Screen Distortion / Ripple - Nexus 7 General

Does anyone else have this problem:
When you're just pressing a bit harder than the usual touch, on the top and bottom Left side bezel, it causes the Screen to ripple (fluid wave effect).
Not even pushing down too hard, just a firmer press than usual. This is easy too see on a darker background, like the default background when the device wakes up and still in locked mode.
Yes I realize it's a LCD screen, plus this Corning glass is thinner, and we're not always pressing it that hard to notice anyway.
But the Right side bezel and other areas are mostly fine,
So I'm wondering if it's a defect on my device or not (the left side being too sensitive)? would this cause further problem in the future? And it could be a concern if I carry the Nexus 7 in the backpack and other items pressing on it.
Other reports on this:

"the display can give a little and cause the LCD to ripple if you really press hard against the screen"

I wonder if I try the Fix on the other thread, taking off the cover, but instead, loosen the screws a bit on the left side, would that help?
Thanks!

Hi,
My device has this too. Mostly on the left side & a little less on the right side but hardly any on the top or bottom.

Is your Kaiser wobbly / sloped ?

Been very happy with the Kaiser so far, including on the GPS front ;-) but I'm getting slightly annoyed by two hardware nits :
1. wobbly : in portrait mode when I tap on the screen the right side tends to "hit" the keyboard part underneath and looking closely it's easy to understand why, there is a tiny gap between the two parts, likely for the slide/tilt mechanism
2. sloped : when I pull out the keyboard, the right side of the screen goes out more than the left side so it is slightly sloped. It improved a bit when folding the screen. Again I think this is a constraint of the slide/tilt mechanism
I'm thinking it's a general quirk because I had to change my first model (stuck key) and it had the same problems.
Anyone else noticed that ?
in portrait mode my kaiser seems to be spaced the same all the way around and doesnt push on the keyboard when tapping the screen. I do notice what you mean by the keyboard appearing to be farther out on the right side but after taking a closer look it just seems that way because of the face plate not being uniform all the way down (part where it flares out on the left side). Mine is exactly pushed out on both sides.

Mine's the same as this. It sounds like yours may not be quite right and I'd consider getting a replacement. Of course, if you can live with it, and the functionality is all there then it's entirely up to you.
For the sloping I've had two and they were both the same, so it's probably a design constraint, no biggie.
For the "wobbling", it comes and goes, I can only really feel the "knocks" when I hold the left side tight and tap on the scroll bar on the right, again, no biggie.
solution
iv had the same problem of one end sticking out,
iv gone around it by inserting some tiny smugged paper into the sliding slots at the back, resolves the issue quite well.
I don't seem to have either problem (TyTN II version).

Pressure on the screen

Hey guys, there seems to be something a little irregular with the screen. When I press on the screen anywhere, there is a spot on the screen that appears to be what looks like pressure being exerted on it. Just like how it looks when you press on the LCD screen of a laptop. This happens also when i press on the case at the top on the left side. The spot I am talking about is about 1 in down from the top of the screen and about 1.5cm to the right from the left of the screen. It is not easily seen unless the screen is displaying a very dark background.
There is a membrane over the surface of the screen that will flex as any pressure is applied to the touch screen, both by the pen and by the frame. If you look at it through polarized sunglasses you can see the effect of any pressure quite dramatically. Unless the screen is malfunctioning or there is color distortion, I don't see a problem.

i dont think thats what hes talking about, he makes it sound like whne he touches the screen a "lcd ripple" appears somewhere else on the screen.
Mine does this when i slide hte keyboard, i can see one in the middle, it kinda worries me, especially since my last kaiser's screen broke and i didnt do anything, i just took it out of my pocket and it was like that.

Screen ripples effect

Hi All
I'm on my second Diamond, first was a grey import, 2nd is a UK spec model. I've noticed that when pressing the screen towards the bottom left and right that there are ripple effects on ther screen. This only happens when I use my finger, not stylus. This is similar to what you get on a TFT screen on a laptop or desktop.
Is this normal, as I can't re-collect this on my first diamond.
Thanks.
you press to strong.
i only notice this when i press with a greater force or my fingernail at the edge on the display.
I have the same ripple effect on my UK Diamond to, even when pressing gently with your fingernail it still rippled on the bottom left. The rest of the screen is fine though, doesn't matter how hard you press you don't get the ripple effect.

screen defect?

I just got a tilt about a week ago and ive noticed that in the middle of the screen there seems to be a purple greenish tint when put against incandescent light. The size of said glint varies in size but i'm unable to see what changes the size. Not sure if its heat or pressure or something. The touch screen works perfectly its just really annoying to always see such an annoying glint.
An interesting discovery is that when i press all four corners of the screen it disappears and when i press in the middle of the little square it seems to spread out. I feel like theres some kind of material or something in the touch screen that is causing this due to pressure. I keep it in a hard case in my pocket so the screen isnt pressed on inadvertently.
I've searched the forum for any answers but i havent seen anything about it. Any response or help would be greatly appreciated. I'll try to get a picture of it up asap but i left my camera at a friends house and dont know when im getting it back...thanks in advanced

Do you see the same "annoying glint" under neon light (not day / sunlight)?
Lots of NOKIA and SONY ERICSSON phones for example get this screen recolorization under direct sunlight - this has nothing to do with the screen being defective but with the plastic above the screen which breaks the light and shows you this colored spots. If you can't see the same spot under direct neon light then this might be the cause.
It is normal that you get color changes while pressing the screen in. First of, you press / bent the protecting plastic and the liquid within the screen which causes the incoming light to break in a different angle, therefore the color changes. (BTW: you shouldn't do that too often, it can cause permanent stains on your screen!).
There sure is the possibility that your screen gets pressure from underneath due bad assembling! If you're still under warranty, try to get a replacement.
yeah you cant see it in day light. but i feel as though there is constant pressure on the screen between the plastic and liquid since the spot is always there and doesnt really go away (unless of course in daylight).
well im thinking im going to go back for a replacement. thanks for the quick answer!

A multi-touch issue masquerading as a touch sensitivity issue?

Ok, so I thought I was having a touch sensitivity problem on my Nexus 4, because often a touch or a swipe would go unrecognized...
Then I realized I was noticing it especially in these two situations:
-Turning wifi slider switch on/off
-Swiping back to a previous tab in chrome
Turns out, what was going on was when I reached that far with the thumb, my palm was touching the curved edge of the screen, making it think I was already touching with a different finger. This "numbed" the screen from my intended touch until I shifted my hand slightly, releasing the unintended multi-touch situation. This made the issue seem sporadic.
I am not saying this is what all other people are experiencing, I am just putting it out there in case someone else is unknowingly doing the same thing. I could also imagine typing errors on the far side of the keyboard for people with certain hand shapes.
It seems almost unavoidable due to the thin bezel and rounded edge, but I would think problem could be avoided with some clever "palm touch near edge" recognition code, but until then I just have to get used to not gripping the phone so tight.

I think that might be the case also. In some instances, it seems like I can't tap on the screen, but it can swipe and if I reposition my hand, it will work.
