Hello friends,
Recently I came across this article regarding burn-in issues in AMOLED and according to the article it seems that screen filter apps can cause irreversible damage (burn-in) on AMOLED. I'm quoting few lines form the articles below,
Some screen filters can turn the screen to another color — for example the app Twilight can make all images red-hued. However, this was reported to intensify screen burn-in. While red-shifted colors will decay less rapidly than blue or green, overusing any particular hue will eventually create a noticeable impact on the color accuracy of your screen.

Personally I use red filter at 15-35% varyingly.
My question, How fast could the burn-in occur since I use Twilight every night?

I have an A511. Yesterday I used it outside. Thereby I have recognized strange color effects. When I tilt it (by >50°) the reflected light look like a rainbow. The pattern changes by tilting and rotating my tablet. Is that normal or a defect? Acer support claims that it it normal and caused form some kind of organic glue. Can that be?
Kind regards
Loerkus
same on A700
i took a picture, seems to be the same effect on my A700...
Just got an answer from Acer to this effect: this is normal if you touch the panel with force, you see the layer between the panel and the touchscreen.

Very interesting. Can you repost your picture please (dead link). I have attached a picture of the interefence pattern of my tablet for crosscheck reason. See here http://db.tt/9yMC5p0V

I do not touch it for seeing the color pattern. If this is true than my display shows strong tensions.
polarization
I see what you mean, i think this is caused for the same reason. As i think about it, i got the idea that this is only caused by the refraction of the light. The emitted light of your monitor is polarized, and refracts in addition on your panel of the acer. it is in fact a simple physical effect. If you use polarized glasses or a polarizationing filter from a digital camera, you may see an similar effect, if you spin the glass by 90 degrees. Preesing on the panel leads to a minimal bend and mirrored light refracts into its basic colors. Lools like oil on the panel. What i see in your picture is the polarized filtering of the monitors light. It leads in the refraction to lighrs basic colors...
Same cause, similar effect but quiet normal, i think.

I agree with your explanation but it is also visible when I look at the reflected sky. Ok, in that case it is not so strong but I want to be sure that the display is OK. I have only 2 days left sending it back (and lock + unroot it)
don't worry
from my point of view the effect only occurs by reflected light and not from the display by itself. If your display is ok, you won't see this color disturbances by normal looking (without any mirrored light) - so you may keep it. I can't verify it on my A700 under clear sky conditions in this intensity, i think it depends on the panel resolution and the attached filters within the panels.
By the way, i'm not sure, if there is a (hidden) flag in the Acer Android system to check if the device had been unlocked before. Motorola (for example) added a constant/variable to the system. After relocking and unrooting the device still sends after "fastboot getvar INFOiswarrantyvoid" = yes. There was no known way to change this constant. Neither by reflashing stock firmware nor by setting this explicit value...
I have read articles that said using DC brightness on OLED/AMOLED screens can effect colors, particularly at low brightness. How are people finding it? I dont really care if it makes colours "less accurate" as long as they dont look weird
Looks fine to me. Barely can tell the difference.
Working well as described, couldn't tell the difference.
Can someone try to port it to OnePlus 3 / 3t?..

What makes you think the 3 / 3T screen is capable of DC dimming? Can every AMOLED screen support it?
First off, I don't notice any flickering when the screen brightness is low so maybe DC dimming isn't for me. I'm sure someone with a fancy color monitor device will probably post a technical breakdown of how it affects the screen, but I don't see any difference except in one scenario.
In bed I tend to set the brightness settings on the lowest and then turn on nightmode to dim the screen even further. If you have small white text with a black background such as the settings menu or Youtube in dark mode, some of the text fades into the blackness and is unreadable. Images with dark colors or areas will look weird because you won't be able to distinguish them apart.
I tried to take pictures to show a comparison, but the screen is so dim that it doesn't work.
Hello to everyone, new user of the Xperia 5ii and I have two problems
1)Has anyone observed a slightly change in the colour of the screen between 60 and 120hz? It's very obvious if you have dark mode and sit in a dark room. When you toggle the selection on and off, you can easily see it
2)I was trying to upload an Instagram story and the quality drops significantly. You literally can distinguish pixels. It's only on Instagram, on Facebook there was no problem. Also I tried to upload the photos from another device, and the same problem exists.
Any help is most welcome

This is true and if being honest, quite expected. It most noticable when the screen brightness is somewhere 5-20%. You can clearly see it when toggling the 60 or 120hz. The panel itself is great, many oled defects are gone or very minimal. This green tint issue is quite common on other 120hz panels too (mostly Samsung made). That might also be one reason why the new Iphone 12 phones don't have 120hz, too much quality problems.
So yes, there is a green tint. But luckily it is very minor and only on certain screen brightness. Haven't noticed it when actually using the phone.
Not sure if this count as a defect to get a replacement (the replacement would probably have the same issue).
Attached few photos I took.
I have the same issue in low-brightness and 120Hz activated
Have you noticed changes on your smartphone screen? Suddenly you were using the device and noticed a certain shadow in the image, or even remnants of images that should have been displayed at that moment? If so, know that your phone may be suffering from the burn-in effect (Ghost Screen).
WHAT IS THE BURN-IN EFFECT?
Burn-in effect (or phantom screen) is the name given to a permanent discoloration of part of the smartphone screen, caused by the irregular use of pixels. Prolonged use of still images can create a permanent shadow or ghost of that image on the display.

Welcome to XDA
Will try it for sure.
Enjoy the forums!
Hi guys this is my first post, and I was wondering where I could get an answer for this...
So the thing is im an Uber driver, this means that I have my screen on almost all the time while driving (avg 5-6 hrs) and I'm planning on upgrading my phone and not be límited to lcd panels so... I was curious that I could Run an app called Tasker and make a script so when I open the Uber Driver app and at certain intervals the colors of the screen would be inverted (I think this is for visualy impaired people) so that the pixels that were white now are black and blue are yellow etc But I am not sure if this would prevent burn in bc after all the screen would be ON a lot through the day... Thanks for reading!
LCDs don't "burn in". The crystals become staticly polarized. It's reversible.
