Recently I switched to Evolution X custom rom on my Galaxy A205F. It works amazing, there are no problems with optimisations.
But the text and some things are too bright. I play Battle Royale games and the health bar got burnt into the screen.
Is there any fix for this like OneUi had? So that this doesn't happen at other parts of the screen.
Keep brightness at 50% or less.
Avoid using in direct sunlight*.
OLEDs have a limited lifespan.
Less brightness/time on means a longer lifespan.
Blues OLEDs have the shortest lifespans while the lower wavelength energy reds the longest. Any type of blue LED or OLED have notorious shorter lifespans than their lower light energy red counterparts.
However to generate the color white the blue pixels operate at a higher output in comparison to other colors.
So white produces the most overall damage as well the most damage to the blue pixels.
Limit the length of time the same static image is present especially whites and blues.
Use dark mode and darker wallpapers, minimalist icons packs with more red and less whites/blues.
Get rid of perpetually displayed icons on the header bar; use a pull down style if possible.
Rotate the position of widgets and icons occasionally if possible.
*it's not just the OLED semiconductors in the display but thousands of semiconductor that drive them. All can be damaged by excessive temperatures and their heat sinking capacity is limited. A display operating at full brightness in direct sunlight on a hot running device can damage a display.

I'm fed up with the flashy effects and background picture/pattern nonsense of the WM5 default blue theme. I'm looking for something minimalist, that doesn't hog as much resources. Any ideas where to look for something like that?
Most downloadable themes I've seen have colorful backgrounds and shaded menubars etc. I don't need that crap. All I need is a black background, thin, single-coloured menubars and windowframes, no animations, you get the idea.
i have a Palm Vx i can sell you cheap
No, no, you don't understand. I like the technical features of the Universal. I love having the great screen for watching movies or browsing the web with Opera, or the Wi-Fi or the 3G for on-the move connectivity. It's all good. But it makes my heart cry to see all this potential crippled by the resource hogging OS that's running on it.
i understood what you meant, this was a joke.
i love this device as well, for precisely the reasons you mention, but to tell the truth i don't believe a "light-weight" skin would improve performance all that much, if at all.
it certainly is sluggish, and i wish it ran faster, but even so it's better than carrying a phone, an ipod and a camera around in my bag...
I think that acctually we should have white background to save more power. Black colour on TFT screens is created by put max power to pixels. White colour dotn consume more power that is needed to light a fluorescent tube in the display which is turn on anyway. just my 0.02$

Are you sure about that? Isn't a white pixel getting max. power?
I am sure. In LCD screens, when turn on (not in some king of power saving mode) fluorescent lamp is always glowing so to get shades and dark colour You ll actually have to "cover" light with LCD pixel. For LCD crystals to block the light they must be applied with maximum power. So if You have whole white screen theres no crystall blocking light and screen consumes energy only to light fluorescent lamp. If You have dark picture lcd display have to draw more energy not only to light fluorescent lamp but also to max out energy to all pixels to block the light.
Here is the classic black today skin that I use. Its only 2kb and is extremely minimalist. Hope this helps!
@nabuhonodozor
The exact inverse of what you said is correct.
Basically, in order to achieve the WHITE colour the Red, Green and Blue elements need to be lit consequently needing MORE power than would be required to achieve the Black colour which wouldn't require any colour elements to be lit.
Hope this helps.
Q.
After a year of usage, through using the antutu test app for LCD I noticed that the pixels on top edge of the screen are brighter than the rest. It's probably because of the black notification bar.
Can other users with super amoled NS check this and see how their panel holded up? The best way to check it is with a plain gray or blue image.
Thanks

I've the i9023 myself, but current (possibly future, too) OLED panels degrade unevenly. Whites and blues use the most power and lower the brightness after prolonged use more so than reds and blacks (with blacks effectively turning off the pixels and draining little to no power and don't effect brightness).
These kinds of effects are likely going to be more prevalent now that some years have passed since the first OLED displays have appeared. For comparison, LCDs use a backlight behind the screen which uses the same amount of power between white and black, though blacks look a little grey. As a result, there is even brightness fade.
Hello.
I just bought Galaxy S8. I know that AMOLED screen really turn off pixels when the colour is black. So, is it true that using black theme can prevent burn-in on AMOLED display?
Why Samsung remove black navbar colour in one of update? I just read that it's possibly connected to burn-in display problem.
OLED screens don’t use powered pixels to create the black color on a display; instead, black pixels are simply pixels that are switched off. This means that activated pixels — that is, the non-black pixels on a display — degrade at a faster rate.
In extreme cases, this can lead to certain parts of the screen becoming lighter than the rest of the display — what we typically refer to as burn-in.

So, is it safe to use black theme on Galaxy S8? Will it help to avoid or slow down screen burn-in?
I think you're reading that wrong. The quote is saying the NON-black pixels can lead to burn in - they are the ones that degrade faster.
I run my phone as black as I can get to conserve battery. Plus it's easier on the eyes.
Not sure if it's visible but I'm fairly certain that I can spot this. Check the attached gif. Notice how the lower three thumbnails lag while scrolling . This thing is slowly making me insane.
Any suggestions? Phone is pure stock, no modifications, miui 11 global 11.0.1.
yes, i can also spot wavy motion when using Instagram in dark mode with brightness low.
the edges of images give some black wavy shades on scrolling same occurs when we use in direct sunlight color are too sharp on full brightness under the sun
I think you speak about the big AMOLED weakness, that's "normal" and can't be fixed...
It's normal for AMOLED displays and VA Lcd displays.
when its complete black pixels turn off and it takes a while for them to turn on again and show the new color
less visible in higher brighnesses
Yeah i have this problem any solution to fix?
Its very simple. Because we have an OLED display the individual pixels can and will turn off to display a true black. But when that black pixel that was turned off needs to change color to for example green, the pixel will have to turn back on again. And this takes a few miliseconds (probably more than 15ms, but thats just my opinion) thats why you see ghosting/trail. We cant do anything about this. Better have true blacks then less ghosting and greyish blacks on other panels like LCD.
Hey, I've recently noticed small dark dots on my screen. Few of them are in a left corner, but these are only visible in a really dark room, on a really dark grey screen and on the lowest possible brightness. However, there is one dot in a center part of the screen which is more visible than the other ones (it is still visible at approx. 50% (or even higher) brightness on a dark grey screen). This one particular dot is newer than the corner ones. I couldn't find a lot of information about this issue, but from what I've found I learned that this is a common issue with some AMOLED displays. Is it true?

Sounds to me a lot like dead pixels
My Mi 9T also has this. It's not dead pixels, but rather unbalanced pixels due to manufacturing tolerances on (AM)OLED panels. On lower brightness some pixels may be sligthly dimmer/brighter than others as it is difficult to drive an OLED panel evenly on low power. This is also why the screen can seem to flicker on low brightness, because PWM is used the pixels rapidly turn on/off to keep image quality acceptable on low brightness. Without it the artifacts would be even more visible.
Every OLED screen will have this to some degree, but it is more noticeable on non-flagship phones because they tend to get the panels which are not good enough for flagship priced phones.
