablet or phone, place it next to the S on a table in a room with light. Turn OFF both screens. Move around so you are looking at them from different angles. With mine , about 45 degrees off axis, the S screen is clearly tinted a deep green (or if you prefer, the light reflected from the screen is green.) The other screen is black.

Same problem here too...

In my Tab S 8.4, the problem starts only when i shut down or restart the tab... On starting, the Samsung logo doesn't appear on welcome screen and then the display shows a homogeneous greenish hue, more identifiable in low brightness and auto brightness activated devices.. After a few restarts or shutting down the device for 5-6hrs, the display becomes normal on restarting... Interestingly, if you take a screenshot of the greenish display, the picture is perfectly normal when viewed in a normal device or laptop, thus making me believe it to be a display problem, most probably a manufacturing problem...

S9 screen suddenly bleached out, can't see anything

Hey all,
I was playing a game on my S9... Not sure if it's relevant but it was a boss battle with lots of stuff going on
Suddenly the screen became bleached out. It remains this way, even when I reboot. I see 3 colors. White, whitish pink, then whitish green. If you know video editing, just imagive you turned up the exposure by 1000% so it's almost just all whited out. I can see faintly some of the icons but nothing I can really make out. It seems to respond when I swipe as I see icons swiping around, so it seems to be a display issue.
I tried turning it off and on, but no luck. Also can't figure out how to do anything else with it because I can't see what's on the display.
Just wondering if there's a way I can fix it with a data cable to the computer, or if I'm gonna have to take it to phone repair.
Thanks

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.
