I've notice that my screen ripples alot on the left side of the screen. It doesn't really take that much force to cause it. Is this a defect in the product or just a case of thin glass? The screen touch sensitivity works just fine just has ripple effect when pressing on the screen lightly.
My N7 does this a little when there's slight pressure on the center left side of the screen. It happens in the same place that I get minor screen lifting and creaking. Maybe it has something to do with the glass being pressed too close to the screen. I've had a number of iPod Touch 4th generation devices that have the effect you're describing so it isn't just limited to this first batch of N7.
I think if you're having to press it deliberately to see it and it doesn't show in normal use, it might not be an issue, as it isn't for me. But then again I have several other issues with my N7 that bother me a lot more.
If you do see it regularly in normal use, I think it would be reasonable to get a replacement.
I not a "serious" problem to me yet but it only really happens if i tap the screen with my nail oppose to my thumb / finger tips.
Usually this is a consequence of screen lifting. Many units are having adhesive failures on the left side of the display, causing it to lift up.
To check for screen lifting, hold the device at eye level with the right portrait side closest to you. Look across the display and hold it so the left bezel is visible as a thin, silver line. If the display is flush, it will not interrupt that line. If the black cuts into the silver, you know that the adhesive on the left side of your display is starting to fail.
But for what you're experiencing to happen, such a subtle test is usually unnecessary. Just look at that edge and see if it moves when you press it. It may feel spongey or make a creaking noise.
This defect does qualify you for an exchange. If your screen distorts under pressure that's not good for it, and all that bending will shorten the lifespan of your device. Also, if there is separation it may progress and become noticeable during normal use.

Gotcha. Yeah, it's one of those things that once you notice it's hard to ignore. Just as it is with all the other N7 issues and electronic devices in general.
Does it do it just on the edge of the left area of the screen or closer to the middle?
You generally don't want to be using your nail to use the screen, but I can see how that would illustrate the effect.
I completely agree with the above poster.

I don't see any sort of screen separation, screen looks as flush as it should be. Plus I have no creaking noise and/or spongey effect. :\

I agree once I found it it now bugs me lol. It happens not really towards the middle just maybe a centimeter above the status bar at the bottom.

Perhaps I am a bit OCD about my phones, but I have dropped my hd2 (unprotected) at least 3 times. One time from about 2 feet onto a rug, and the other two times about 1 foot to the wood table. Now, I have noticed some very fine scratches, maybe cracks in the screen. If it were a crack, should the screen give way to pressure, even if it is very small? I am only asking this because I feel though my next drop will be on pavement.
If you look at your screen in strong sun light at an angle with the screen turned off you will be able to see faint diagonal lines criss crossing the screen as well as a pattern of dots. These are all part of the touch screen and normal. If you have any irregular lines which aren't surface scratches then yes, these could be stress fractures in one of the screen layers.
Slight pressure shouldn't make them crack but they won't get any better, especially if you keep dropping it. Get a case, or some really strong glue to stick the phone to your hand!
Looks like the digitizer has been damaged from your accidental drops.
Keep an eye on it and if functionality stops working then the whole unit - LCD and digitizer must be replaced.
Good luck
Is there a way to distinguish small scratches from cracks? I can see some light lines from the right of the the phone's screen when in sunlight, starting from the very edge. You would think that most scratches would occur on the screen, where you actually use the phone. And yeah, I just bought an otterbox defender.
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.
I've got the screen separation problem, and if I press hard enough on the left side of the bezel my screen distorts at the left side a bit. Will this damage the tablet long-term?

Stop squeezing it. Open the case and tighten a few screws or live with it, it won't damage it unless you're pushing it all the time.

I am unsure, but many people believe flexing the screen will cause undue stress and shorten the life of the display.

That fix has proven ineffective. Screen lifting is most likely caused by adhesive failure on the narrowest shelf that holds the display.

After owning my Tegra 7 for a few weeks now, I only just realised that the digizer actually extends out further than the visible screen on all sides of the bezel - in fact, the touch sensitivity goes almost to the edge. I'm not sure yet whether I like this. It does make it easier to scroll. But I have a feeling that some of the funny touch screen issues I've been having might b be caused because I've been holding the tablet on the bezel - beyond the LCD screen, but it is still picking up my touch.
Can others confirm this on their devices?
Yeah me too, i can scroll while touching the black bezel of the digitizer.

I second that...causes some unintended inputs at times.
I think I found a hardware defect on my phone.
It doesn't affect the functions of the phone whatsoever, but it's a defect nonetheless.
There is a tiny tiny hole underneath the gorilla glass on the black bezel between the screen protector and the case. See attached picture, where the red circle is. This hole is super tiny, I can't see it under well lit room or outside or even in the attached pic. I'm sharing this for the location of the hole so maybe others can check on their phone if there is such hole. If I check in a complete dark room, I can see it. And it's visible only from certain angle, as the pic was taken. Screen has to be on, in order to see the light being emitted from this tiny hole, I'm talking about less than a normal needle point. It has no effect on how the phone work, but I found this last night. At first I thought it's a speck of dust, but it wouldn't go away whatever I did. Then I realized it's a light coming through under the gorilla glass. I'm not going to return the phone for this, but still it's a defect.
Check your phone and let me know if anybody has same problem ?
Mine does not have this problem.
None here
