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...
Hi all
I've had my tf300 for a few days now, and I have a different kind of screen brightness problem. When watching movies or looking at pictures, they often look like they've been recorded/taken with very strong lighting like very strong sunlight. The effect isn't influenced by the brightness settings on the tablet, high or low the effect is still visible. The first tf300 I had did the same thing, so I returned it, figuring it was a problem with that particular tablet, but the second one does the same thing.
I've "solved" the issue by downloading screen adjuster from marketplace and setting the brightness setting in that app to 70% or less. Apparently that app adjusts a different screen brightness than the one the built in one does, because by using that screen brightness adjustment the effect disappears.
Anyway I was wondering how widespread this issue is - if it might be an actual defect or ASUS just screwing up the brightness settings of the screen.
Regards
Hello guys,
I have a problem to display of my Nexus 5 and would like to make sure that others are not. I checked other Nexus and saw that some have this problem.
The problem occurs when we have a kernel that supports the backlight dimmer as the Franco.Kernel or the Elementalx Kernel. If enabled through the app franco.kernel updater Kernel Setting, putting the display at minimum brightness and white backgrounds I notice a dark spot in the lower left corner of the display. Obviously if I raise the brightness of this stain disappears. I am attaching some to better understand the problem. Also check you. Thank You
Hi,
The touchscreen is getting unresponsive and unusable when the brightness has been set to high for some minutes. The problem disappears when the brightness is lowered. Also turning off the screen for a moment helps but the problem returns when it is turned on again. Propably, the heat generated by the backlight seems to affect the capasitive touchscreen calibration negatively. Obviously, it is a no go to rely on the adaptive brightness as the problem is showing when being outside in bright light.
A video demonstation is available on youtube with the name " ZTE Blade S6 problem - Touchscreen turns unresponsive when brightness is high!! " (youtube tag: y7oqd89X5jY) - sorry, I am not allowed to link outside XDA. The unresponsiveness shows up at about 10:00 minutes inside the video.
- Can this problem be solved and how?
- Is this problem stand alone or general?
Thank you and regards.
Hello everyone,
I noticed that after updating my Mate 8 to Android 7, my screen seems to have an Auto brightness functionality going on, even though I've turned auto-brightness off.
For example, when my screen is in direct sunlight, I notice that my apps are brighter, and when I cover my light sensor they become darker even though my brightness is set to max all the time.
Anyone know why this happens?

There is an option in developer options
Please check the screenshot.
Increase visibility under sunlight
Check if this option is turned on. If it is on then switch it off and see if your problem is resolved. :good:

Hey, thanks! I didn't know that option was there.
I've turned it off now, and I'll see if this fixes my issue.
