Screen defect - Glass or digitizer? - Samsung Galaxy S8+ Questions & Answers

I noticed a defect while out in the sun today. In the sunlight I can see a crease/distortion effect in or under the glass in the bottom half of my screen. Maybe a third of an inch long. It's only visible to me in the sunlight or bright light. It's not on the outside of the glass though because I can't see it or feel it. Just wondering if anyone else has noticed it on their phone.

[Q] Are these dead pixels?

Hello guys, i just noticed today this hairline tiny black strip on my display, thought it was dust but it didn't wipe off. My phone is a week old and i never really had a device with defective pixels before so i can't really tell what this is. I ran the defective pixels fix videos for 30 minutes but that didn't help. Sorry for the image quality, i don't have a decent camera to capture those tiny pixels.
I also noticed that i have light bleeding from all edges when i view the device from an angle, is that normal for the nexus 5?
Could it be that there are gaps between the glass and the display that allow dust to go beneath the glass, and this is just a dust particle under the glass?

The light bleeding is normal I've seen on all Nexus 5 i have owned, the "Dead Pixel" is a little hard to judge , but in my opinion as its not solid square(s) i think it may be dust or debris.
I had purple spots start showing up on my first one. That doesn't look too bad but it would bug me too.
Do you think that more dust could get in if that's the case? I have a local warranty and i'm leaving this country after a month, if the issue won't grow bigger than this, then i may just live with it as i don't think LG would give me a replacement unit here.
Not sure if it would be an issue for them as the phone isn't dust proof,I'm no way saying its cool as it would annoy some people. I guess best thing is contract them and see what they say mate

It looks like dust to me, but to know it for sure I recomend you to take it to a LG Center.
They may not give you a replacement unit, but at least you will know what the problem is.

[Q] Grainy screen?

Does anybody else have a rather noticable grainy screen? It looks like a layer between the diodes and the front glass. Its as if I was looking on the screen with some photoshop grainy effect. Or better, if you put a very thin paper in between the diodes and the front glass. It gets significanty better with brightness turned up to max. But it doesnt go away completely. Its most pronounced with darker colours. Black is fine though, no mura effect there.
Its really annoying to look at. Is it normal? I thought LG supposedly fixed this issue which was very common on the original Flex.
I only saw a grainy screen when I turned the brightness way way down below the normal with Lux brightness control.

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.

Glue recommendations?

The first time I dropped my Mi Mix I had replaced the screen from vopmart; however, I wasn't happy with the quality of it. I received a screen with frame and it had bad light deformities (light bleed on edges, inconsistent lighting on the screen itself, scratch on middle of screen) and the frame glued to the screen was uneven.
Well... I dropped my phone again and I get to put another screen on it. This time, I bought the screen from eBay with a coupon. The screen ended up costing me around $30 USD. Not bad! The screen came in and I tested it and it's perfect (no dead pixels, no deformities, consistent lighting). Only problem is the frame is not attached to the display. I have spare frames that I can glue to my new lcd; however, not sure which glue is best to use. E6000, B7000, or T7000? I was thinking of using T7000 since it's black and would help prevent light bleeding. I'm open to suggestions.
What glue do you guys recommend?
