Can anyone explain this? - ONE Q&A, Help & Troubleshooting

Hi,
Just for fun I've put mu phone under UV light. I have some slightly yellow backlight bleeding and thought it might solve the yellow tint of backlight bleeding.
I don't have the yellow band, just some yellowish backlight bleeding.
And then I at once saw this:

Can anyone explain what's the rectangular part of the screen that is lighter than the rest of the screen? Or is it the glue that's everyone is talking about?
EDIT: my theory actually worked and no more yellowish backlight bleeding. It's still there (and only visible from a certain angle), but it's not yellow anymore. It's now white
I'm using franco kernel btw, so the screen tint is whiter than with standard kernel. This is when I noticed the yellowish backlight.

Is that the screen on with a black background? It looks so centered and rounded that I have a hard time believing it's not some sort of picture.
(I am not calling you a liar, just saying that it looks strange)
I could assume that your glue has been cured by UV but it has not spread across the whole screen yet. Maybe try putting it under the light again and check if that makes a difference?

The screen was off. Even worse: the phone was off....
That's exactly why I was surprised to see that. And why I asked here.
There is also nothing visible on the screen. The brightness is equal and no discolorations are visible. So I'm not worried about it. Was just curious.
I saw it the minute I've put it under UV light. Didn't change anything after 15 mins (except my yellowish backlight LED's became white) and in general the screen looked whiter)
On another forum I've read it could be some kind of oil to protect the LCD from the digitizer. Not sure it is but could actually be...
Could be glue but the shape is too strange for that.
Another guess is that they like sticked some kind of sticker on the glass (coming from manufaturer) and they remove the sticker without cleaning and then it leaves this kind of residu...
It's only visible under UV light, that's the interesting part.

[Q] Display filtering light under soft touch buttons...normal?

Hi to all again!
I just wanted to ask you a question about the display light: in a dark room, when you turn on the display and the soft touch buttons will turn on too, I notice a little bit of filtering light in the thin "junction" between the glass and the thin "glass border" of the display...only in correspondance with soft touch lights...
This can be noticed if you look at the phone "from above", I mean not in front of it, but if looked from top to bottom...I just can't take good photos, 'cause there's a very little filtering light...but here's a try, just to let you understand where's the right place, see the attached photo...
Is that normal?
Normal? No. It's a minor build defect. Will they do something? I doubt it. =/
Hmm...I don't know if I have to send it back for this...but I'M afraid that another one can have another problem...
I have a Grey version...
It's hard to compare with your picture, but I can see some light shining from the edges of my phone too. A thing which bothers me a bit more is that the light from the capacitive buttons shines trough on the screen, so it isn't completely black at the bottom

On my phone is only on a part of the thin line (the "connection" between the real display glass and the "border" glass) below the soft touch button...you can notice it only in dark rooms obviously, when the soft button light is on.
GLUE Strip
the display is glued to the glass as I read on engadget.com. I assume at this point there is no glue there. Fixing will make it worst. I would say live with it

Then yes I have the same, but I also see it on the top edge when viewing web pages or something white.

I think I'll go that way after all...I just don't want to imagine turn back to "the waiting game (from one to another)"...
A sort of bad luck has taken me perhaps...I've found a stuck pixel in the top middle part of the display...seen only with grey gradients or with some other colors, invisible with clear black and clear white colors...

Poor Screen Uniformity

Anyone else have any issues in regards to the screen?
I can look past the horrible refresh rate/ghosting, but this is really bugging me, amongst other things.
It seems the bottom half, mainly in the left corner, is quite a bit brighter than the top, making it seem more yellow, and the top a darkish pink hue.
The bottom corners also have very noticeable light bleed strip down the sides, which is noticeable on any screen/colour. It's like a small bright 3mm or so wide strip each side.
Half way up theres also a mark that separates where the brighter part of the screen starts/ends, so I'm wondering if someone dented the back of the panel when assembling it in the factory?
Either way I've requested a replacement, I'm just more curious to see if it's a common problem or not. Ghosting aside, the screen itself is quite stunning to look at, especially with a bit of ambient light in the room.

i didn't get your question, but if it is that i have any issues in regards to the screen? then no, i think it's stunning...
I also have the light bleed in the corners but it's only really noticeable on the bottom of the right bezel (in portrait). The light bleed looks like a strip on bright white light running up the right hand bezel before stopping about a third of the way up.
This is my second z3 and I'm contemplating whether to bother with another replacement or just return it altogether. Can't say I've been won over by the phone so far...I may just go for the note 4 instead...

Backlight bleeding

I got my Mi4C a few days ago and like it very much so far, but noticed some backlight bleeding.
It´s only visible on grey background (AdAway or Fire TV app) so i don´t know if my device is broken or not.
Adding a picture for example below but i have to say that in reality its less visible than on the picture.
Please look at the right and left edges.
How about your Mi4C?
Basically just want to know if its faulty and i should get a new one or maybe "Bad construction design" by xiaomi? Now i notice it almost everywhere btw
What exactly is the issue? You mean that the screen is bright at the edges? I think mine is a bit too but it's hard to notice. Can you provide more photos?
My backlight is visable at extreme angels so i think it is just the Sharp display used. It is not the highest quality of components.
I have some light bleed on the top, only visible with a status bar color other than black or white, so kind of a non issue for me
@Ydraulikos
Yes, thats exactly what i mean. The edges of the screen are brighter. Especially the edge marked yellow on the picture.
The other ones are only visible if you look hard for it.

Little round white spots on screen 2 replacements.

Hi guys,
I have replaced the screen in my nexus 5 twice now. I purchased the screens from Amazon. The first screen on white backgrounds I would kind of see a square image on the screen in white. It kind of looked like the outline of the battery. It also had a few white spots on the screen. I tried loosening some of the screws but it didn't help. I contacted the seller and he recommended another replacement. He sent out another screen plus digitizer and frame.
The new screen arrived and I put it in. This screen is a lit better. I know only get 3 tiny white spots about the size of the screws in the nexus 5. Two look like they are where the battery would be inside the phone. The third is about 3 quarters of the way up the screen in the middle and slightly to the left. Why does this keep happening? Anyone got any ideas on what could be causing this?
One thing I have noticed is in the dark with the screen on around the sides of the phone in places I can see slivers of light shining around the screen. It seams that the tape that the screen provider used was not sticky enough. Could this be what is causing the white spots? The screen seams firmly attached at the top and bottom just the sides. I heated it up with a blow dryer and held the screen down till it cooled. It slowly goes back to the way it was.
Thanks,
Rocky
Light bleeding from the edges of the frame in a dark environment is not uncommon with 3rd party screens. Putting on a case can help a lot.
As for the white spots, it may be a manufacturing defect that has nothing to do with the way you assembled the phone.
So there is nothing that can be done about the white spots? I don't understand how both screens did this. Seams like there is a very high failure rate. From comparison and matching numbers s to the stock digitizer the replacement seams to be a stock digitizer and frame. The white spots are annoying.
It's possible that both screens came from the same production run. I used screens from aliexpress and only one had a bit of light bleed around the frame. Once I put on a case, you could not see the light bleed.
None of the replacement screens had any dead or stuck pixels or hot spots.

Small light bleed on midnight black s8

I never even noticed this before but I read a thread about it and than I looked at my phone and there is a barely visible light bleed above the light sensor like if it's just light barely peeking thru the glass it's not on the display. It's where the top bezel above the front camera meets the frame. Is this something I should b concerned about. It's only noticeable in the dark. Is it it defected or is it normal.

I have it too with my s8+, there is a little dot on the left side of the device where the plastic connects with the screen.
It's a production variance - you could argue it shouldn't be like that, but you'll never get a perfect phone due to variances in the tolerances during manufacturing... Mine has it too along the side (as did my silver S7 Edge before it).

Depends on if its just light from mossing paint or an air gap.
The front glass is glass so its see through, and then there is a black flim/coating put on it. Then it is glue to the frame of the phone.
So if a piece of the black coating got messed up then your get light showing.
Now if its not glue down all the way and there is a gap then the water proof is gone.
There was a guy on xda that got his coarl blue s7e and one corner was missing some of the blue coating.
I have this light bleed over the iris scanner and the front camera. Then I searched where it comes from. I saw if I had a white screen (for example settings) and a high brightness a big light bleed in the front camera if you look from the top of the phone to the bottom of the camera. There I see light from the screen. It's not a problem for me, but have you guys this too? The question about water resistant is interesting in this case.
hope it's jus paint that is missing. That's fine with me. If it's not glued down right I'm gonna have to go exchange it. I'm gonna have to check it out more and see what it is.
I'm seeing something similar with my unit...but I think this is more of a light reflection off the interior of the case because of the space/void created by the two sensors in that area. I say that because the reflection occurs directly about the sensors and it moves around a bit as you change viewing angle. Am I crazy?
It is a reflection that gets passed on to the IR LED. Not a sensor.
Harmless, and seems to be on all units I looked at.

How bad is your bleed? I JUST noticed today that mine has bleeding on the right edge? But it seems to go all the way down the side? Mostly visible when there is something bright on the screen? There is also a little on the bottom left side of the screen..
So, can we say that the light bleed above the front camera is normal then? I have it too.
