Lets hope because I really want to get one of these instead of a new phone... I was planning on spending my upgrade money on this tab instead of the phone... but I don't want to have this screen issue...
[Galaxy Tab 10.1 General] :
Hello guys, I'm very happy that things are moving on.

It's a great device but this issue ruins the perfection of a so cool piece of technology.

It's related for sure with environmental conditions but we cannot tell how in details it occurs.

This isn't a resistive touch screen, so no sensitive layer is present.

Knowing the characteristics of the newton rings issue I'd say that the issue is triggered by the lcd layer touching the capacitive layer.

Regards

I've now got this problem as well. Tried the fridge method, which does work but comes back again not long after. I bought mine in the states though but live on Europe. Does anyone else who imported it think that once its released widespread here that we will be able to get away with using the warranty to return it? Sending it back to the US of A is just too much of a hassle.
[Galaxy Tab 10.1 General] thepringlesguy:
We all understand that this isnt actually moisture right? Its the LCD touching the glass.
[Galaxy Tab 10.1 General] pakerfeldt:
Has anyone sent their device for repair and got it returned yet? Last friday (July 22nd) I did send my device for repair. Still have to wait at least another 7 days for it to be returned I guess. Curious to see if they actually manage to repair it or not.
[Galaxy Tab 10.1 General] Drakknar:
Samsung Italy support told me that they'll take care of my I/O tab in Italy with the standard 24 months warranty. It will just go into a different process for repair which will take about 15/20 working days (or, at least, that's what they say)
[Galaxy Tab 10.1 General] hotleadsingerguy:
Same thing though.

They *are* Newton Rings. Basically it's just a refraction of light because the panels aren't lined up perfectly. It doesn't affect anything, it won't hurt anything (won't destroy your screen or your Tab), and it shouldn't ever really get worse (unless you drop it or misalign the panels even more...hard to do). Basically it's just a visual annoyance that's hard to get around.

The iPad2 gets around it by making *extremely* rigid gorilla glass. I know it doesn't seem that way because there are videos of it bending like crazy...but relative to the glass used in the Galaxy Tab it's incredibly rigid.
[Galaxy Tab 10.1 General] .torrented:
so merely a cosmetic design flaw... i figured it was just the two screens touching in the center... like back in the day when everyone used to press on old calc. screens to make them change colors (oh what fun it was)
[Galaxy Tab 10.1 General] kauka187:
I hope this will be the same in France. Otherwise I might send it to Italy lol. If you could keep us updated with what happens that would be awesome. Cheers
[Galaxy Tab 10.1 General] Drakknar:
I'll keep you updated, but it will take a while. Collection centers are not sending anymore stuff to Samsung repair center until the 28th of August, so I'll have to wait till that time :(

I'm just wondering if there's any way to manually fix the problem as somebody over the internet have already disassembled the tab...
[Galaxy Tab 10.1 General] kauka187:
Just an update. I've used the fridge method before, and it has worked, but then the problem has come back as I've mentioned before. However today I put it in the fridge again (cos some mates were coming round and I wanted to show off the tablet lol), went and did some errands (about 15 mins) and then when I came back and took it out I noticed it was nearly out of battery so I put it straight on charge. Its been 10hrs since and the "moisture" hasn't come back.

Admittedly its still been plugged in but I'm using it and so far so good.
[Galaxy Tab 10.1 General] tenderidol:
I don't think putting electronics at 4 C and taking them back to room temp suddenly and charging batteries is such a good idea. Condensation may occur due to sudden temperature changes and hurt the tablet even further. You guys should find something safer than the "fridge method" :D
[Galaxy Tab 10.1 General] paalkr:
I had the same issue on on 32 gb gray device, LCD crystals were "floating" in a small spot at the screen center. Returned that one, and got a replace device with a 7cm hair between the glass protection layer and the LCD panel. The second replacement device was ok though.

Does samsung have a general build issue, or is it only the galaxy tab that suffers from a high percentage of faulty devices?
[Galaxy Tab 10.1 General] thepringlesguy:
I would stop putting your tab in the fridge.
[Galaxy Tab 10.1 General] kauka187:
It worked though. No more newton rings. Been using it off charge as well and it still hasn't returned.
[Galaxy Tab 10.1 General] tenderidol:
In that case, try the opposite and put it in a hot environment for 15 minutes or so and see if it comes back or not.
[Galaxy Tab 10.1 General] kauka187:
Tell me genius, why would I want to do that?
[Galaxy Tab 10.1 General] Giia:
I have a Samsung TV, blu-ray player, epic 4g and now the Gt10.1. The build quality issuse is unique to the GT10.1. The epic is extraordinarily sturdy. Mine skidded under a bus..not a scratch.. works perfectly.. keyboard sliding as perfect as the day I bought it. My TV and blu-ray player are same as the day I bought then... yet this is my third GTAB. The previous Units had the same issue... Bestbuy tried the "its just the LCD technology " line on me when I returned this the last one... they even suggested that I was damning it from the pressure caused by putting it against my back in my backpack... when I explained that it is always in the leathter case I purchased with it... they then said that perhaps the case is the cause but that its due to too much pressure...I looked at him and said... its a touch screen... if one cannot apply pressure to it then this is worse than a defect, its a design flaw... he walked off to get me a replacement. The GTab rep from Sammy happened to be in the store trying to talk with them about why customers are returning it..... they would not let me speak to him :-$

If Sammy had launched with TWiz, chose Thumb Keyboard instead of Swype and not have the heat/LCD issues... this could have been the defacto standard for HC 3.0+ tablets. Instead they rushed to market to beat the launch of ipad2...

They have repeated the exact mistake Palm made with the PalmPre.... rushed to market.. app support and build quality issues....

The sales rep was right about the backpack.. but not the cause... putting it in my backpack is the cause because I ride a sportsbike in the Florida sun :) its the heat... not the pressure... but in Florida there is no solution to that... not for another 3months
[Galaxy Tab 10.1 General] Shadowguy:
Technically the besbuy rep was correct...take a read through these post. It is the phenom call "Newton Rings" annoying yes....screen damaging NO.

The Galaxy Tab has an amazing build quality even with my case of newton rings i still pick it up 9-1000 times per day love the device.

EDIT: POINT PROVED I WAS OUT OF LINE CONTINUE ON!

http://en.wikipedia.org/wiki/Newton's_rings
[Galaxy Tab 10.1 General] Phil_Glisson:
FWIW (see my prior posts in this thread for more info), I have NOT seen the newton rings return since my curious encounter sitting outside of a café. It has traveled over 1,000 miles with me, has been through a variety of temperatures, and has been used casually (~1-4 hrs / day). I'm currently staying in FL and plan to use it outside tomorrow. Here's to hoping I'm not jinxing myself.

Brief Recap: Did NOT use refrigerator method. Instead, I gently manipulated the device, observing the behavior of the rings, until I found the right amount of pressure in the right areas that made them disappear (NB: If you try this, know that I NEVER used much pressure to effect my results). I remained outside in the hot weather while I did this too. Unless both (1) they do not return for me and (2) someone else replicates this, it can only be considered a stroke of good luck, chance, a random event, and what have you in the mean time.
[Galaxy Tab 10.1 General] tenderidol:
Because, putting a tablet in a fridge is not natural, whereas many people use their tablets under hot and humid conditions, Einstein. Besides, it may show you that you still have the same issue, just hasn't found the right conditions to uncover it yet. Then again, good luck with your chill cycles.

Close this thread? Really? It's been very informative for me when deciding which tablet to purchase and it will determine my future purchase (i.e., Samsung GT8.9). I'll continously monitor this thread to see if the problem is solved and how Samsung is dealing with it before I buy my next tablet. Therefore, please keep this thread OPEN to help everyone.

Just because you now know what the defect is called doesn't change anything. In addition, many people who are faced with this issue will not call it "Oh darn, I got some Newton's rings on my tablet", hence the title of this thread. Yes, it's not moisture, but that's how a lot of people will describe it until/if they Google it.

I am following this thread for two things: 1. How the units that were sent to Samsung came back, and 2. How the new units are in parts of the world where the launch was delayed due to this issue.

Thanks for everyone who took the time to post in this thread for current and future GT users.
[Galaxy Tab 10.1 General] lhutfhy:
I have Samsung Galaxy Tab 10.1 with 3G version.

got this LCD moisture defect (a huge one, like the size of blackberry gemini type).

somehow after using it for about 3 weeks, the moisture is gone by it self.

try to push the screen to see whether the moisture will show up again or not, but strangely the hand push don't produce any glitch or an effect like any LCD screen, no moisture?? no anything.

btw, it seems this change happen since I put book case to my tab.

I am already in the queue for a replacement, but with current condition, i think i will keep my tab.
[Galaxy Tab 10.1 General] kirdroid:
Anyone sent the tab to samsung support or spoke to them about this issue? I'm planning to call them, but sure they will ask me to send this and wait 2-3 weeks for fixing or taking a look at it :(
[Galaxy Tab 10.1 General] pakerfeldt:
Can someone, living in US, post to @Samsungservice or @GalaxySsupport and ask about this? I tried to but they would not answer my question as I'm living in Europe.

Gosh, I'm not allowed to post external links yet. So here's an un-clickable link to my tweet: twitter.com/#!/GalaxySsupport/status/96692329221599232
[Galaxy Tab 10.1 General] kirdroid:
I don't think you are going to get any official response from them on twitter. That is the last thing they would want to do.
[Galaxy Tab 10.1 General] pakerfeldt:
Not even worth a try? At least we would push for some answers, in public.
[Galaxy Tab 10.1 General] hnakhi:
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!! i am days away from buying the galaxy tab and now i find this !!!

i live in kuwait and it is very very hot

the lowest temp we get is probably 35+ and that is during night !
[Galaxy Tab 10.1 General] kauka187:
I don't know about you, but when I fix something I don't go back and try and break it again for ****s and giggles. Especially when its a $600 tablet. You know, just saying.

But its been 2 days and it still hasn't come back. Maybe after the fridge method separated the layers,the electrical charge from the charger fixed the alignment. Who knows, I'm just glad I don't have it anymore and its perhaps something others can try if they so wish.
[Galaxy Tab 10.1 General] duraeas:
There is a very little space between the LCD screen and the glass on these tablets, which is why they're so thin. The splotch isn't caused by moisture, it's the screen pressing up against the glass.

It happens more in the heat because Lithium batteries expand slightly when they're warm. On mine it happens when the tablet is left face down because the batteries are pushing lightly on the screen. Some are going to be better than others due to fractions of a millimeter in variation between the devices. I don't really care about it, I don't notice it when it's on and it goes away when I'm actually using it.
[Galaxy Tab 10.1 General] :
The fridge solution won't solve it definitely. It will return when the right conditions are matched. By the way, I've done slot to put this thread to the web attention. I tweeted samsung and they thanked me for the info. I sent them the link to this thread. So they already know about this issue for sure. Many web sites are talking about this issue now.

Please keep this thread open so we can refer to it when needed.

Thank you all for your support.

Regards,

Daemon

Got mine back in exactly one week time (monday to monday).

According to the repair document, they replaced the screen and flashed the firmware (no clue why, useless anyway as i already flashed original image with ODIN before returning the device).

Anyway, screen is new for sure (came with original screen protector on it) and the problem has - of course - gone.
[Galaxy Tab 10.1 General] kirdroid:
Cool man thanks .... calling them right away.
[Galaxy Tab 10.1 General] kirdroid:
Called Samsung Support, opened ticket and sent for repair. But it is UPS ground so will take quite a while to reach, repair and me getting back :(
[Galaxy Tab 10.1 General] tenderidol:
Good luck with your repairs.

When you called, were they aware of the problem, or did you have to explain everything?
[Galaxy Tab 10.1 General] kirdroid:
Just called them and told about the moisture problem. Rep put me on hold for some 5mts to check something and told that I need to ship it to them to take a look at it.

Mine was there from the last 4 days and even when I shipped today, so they should see it if it doesn't disappear.
[Galaxy Tab 10.1 General] .torrented:
Sounds like they are putting new (different) screens in them... I'm gonna wait another week or two before I go buy one... Where are most of you buying them from anyways?
[Galaxy Tab 10.1 General] tenderidol:
Don't worry, it's not going to disappear, if it is being transported by UPS ground. The back of those trucks are 100+ degrees :D
[Galaxy Tab 10.1 General] beachbum13:
Called Samsung support this morning. Agent asked if I had dropped the unit or applied pressure to the area. After more questions, he said he'd get back to me... He called me back 20 minutes later after 'discussing' this with his colleagues and said that they are aware of the problem. They sent me shipping info. Will send it out tomorrow after I attend the NYC Samsung event.
[Galaxy Tab 10.1 General] pakerfeldt:
Got an answer from Anovo (the company repairing Samsung devices in Sweden) and they told me: "Din enhet väntar del. Displaymodulen kommer att bytas ut." which pretty much means "Your device is awaiting a spare part. The display module will be replaced."
[Galaxy Tab 10.1 General] dmcman73:
Here is my thought on this since it just happened to me while i was outside with it for a bit.

It seems that they issue is one of two things:

1. There is a vacuum effect going on. When the device heats up a vacuum is created between the digitizer and the lcd screen causing them to touch which in turn causes this "oil mark". The fact that it is happening in the middle, where there is no support, is a strong indication that this is happening.

2. There is something internally that is expanding due to the heat causing the lcd to be pushed outwards causing the two screens to touch. I doubt this is the cause but still could be a possibility.

I am confident that it is a vacuum that is being created between the two screens that is causing this. If so, this can be corrected. The Tab can be taken apart and using a small needle like a sewing needle, pierce some holes in the glue or double back tape that joins the digitizer and LCD together. This would allow air to come in and eliminate the vacuum. The smaller the holes, the less chance any type of dust will get in there.
[Galaxy Tab 10.1 General] tenderidol:
Great news! This gives me more hope for my planned purchase of the GT8.9.

Or, you can just send it to Samsung and have them replace the screen with a problem-free one ;)
[Galaxy Tab 10.1 General] Phil_Glisson:
Where, precisely, is the battery? Is it in the middle of the device? If not, what is? It might even be something around the middle of the device that, when it expands, it causes the area in the middle to develop the newton rings. This would explain what happened to me rather well. When I pushed on the middle of the device in the back, it caused the rings to slowly disappear, starting from the outermost edges and finishing in the middle. One way this would happen is if, by pressing the back of the device, it caused the middle of the screen to touch even more and thus relieved pressure from the outer-middle. Once I let my hand go, it pulled away from the LCD screen, which is why the precise middle was the last to go. This sounds terribly confusing and I apologize. There are too many pronouns and whatnot. I hope someone understands. I prefer diagrams and wish I could draw one to use as an explanatory tool.

Well...I decided to give it a try anyway. I know this is going to look ridiculous, but bear with me.

With pressure applied to the back, the area of expansion now shifts to the center of the device, relieving pressure from the original area of expansion. When external source of pressure is released from the back, the center where the last of the Newton rings are begins to return to normal as the device returns to its ideal shape.

Perhaps those whose problems are more permanent have devices that are more abnormally shaped than others, lending credence to the Warped Theory? This also explains why the Fridge Method works.
[Galaxy Tab 10.1 General] x616e74:
Mine arrived today and after un-boxing I went to plug it in and noticed that a very large set of rings had appeared in the center. It appears that the pressure is very variable by picking the device up at only one corner indicating that there is no support though the back and the device actually warps easily. I believe this would not be a problem on certain other tablets with a more "unibody" design and made of aluminium or another metal, but this tablet being incredibly thin and plastic seems that there is no support in the middle so the screen actually moves closer and touches.

Interestingly enough I received the package and one of the seals was already broken, and the other one replaced so it looked it had already been returned once and in the bottom of the box was a "screen faulty" sticker.
[Galaxy Tab 10.1 General] x616e74:
Called PC World (in the UK) customer service and they reserved a replacement for me in the nearest store, went to collect and now have my repalcement, less than a few hours!

Congrats to them for such a quick response.
[Galaxy Tab 10.1 General] tenderidol:
Wow! :eek:

Where did you buy it? Not only they shipped you a used/returned item, they sent it with a "screen faulty" sticker!

I hope you'll get your replacement -hopefully with no stickers and defects- soon.
[Galaxy Tab 10.1 General] reprod:
I haven't had any screen issues and I have been using my Tab on a daily basis. One thing to note is that I do use the Samsung Bookcase Cover which possibly takes away some of the pressure from the chassis of the device.
[Galaxy Tab 10.1 General] Maxipad10.1:
Im kinda scared now to bring my GT10 out side. I took it in the car i noticed the samsung case steamed up all sick from the humidity in Florida. scared to take it out back to read and back in the AC. Don't need mine to WARP. I havnt had a problem with the screen at all. Im thinking only a SMALL number of people have had screen problems. Am I just being paranoid?
[Galaxy Tab 10.1 General] Handsome(OD):
HI guys, mine p7510 was bought in USA, now im in Ukraine ,where i live and have the same problem with Moisture under screen. I have no box from tablet, but have a warranty ticket? what should i do? Should i contact samsung support in USA and send it via fedex, so they can replace screen??
[Galaxy Tab 10.1 General] flo7002:
I bought mine a couple weeks ago at Staples. I noticed the issue when I took it outside one day. It went away pretty quick when I went back inside and haven't had any problems. It seems to just be a problem outside in the heat and moisture...
[Galaxy Tab 10.1 General] kritonas:
that happens to me when the tab is under pressure (ie in a bag, with lots of other stuff). It goes away after a few minutes, perhaps more, up to a couple of hours. It used to happen to my o2 xda2 as well, when i put it in my pocket and the jeans were tight.

Bottomline: from my experience that's due to pressure being applied to the screen and it'll go away after a while. if it doesn't, it's probably something else.
[Galaxy Tab 10.1 General] Jardicel:
I have seen this only once, and it was only when I gripped the tablet too firmly.

If everybody with a Galaxy Tab 10.1 has the issue, this thread would be attract much more attention, and there would be much more talk about it. So with this in mind, I think that many people AREN'T having the problem, while some people like us are.
[Galaxy Tab 10.1 General] kauka187:
Nah I would wait till its out everywhere in Europe (though that might be hard now with apple's new injunction) and then try to organise a replacement with Samsung Europe. They may honour your warranty.

You could try Samsung in the Netherlands as the injunction against Sammy isn't recognised there. Let us know if you do as a few of us have imported as well and it could prove useful.

Cheers
[Galaxy Tab 10.1 General] Kayak83:
Has it been decided that this is causing damage to the screen? Mine only does it outside when the sun is on it and it gets hot. I'm not too worried about it but will gladly get it replaced if that's the case.
[Galaxy Tab 10.1 General] kirdroid:
Getting back my tab from samsung service center today...will update in couple of days if I see the moisture back or if see any difference.

Edit: Called them to ask what repair they performed. They said the LCD has been replaced. I assume it will not be a problem from now but only time will tell :)
[Galaxy Tab 10.1 General] cypherx82:
Got my Grey LTE Tab yesterday. No issues from what I can tell.
