[Galaxy Tab 10.1 General] Husker Kurt:
I had the same issue described and shown in a few pictures. Didn't show up at first, and then the third day of owning it (bought it on the 17th at Best Buy), we had been out and about and had taken the Tab with us, and asked my wife to get it out so I could use it, and saw this same thing on the screen.

When I first saw it, I thought it was just a smudge or something, but noticed when I tried to wipe it off, not only did it not disappear, but it kinda moved around, and decided it must have been something with the glass contacting a portion of the screen itself or something. It wasn't very noticable with the screen on and looking directly at it, but it was noticable from an angle, and also on anything with a white background, you could make out the distortion. I tried pushing at the edges of the glass and could get the spot to become smaller, but not completely go away. Even though the problem may have resolved itself, we decided to go ahead and take it in to Best Buy and exchange it.

I didn't go so I didn't get to talk to the people at Best Buy, but apparently the person there told my wife that it was some sort of pressure damage, and normally they wouldn't replace it, but he would do it this time, because he believed us that we didn't do anything to cause it. He then used the opportunity to try and sell my wife on a replacement plan. Anyway, haven't had any issues with this one yet, and hope it stays that way.

I could have lived with it...maybe. But for $600, I think it should be flawless.
[Galaxy Tab 10.1 General] nakuma:
Tweeting GalaxySsupport to see what they have to say. My first white 16Gb had bad light bleed. Exchanged for Grey 16Gb and got this "moisture"/"oil slick" problem. Exchanged for second Grey 16Gb and same issue. Hoping to get quick response from Support. Don't want to have to return and wait for something else to come out. :(
[Galaxy Tab 10.1 General] Kitinas:
I have an I/O Tab and noticed this the first day too, right out of the box. A small inch-ish sized spot right in the middle of the screen. It went away after being used for a little bit, though. It came back randomly over the next couple days, but I haven't seen it back in a few weeks, so it seems to have solved itself.
[Galaxy Tab 10.1 General] wesbalmer:
I updated the OP with a picture. This is a defective product, and we who have the issue need to send a message to Samsung by returning them as defective products.
[Galaxy Tab 10.1 General] kirdroid:
Thank god I found this thread. I had a gray 16gb tab from frys which was flawless, but I was waiting for white one to arrive in my local bb. So yesterday I got the white one and noticed this moisture right in the middle of the screen. I thought of exchanging it but the moisture was gone after some 3hrs. I will probably go back and try to exchange just to be safe.
[Galaxy Tab 10.1 General] wesbalmer:
It goes and comes back, I took that picture less than an hour ago and its already gone from my screen...... I'm starting to think its reliant upon temperature. However, I don't want to stick it in the freezer to test..... Maybe someone living in a colder climate than Los Angeles, CA can chime in???
[Galaxy Tab 10.1 General] Rhyno77:
Totally reliant on temperature as far as I can tell. My daughter gave my tablet of a big squeeze while playing "cut the rope" and I had a 3.5 x 1" mess in the middle of the screen. 30 minutes later it was gone. Then after putting it in the dock for an hour (next to a window with the 112 degree Phoenix sun outside) and the oil slick was back in full force.

To test your theory I put it in the refrigerator for about 10 minutes well monitoring it, and the effect shrunk down to nothing. Nothing since then, but we'll see what happens tomorrow.. :-)
[Galaxy Tab 10.1 General] ericc191:
Exchange that right away. Mine would show signs when pressing on the screen but go away very quickly. I used it in the car earlier around 90 degree temps and no oil looking stuff on the screen showed.
[Galaxy Tab 10.1 General] jackie_jagger:
Guys is it any particular set/batch of tabs that seem to have this or the ones from a specific retailer !! is there any consistency in any of this?
[Galaxy Tab 10.1 General] quattr0:
I'm returning mine after 1 week. The screen color is bleeding. I was watching the voice Back and forth then bam, the color is gone! Try to watch hd flash back and forth and see if it will happen to yours

Ive been a Samsung fan all my life. This is sad. They start to be like LG now. Life is NOT good!
[Galaxy Tab 10.1 General] Canadoc:
Not a gtab user bit think I understand the problem. I have aclear iPhone 4 case. When on it creates the same type of oil blob appearance on the back. There is no moisture. It is simply the interface of the contact point of the 2 surfaces causing this rainbow oil boob appearance on the tab. In all likelihood the gtab has the LCD and glass layer very close together due to the thinness.

As a result at times there might be slight contact between the 2 causing this effect.

Temperature may have an effect as things generally expand a tiny bit with heat and may explain why it goes away when not used.

I read that the TF has glass further away which as a negative induces more reflection. So this appears to be inherent in gtab in design and returning might be a similar gamble to the light bleeding issue on the Asus TF
[Galaxy Tab 10.1 General] dulaney22:
Bought one Thursday and took it back yesterday. Replacement has been fine until 30 minutes or so ago. Is this to be expected from such a thin design?
[Galaxy Tab 10.1 General] Canadoc:
I suspect heat and applying pressure make it happen.
[Galaxy Tab 10.1 General] dulaney22:
Heat may be an issue since it's summer in the south. However, neither unit has received excessive pressure.
[Galaxy Tab 10.1 General] wesbalmer:
I can't imagine heat causing this. If the issue is with two surfaces touching each other than heat should create positive pressure between the lcd and digitizer, creating an even larger cavity between the surfaces.
[Galaxy Tab 10.1 General] SenatorKen:
I finally returned mine for replacement. Had trouble reproducing the problem, so ittooka couple of trips to Best Buy. I init. thought it was pressure caused, but eventually found my oil slick appeared after placing the Tab face (screen side) down for a few mins. Glad i exchanged it. No issues with the replacement yet (fingers crossed).
[Galaxy Tab 10.1 General] slack04:
Just going to throw it into this thread that I don't have this problem, nor does any galaxy tab I've ever seen (outside this thread). Not saying it doesn't happen, just pointing out to people who are scared away from the GT10 by the few who have had a bad experience...
[Galaxy Tab 10.1 General] Bauxite:
I put it back in the box it came in, they returned it in the same box.
[Galaxy Tab 10.1 General] lama16:
I also sent mine to A Nova in Norwich. They dont have a clue how to fix it! Plus they might someone mention that they dont have the equipment to repair it (MPI they called it). They had my tab since 18th August! They mention about being in contact with Samsung to find a solution how to fix! No sure when I will see my tab again.
[Galaxy Tab 10.1 General] markdj57:
No point in searching for ipad newton rings as no ipad user would describe the issue as such or know what newtons rings were :-)

There are lots of posts about the yellowing issue which is a similar problem with the screen construction.
[Galaxy Tab 10.1 General] Specter_Phi:
Still has newton ring issue

unfortunately, my replaced SGT 10.1 has newton rings issue still. I just put it in my bag, just the tab alone inside the bag, when i pull it out, poof... Newton rings appeared.

Im starting to love this device as i love customizing on it.

When will samsung address this issue.. Im refunding mine for the moment.

Im sad had to say bye for this tab not until they fixed the issue..... I guess....
[Galaxy Tab 10.1 General] cute_drew:
Hi am form the philippines,

samsung recently released the 10.1 here, (about 2 weeks ago). Am now on my second unit and the newton rings appear occasionally ( when am using the tablet and when it gets warm)..

Am thinking of getting a refung for this.. :(
[Galaxy Tab 10.1 General] Specter_Phi:
Yeah bro, im from manila, me too, on my 2nd unit also, im sure this is still from the first batch of supply for our country, i think for now, i have to refund too, not until samsung has resolved the issue.
[Galaxy Tab 10.1 General] ricksakuma:
In my opinion I would just return they couldn't repair mine (no parts available)In the us and the RIngs appeared after 10 days of normal use. Sending me a replacment and i will sell asap.Its a defect that is taking a long time to resolve who knows what it will look like months from now....
[Galaxy Tab 10.1 General] ronalgps:
only 7 days without my tab and im coming crazy to my tab is back
[Galaxy Tab 10.1 General] slamorte:
Where do I complain?

I sent my tab back for this issue. Samsung issued me a new one, but when I got it, turned out they sent me a 16GB when I sent them a 32GB!

After a half-hour on the phone, "Executive Customer Relations" acknowledged that they made a mistake, but refused to overnight me a 32 GB until I sent them their mistake back. When I asked to speak to the guy's supervisor, he told me he was the supervisor for ECR for the entire United States and directed me to send my complaints to "the president". He gave me an email address for "the president" - when I sent a message, I got a delivery failure notice returned.

It's now over three weeks since I sent in my Tab (from NY to Texas).

Anyone know a reliable phone number/address/email address where I can complain?

Thanks
[Galaxy Tab 10.1 General] TECK:
I don't think is worth the trouble to complain. They will definitely not give you a free tablet or do anything special. :)

Just swallow it and send them back the unit. Or you can call Samsung at 1-800-726-7864 and request a courtesy call. You will end-up talking to someone nice who will still do NOTHING for you, beside apologizing... which is worth nothing. It will only get you more irate and nervous.
[Galaxy Tab 10.1 General] Nucking Futs!:
Are you guys/gals getting the NR's no later than roughly a few weeks after purchase? I've had my SGT 10.1-4G for a little over a month yet no probs however, reading this thread is concerning. FWIW, the only time it gets turned off is when I restart it every so often (3 - 4 times since day 1).
[Galaxy Tab 10.1 General] tbcpn:
Consider yourself fortunate. My brand new

replacement from my local corporate VZW store developed NR four days after I got it. So far they're going away but getting worse. And yeah, I'm very careful with my electronics -- no a screensavers, no scratches, zero abuse. May return this one. Aside from this, I really like the Tab compared to my XOOM.
[Galaxy Tab 10.1 General] mroneeyedboh:
Is this issue across the board? Or is it mainly effecting the verizon tabs? And it seems that if you haven't gotten it yet, you will....right?

Sent from a miui powered HTC Evo.
[Galaxy Tab 10.1 General] TECK:
I have my P7510 for over a week and no issues what so ever with the screen. I use a vanilla 3.1 Honeycomb ROM with CWM 4.0.0.4 and no TouchWiz crap installed except the 11mb update to get Google Movies installed. I had a locked nvflash on my tablet, so it did not matter to me. So far, I abused the tablet while on vacation... in average 10hrs daily usage to watch Netflix movies, browse, email, etc.

I never had to restart the tablet, like you mentioned above. When this occurs to you?
[Galaxy Tab 10.1 General] shuttlexp:
I'm from the Philippines as well.

I got my Samsung galaxy tab 10.1 at Greenbelt-5 pre-launch(Aug21).

The 1st unit was SIM-locked to smart and have it replaced on the second day.

Now my second unit has this newton ring issue which appeared after 1 week of normal use.

I called the Samsung service center and I was advised that this issue is normal for 10.1 since it is a very thin device.

WTF! at this price point I think it should be Perfect!

Have you brought your tabs to service center yet?
[Galaxy Tab 10.1 General] poisike:
I was afraid that they will say that at some point :(

Considering that the new Toshiba tab (announced yesterday) is about 1mm slimmer then the GT10.1, it won't have a working screen at all?
[Galaxy Tab 10.1 General] TECK:
Revert to a stock ROM, call Samsung and tell them that you get random reboots out of the blue. :)

They will send you a new unit. Simple.
[Galaxy Tab 10.1 General] TabGuy:
Mine didnt show up until I had it for 5 weeks. No it come and goes.
[Galaxy Tab 10.1 General] Specter_Phi:
The first one, i bought it to samsung setvice center, and they confirmed the NR on my screen, what they did? They offer me for a screen replacement for free but i didnt take it. What i did i return it to the store who assists me on their launching at Greenbelt 5 and replaced it. Now, on my 2nd unit, im returning it too due to the same problem.
[Galaxy Tab 10.1 General] MasterRy88:
If Samsung offers you a replacement screen I would take it. From what I've read other users who have done this reported that the screen they got seemed more rigid and did not flex as much making the newton rings less likely to appear. Someone please correct me if im wrong on this........
[Galaxy Tab 10.1 General] mroneeyedboh:
So these tabs that dont have the NR will only get them in due time right? It's like we don't see it across the board, but people in here that have it, get replacements and then get it again with in a few weeks on the new tab..

[Galaxy Tab 10.1 General] TECK:
When I got my P7510 32GB at Best Buy one week ago, the rep told me they just received a new batch the same day, they were sold out previously. For reference, my batch is GTP7510MAVB. Any of you with this batch number had screen issues? The screen looks very rigid to me, I press it fairly hard in several areas and no rings made surface.
[Galaxy Tab 10.1 General] bijixda:
Try to put in the freezer
[Galaxy Tab 10.1 General] Specter_Phi:
I just came from samsung service center at Mall of Asia, since the staff cannot give me assurance that the issue is resolved if i replace my unit for the third time, i opt for the refund option already.

i just hope that the next batch has been resolved already. its supposed to be a good gadget, its just its major screen issue that pulls it down.

its so disappointing that the front desk of the service center keeps on telling me that "ITS JUST OKAY! IT WILL NOT CAUSE ANY PROBLEM WITH YOUR UNIT" didn't they know that the presence of NR is also the contraction of the LCD and the TOUCH GLASS? that later on will cause major issue on the lcd, to mention, dead pixel, miss alignment etc due to the pressure?
[Galaxy Tab 10.1 General] bijixda:
hmmm put in the freezer, NR gone for one night. but when go outside it come back :(

any permanent fix to try? before i returned for service
[Galaxy Tab 10.1 General] tiyok:
report from singapore.

mine is US unit 16GB 3G..had this issue about a week after purchase. brought to service center in singapore, and they replaced the LCD (returned within a day).

however the "oil" appeared again after 3 days..I just brought it again to the service center..im not sure whether they really replaced the LCD last time..i will ask them to showw me the old/replaced LCD when i collect the tab tomorrow..

btw, IMO dont put the tab inside the fridge..im worry it gets condensation internally after that, and sure warranty would gone.
[Galaxy Tab 10.1 General] apolloms:
chatting with a samsung rep now about sending mine back and he replies with this:

Ian: Hi. I have a 32gb wifi tab that is constantly getting the newton ring problem that i would like to send in for a repair

Ralph: I'm sorry to hear that. I understand that there is vapor kind of thing under the tab glass . Am I right?

Ian: yes

Ian: it seems to be a known issue with the tab

Ralph: Let me know the complete model code of the tab.

Ian: GT-P7510MA

Ralph: I am sorry, as of now there are no reported issue to Samsung from customers.

Ian: thats not true, tons pop up when you google search "Samsung galaxy tab newton rings"

Ian: and samsung has been repairing them

Ralph: Yes, as the tab is under warranty, we will get the tab serviced.
[Galaxy Tab 10.1 General] Specter_Phi:
OMG, they're pretending as if nothing happens.
[Galaxy Tab 10.1 General] TECK:
In the same spot? They probably pulled a fast one...

I have a question for you guys. My screen is extremely rigid and darker than the ones shown in videos. You can hardly see the difference between the bezel area and the screen:

The picture was taken at an angle against my black monitor screen. In the lower right corner you see the color difference between the bezel and actual screen, taken against a white wall reflection. Does your screen has the same darkness, when you reflect it against a white wall?

I'm trying to determine if there are several screen types or if there is a new batch with darker screens.
[Galaxy Tab 10.1 General] tiyok:
update 4/09/11

service center called me earlier and told me I could not get it back today..since their LCD stocks are having the same problem (?)...

have to wait until new batch of LCDs arrive..
[Galaxy Tab 10.1 General] k2snowboards88:
They have a long history of being terrible in situations like this. Just look at the horrible lag and non-working gps in the galaxy s.
[Galaxy Tab 10.1 General] ic3guy:
Here's my addition to the "Newton Rings" problem.

Purchased a wifi 16 GB black model at PC World here in the UK (Model: GT-P7510). After a particularly warm day out with the unit, got the oil slick under the screen. Returned to PC World as it was within the 21 day return period. Had no problems returning it. Exchanged for a white 16 GB wifi model (Model: GT-P7510).

Both are models starting with S/N R61B.

Otherwise, have been very happy with the unit. Hopefully they won't come back.

Cheers.
[Galaxy Tab 10.1 General] sonicrhythms:
I just noticed the oil slick today in the top left side of the screen. I wonder if its worth exchanging it from Amazon since that doesn't guarantee I'll get a "good" one.
[Galaxy Tab 10.1 General] novasam:
Even happens is dry heat

The first time I noticed it, was in my A/C cooled home. I'm in southern Washington which is pretty dry. Now that temps have cooled down I havent noticed the rings anymore. I agree that it is a combination of the soft back and the temp. I also think the quality of the lcd screens is pretty much to blame. With the I/O version they were even coming unglued.

Hopefully this does not happen again for me, but if it does I'll be calling Samsung for a replacement.
[Galaxy Tab 10.1 General] leeboy22001:
My 16 GB version from currys uk developed this problem just before 3 weeks, so returned it today for a replacement, was hard work as they tried to reduce the effect by rubbing a cloth over it, but only made it a bit smaller. Now undecided whether to not open replacement and get my money back ! ?? I do like the look at the new toshiba excite !
[Galaxy Tab 10.1 General] paulmai:
Yup, I have had exactly the same denial from them.

Anybody else had blatant lies from a Samsung representative?
[Galaxy Tab 10.1 General] Pottsy:
Yes, see here.
[Galaxy Tab 10.1 General] Cpt Streamline:
Exactly the same here. Started off small and then went away to only come back bigger than ever. I called Samsung and they say it isn't a known issue but they will service it. Downside is i need this for work and they say it could be away for 15-21 days. :(
[Galaxy Tab 10.1 General] reNeglect:
16gb White WiFi Only good here haha =D theres no 32gb models in canada =C
[Galaxy Tab 10.1 General] slamorte:
Just got my third new tab last Friday. The rings came back today. I'm getting pretty peeved about the whole thing.

The fridge remedy worked for about an hour.

I've got a screen protector on it - anyone getting the rings without a screen protector?
[Galaxy Tab 10.1 General] patomas:
I have the rings and no screen protector.

I had them from the beginning, just out of the box. After a while they went away. After a long travel with tab in a case they are back and doesn't want to go away..
[Galaxy Tab 10.1 General] patomas:
Do you all put the tab in the fridge or in the cooler freezer (where you make ice)?
[Galaxy Tab 10.1 General] reycingef9:
Just wanted to give you my experience. After chatting with them for 10 minutes, they emailed me a shipping label. The rep was very helpful and courteous. They didn't deny the problem but they didn't admit it either. Either way they didn't give me any trouble. Very happy with the experience. My Tab is being shipped tomorrow. Now I hope it doesn't take very long.
[Galaxy Tab 10.1 General] nikond3s:
hm....

In my case the rings appeared after running around the gamescom for a whole day while keeping the tab in my bag. Since that day they constantly keep coming back. I use the original samsung diary cover as device protection. The main drivers I observed are pressure and heat (not only from the "outside" but also from the 3g components). Putting the tab into the fridge resolves the problem for a while. I'm able to keep it that way if I do not use the cover and leave the tablet in a cool place (something around 18 deg celsisus). I'm just curious if those problems would have appeared if samsung decided to use an aluminium back. Perhaps there are some "strain" problems between the different materials.

I'm currently using a white gtab with 3g and the serial starts with R2FB.
[Galaxy Tab 10.1 General] mapas:
It is caused by the fact that the case is bent, pushing the batteries towards the screen. try to straighten your tab by pushing down the edges. It worked for me.
[Galaxy Tab 10.1 General] slamorte:
I also use the Samsung branded book cover case, perhaps that is the culprit.

Above suffering from the rings and NOT using the case.

As many have expressed, I really do love the device - don't want to demand refund if the problem can be fixed.
[Galaxy Tab 10.1 General] Raistlin1:
I have already opened up a support ticket but I may wait a little bit before I send it in. I left my Tab upside down all night, looked at it this morning and the rings were there but then they went away fairly quickly.

I think I would rather wait a few months for either Samsung to have real fix for this or the newer models being corrected. The weather by me has also been much cooler the past few weeks and not in the 90's.

So it looks like anything can cause this; a case, skin, sitting in a car in the sun, in a backpack, etc...
[Galaxy Tab 10.1 General] jnix08:
Nearly a month since my Samsung Tab got replaced with the new screen from Samsung and no flaws yet. I use it 10-12 hours a day, in the sun, in humid conditions and as of last week, shuffling in and out of the rain and no Rings have returned.

Funny that Samsung is now denying this, when they told me that it's a known issue and that was a month ago. I strongly suggest sending it back to them if you can to get it replaced with the stronger screen.

Edit: I have also used the Belkin Slim case since I bought it, and it hasn't caused the rings to return yet, so the new screen is definitely the answer.
[Galaxy Tab 10.1 General] HeathicusF:
My Tab also has the Newton rings/oil/moisture in a spot under the glass. It's been there since I opened the box it came in last week. Tried the fridge suggestion and it went away as long as the device was cold (although I could wipe/clean the screen and could see them again). When the device warmed up, the spot was back again.

I skimmed the forum looking for an answer to this, but might have overlooked it. Does this really pose any long term problem? Really, it's not bothering me. I can only see it when the screen is off. It's not visible when the screen is on (unless I hold the Tab at an angle and look for it). It doesn't affect the touch functionality of the glass. If I just leave it and don't do anything about it... what will happen?
