[Q] OMG what is this a rub mark on my screen? - Galaxy Tab 7.7 General

I woke up today to find this rub mark on my galaxy tab 7.7, it stretches from one side of the glass to almost the other! When i rub it with a cloth it goes away, but then it comes back in about 30mins. Does anyone know how to get rid of this or do I have to return my product. Its not the screen as the picture will indicate the mark covers the top right side of the bezel.

I do not know if I am helping but is there a screen protector on your tab? If there is, it might be your screen protector's problem. Hopefully this helps.

No screen protector

Picture isn't very clear or big.
Samsung tablets have been prone to "oil slick" problems, which are a manufacturer's defect.
Example of "oil slick:" http://www.youtube.com/watch?v=orEJGB9r7OE WARNING: Loud noises on video.

When I get home from work I'll be able to snap a better picture of the mark.

Ok, here's an updated picture.
[update] again, let me reiterate: when i wipe down the marks they go away, but in time they return

Seems to be an issue with the glass (or better the manufacturing) as it also goes under the bezel. I would return it for guarantee.

try cleaning it with a mild soapy water if not have it replaced.

Yea it looks like the glass is detaching from the panel only in that area. Either the adhesive there isn't enough to hold it down or there could be a curvature in that area causing it to lift up. When you press it down the adhesive takes for a bit but eventually detaches again. Either way that's a manufacturing defect so you should definitely return it. It could eventually spread to the rest of the screen in time as it weakens the adhesive around the affected area.

yes you are right, I woke up this morning and what did I find but more lines, I called expansys.co.kr and they initially told me I would have to pay a fee for the lcd to be fixed, but since I told the rep its more a problem with the glass the rep told me she would get back to me later today about this issue.
thanks everyone for your input, I will update this thread when I get more info

If you look at a breakdown of the Tab 7.7 the battery is located on thats side. I had a problem once with my iphone that when it heated up the screen protector strated to warp with the heat. On cooldown and a wipe it would appear better.
This looks very similar to what I experienced it may be worth trying a different brand incase the glue used reacts more than normal to heat.
Also the treatment used on the screen is designed to resist fingerprints so it may also prevent the glue from adhering.
I use screen cleaner on my screen before fitting screen protectors. It may help.

[Q] Screen Separating from Chassis

Can anyone else see evidence of the screen separating from the chassis?
Mine is parting in the bottom left corner of the phone and the screen is starting to sit proud; see attached photos. As the glass is flat and I doubt it bends, the chassis/internals must have some residual stress from manufacture. It can be pushed back together but opens up again after a few seconds.
I'm awaiting advise from the seller (Elcell.co.uk)
Such damage
Screen Separating from Chassis
mine has the same problem.
I noticed that it is starting to get loose on my phone.
Also the T from the HTC brand on the back is getting loose.
I have the same on the topp
I don't have the problem (yet). I have my device only for 6 days...
same issue here
Thanks for pointing this out. I had my glass slightly lifted since i got this replacement unit. I thought it was just a slight misfit into the backcover. Now that you pointed this out, i notice the same peeling off on the bottom part of the glass. I press it down, and the phone got a solid feel.
Although it lifts up again after a while. The adhesive is not so strong.

[Q] Screen Defect?

There is a a horizontal line just below the top of the screen which annoys me a lot. From the center to the left edge. First I thought it was a smear. I tried everything, cleaned, sprayed Iclean, but it is still there. I slightly remember that I peeled something from the surface on my first use thinking that it was a sticky thing, something like a tiny piece of glue. Could it be that I peeled its coating? If so, how can that be that easy? Isnt this made of unscratchable gorilla glass? The rest of the screen is perfect... just that, and you only see it when the screen is off. It kinda goes when you wipe it, then back there in a second. Any ideas? Is this a screen defect?
If you're still within 14 or 30 days (depends which provider you're dealing it), return/exchange it.
If you pass the date, call Samsung. They will repair for nil if it's hardware issue.

[Q] Weird S4 screen issue - any ideas (?)

Hello everyone. I've been using my S4 for quite some time now, almost a year. I always kept in its protective case and had a screen protector from day one. Never dropped it. Virtually no scratches on the screen protector. A few days ago I noticed something that looked a bit like cracks. I'm attaching some images, here's how I can describe them:
they're underneath the glass
there are no markings, scratches or anything on the surface of the glass or the screen protector in that area
the sensitivity of the digitizer has not been affected, nor has the display itself
they are advancing very slowly, the first day I noticed them the smaller ones were barely visible
they almost look like air pockets in the glue that keeps the display and digitizer together (?), cracks are not that wide i think
never buying a Samsung phone again
Is this a common/known issue ? I've seen and used tons of smart gadgets, but this is the first time I've encountered such issue.
Thank you
this is really interesting

yeah thats the adhesive between screen and the glass peeling off..
Not sure what to do here. I could try to _gently_ apply some heat (via a hair dryer), but I think I rather send it to an authorized service. It's still under warranty and it's not my fault so they should fix it for free. It's not that much of an issue now, but it will kill it's resell value later. One thing to learn out of all this : Samsung - never again. Sony and LG look so much better now.
Voting for a 1.april fools joke. Seems like you've just scratched the top layer film. The clue is where
the scratch ends that has accumulated plastic (white dot)
Sorry to O.P if I'm wrong!
Once I'll get home, I'll try to snap a picture with the screen protector raised. I don't want to remove it because it was a pain installing it. It is underneath the protective glass, I didn't even give it a thought that today was April 1st.

Ok, that's the best I could, it's not really confortable holding the camera while I lift the screen protector while I try to keep it in focus. These screen protectors tend to build a lot of moisture underneath them, never expected that. Anyway, you can probably see, the problem is not a scratch on the screen protector.
My bad, proof enough! I feel sorry for you, never seen that one before.
If you now you haven't done anything wrong the blame is on Samsung. Maybe you should go with your initial thought about sending it in under warranty.
Itcould be they have seen cases like this and know about the problem. Fixing yourself seems risky. There are guides
changing the touchscreenglass on youtube.
Good luck, wathewer you choose to do! Please report back to this thread if its get fixed or not.

Stained screen? Smudged screen? I dont know...

Hey guys.
So yestreday I was using my phone with a light in the room. And I decided (since i now have the s7edge for about 3 weeks) to check unde4 light if there already are any microscratches
... and there are some although I take care of my phone like its a newborn baby. But its also only visible under light. So, the microscratches didnt really bother me... i noticed something else. Its like a stain or a smudge on the edge of the screen, on both edges actually... left and right... and they are not even the same, they are not symmetrical. At first i thought its just dirty but after rubbing it, it didn't go away.
So what I did was, I washed it under water (mind you, this was THE FIRST time I got my s7e under water).
I cleaned it good,wiped it good. But it is still there.
Then I went to google about this and found nothing... all i found, worth checking was some guy who said he had a gap between the FRAME and the SCREEN, and that he had sent it back to get that fixed (and it took samsung like 3 times to send him a good phone). So i checked that video and some people in the comments were reporting that the gap between screen and frame is so big that they can put a piece of paper under there. I of course tried it myself out of curiosity and ny phone also has the GAP between screen and frame. And after i washed it yestrday.... i noticed some water in between the edge and screen... inside that gap.
Now guys tell me those anyone else have that smudge or stain? Does anyone know what it is? (Remember it was there before I even got the phone wet for the first time)
And tell me does anyone else have the gap between screen and frame? And did anyone else notice a little water between screen and frame in that gap? Does it mean its not water and dust proof? I must say that I got it wet pretty good under tap water, but it is still working perfectly... i am just afraid now that there is a ways the water will get into that gap someday and ruin the phone. I really hope this is normal and its just how the phone is built and it is till waterproof and dust proof... but i water can get into that gap i do not know how it can be dust/water proof....
Thank you for all the help guys!
Oh and here are the pictures of the screen smudge/stain. I only took pictures of the left side of the phone screen. 4 pictures. 2 are original, other 2 have a marking so you can easily spot what we are looking at.
And you can maybe try to the gap between frame and screen,but i am not sure it will be possible,as i took that picture to show you the smudge,stain and not the gap.
Also I must say that this smudges are on both sides of the screen visible ONLY when the screen is turned of, or if you have a black wallpaper and if you dont pay attention to it you can hardly even notice it, even with black screen or turned of screen. Its the easiest to see under strong light.
is that the same place for the gap between the edge of the screen or thats for the cover section at the back of the phone.....
also ste you using a screen protector or that stain is directly on or inside your actual screen did u use a screen protector before or not at all
Hi there,
The gap between the screen and the frame is normal. Every phone has it, and I have it also, was multiple times in a swimming pool with the phone and it still works. About the smudge, I do not know, it seems like the oleophobic coating of your screen is weared off. Maybe send it back if it bothers you much?

Hi, I had the same problem, a while ago, with a Sony device. I thought it is water in the first, but I send it to Sony to be save, and they replaced the screen. It was a part of the screen, it peels off, and sticked on the screen-glass.
Nah its not really bothering me... but i dont know what it is and i got scared a little. Like i said it not really visible unles you tilt the phone and turn it under a light or sun.
I dont know how could the oleophobic coat wear off because the phone is 3 weeks old. Bought it three weeks ago, tottally new.
I dont use screen protector but i do have a spigen case.
So I guess its what Pufnasti said. The screen peeled off and stuck to the outer glass...
Pfunasti, should I send it back so they repair it?

I used my brand new Sony deVice only 2 days, and I get this problem. I would say, you should send it to Samsung. It's definitely a hardware problem, and it wasn't caused by you.

If you got the S7 Edge then this seller on ALi has the proper glass for your phone as well. In any case I have seen enough videos of how to apply this protector that I am now persuaded that this is indeed the ultimate screen protector for edge phones, the only thing that is to be found out, would be the quality of the glass it self.. AKA, oleopathic coating, strength and etc. These things are important as these days 90% of Chinese tempered glass has no oleopathic coating and is not even real tempered glass, it is just a cheap gimmic that breaks easy as F***. So hopefully since this whole UV glue is a next level kinda thing, the quality might still be on the high.
When mine arrives I will make a video of the installation and post it here for you guys with my comments.
i have S9 and S7.
ok, i will wait for it, thank you Mate!

So the glass i ordered arrived yesterday. Photos below. On the 1st glance, the glass appears to be of rather good quality and it seems to have a real oleopathic coating against fingerprints, which is quite rare these days with Chinese tempered glass.
As promissed i will make a video of how i apply it and post it here.

I ordered this for my S9 plus. It worked very well. It doesn't come with an install kit to balance the dispersement of the liquid, so when I installed it I missed a small edge and I installed it a little to low on the phone so my case would move it. So I removed it.
However I would recommend this product as a good alternative to the more expensive model.
Ok so LONG post, but absolutely necessary to read if you consider using this type of screen protection. My glass arrived 2 days ago and I applied it today. It is crystal clear and the visibility is at its best, touch sensitivity has not been affected at all. It is pleasant to the touch and does not feel like crappy tempered glass. (pics attached)
I had promised that I will upload a video but I did not think it trough and on the 8th minute the memory on my backup camera finished, so without my realization it turned off.
Below however are a few notes that are important and I realized it while shaking above the phone and overcoming them
1. Make sure to put a dust sticker on the TOP speaker in case some glue decides to enter there..
2. Put dust stickers above the buttons, all of them, so in case some glue leaks out it will not go inside the buttons.
3. From the place i ordered on Aliexpress, the glue that arrived may have been about 10%- 15% more than necessary in the tube, so i got leaks on the sides of the phone once the glue spread all over, I cleaned it with a napkin, it is possible that it leaked as I may have mistakenly applied a slight pressure on the glass while I placed it. I recommend that once you release all the glue from the black non-transparent bottle, you can squeeze it and then suck up about 10 15% of the glue that is on top of your screen.
4. Make sure before you start the whole procedure, to turn your phone off.
5. Do it on a FLAT surface because the glue may start moving from the middle of the phone towards the sides.
6. If you order from the same seller I did, your lamp would likely have a pre-set timer, as mine apparently does. In this case, the lamp will turn off every 45 seconds approx, that signals that you should move it on the next area (Bottom, middle, top) of the screen.
7. I would recommend that once you place the glass on top of the glue and let it spread, DO NOT freak out if it leaks. Turn on the lamp, and move it on top of the screen from top to bottom for about 40 seconds so the glue hardens just a little. Then with a napkin gently absorb the leaked glue.
8. Make sure you see at least 5-6 videos of other guys doing it so you can be best prepared.
Overall, I think it is a good option for screen protection, much better than all the NON-FULL GLUE alternatives. Aka, protectors with glue only on the sides of the glass only and not in the middle. It is tricky to apply but once you are done you will be glad you went for it. I am not sure if it is any different than the more expensive versions others people are talking about, I suspect that it is plain re-branding. The more expensive ones just come with a different brand logo, better advertisement and more promises. But, same thing in reality. At least in my case, I paid about 15$ and got 2 glasses, 2 glues, and a good UV lamp.
Quick summary: Find a dust-free flat surface with good light, clean screen, apply stickers to speaker, and all holes and buttons, gently remove any additional dust particles from screen,apply glue to middle of screen, gently place glass on top and DO NOT apply pressure, if it is not too straight you can move it a bit, If any leaks, apply UV light for about 40 seconds up and down, gently clean leaks, apply UV light for 45 seconds for 3 more rounds. At the end you may even do one more 45 second round top to bottom as I did.
Enjoy.
EDIT: After applying it the whole thing, the glue may still remain slightly sticky on the corners, so that may allow extra dust to stick on it. However, If you can, leave the phone under the sun for 10 minutes, and the glue will dry to the full, then it would be easy do fully clean the corners with your nail or some non dusty cloth. Just do not put too much pressure with your nail as you may raise the glass and allow a bubble to form.
I have ordered the same today. lets see when I receive it.
@BABYBOY 3265
Is that compatible with mofi cases? I wanted to order it with one of their fabric type case.

It should be... I don't see why not. The one i ordered covers most of the screen but leaves quite a bit out as you can see in the pics i posted... and that is considered not too case friendly. However to me it seems pretty compatible with all cases.
But, to be safe you can order the alternative case friendly version of the glass from the same seller. It is smaller and covers even less of the screen. I don't see the harm in getting one and trying it
Received mine today. Took 12 days to reach India. The screen guard is really good,fits perfectly. the glue is little excess so had to clean up a lot. note for next time. However I fixed the glass a little to the lower side so bundled case is almost touching the glass. Don't know in future if it will lift because of that. Overall a fantastic deal.
Hello
I received mine yesterday it took about 13 days to get to the EU, and applied it today.
The application when well on the first try,i did watch quite a few tutorials beforehand and that helped alot.
The screen protector is very clear , and you do not notice it at all, it also seems to have some real oleophobic coating.
Tactile responsiveness is on par with what you would get without a screen protector.
All in all a very good alternative to the more expensive competitor you also get two screen protectors and two tubes of glue for the same price.
If you are in the market for a screen protector dont hesitate.
Jay
Just ordered, thanks for the review & tips..
Another positive report here, although I wish I'd been a bit more careful as I have a couple of tiny bubbles near the edge. They only show up on a bright white screen so I may live with them rather than try again with the spare glass & glue.

I have the whitestone and love it. Was wanting something for a backup though. Last time I waited a week to get my warrenty replacement.
Does the AliExpress come with a tray to line up the glass? Or does the glass work with the Whitestone tray? If not, how do you get your glass lined up?

The tray you are talking about probably will work. However the standard way to align the glass is by your finger and vision. Just make sure that if you do so, do not press downwards while you are moving and aligning the glass. If you press down, it will push some of the glue out...
