Hi all, I have a Galaxy S21 + and saw two circles in the screen visible in direct sunlight, located vertically in the top right (the sun must be very strong, for example at noon or in summer). In addition, I also see a spot where the fingerprint reader is (but I think this is normal).
Do you also see two circles in the upper right, vertically, in direct sunlight?
I insert a photo of a xiaomi taken from the internet, for the moment I can not take a photo of my phone. The defect is as in the picture, but the two circles are in a vertical position (and not horizontal).
Meh... keep it out of direct sunlight if you value your display!
If not visible at any brightness in a normally lite room, it's ok I would think.
Use Screen Test to test it.

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...
Hi XDA, I have a few questions about the camera sensor problem on my Galaxy Mini 2.
Yeah, I know it's a low-end phone with a weak camera (and it would seem that I'm making a big deal out of this), but I'm not asking this because I'm annoyed by it - I just wish to know if it's a completely dead pixel, and if such thing as "half dead" pixel exists. Such things can happen on high-end devices too.
So, what's this all about? There's a very small dark dot on my photos, especially photos of the sky and other uniformly lit objects. It's most visible on lower ISO values - although you can't manually set ISO on this phone, the value shows up in IrfanView's info box.
The problem is, I don't know if it's a completely dead pixel. You see, the dark dot and its surrounding area never read HTML color #000000 (full black) in any photo viewer on my PC. So could it be a "half dead" pixel, if such thing exists (a pixel that's not dead but simply can't sense light correctly)? No, it's not a dirty lens or dust, I checked.
If I take some indoor photos (higher ISO values, more light to camera sensor) the dark dot becomes brighter, more like light-gray. And on completely exposured (extremely bright) photos, the dark dot is almost gone. Another thing, indoor photos on Mini 2 are usually blurrier (lack of autofocus), and the dark dot on them is also blurred - it's not sharp independent of its surroundings, which would indicate a damaged camera sensor.
Finally, do such dead (or half dead) pixels have a tendency of growing in size (expanding) over time? If not, I can live with it.
Nowadays, OLED screens are dominating cellphones, which have a critical potential problem as screen burn-in if you watch videos long time and high brightness with fixed picture parts such as TV program's banners, logos, letterbox black bars, etc. To prevent burn-in, I usually crop the video picture to make it full screen on my cellphone to make sure no any letterbox black bars appear, then I video pan the picture up or down to move the banner or logo out of the phone screen. Usually I don't need to zoom in as an extra step to sacrifice any more picture(meaning crop more picture) in order to move all static part of the picture out of the screen. Just crop to full screen and a simple pan is enough and it'll work like a breeze. Such is what I do with nPlayer Pro. While MX Player Pro does not allow this as it seems to me. Cos it doesn't limit the boundaries while I pan the video up and down. It's simply a random move like out of control that actually always results in worse scenario for preventing burn-in. Cos you easily move the whole picture's edge into the screen in any one direction. This creates more burn-in cause instead of solution. You just cannot do it perfectly to make sure at least 2 sides of the picture edges are aligned with the screen while you only move in the other 2 directions meanwhile never have any picture edge inside the screen.
For example, watching a Bloomberg TV video(16:9) with a Samsung Note10+(19:9), I need (1) to crop to make it full screen, then (2) to move the picture down to hide the always shown banner from showing on screen. While doing step (2) with MX Player Pro, it's not humanly possible not to move the picture in either left or right direction, thus it always creates an extra black bar either on the left or right. And yet I don't want to zoom in to solve this as I don't want to unnecessarily sacrifice any more portion of picture. I want keep as much picture as possible on my screen. The other thing is while moving the picture down in this case, you easily move too much picture out of the screen and create an unwanted black bar on the top of the screen, while I just need the top edge of the picture aligned with the screen top. If there are limits for edge alignments, each move will be so easy and Video Pan will function like a charm. Otherwise this function just feels half baked and not practical. Seems to me that there's no point to move any picture edge within/into the screen when it's not in. All picture edges need to be either aligned with the screen edge or outside of the screen edge when you pan a video in crop & full screen mode. Never inside.
So, please add move limits to all 4 directions for Video Pan. This will make MX Player Pro perfect. Thank you so much!
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.
Is anyone having issues with the resolution in some apps?
I've noticed that in some games and apps I use, it seems like the image is bigger than what's displayed on the screen. Like the sides may be cut off a little or the corners might be hidden. It particularly shows to in Star Trek Timelines when the X in the upper right corner is mostly obscured.
Is there any way to adjust the on screen resolution so it fits the screen better?
Thanks!
