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

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...
So I use skype on my desktop to video chat with my girlfriend who is a few states away, we do this every night. I used my surface instead of my desktop sometimes but I stopped, I got paranoid that it's damaging the screen somehow even though the video is usually all black. So my question is, is it really doing any damage by having it on all night (brightness at lowest)?
Having a display on for a longer period of time will indeed cause image retention. This can be temporary or permanent depending on: how long, temperature of the device, content of the screen...
In any case: no, it's not good to leave it on for the entire night.
Not only can it cause permanent damage, the brightness of your screen will also wear off faster.
AMOLED screens are less affected but even there it can happen over time.
If you really want to do this and you don't care about the lifetime of your tablet, make sure the screen is entirely black. Full screen video without any buttons, interface lines, icons... (it's those things that will be visible after burn-in on the screen)
Hello guys
I've ordered my Nex and cannot wait to get my hands on it (Hurry up gearbest!).
One thing bothers me:
On a youtube video I saw recently the reviewer mentioned that the display of the nex is super amoled. He then explained concerns that if the fingerprint logo - to show the position of the in display finger print reader - is always visible on the display this could result in a burn in on the Nex display.
What are your thoughts about this?
Thanks and BR
It's not always visible, only when you need it or when you shake your phone.
"to avoid burn-in is to ensure that your display doesn’t show the same thing in the same place for LONG periods."
So does the Nex have a pocket mode which prevents a wake up? - I mean this thing gets moved a lot in the pocket.
I would say yes but im not sure where ...
In constant movement the scanner is off.
This phone has a sensor that detects when the phone is near your face and shuts the display off when your on a call. This same sensor knows when your phone is in your pocket and prevents the fingerprint from turning on when in your pocket.
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!
MY S22 ULTRA, 5 months old, began 48 hours ago to show the background of the lock screen (active display with a black background, in a very oscillating dark green color.
It only happens when the active display is activated, and sometimes inside with a dark background when it tries to adapt the brightness to the environment, it occurs as a kind of almost imperceptible flickering.
Internally the navigation, videos, photos and others are all perfect.
Things I have already tried:
Wipe Cache
Toggle between all screen resolutions and display options etc etc
With the mobile turned off while charging, if I press the power button to see the percentage of charge, that green is also seen.
I was reading that it may be a screen failure, but I still refuse to leave the phone in repair (150GB of internal information already copied), I don't know whether to wait for an update or what else to try.
Any suggestion?
Sorry for my english
I don't have answers for your issue, but I had exactly the same issue. I damaged my screen and it started appearing right after the damage to the screen. I don't use AOD, but mine did the same thing when it was put on charge.... no black screen, just the weird green. I turned off adaptive display and it disappeared. Had 2 updates since then and put back adaptive display and now the green is still gone. Not sure if was an update or the adaptive display change that fixed the issue

No, only official android updates, last 1º august
I had that problem in my note 8, had to send it to warranty to replace the display circuit and the display because of burn in pixels.

Can it get worse or will it always stay like this?
I just replaced the screen protector and it's still the same sometimes, not always, it seems to improve things but it only appears if I force the situation with dark environments.
How do you explain if it was a screen problem, within the android there is no display problem in photos, videos etc etc
It only affects the active display and while the adaptive display is active, that's why I don't want to send it to warranty so soon, I even hope that with Android 13 it will be solved!
To those who had to change the screen, did it come under warranty and the fault has been recognized without having to pay anything?
Obviously, if it were the screen, it would have to be some sensor or sector of the screen that only acts under certain conditions and I don't know at the hardware level what it could be, if any sensor or sector of the screen is internally damaged, it is very strange.
Thanks for answering.

It was everything free, they replace the display circuit controler, the display and battery (mandatory on note 8 if you replace the display they replace also the battery).
The problem was stable, no true black, allways greenish, sometimes flick and turned true black for couple of seconds and returned to that greenish black. Was horrible, my luck was i had 24 months of warrany and this happend on my 22th month!
Hi, I have same problem for 2 weeks now. Seems to occur when in low light placed and adaptive brightness is on. Did you find solution?
