I bought an HTC Evo 4G LTE on Friday along with a screen protector and a case. Anyway, I'm no good at putting on the screen protectors, so I asked the phone guy at best buy to put it on. Fast forward to this evening and I noticed what appeared to be 3 small specks of dust that got under the protector, with a larger one. As I was inspecting them, I found that they were actually tiny black circles (think speck of dust size or even dead pixel size). I'm going to be taking the phone back tomorrow for a replacement, but in the meantime, I'm curious what these are? I've done a lot of googling and the closest two pieces of information I've been able to find say they are either dead pixels because they are about the right size and show up best against a white background, or that they are moisture damage.
The question is, which seems most likely? Can dead pixels manifest themselves as circles rather than squares? And also could moisture damage be so minimal that only four little spots appeared? I should point out that the screen protector was the variety that uses a liquid sprayed on the phone to ensure a good clean overlay on the screen, and also that the salesperson used some blasts of compressed air directly on the screen to try and clean it before applying the protector (I've heard thats a big no-no).
I had a similar problem once with a no name chinese tab.
I noticed a bunch of black spots (square) the size of dead pixels all over the screen. I removed the protector and wiped the screen clean. It was tiny specks of dust indeed.
While blowing hot air onto the screen is a big NO-NO, IMO blowing compressed air wouldn't cause damage. Its the heat that damages the LCDs.
Curious how specks of dust would produce that effect, considering they are not uniformly shaped. Anyway, I've got my fingers crossed now that the problem really is dust rather than a bad screen, since I would hate to start this new phone off the same way I started my last one (returned for defective hardware / software 3 times in 3 months).
Thanks for the input and I'll be sure to post up the results tomorrow when I take the phone into the store. I've already discussed it with the store and since the salesperson was the one who installed the protector, if it turns out to be dust, they will replace the $25 protector free.
Turns out it was dust, or some other contamination, but it was UNDER the screen so that, while you could see them with the phone turned off, you couldn't get at them in any way. Home now with a replacement phone, but as my first experience with HTC, I'm not super impressed...

picked up 2 Nexus S on release day, went home happy. Preoccupied with work, so I only powered them up last night.
To my Surprise, both phones have dust under the glass! WTF Samsung? Removed the plastic sheet on the front to make sure, and yes, it's under the glass.
on one phone the dust was smack in the middle, while on the other phone it was a little left of the middle.
Can't be seen on a dark screen, but once you switch to a white background like the web or texting you can see it.
I know I am probably being OCD and anal about this, but heck I paid over $1k for both phones out of contract.
Went back to BestBuy and returned them promply, of course now they are sold out, and I have to wait for the next shipment.
Just wondering if others have similar experiences? BTW, I also had a Galaxy Tab and before returned it, it also had some dust specs under the glass...
I also own an HD2 and G2, seems HTC is better at QC.
Shame, really want this phone but WTF samsung?
Nope you sure its under the glass?

No dust under the screen here.
It seems that this first batch of phones is a rather mixed bag; some have defects and others are fine. It was a good idea to return them, hopefully your replacements will be free of issues.
My first S had a little speck of something. I initially thought it was a dead pixel, but I could see it when the screen was off also so I assumed it was dust. I returned it and checked the next one out before I left the store and it seems to be good.

100% sure, remove the screen protectors on both of them and rubbed the area where it was, thought it was a dead pixel too, but no it was fine on a dark background, but on a white background could see it easily.
sold out at my local bb, but still available online might go that route.
just wanted to see other people's experiences or maybe they didnt notice yet, lol.

this happen when you have 2 layers for the screen. the internal part and the upper part where you touch.
there is an advantage for this. if god forbid you dropped and broke the screen, only the upper part gets replaced. and wouldnt cost you much to do so " and you wont get another screen with dead pixel and being OCD whatever the new screen is good or not. because the actuall inner screen isnt touched.
the bad thing about is what you said. dust can enter in the middle between both layers of the screen.
even if you get a new nexus S without dust under the screen, if you leave it in the open area with sun and wind always hitting it, you will get a dust somehow inside as well. so make sure your phone is in a pocket most of the time.
the only phone i remember right now that had both layers of the screens touched as 1 part is the iphone 2G and the iphone 4 " i am sure there are others but i dont know "
this result to no dust under the screen no matter what " unless the dust came from factory while they were attaching both screens on top of each other and glue them "
but if you break your screen in the iphone 4.... god help you.
Yeah, after about a week and couple of days of usage, I've got my first spec of dust in the top left area of the screen. Really, it's nothing noticeable but I do have some sort of OCD with my phone (god help me if I get a visible scratch on the screen).
I don't think it's really worth taking it back to get it changed as this Nexus S I have currently has no problems whatsoever, I don't even have the pink or yellow screen issue with this one. I think I'm just gonna have to live with that one spec of dust for now...
I think this may be just bad QC. I looked at ifixit taking apart the NS. Basically they said the trickiest part to the disassembly was the screen, and they had to use a heat gun to soften the glue just to separate the 2 screens. So dust entering between those 2 screens would be pretty difficult unless the glue wasn't properly applied from the assembly line.

I don't have dust under my Nexus S screen... but I do have dust under my front facing camera! And its only recently just got there - I remember playing around with it extensively when I first got it 6 months ago and the camera was really clear and sharp.
Now it is all fuzzy and white haze. And I can see all the dust particles on the underside of the glass. Annoying!
Anyone know if there's an easy way to clean it? Or is it a case of back to Samsung?
So I just took out my sensation from the box and noticed the stock screen protector was off set and already peeling back a great amount on the top corner. I looked closely and noticed that the small tab at the top of the screen protector is actually inside the ridge of the phone, in that small thin crack where the front-screen ends. That was what cause the screen protector to not lay flat and started bending inward. I slowly peeled the protector back and when it came to the part that was "stuck" or jammed into the crack it took a good tug (I guess it was the adhesive...or it was really in there) for it to pop out. This couldn't have done any damage right? The small crack leads to nothing does it?
Probably just means it got caught in the gap when being fitted. I assume when you say 'crack' you mean the gap where the screen meets the rest of the body of the phone?
Yeah, where the black part ends.
Also, I have removed it and replaced it on more accurately since then and noticed it sticks to the screen very well, even attaching itself to parts that I have not even smoothed my fingers over yet, must be the static? Are there any disadvantages in using this as opposed to buying a new screen protector?
If it works then continue using it. We don't get them pre-fitted in the UK so I bought a 3rd party one

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.
Hi,
first of all i will start with saying that I suppose I am not entitled to the official samsung warranty or customer service, as i bought my phone form ebay (unlocked version, shipped from Hong Kong). Unfortunately in my absence my younger brother managed to lightly scratch the screen when he was playing with it, he got scared and tried to get rid of the scratch by rubbing it with toothpaste (it's something he read on the internet, supposedly it was supposed to "polish" the light scratches and get rid of them). Of course it didn't work, and just made it worse. In fact it created a dull, round spot on the screen just where the scratch is, it was hard to clean and attracted moisture easily, moreover when screen was on you could notice a grainy/greasy spot. I guessed, that the toothpaste must've removed the oleophobic coating on the screen, so I thought i will buy a oleohobic coating kit, which i did. I went to Amazon and order the Crystalusion Liquid Glass, praying for it to fix it. After application it restored the hydro/oleophobic properties in that spot, and made it smooth just like the rest of the screen. Unfortunately the grainy/greasy effect while screen is on remained, and under direct light you can still see the dull spot, so i guess apart of removing the coating, he must've sanded the glass underneath it. I am thinking of putting a second layer of that liquid glass thingy, hoping it will fill the sanded pores, and smoothen the glass even more, maybe it will do the trick. It's not something that disturbs the every day usage, but i just cant get over the effect on the screen when its on .. and just the knowledge of not having a perfect, beautiful infinity display just after 3 weeks of having the phone is making me cry. And yes, I know i could use a screen protector .. I've tried those, and none of them suited me, first (samsung original) was not compatible with the case, and next two (wet application) ruined the screen quality (created that mentioned greasy/grainy effect on the entire screen), and after all the TGP reviews I decide just not to waste money on them, so i decided to go naked screen+case ... Do you think there any hope for me? Any ideas on how to fix it, or if it is even possible? Do You think that i can contact Samsung with a device bought on ebay? I will be grateful for any answer, and sorry if this is not the right place for this kind of thread.
Well it won't be covered udner warranty because it's damage caused by you. It's not a faulty product.
But you can maybe have it repaired by Samsung. They can replace the display with a new one. But this is quite expensive.
Putting a screen protector on might help mask the marks on the screen and make them less noticeable.
Hi guys! I have an issue with my screen on OnePlus 7 Pro, and I'm not really sure what this is. I never had a thing like this on other phones, my OnePlus 6 had a few scratches, but they never behaved this way. And the thing doesn't even look like a scratch but more of a huge print that doesn't go away.
Here is a picture - imgur.com/a/Smb6rvF After about month of having a phone and it always being in the case and with the default screen protector I've started noticing the image distortion in the same place from time to time, you know like a huge fingerprint or grease on the screen but it would appear at the same place. I thought okay, maybe I've scratched the screen so that I can remove the screen protector and it should be fine. So I did, but the thing stayed there as if it was either placed through screen protector or from the other side. And again, it's not that I never saw a scratch or a crack on the screen, but never this thing.
Then after about a week, the thing grew, you can see the blue line here - imgur.com/a/UI4FQTA
the red one was the initial one that I saw even with screen protector on, and the blue just grew out of the old one. Like I pull the phone from the pocket one day, and it's there. And not like I'm wearing and tearing the phone, just regular stuff - in jeans, inside pocket of the jacket, in the sealed pocket in the backpack. And I live in a big city, and I never notice any sand or small particles on the screen or the case. And it doesn't look like a scratch, but more as if the prints just bound to the screen and don't go away.
imgur.com/a/OnPSqj2 - is a more closeup shot. And again you wouldn't notice the thing at the start of the day when I clean my screen, but by the end, it will collect some grease and more prints and will be showing.
Here's a video what happens when I clean the screen -

FYI warranty or anything like that is out of the question since, I bought it during the holiday travel, and the phone is not officially sold in my country. I just wanted to know if there is any solution for this and how to prevent this from happening? Are these scratches but look different because of the new Gorilla Glass version or something like that?
Any help or advice is appreciated, just sad a thing like that happened so early in the life cycle
