Anyone else have screen-burn in? I always use the ambient display. Recently I've noticed burn-in from the ambient display. Not noticeable when the screen is awake but definite discoloration in ambient mode.
All OLED displays experience burn-in. This is actually in the news right now due to the Pixel 2 XL and iPhone X. The only way to avoid it is to turn off the ambient display.
There are ways to mitigate burn-in to an extent, but it increases wear on the display.

Iam not sure if any of the one x+ owners out there have experienced this problem. When watching a video, for example using the YouTube app, depending of the type of scene being shown, whether it be an indoor or an outdoor scene, the phone has this gradual change of the the screen brightness level. Now mind you, the display brightness is set to about 15 to 20% and auto brightness is off. Its noticeable as the phone seems to take a second or two to adjust to the new environment within the video.
The dimming issue is also noticeable using the browser, especially when viewing a very dark image and then switch over to a bright one. The phone dims a little when you display the dark image and as you transition to the brighter image it will slowly brighten a little.
This problem can become distracting especially when watching videos that have a lot of transitions between light and dark scenes.
Its less noticeable at brightness levels above 60 to 70%, but i find using the phone at such high brightness level at night irritating to the eyes.
Its annoying since the screen doesn't stay on one consistent brightness level. all the phones i have used before, S3, EVO 3D, S2, NOTE don't show this problem. it doesn't matter what scene is being displayed on the phone, they all maintained constant brightness levels
I would be interested to know if its just my phone that does this or its common issue
So many views but not even one reply...surely i cannot be the only one who noticed this
Hey, just bought the G5, and amazing phone so far, everething works perfectly, but one thing that concerns me is the screen isn't bright as other phones. I am coming from the G2 and clearly the screen is superior by far but the brightness is just not as the G2's. I know the G5 has some trick that makes it go extra bright in sunlight in auto brightness mode but under regiular light is just dim. I am sure its a software issues as I checket the screen with a flashlight lighting directly to the light sensor and it goes extra bright. Anyone else has this issue?
Are u sure that opx is true black amoled??
What if I say you ... that ..It has a backlight ..
Wanna verify?
Important: make sure u have brightness slider to near low levels. This backlight is not seen at high brightness levels.
Download a gallery like quickpic that lets u open a picture in Fullscreen mode so that picture fills entire screen.
Make a bmp image in ms paint in windows and fill it with perfect black. Or download from some website with hex value coding -enter zero for all numbers
Now load this picture in quickpic or any other Fullscreen gallery.
Switch off every light in ur room .make d room jet dark
Wait a few seconds for your eyes to adapt to darkness
U will see the backlight instead of black.
For more easy recognition see in peripheral field of vision, where low light vision is good. (Focus point of eye doesn't have low light vision ,am a doc.) (see somewhere else, bring in the phone into vision filed)
If u think the gallery is d problem.
Do this same thing in any other amoled phone. You will know the meaning of black.
(I did in Moto x ghost )
It's not a backlight. No AMOLED screen uses a backlight. That would defeat the whole purpose of AMOLED.
What happens is, even if the pixels are black (switched off), they are fed a tiny amount of voltage from the motherboard to allow quick switching of colors so they are never completely turned off. As a result, even when displaying black they emit a very faint glow.
I'm not sure if this only happens on pentile displays (like the one in the OPX and most Samsung phones) and I can't verify since the only AMOLED devices I own are pentile, but my Galaxy S3 Neo also has this "problem". Personally I wouldn't worry too much about it, since even with the glow the blacks are WAY deeper than any LCD display with a backlight can produce.

Thank God man.
I thought my phone is fake display.
Ur reply is proof that knowledge helps..
Btw just curious.. what are you?? How do you know this information not available in internet... So nice to see you man.
And regarding ur doubt, whether this happens in non pentile array amoled ...
NO.
I own a RGB amoled -Moto x ghost phone. It doesn't happen there.
I will check in moto x droid turbo . My cousin has it. So I will do and post results here.
And I wish to add this :
A 312 ppi RGB amoled (I have moto x ghost, 720p, 4.7 inch) is way better much much better than 440 ppi pentile amoled ( I have opx, full HD 5inch)
If I compare the images, they are much cleaner and sharper than opx . It's like the image has a depth, there is some stillness kind of feel. ...( I use colour control kcal, and so I test the displays in many settings not just default.
For example to make the images look similar as moto x ghost so that we can compare, I use rgb values as 32, 30, 27 value at 123, contrast at 121 and then slide the brightness slider to 3/4 or more.
Now both images look same in terms of how much dark areas are visible , the white wash noted in opx is now gone.
Now the images are ready for comparision.
Now the difference is the sharpness or clarity in rgb amoled. The feel difference i get is that there is depth in RGB. Its has a grip.
Hello RXT Users,
I bought a new Realme XT (6GB,64GB, Pearl White) Mobile, which works like a beast.
But within a week, I accidently noticed that the true deep blacks of Amoled display actually kills the surrounding Grey colour pixels especially in videos (or moving frames).
When I using Instagram, Samsung just posted some photos. when I try to swipe one photo horizontally, I noticed that the gradient colours (White to black) are like vanished some time and and a bluish shade is appearing btw the blacks and whites.
Then I started comparing this with other LCD panel, which is not doing these weird things. I also did a side by side comparison btw Realme XT and other LCD display by playing a dark horror movie. The results came was not expected.
First things first, the picture quality, colours, contrast and viewing angles are awesome in Amoled display, But the grey coloured details which are nearer to the black pixels are missing, they are completely gone.
Example:
• Original frame in the movie - A dark room with cupboards and interior.
• Picture shown in LCD display - white blushed dark room with cupboards and interior.
• Picture shown in Realme XT - A Deep Dark Black room with no interiors no cupboards or even no walls.
I can't understand why the Amoled display takes more time when pixels changes from black to grey colours, may it's because of low refresh rate.
Can anyone please tell the display refresh rate of Realme XT and try the above tests to clarify that I am not the only one who got these weird thing. Thanks in advance.
Note: I am using Amoled display for the first time.
This is quite disturbing to know. I was planning on buying XT and returning my Poco armoured, as it has ghost touch issues and I don't need that much processor power for daily usage.
Also, with XT getting started on development I hope I won't miss Poco. But with the above-mentioned issue, I'm getting skeptical because my primary reason to get XT was AMOLED display. I don't want to get disappointed by it.
Although it doesn't has ambient display and dark mode yet but I hope it'll be there in future updates.
Sent from my POCO F1 using XDA Labs
After reading this post I checked my xt's display for the greys in dark scenes with my le 2 LCD display and I'm pretty satisfied. I was able to see most of the details of dark scenes that was visible on the other phone. Plus I found it's very vibrant as compared to the le 2 and brightness level is also much better.

Thats how amoled works.. Not problem phone.. Amoled screens are like that..
Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Thanx in advance,
am
From what I have seen the AMOLED display on the SGTS7+ is actually pretty good for watching videos, the colors are excellent and so are the blacks.
It's an excellent display, as long as you use it over 30% brightness
As soon as you dive under 30%, it's a color-calibration sh**show, with a huge green tint issue (pretty much the same thing for any high-refresh rate displays of 2020. This issue was fixed by the following generation of displays, with the help of LTPO technonology)
I use it 5-6h per day as laptop replacement, and it's a blast during day time. But as soon as I want to watch movie at night time, the green tint forces me to push the brightness higher than my eyes wished.
The severity of the green tint will vary from one unit to another, but no one is spared.
