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.

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...
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?
Recently my screen has started developing strange shadows of apps that i use for longer time, like browsers, keyboard etc.
Even youtube after using for more than an hour or so give shadows on screen.
The issue is more persistent with the keyboard, as i am a heavy internet user (7-8 hrs online) and most of the time keyboard stays on the screen, the screen is showing me a persistent shadow of keyboard, initially just after using it for more than an hour the shadow is very clear and it stays even in the brightest apps and screens , later after sometime it starts to fade but never really goes away, its there always faintly.
What should I do?
Attached screenshots but i don't know if you guys can see them or not.
Edit : its on the screen (hardware)as screenshots don't have shadows, don't know if my screen is faulty
Screenshots are no good, take a picture of the physical phone screen instead.
Screen Burn-in Tool could help, it's designed for AMOLED, but it might end up having the same effect, and there should be no risk (except maybe some wasted time ).

Thanks but i think its better to get the screen replaced because the burn-in tool is a temporary solution, it again comes up after few hours and usually goes away in the morning as i don't use phone at night..
Also screen flickering is visible on very close inspection of some dark screens and checkered wallpapers
Hey there, I recently bought the OP8. Sadly, my display have an issue.
Get a dark grey image. I used a dark grey image from google image search.
Set brightness at 20-30%, auto brightness off, DC dimming off, screen calibration to natural.
Display the dark grey image, make sure it cover fullscreen.
The issue is, which can be seen more easily inside a dark room:
The under-screen fingerprint sensor is visible as 2 overlapping rectangles
Photo attached ..
Please someone confirm me that is normal or not. Can i continue using the phone? Everything else is great. Just this issue. Should i keep the phone? I Got it from online unofficial , so It's gonna be difficult to claim warranty. Thank you
This is normal. All fingerprint readers for all phones that sits under the display are visible if you just find the extreme colour setting, light setting, angle, sun light or whatever far-fetched, never used setting needed.

This is normal, the rectangular portion will be translicent so that the reader behind the screen can register your finger print. for the reader to see your screen it needs that window.
Congratulations you have a FingerPrint reader.
Hi, I am on latest 11.0.1.1 global. I actually don't remember that I had these issues on v10.x, but definitely since v11. I use 120Hz, FHD+ with all color optimizations turned off and with standard OP launcher.
I experience some flickering of the whole display or just parts of it in many situations. It starts to get annoying.
Examples:
1) open the hidden app menu. Right before it opens the whole(!) display flickers white once. Good visible since the top bar next to the camera hole flickers once.
2) Go here and try to type in any number. The moment the GBoard comes up at the open, it flickers just the bottom part.
3) Lock your phone. When you fire it up and the Lockscreen gets unlocked, if flickers once.
There are so many more situations but the depend on some apps.
Is this normal behavior? How to fix this, if it is not?
