[Q] Problem with NOOK HD+ LCD Screen distortion - Nook HD, HD+ Q&A, Help & Troubleshooting

Got my NOOK HD+ a few weeks ago and I have been really satisfied with it. I love the big screen and how smooth Cyanogenmod runs on it.
Yesterday I noticed that if I apply SLIGHT pressure on the plastic sides of the NOOK (not the screen!) the lcd distorts. With distortion I mean that the LCD fluid gets visable and you see white marks (just like oil on water) on the screen. Those disappear when the pressure goes away.
For those of you who might say "it is a touch screen, not a press-incredibly-hard-screen": I am really not pressing hard, just e.g. when you hold the NOOK with one hand - there is automatically pressure where your hand holds it.
Now: Have any of you experience that too? I know that LCD screens do that. I know how they work. But is it normal that I get that effect when I barely put pressure on the sides of the NOOK?
PS: For those who still don't know what I am talking about, this video shows this effect pretty good (even though the guy seems to press really hard ON the screen): https://www.youtube.com/watch?v=DPtwGfzchA8
Thanks in advance. I just want to know if you guys thinks it is normal or of I should start flashing stock and claim a replacement.

Well I also have this "problem", I think it's normal.

Okay. Thanks for your reply. Really strange, but it makes me feel bette that the problem is out there and it's not only my device.
Today I noticed the bezel on the top right corner is coming loose, you can see between screen and bezel (around 2mm).
I called customer support and they said both problems should not be there and I will get a new NOOK in a couple of days.

Well, LCD distortion is there for all LCD screens(I'm pretty sure). About second problem through, yea you should get it replaced.

I thought so, too. If it were just for the distortion, i would have lived with it. But when I noticed the bezel coming off, this was another sign to get a new one. I just bought it like 2 weeks ago. Shouldn't happen IMO.

Broken Diamond display, or what?

Hello there, XDA.
This thread is more for an ensurance for me that I've done nothing wrong when using my phone - and it might show up that some other people have the same problem as I do.
Now, to the thingie. Bought a HTC Diamond about 3 months ago - working just fine. Although about 3-4 weeks ago I realized that when I tilt my screen, I can see some crazy stuff going on... There is two pictures attached and linked to further down.
Anyone else has this problem? Would be lovely to hear what you've done. I sent an e-mail to HTC and the manu... manufactourer-/or~ (spelling :b).

That just looks like moisture between the screen protector and the screen itself.
Odd that it's in a perfect rectangle. I've seen this before on a mates LG Viewty (Horrible phone!), but he never followed it up so I don't know what the cause was. It did have a touch screen, but no protector. Perhaps its moisture actually in the screen or a manufacturing fault?
Good luck.
Oh my - I had rectangle on the screen today when I removed the protective front later (brand new phone).
Though It's no longer showing I'm scared its going to become more apparent and eventually become like this.
What is going on with QA and HTC?
There was another exact case like this that I saw this week. Can't really remmeber but do a search and you will find it.
I have the same thing on my Touch Pro, and another user has had the same problem on his (her?) Diamond:
http://forum.xda-developers.com/showthread.php?t=428262
Unfortunately it isn't moisture below the screen protector, but that the touch resistive layer was subject to heavy pressure (eg: being squeezed in the pocket). It shouldn't affect anything in the short term, but in the long run the touch screen might become erratic or imprecise, so you should keep an eye on it.
The store I bought my TPro from doesn't accept returns/exchanges, and so far HTC hasn't replied to my support ticket. Unfortunately I think some of us are going to be left out in the cold. Personally I'm tempted to buy a replacement touch layer and replace it myself, but of course that would void the warranty (even though it doesn't seem to be doing me any good).
If this becomes widespread, there could be a chance for a class action lawsuit (hopefully HTC will wise up and help us out before it comes to that).
Ouch >.<, feeling sad (but somewhat a bit of relief) that some others has the same problem.
Yes, the rectangular shape is very, very odd - since that makes me think that just pressure can create this mess. It feels more like a manufacturing fault.. But, as for fhsieh, HTC hasn't respond to my support ticket.
Wondering if I should call them to get a direct answer.. Hm.
I've suffered this
But in a Touch Cruise I own before. I thought, as said, that this regular shape can only came from a pressure problem.
Loosing my warranty (due to the long time to be repaired here in Spain), I opened it, confirming that was not a problem with moisture (at least in my case). Also I saw the resistive layer poorly sticked to the body, with zones unglued, causing the layer to raise, specially in the bottom edges. This bothered me a lot, because I ended with lot of dirt between the layer and the screen itself, unable to clean.
Maybe that was the problem. If the layer is not correctly assembled it gets an irregular surface (as lightly squeeshed) , yielding this. But, functionally speaking, the screen was performing well, as it should be.
Hope this helps.
It's only humidity... it happens also in my diamond... try to dry it under the sun..(not so good for lcd but it works for me)..

Yes, it's due to the prefect pressure of the screen, exactly in the center..if you try to press a corner for example near to Start button (with screen off) you should see the spot follow your finger's pressure. So there is a small drop between LCD and screen..(for me)
I had same problem in polaris. Send it for warranty as this is manufacturing fault. Why keep ****??? its htc s fault!?!
Well I thought i was the only one who had this problem till I came across this thread.... it's quite weird it's in a perfect rectangular shape anyone tried removing the protective screen and checkin whether it is the display... but one thing you hve to notice once the display is on we can't see tht on the screen only against a black background can you notice it....
It is the problem of screen protector. You may not see this watermark after you take off the screen protector. Try other good screen protector like Brando, Martin Fields ....

I tried removing the screen protector and the rectangular shape is still there then I put it in front of an A/C cooler unit and it went away!!!! then after awhile it returned back and the place I live is very hot and humid so I guess it's weather which plays a role....

Checkered prints on screen

Hey guys, I got my Nexus One earlier this week, and I love it so far, but I have some issues with my screen.
There seems to be a checkerboard kind of print on it. I can't really explain it any better than that. At first I thought it was maybe residue from the plastic wrapping it came in, but after a week and some thorough cleaning, it's still there.
It appears to be finger grease, which indicates that there's a problem with the glass. After cleaning it with a microfiber cloth, the pattern is gone (or at least extremely hard to see), but after some use, it becomes clearly visible again. To me, this says there's extremely small deviations in the glass, which finger grease gets stuck in where it isn't removed by a quick wipe down. To further support this theory, the screen seems more rough swiping top to bottom, than bottom to top, which would make sense given the pattern.
Edit: After thoroughly cleaning the screen, the breathing on it (like a window), my breath makes the pattern clearly visible. Though, this doesn't really confirm anything.
Has anyone else had or seen this issue? Any recommendations on fixing it, or should I be calling up HTC?
I'll try to take a picture when I get home from work, but I doubt it'll be visible. My only other camera is an iPhone.
I think what you see is the digitizer. It is barely visible but you can see it on every touchscreen phone

Not to be one of those guys, but I never saw the digitizer on my iPhones, until I got my Nexus One. Had a moment of uh, my phone's screen is really going to be like that? until I realized what it was, and now I only notice it at an angle in bright light.
You are right, with you can see it I meant just in theory.
I saw it the first time on an n1 too, but only once or twice, but never saw it again since it is so barely visible

Yeah, I definitely knew what you meant. Just wanted to throw that out there.
It kind of sounds like your phone is suffering some form of Newton rings. In the phone world its when the front screen presses on the digitizer and creates light refraction, thus looking like oil swirls. My HTC fuze suffered this horribly and it gets worse over time as far as touch sensitivity goes. I would recommend calling HTC. My nexus doesn't have this issue at all.
I am wondering now if the shipping nexus ones have the LCD screens instead of amoled because of the shortage in amoled screens though.

I don't believe I'm seeing the digitizer. This is on the glass, not the display itself. It's visible on the bezel around the screen as well. I'll try to take a picture when I get home from work.
Edit: to be clear, it covers the entire front glass, over the display and the bezel, and is clearly visible even with the display on.
Strange issue. Never saw this when I purchased mine, though that's probably because I was excited to turn it on rather than inspect the body.
I think it probably has to with the adhesive material between the digitizer and the display not completely curing. When it does cure you don't see it very well but when you use the phone and it heats up the pattern comes back. At least that's my theory.
Sent from my Nexus One
Took some pictures. For the sake of size, I'll link them.
Full screen, off
Screen edge, off
Screen edge, on
These are pretty accurate, in terms of what daily usage is like. The full screen one might be a bit much, I had to hand print it up to get it to show in the picture, but the one with with the display on is pretty much what using it (indoors) is like.
I've seen that sometimes on my phone, but it's not nearly as often as it seems to be with yours. Not sure what that is then.
I had a problem with my screen that can only be described as similar. One of the replacement Nexus Ones I received had an incomplete oleophobic coating where the entire bottom 1/4th of the screen would be very clear and the top would get cloudy after light use. There were also a few circles just like the bottom of the phone on the upper portion as well.
I called HTC and they just replaced it for me. Sounds like you should do the same.
Whoa, those look like the glass was machined improperly or that the adhesive issue I hypothesized about earlier could be the culprit.
Contact HTC or Google at 1-888-48-NEXUS (63987).

Thanks! Just got off the phone, they're going to replace it. Also, I can't believe how friendly/helpful they were. I'm extremely impressed.

Same here, they're extremely nice.
I wanted to get a replacement battery since mine has short battery life and constantly overheats, so they forwarded me to HTC but unfortunately for some reason they didn't have my IMEI or S/N on their records, so I couldn't do anything.

Creaky hardware?

Is anyone having basic build quality issues with the NC hardware? I just exchanged my first one because it had a mushy power button that didn't click, and the replacement i find makes a creaking noise whenever i grab it by the left side. I know it's going to drive me crazy if I don't exchange it again.
I haven't experienced any of those... in fact I find the construction to be quite solid. Bad batch maybe?
I returned my first Nook Color because there was a dust speck in the screen. I couldn't rub it out and it kept bothering me so I brought it back to B&N and they gave me a brand new one. I wonder what they will do with the one I gave them. Everything seemed to work except that one dust particle in the screen.
Mine had a dead pixel which awoke after a bit of use, but other than that (and I'm picky) it's been really solid. The touchscreen is a bit wacky at times, but that could be me - I have extremely dry skin and that can cause issues.

Funny, I am having the exact same issue with my NC. Creaky left side. Kinda makes a 'click' noise in about a one inch spot on the left middle by the screen. Kind of annoying but I suppose I'll live with it..
Definitely experiencing the creaking as well, and now I am noticing the back left side has some 'give' to it, allowing me to actually push it in slightly. The right side is perfectly firm. Anyone else notice this? Only had it for a few days, so if this is an isolated issue I will return/exchange it.
Thanks
+1 mushy power button here too.
no dead pixels though so I think i'm going to keep it.. I've got 'QuickBoot' installed anyways as a workaround
Mine is creaky, too. Everything that matters (to me) appears to be working well.
The top frame may be a 'snap-on' thing that snaps-on from right to left resulting in a bit of a space on the left side about a 1/3 of the way up. I'm sure most folks are sensing/feeling/hearing the 'creak', especially when moving through different ambient temperatures.
Touch and squeeze most of your devices (notebooks, phones) that are composed of different materials, e.g. plastic and metal, and, more than likely, they 'creak', too.
I have the creaking too. I thought about exchanging it but I don't really notice it anymore.
I returned my first nook color because of the creaking on the right side. It only happened after the device warmed up.
The second one is now doing the same thing on the left back. As much as I love it, it doesn't seem very solid.

Yeah i've got the creak top left corner. Doesn't bug me much but I do plan on keeping an eye on it.
I've got the creaky left side too. It hasn't bugged me too much, but the USB cable did catch on fire when I plugged it into my Nook this morning.
So that was fun.

The first NC I brought home had a dust particle right in the middle of the screen, too. Exchanged it, and the new one creaks right below the N button. No power button issues, though!

I'm thinking of returning mine too. I have creaking. Anyone else have a bowed panel where the home button is? The left side is about a 0.5 mm lower then the center and the right side is about 0.25 mm lower then the center.
Such a shame. It is nice device. Its the best built android device I have seen.

Seriously, the USB cable sparked and caught fire when I plugged my Nook Color into it this morning.
It didn't appear to damage the Nook, but the USB cable end is burnt and blackened.
Needless to say I'll be taking it back.
I'll take some pictures in a bit.
Took some pictures, I'll post them when I get 8 posts under my belt and can post pictures.

You know, that actually doesn't sound far fetched to me. For some reason the USB cable does not want to work in 2 of my known working USB slots. Windows gives me the standard "USB root hub has detected a power surge" message. So it wouldn't surprise me at all if it caught fire. I plan on seeing about a third party cable if I keep running into weirdness with it.

[Q] My Nook HD+ body and screen are a bit concave, anyone else?

I purchased a Nook HD+ last weekend and I've noticed that on the long dimension the screen curves a bit inward. More so on one side than the other. I carefully placed a straightedge on the surface of the screen and eyeballed it by looking at light that leaked through. Observed light shining through between the surface of the screen and the edge of the straightedge at the middle of the screen. Worst case is about 1mm. If I look down the long edge of the body a slight curve is plainly evident.
I went by the store today and looked at all the display models and a few were much worse than my HD+. Salesperson agreed with me that it was what he was seeing too. Then said, "I have one and I've never noticed that before."
Whatever! Anyone else notice this on the HD+?
I asked about a replacement. Salesperson was not eager to do that. I still have a few days to think about that. Frankly I was a bit peeved. If no one else here has observed a concave screen, I'll insist they replace and make certain to get a straighter / less concave one.
I did a reflection test with my Nook HD+ screen and did not notice any distortion, the screen is flat.
However, if the battery is swelling a bit that might explain the distortion. And if the battery is swelling, I would insist on a replacement!

Mine has no curvature of the screen, but does have a very slight concave curvature on the left side just above the hole. But that is where I put my left thumb when holding the device in my left hand, so it is probably compressed a bit from hours and hours of holding it. And now that I look again the right side has a very slight concave curvature.
I have two devices and just looked at the other one, which is older, and it has just a slight curvature on the screen and distorts reflection just a bit. And both sides bend slightly.
I hope you have not caused me to be distracted by it now. LOL.

I don't see any curve in my display (shipped last week from bn.com). I agree, thanks for the mods & extras & warnings about what to backup and what not to do (write to system) :good:
Update
Took the concave HD+ back and got a new one as a replacement. It is "straight" BUT almost every time I tap on the screen near the N button it makes an annoying sound. AND, something else, the bezel that surrounds the screen to the left of the N button makes a snapping/popping sound if you're holding it there and then release it. Like something is not glued or assembled right. At any rate something isn't right.
Yikes, back to the store again before this Thursday and the end of the 14 days.

I have the same problem you are describing. I am not sure if I should get it replaced. I have already sent my NOOK back once, because of a loose bezel and a LCD issue.
Did you have luck with your third NOOK? What would you say - should I get a third one?

I finally got one on the third try that was satisfactory (relatively non-concave and no popping/cracking noise) and have had no problems since then. I think if you're not happy B&N should take care of that.

Okay, I was able to get a new one. It was the last one in stock. I tested it in the store and it wasn't completely flat either. They guy said, he doesn't know why - hasn't happened before. He also said, he isn't sure if BN will produce anymore. They won't get any new ones. So I took the new, bent one.
The device is working fine, just the body is slightely bent again.
Well, I will have to live with it. I don't want to send it away and maybe just get my money back, because they stopped making the HD+.

[Q] HTC One light in corner of screen - Worth replacing?

Hi, I just bought the HTC One and I'm absolutely loving it. However, upon unboxing it, I inspected the phone and noticed that the screen is not flush at the top. I was fine with that but I've been watching videos and I've noticed light leakage under the front facing camera. Coincidentally, that's also where the screen starts to lift up a bit. Is this going to get worse and should I go and replace it?
Thanks

this is a "known" issue, it's called backlight bleeding. many devices suffer from this (some more, some less). it's up to you if you want to get a replacement, i didn't replace mine because i don't notice it very often
