LCD "Mura" Defect (aka, clouding, hot spot, white spot) - Asus Eee Pad Transformer Prime

My Prime has developed a small bright spot in the center of the screen. It's only visible on white or light pages. I didn't drop the tablet or anything, it just appeared. Anyone else experience this?
EDIT: Here's a link showing a laptop with similar looking spots. The one on my Prime is much smaller than any of these, but it's a similar looking mark. I tried getting a picture of mine, but had trouble doing so.

EDIT2: I've learned that the defect I'm talking about is called "mura," or "clouding."

I have 4 of those spots.. three are within one inch and one of them is at least 3 pixels. I also have poor wifi, so I want to kill two birds with one stone. as soon Asus has a fix for the wifi I will rma..

I have the exact same "brighter" spot at lower center of the screen, don't remember it being there when I first got it... it's very annoying, I think I will send it back for repair.

My friend's first prime had that on his screen (2 white dots) when he bought it only visible on a white screen. He returned it for a new one. Thats why its important to check for those too when you first get your prime and put it through inspection, Just open up the notepad like app, that one has a white screen.

got one too. need to send it back for repair, just been too lazy to do it...

Read somewhere that those are stuck pixels. There's an app in the market that's suppose to fix stuck pixels as well.

I'm 100% certain the spot wasn't there when I first got the tablet, as I did a very close inspection of it. Actually, I was reading through a thread in an iPad forum and there were reports of spots like this showing up on some iPads after a while.

Thanks, but this is different than a stuck pixel, which I also have (I found the stuck pixel when I first got the tablet, but it's so unnoticeable 99% of the time that it doesn't bother me). The link below shows similar looking bright spots on a laptop (the spot I have is much smaller than any of these, but it's the same type of spot).
http://pics.livejournal.com/laptop_mechanic/pic/000p062e

same story here. my prime has 5 bright spots (hot pixel) as well. i did not notice them when i got prime last year. pixel fixer can't fix these either. i can live with these spots though.

I have the same problem, 1 bright pixel just below the home screen indicator.
It doesnt bother me that much, its the only problem i have with my prime and knowing theres lots of people with more problems im not gonna return it for a new one, having the chance to get one worse than i had...

My phone had the same thing when I first received it (still does), but it was my understanding it was a "hot spot" created by adhesive or undue pressure in manufacturing. It's not stuck/dead pixels, in my case at least, and my Prime has no such spots.
I however don't know what would cause something like this over time. Seems to me something in the screen is poorly manufactured and overheating...

Sent mine back and was told by Asus that the white spot is a kind of light bleed that caused by pressure at the area, they will replace the panel for me.

I've noticed that mine has a few white spots similar to who you guys are describing. Mine has two about an inch apart from each other near the lower left-middle of the screen, and another near the right hand side of the screen. I don't notice it when other colours are present, but on a white/light surface, it can get very annoying. I'm thinking I might call ASUS and see if I can get it RMA'd since it has other problems as well. The WiFI is actually pretty ok, but GPS is a total bust. I don't really care about the GPS that much, but it might be what I need to send this in. I'm just worried the white spots will get worse with time.

After reading up on this a little more, the name for the white spots we're talking about is "mura" (google "LCD mura" and you'll get some hits). It looks like it's somewhat common on cheaper displays.

Also have this appearing on mine and also didn't have it before.
I have only noticed it in the last week since I installed the latest update.
I only really notice it on the XDA site.

In my case it's definitely not mura (clouding), but more like pressure spots or pinpoints (usually 2-3 pixels in size.) They are more distinctive in shape than clouding. Either way, sucks for any of us to get these kind of issues. I've actually got an RMA # for mine and will be sending it out either tonight or tomorrow whenever I get a chance.

this can be mura, spots, poinpoints or w/e
i can tell you another one..... so i was working very hard on many several things on my tfp.... sending emails, writing proposals, getting images, working on ideas ect.
I started to get annoyed on how fast the tfp goes to sleep, so i decided to put it to Never. So it never went to sleep and it was awesome because my concentration kept going and i was jumping from my laptop to my tfp back to my laptop ect.
THEN.... i decided to go to sleep and i left my tfp opened connected while it was charging. I completely FORGOT that i had disabled tfp from sleeping. So it sat on the Home screen of my launcher.
When i woke up several hours later, i started to use my tfp and i noticed there was a white area that on every screen it was still there.
It was the outline of the icons! This is the reason why screensavers we're created so this wouldnt happen. This is an excerpt from our trusty wikipedia: (btw, apparently this isnt suppose to happen in lcd's but i assure you it happened to me on my tfp, its not that bad though, as i barely see it sometimes)
Before the advent of LCD screens, most computer screens were based on cathode ray tubes (CRTs). When the same image is displayed on a CRT screen for long periods of time, the properties of the exposed areas of phosphor coating on the inside of the screen gradually and permanently change, eventually leading to a darkened shadow or "ghost" image on the screen. Cathode ray televisions, oscilloscopes and other devices that use CRTs are all susceptible to phosphor burn-in, as are plasma displays to some extent.
Screen-saver programs were designed to help avoid these effects by automatically changing the images on the screen during periods of user inactivity.

So, let me ask you this OP, did you by any chance leave your tfp on for a long time with something on the screen? and the glow that you have now resembles that image/icon/object you had on the tfp?
If that happened to anyone, hit the thanks

Nope. I can say with 100% confidence that I didn't leave anything displayed on the screen that could have caused this. The spot is very small, and is just a little random blotch that doesn't resemble any type of image/icon/object. I've tried taking a picture of it with the camera on my smartphone, but I get those vertical bars that you get when taking a picture of a computer monitor and it's hard to make anything out in the picture as a result. Would using a regular camera allow me to get a good picture? If so, I'll see if I can borrow one and post a pic.
Also, the spot wasn't there when I first got my Prime, and it appeared after about a month.
As of now, I've decided against RMAing it, as (1) I'm afraid of getting back another unit with one of the other myriad of TFP problems, and (2) I don't feel like being without my Prime for 4-6 weeks.

Add 1 to the of people with the pinpoint brightness issue, mine showed up after about a month of use.
I am also waiting to RMA or exchange at BestBuy once he seem to have all of the issues worked out since I have one of the relatively good ones now and don't want a broken one.

dead or stuck pixel
i have almost a half inch bar worth of dead or stuck pixels with more grey tint cloudy looking smugges..on the top portion of my screen..i can only see this when the screen has grey or anything in the grey family. i have not dropped, got it wet, or anythin to it..its been working great for me until about 4 days ago. how and what do i do about getting a rma. i have emailed asus but stilll not heard back..its realy starting to piss me off..this is going to be my 3 one..the other two i was still in my return time at best buy and game stop..this one i am not..any help will be great..would post pics but when i take the pics its hard to see or tell what i am talking about..

Got my transformer, two small bright spots on the screen

Two small pinpoints of white light on the screen. Are these dead pixels? Stuck Pixels?
I'm guessing that either way I should exchange it. So, apparently Asus is going to be having quality issues?

its a dead pixel
return son!
No dice. Thanks anyway.
Guess this bad boy is going back...
I got a replacement Prime yesterday and thought everything was perfect until I opened my web browser to google, which is pretty much all white and noticed a bright spot like you are describing in the title. Mine are definitely NOT stuck/dead pixels. I know because I returned my first one in part because of stuck pixels. It's almost like these pixel(s) allow slightly more light through than the adjacent pixels. Sort of like light bleed but not at the edge of the screen. I can only see it on white or very, very light backgrounds. It disappears entirely on darker colors.
It is unfortunate but I will not replace this again for a third time. It goes away unless my Prime is charging or docked (which I assume is because it is similar to the tablet being plugged in) and can only be seen on an all white background. I will never use my tablet plugged in, I charge it at night when I sleep, and the limited amount I have it docked is not an issue since it only shows up on an all white background and seems less noticeable than a dead/stuck pixel. Honestly, a smudged screen is more noticeable/annoying. Since I don't use my dock much it will probably end up having a dead battery anyway which means I really wouldn't see it much, unless the battery in the dock is required for it to function while attached, I'm not sure but will find out. Thinking about it I guess it probably does need to be charged for the ports and everything to work unless it leaches off the tablet. Who knows...I'll test it at some point.
It is kind of strange though and I really dislike trying to justify a flaw to keep a $500 device but whatever. IPS screens have some nice benefits but they seem to have a lot of flaws too like bright spots, pretty bad light bleed and more stuck pixels than I am used too. I went back and forth in my OCD head so many times about how many times I would exchange or return this device before I get one that is pristine but if I return it there is nothing else that interests me.
Asus had quality issues with their past Transformer and to think the 1080p tablet will be any different is ignorant.
Anyway, end blog. Since that's what XDA is now

If it's only 2 pixels and they are not directly adjacent, it's unlikely that they will take it back as that is deemed an acceptable tolerance for dead/stuck pixels. I think you need to have 5 or more total or 2 directly adjacent.
Pretty much all manufacturers use this guideline I believe. I hope I am wrong and you do get to exchange it.

I had one dead pixel on my Xoom and Best Buy replaced it without even turning it on to verify
I had two stuck pixels when I first got my Prime. Running pixel fixer apps didn't fix the problem. However, both of them have "unstuck" themselves after a few days of use. If you have some time before you have to return it, you may want to wait a little.
EDIT: Check that. I just ran a dead pixel test and only one of the two unstuck itself. The other one is so unnoticeable to me that I haven't seen it.

Same issue here, bottom right of the screen, small patch of white light in the browser window about an inch from the corner..
Not sure whether to return, the rest of the tablet is awesome!!
I just got another one and about 7 dead pixels the kind you can see on
Black screens and also slightly a bit of light bleed where the headphone jack is

Screen Burn... (Image Retention)

I am on my second Prime and discovered that my second one had some nasty screen burn. Short story... My first Prime I received on 12/27. UPS damaged it by dropping it on a corner, which is Best Buy's fault for only wrapping my Prime in plastic. This Prime was perfect.... no dead pixels, no wireless issues, typical GPS issues, no major light bleed... it was just damaged on a corner thanks to UPS.
I got my new Prime on 1/3 after doing some *****ing to Best Buy execs. This one I noticed right away that there is a slight light bleed on the right hand side (landscape) and 2 dead pixels. 2 out of 1,024,000 pixels isn't bad IMO, plus they were on the edges.
Now, last night I was watching The Devil's Rejects and noticed something funky on the right hand side of the screen (landscape mode obviously). I found a test color that shows my nice problem a lot more clearly... I wish I had something to calibrate the color more precisely to make it show better... Needless to say, I'm PISSED after discovering this thing has screen burn after only a few hours use!!! WTF!? I almost never use it in portrait mode and the brightness is almost always all the way down (auto brightness) because I'm by a lamp.
Here's a picture that I took. My sincere apologies, as taking pictures of LCD's is quite difficult without them showing up all messed up.
CLICK IMAGE FOR A BIGGER VERSION...
I can't get it to show up on camera, but it is clearly the black bar that holds your back, home, etc. buttons, as well as the time. You can see these burned in to this area of the screen.
Has anyone else had this problem yet? Looks like to me I'll be in for Prime #3... Maybe I'll just wait to see what CES has to bring, since I'm not getting what I want out of the Prime.
wow, that's bad... I have not come across anything like that (yet...) and hope that i never do!
I use my Prime right side up (with logo at top) during the day, and then at night when i'm home i use it upside down (logo on bottom right). I haven't noticed any status bar screen burn in yet... But I have always wondered about if the honeycomb status bar could burn into the screen, I guess it really can (and it scares me).
I hope you have better luck with #3. I have never seen status bar burn in on a tablet before but have always thought it was possible because of the way honeycombs status bar is always in view.
I was scared of that as well, but I figured LCD technology has come a long ways and there is no way it will burn in quick. My 3 year old Samsung 46" ToC has had stuff sit on the screen for an hour or two at a time, and I have zero burn issues. Same thing goes w/ my monitors. They've had stuff sit on the screen for 10-15 hours and I've not had an issue. I just really wish the status bar would hide so I can use the full real estate of my tablet and also prevent this issue. I've heard that BB is getting some of these in this weekend, so I may try an in-person exchange. I hope that rumor is true...

The last time i had screen burn was on my first ever LCD HDTV (from polaroid lol). It was cheap and over time it has bad screen burn.
Something is def up with your primes screen... 3rd times a charm
yeah, your best bet is exchanging it. never heard of screen burn in on a tablet before. I think you the first to report this.
Damn, xda duplicating my previous post...
Anyways, If your unhappy with the way you received your prime from BB get a refund. Order from Office Depot, mine came in a white padded bag and ended up being in perfect condition with no defects at all.

The only other device that I have screen related issues with, is my Samsung Captivate. It has ghosting, which goes away with you changing whatever is on the display. I know for a fact this is a burn pm the Prime, since I watched another hour of the movie afterwards and did all kinds of other tasks today, and it doesn't disappear. Kind of disappointing.

What is likely going to keep me at BB, is the fact that I got a credit because I *****ed to execs about their crappy customer service.
I was using the pad heavily last night during the playoff games and my screen burned. I also noticed that a pixel died. It wasn't there when I first received the device. I'm not trippin because it is going back on Monday because of the "no serial number" issue.
This happened with my first one. I ran a pixel fixer over night and the status area was present the next day. I don't think this is screen burn though. It will go away after awhile if you use the tablet in landscape or whichever way you were not using it. I think it's called image persistence. It has to do with pixel charge or something.
Bring up an all gray background and you can really see it.
I'm waiting on a replacement due to stuck pixels and busted vibrator.
After several days of letting it not go in portrait mode, the bar has somewhat gone away. I did go ahead and used it for about an hour in portrait mode on both edges, and the opposite side had no problems with burn/ghosting. The original problem edge regained its problem right away. I would point this to not be a "burn" but rather a sort of long term ghosting. I'm highly disappointed with this one not only for the ghosting, but also several dead pixels. I'm up to 2 that won't turn black and 1 that won't turn colors. The one that won't turn colors is quite obnoxious.
I've been trying to contact Best Buy in regards to exchanging it... but I'm not having any luck with that crappy company. Ugh! All they tell me is I can return it and get my money back, exchange it in the store, or send it to ASUS. Option 1 is a no-go since I got a credit for my first troubles. Exchanging it won't happen since the stores don't have it, and their exchange policy is 14 days. The last one won't happen because I just bought this and I don't want a refurb a week into ownership.
This phenomenon is known as "image retention" and any early gen plasma tv owners will be familiar with it. why its cropping up here....i have no idea. my prime does this, for sure...its most noticeable when going from speedtest app to xda, which i have done a lot of..haha...anyway i have xda set to the black theme, and i see a very prominent white retention of the ad at the bottom of speedtest for several seconds after flipping back over to xda. I've seen it in a few other places, but it always goes away pretty quickly.

Damn, didn't think I'd have to worry about burn in/image retention on a mobile device. Picking my Prime up today and now I'm gonna have that same paranoia I always get when I buy a new HDTV, but even my last two Plasmas never had any real problems (Panasonics). Hopefully this winds up not being a big issues though, sounds like I'll be getting insurance on my Prime after all and just doing arbitrary returns from time to time.
This was one of my first worries when the galaxy nexus was rumored to have on screen buttons rather than cap buttons. I thought amoled screens did get actul burn in. I didn't think it would really happen with these but it is a drawback of ips i guess.
I just wanted to tack this on, since I got a 3rd prime yesterday. This Prime I'm overall happy with, however the image retention still exists on this one. S/N is a BC batch, though I didn't grab the last one unfortunately. I will say this... this Prime's image retention happens when the screen brightness is at like 50% (no IPS+ mode). I flip to another app with a color, and I can see the retained image. Now what makes me quite a bit more happy about this one versus the other one... the image retention disappears after about 2 or 3 minutes. I definitely was not noticing it on a brief watch of the same movie that I noticed the image retention on the first one. My last one held onto the image for days at a time...
Overall 3rd time is a charm. Zero deal pixels, minor light bleed that you get with this style display, the feedback motor is quite a bit stronger, general GPS issues with every TF201, not noticing any horrible WiFi performance either.
I've noticed some minimal Burning over short periods when I have it screen maxed out and with IPS+ on as well and the screen with a fixed white bar or text . But then it goes away in five minutes once I change the image. Never gotten it to happen under Max brightness with out IPS+ or a white static image in conjunction.
I would return it. I also never keep anything static on my screen. Even my wallpaper is active and moving. I've seen LCD burn in all the time on desktop computer screens.
I saw something like this over the weekend.
I had it docked and was writing a blog post in Documents to Go. I spent probably about 3 hours on it. After I was finished with it, I noticed D2G didn't have a spell checker so I closed it and went into Polaris Office to see if it did.
Underneath the transparent gray of the file screen, I noticed something looked weird. I took a closer look and I could still see shadows of the blog post I wrote.
I turned it off and couldn't see any burn in the screen. I rebooted it and went back to Polaris and didn't see it after the reboot.
Now I'm debating sending it back for a warranty replacement.

[Q] Dust or dead picel under the screen

There are 2 pieces little spot under screen recently and they are located around center of the screen.
I am not sure if it is dust or dead pixel. It is not totally black but it is kind of grey color and it looks like between screen and LED. One is darker than another. They are not close together. The shape of the spots are not really a pixel square. It is hard to take a photo as it is small.
It was prefect before. And i just found it recently.
Anybody have the same experience?
I would like to change a new one if i cannot fix it myself
Yeah, I have a speck of dust on my screen as well. I can tell that it is dust because it moves slightly when I change viewing angles. I am not bothering with getting it fixed because other than that issue, my tablet works great and I don't want to risk something worse showing up.
I've got one small speck by my recent apps button on screen. I'm using a skinomi skin and sometimes it looks like its between that and the screen and other times it looks like its between the glass and the screen.
Noticed it the first week and havent seen it getting any worse or more collecting.
I also have this. 2 doors of dust or whatever slightly under the very center of screen and in the middle.
I also notice my metal near my port keeps bending in.
I keep debating if I should take it apart and clean it.
Bugs me seeing these two specs.
Doubt Asus would do anything to help us.
Sent from my Galaxy Nexus using xda premium
I have also the same probelm but only one for the moment.
I also have dust but I am afraid that if I RMA that I will get something worse.
It sounds like i am not alone. I am not able to move it...but i would like the way to proof if it is not dead pixel
Any method to clean it or move it to the side? It is kind of bother me everytime when i was reading something on white background.
I have a grey spot about the size of a pixel or two, but I don't think it is a pixel because the edges are not crisp. If it were a pixel I would think it would have well defined edges. I have a dead pixel on my HDTV and it is quite easy to see the edges of that.
It's so small that it doesn't bother me in the least..well apart from knowing my screen isn't perfect.
Also I see no parallax when tilting my screen so if it is dust, it's sitting on the LCD and not the gorilla glass.
I also have that "pixels" in the center of the screen. I see that I am not the only... That's weird. I think it's dead pixel. But I'm not sure... What guys think?
I tested some applications that can wake locked pixels with no success.
Could it be only dust?

I think i was one of the first to mention this before regarding any problems with my prime in another thread but yea i chose not to bother returning it and gettin one with bigger problems...its annoying sure but hardly affects usability and performance.
I'm OCD and my Prime I had gotten from Best Buy had some dead pixels, then another one I had gotten had a dead pixel AND a piece of dust or something under the screen... I ended up finally getting a good one w/o any problems so far. *crosses fingers*

LCD Mura

Has anyone else experienced "LCD mura" with their Primes, and if so, has the issue gotten any worse since you noticed it? LCD mura looks similar to light bleed, but not in corners of the screen. Rather, it is a small blotch/"bright spot" appearing anywhere on the screen. I have one such problem area that showed up after owning the Prime for about a month. It hasn't gotten any worse, but it's annoying on white backgrounds. I'm wondering how common of a problem this is. A Google search shows that it's a somewhat regular occurrence on cheaper LCD screens.
Ohhh, so *that's* what that is. I've had if for a while in one spot. Only noticeable on white backgrounds.
Yes had two such areas on my TF201. Had the sreen replaced under warranty.

What was the turnaround on the replacement? I have about 5-6 of those "white spots" now...
Have the spots come back after it was fixed?
My prime had 7 bright pixels!
They developed 2 months after I bought them..and kept increasing with time. These pixels will not go away with pixel fixer apps either.
Have sent my tablet for an RMA to get the LCD replaced. Fingers-crossed.

Sure, will keep the thread updated when i get it back. Only 5 days (3 business days) so far. RMA On "Waiting-[WB5] Wait for Repair\Test\Aging" status.
had 2 on mine, they didn't get bigger or anything. thought i could live with it and decided that since every time I saw it I was pissed so sent it in for RMA. Sent in March 26th (they received it) and was returned April 8th back in my hands. SOOOOO Happy I did I now feel like this is the tablet I should have always had. Also my time may have been extended by also getting bt/wifi fixed (well partially fixed, usable now)

I guess I had this on my TF101, A few white spots showed up, I sent it in for RMA, it came back and looked fine (they said they replaced the screen) but after a few months the white spots came back almost in the same exact spot. I sent it in for RMA a second time, this time they flagged it as CID (customer induced damage) I emailed Hai, and *****ed and complained saying they fixed it the first time and didnt flag it as CID, so why are they flagging it this time. The next day I got an email from Hai saying it was taken care of and was no longer considered CID, and was being repaired.. So it does seem the white spots return in some cases
I had one of these on my screen. LCD replaced in a day. But then there were other issues like them not connecting the screen properly so only half the touch would register. Ended up getting a refund.
Just noticed my second LCD panel has a developed light 5mm mura spot.
Not as bad as last time.
Same area as last time. Lower left corner.
Would be interested to hear where other's have found their mura spots.
I have a couple on my prime, towards the bottom of the screen in landscape - one is about 3mm by 2 mm the other about half that size - they do grate on your nerves once you can see them, especially as so much of what I do on my prime (kindle, email, word-processing, surfing the web) is against a white background. I've emailed ASUS and am looking into a RMA.
I had the same problem, right in the center of the screen, one bigger spot and two smaller.
Sent my Prime to RMA a month ago, still waiting for it. Seems that he replacement screen is not so easy to find, in Europe.
BTW, they not considered it CID, and they will repair it under warranty.
Update on my prime's RMA
My tablet is still in WB5 state for an RMA to fix 7 such bright spots. In multiple conversations with CSRs it was explained that other issues (unspecified) were detected after the repair, and the tablet is now waiting for some special components to be repaired.
I am still within 10-14 business days to repair period, so the RMA can not be esclated yet.
I regret having sent my tablet for LCD replacement. Will kepp posting any updates that I have.
I recall someone mentioning the below statement in some other forum...
"I hate apple. But atleast their Sh**t works and they support it"
How true!
FYI - I sent it to TEXAS repair center.
WTF! Just noticed a mura starting to form.....ughh every time I am happy with my prime I find something that P***es me off with it. I really want to love this tablet. I feel like I am prime-bipolar. Some days I am prime-manic and some days I am prime-depressed. /Sigh Asus why do you toy with my electronic emotions?

I'm noticing a 3rd spot develop on mine - begun the RMA process. I'm going to brace my self to be without my prime for at least a month. (I survived without it for 40 years, I'm sure I can go a month...)
i had spots on my first prime (BCOK) but exchanged due to GPS (also had haptic feedback issue too).
Second prime (c10) has a couple spots in landscape about an inch from the bottom of the screen near the center. I have "kept an eye on it" as far as noticing it only when I'm really on a white background or anything. I usually use it for reading and/or taking notes on PDFs so I surprisingly haven't been bothered by it AT ALL. I actually forgot they were there until last week.
Anyways, if it gets any bigger or I get more spots, I'll send it in over the summer...
i have a tiny 2mm area which is really white, when i have a whitish background. It is imposibble to tell though when i have other colours on the screen. My tablets serial number starts with a B so it was one of the earlier ones. It just randomly happened one day but its not that big of an issue
i had 2, if in landscape they were just off center down and left, and a little further down and left like middle of lower left quadrant was the big 5-7mm one that really bothered me. Decided to eventually send it in they received unit march 26 was back in my hands april 13th ish (can't remember) i believe
I don't know if this is my problem or not -- When I have a black/dark screen, I can see two areas that are whiter than the rest of the screen. It's not individual pixels but splotches. I do not notice it on white or any other color background? I haven't decided if I can live with it yet or not - still hoping it will just go away! If this isn't LCD Mura, what would you call it?

[Q] EVO LTE Screen Flex/LCD Ripple Issues?

Unfortunately my OCD kicked in and I returned my first EVO LTE as it had peace of dust under the screen and slight light leakage at the bottom. Other than that my screen never had any flex or ripple issues and I am regretting that I took it in for an exchange!! My 1st exchange unit had a pixel that was stuck in the on position and had seriously bad LCD ripple effect. Took that back to a different Best Buy and the second exchange also has this same LCD ripple effect. It is most noticeable on black screens if you lightly press around the sides like you are scrolling up and down a web page. It can also be scene on the home screen. There are several videos of a One X having this issue. Example: http://www.youtube.com/watch?v=1DmLNSiNT24
My question is, how many people have this issue? I am crossing my finger and hoping I can get a unit again that doesn't as I truely am pleased with the other aspects of this phone and can deal with the other small little hickups of a new product launch.
I have none of this.
my OG Evo had this after I replaced the digitizer. i assumed i did something wrong since the one before it did not. no issues on my lte
Limited sample of responses so far, but seems to be looking more positive than I expected it to be!
Maybe I have a better chance of my next replacement not having this issue than I thought! I hope it was just a bad batch for this area and the next shipment will be better!
Had same ripple issues
Hi..well I got my evo lte on a pre order. I ve had all the evos thru the last couple years and the LTE is a very good phone. I noticed the exact same thing,when I would gently push or tap on the screen it would have clothes of light that we're very bad,and on black screens that was even worse. I called sprint and they told me to go to a store to exchange it. I went to the store and the manager was awesome we sat down and he brought out 5 brand new EVO LTE s for us to try. At his amazement they all were as bad if not worse then mine on the ripple effect. I have a galaxy 2 touch and when we pushed on that screen no matter how hard it showed no signs of light bleeding or rippling at all. He didn't know what to tell me but did they say the screen on the htc should not do that at all and it might be a bad batch. To me it seemd the glass on the LCD screen didn't bond well with the glue they used,and when you pushed or tapped it would go down into the LCD screen. I know when you push directly on a LCD tv,computer screen it will give you the same similar effect. I called sprint and told them I was returning the phone and the lady in the return department told me she has had a few calls about people wanting to return the phone because of this issue. I really like the LTE,but couldn't put up with the screen issues. I am going to wait till the galaxy 3 comes out and also by then check out the EVO lte again to see if the problem has been fixed.
Sigh first off mine does this but I have to apply more force then is needed for the phone to register the touch. Second off WHY are you pushing with any kind of pressure to even do that? Now if you're just touching the LCD and it is doing this I understand. Also even in the vid it looks like more force is being applied as needed but not as much as I have to apply? That being said if you think sgsiii will be better well it will cause it doesn't use a LCD lolol.
Edit I think this is to have gorilla glass 2 which is thinner so chances of this happening are going to be common I'd assum of you push down on the screens lol.

From my experience I am not applying any more pressure than I would use normally. That is the only reason I noticed it. I was typing in my numerical pass code on a black screen and saw the ripples. I then did further investigation. The video might not be the best reproduction of how you get the problem under normal use, but it does show what the problem looks like. My first phone I actually used more pressure on trying to figure out what the dust spot was and never had this issue occur so had no clue what I would run into with an exchange. This is a production issue on some LTE's and One X's. The below comment was posted in an article on the One X in April. I just think some phones are much more noticeable than others and who knows what this issue will turn into over the life of the phone.

"Three separate models provided by HTC, and one by network Three, produced the issue, CNET UK said, meaning it may potentially be widespread. However, Daniel Hundt, creative director at One & Co., HTC’s design consultancy, said the company would never “let that ship.” Hundt added, “maybe this is not a shipping build,” referring to a unit CNET UK writer Natasha Lomas demonstrated the issue with.
TechnoBuffalo’s own Jon Rettinger and Todd Hasleton didn’t notice the issue when reviewing the One X, and chances are good the average user won’t either. The device really is one of the most beautiful phones out there. It also provided the best Android experience we’ve had yet, so this “screen flex flaw” issue shouldn’t deter folks from picking the device up. Still, we reached out to HTC for comment, and will update as soon as we hear back"

This is not something that will push me to an S3 though!
Ok well then that's a diff story and I'm wondering if it due to the glue not curing by the time it got to you... Or a lack of glue. Since the glue has apparently been a problem this time around for HTC lol. And glad to know you won't defect to the sgsiii. The one thing I don't understand is why Samsung uses the gn as a beta for their sgs line. Same screen on gn and sgsiii but its to be slightly better.(only cause they used the gn as a test)

Yep, glue on this current phone has the screen slowly getting white. Started out kind of yellow and now most of it is white with the bottom section still a little yellow. Going to give it till Friday to see if anything improves and if not I will test out the new shipment at Best Buy and try my hand at another exchange.
Update:
Went back to Best Buy and we opened up and looked at 5 different phones and EVERY single one of them had this issue. Some worse than others, but it was still apparent.
Not giving up though, trying a different store today to see how that works. I know my very first phone did NOT have this issue, just had a small speck of dust and slight light leakage..... I SOOO wish I had that phone back! Should have never returned it.
Update on my OCD - LCD Flex Issue:
5 Different Best Buys in two different states. Every phone I have tested had this issue to some extent (18 different phones tested). Some worse than others. I now believe my original phone had the issue, but was just less noticeable. Also, the screens normally do start out with more of a yellow tint from the glue. This mostly goes away after a few days of high brightness use, but sometimes a slight yellow band at the bottom remains. I think HTC doubled up the glue to help with the light leakage issues they are known for in the past.
Current phone has white balance closer to a pure white than a light yellow. (no yellow band at bottom either. This screen still has the flex issue but needs medium/medium heavy pressure to see on a black screen. I should never have to press that hard on anything to ever notice it. I am almost perfectly happy now, only bad thing is it does have one stuck pixel at the top of the screen (can't be seen on Pink, Red, Blue or Black, but is apparent on Yellow, Light Blue, Green, White and Gray). Would have never noticed it without the dead pixel test. I would rather have that than have it sensitive to the flex issue and any yellow tint to my white screen.
So, if you have not noticed the flex issue, then DO NOT look for it or try to reproduce it. You will most likely find it. Not a show stopper and should not be reproduced under normal use (Except for the few bad eggs that are really sensitive).
