[Q] Defective Replacement Screen - Nexus 5 Q&A, Help & Troubleshooting

Looking for opinions.
Ordered my 5 on day one. It had a stuck pixel and a little bleed. Probably should have RMA, but wanted to wait a bit. As luck would have it I cracked the screen before I got around to it. So I replaced it myself with this:

After 2 months use, the screen has rapidly deteriorated. I can even notice the defects in TWRP and on the boot screen. Doesn't TWRP kind of load it's own kernel? That kind of rules out any kind of software problems. Any suggestions for where to get a more reliable screen replacement? I sent the following to the seller:
Hi,
I carefully read the reviews on this product. Some claimed that the screen may not be OEM equipment and was not as pictured in the display. It seemed like a risk, but I needed a screen.
I have replaced many screens several of my devices and my children's devices. The swap was effortless. When I booted my phone with the new screen, it appeared to be a major success again. There were no dead or stuck pixels and minimal back light bleed around the edges. The only noticeable issue was a very bright area around the soft keys. Particularly on white pages.
The screen was installed in early April, and recently I have noticed it become gradually duller with an increase of bleed around the edges. Then yesterday, things got much worse very quickly. I noticed greenish bleed/band around all edges. The bright white around the soft keys is brighter. There is a 1/8 inch band around the top of the screen that is very dark. It is not very bright and the colors are dull. From previous experiences, I know that these are signs that it will only get worse.
One of the reviews talked about a similar situation: Looked great at first, and deteriorated after a month or so.
I would like to request a replacement screen for my Nexus 5.
Thank you.

[Q] Tiny black circles on screen?

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...

[Q] tf300t screen quality

hello,
Are you satisfied with the tf300t screen quality? I think the black on mine is a little uneven with really faint lines when the screen is completely black.do you think it is normal?
thanks
It would be way better if it weren't for the large areas of light bleed around the edges and corners! Other than than, I'm satisfied.
I get loads of backlight bleeding on mine. The screen as a whole (including the glass surface) seems a step backward from the TF101.
I just started noticing light bleed on the left and right sides of mine. Nothing major, only really noticeable on the loading screen and to a lesser extent, my primarily black wallpaper (a style I tend to favor).
Other than that, I have no complaints. Although, if I fire up Angry Birds Space and put it right next to my girlfriends iPad 2, it definitely does not look quite as nice.

My old Prime had some noticable bleeding several places around the edges, but that was only visible when displaying black and at a high brightness.
I've always hated light bleeding, and also uneven black-levels, but I always get devices with these errors no matter what... I've had 6 different LCD-TV's, and every one of them has had various problems with light bleeding / uneven backlight / black levels - so i started to think it wasn't possible to get it perfect, and that it was only me who was being too demanding.
However, my TF300T seems perfect - guess I'm lucky with this one
I just bought this tablet and there is one spot (about the size of my thumb, in the lower left quadrant of the screen) that shows up lighter against a dark background-- for ex. when it's booting up.
It's bothering me but I haven't decided if I'll attempt to get it exchanged (I could get a worse one?).
well,I just found a tiny little dot on the screen.It doesn't seem to be a dead pixel but a tiny hole in the polarizer...
On my second device. Traded my 16 for a 32gbversion when they first released them. My 16 screen was perfect out of the box, no bleed, no dead pixels. My 32 looks like a shop light when booting but i don't notice it during use. Watch out,the screens scratch soooo easy. Definitely pick up a screen guard, this isn't gorilla glass.

i can confirm this as well although it doesn't bother me at all, the scratches are light so you don't see them when the screen is on. i'd rather have a few light scratches then a screen protector since i always get lint or dust stuck under the protector, even when i'm extra carefull and this bothers me more than scratches.

LCD Color Bleed. Anyone else?

I wanted to wait a couple of days before calling it official, but it seems like my screen is suffering from color bleed. If you look at the attached image, you'll easily notice the bleed into the screen from the top edge. I'll be returning it tomorrow and getting a replacement hopefully by end of week. I basically lost out on the cost of the tempered screen protector that I have on the phone. Bummer.
I've had four Z-line phones in the past but never a single issue. I guess there is always first time.
I have the same issue, bleed from the top. Mostly visible on a blue or white background though. Is this a defect or does everyone else experience it as well?
Not refuting but I do not have this issue.

Dying screen

I'm on my 3rd Nexus 5 in just over 2 years. I've had this one since November and I'm obviously well out of warranty now.
Anyway, the screen looks to be failing. It has developed a large green patch in the centre and the backlight isn't anywhere near as bright. This seemed to happen instantly earlier this evening with it getting progressively worse.
I had replaced the battery a few days earlier. So I've been back in and checked all ribbons are seated correctly.
Would a new screen fix this or is it a different issue that is creating these symptoms?
Could there have been too much pressure put on the screen when separating the battery from the screen? I know the battery adhesive can be stubborn.
There was a decent amount of pressure but it was fine for a couple of days. If it is the screen they don't seem to cost too much to replace. Just don't want to waste my money in case it isn't.
Since the issue is in the middle of the screen, I'd be tempted to try a new screen as the screen connections are at the top of the motherboard.
I have replaced a few screens with third-party screens. I noticed that these third-party screens are not as bright as the original but it was not very noticeable until I held a phone with a third-party screen next to a phone with an original screen.

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.
