    Mine has the issue - pushing down seems to temporarily fix it..we'll see what I end up doing.

    Also, if I apply firm pressure to the bezel (have been doing this to attempt to fix), the display gets those "waves" in it from the pressure. Anyone else have this?

    There have been record temperatures all over the US. Perhaps a batch of these tablets sat in a non-regulated warehouse where it got really hot or perhaps were even stored on their sides instead of on their backs.

    This might sound kind of harsh, but I'll bet if you warm the entire tablet to about 100F, place it into a ziplock bag (to control moisture), then place it face down in the freezer overnight, the glue will be so set by morning you won't have this problem again.

    I think playing a movie or a game is KINDA getting it warm enough to soften the glue, but not hot enough to seat the glass completly. Maybe if you played a higher quality movie than Transformers.....

    You can warm it to 100-120F by leaving it in your car on a sunny day with all the windows rolled up for about 30 minutes. Don't put in on the dash, but put it somewhere where the sun won't hit it and make sure it's face down so the weight of the tablet will press down evenly against the glass when the glue gets gooey. The floor of the front seat should do.
    (You could also place it in the oven as long as you use bake instead of broil and place it the middle rack, an equal distance from the top and bottom heating coils. The temperature should be on WARM. That should be about 100-150F. If you have any doubts, place a piece of white bread in the same spot beforehand and see that it takes forever to turn in to toast.)

    Then, wherever it lies face down, slip the ziplock bag over it while it's still warm and carry it face down by the edges of the bag, not touching the tablet itself. Lay it face down on a counter or a table till its closer to room temperature. Then pick it up by edges of the bag and place it in the freezer, still face down, onto a flat area where the weight still be distributed evenly.

    When you take it out of the freezer a few hours later or the next morning, be aware that, even though the screen is Corning glass, it will still be kind of brittle until it warms back up to room temperature. Wait at least an hour before taking it out of the bag and fiddling with it.

    This is only a suggestion. If I get mine tomorrow and it has this issue, that is what I am going to do.....as long as someone else tries it first. If your tablet can't withstand a little heat and a little cold, then it's not even worth the small amount you paid for it. The battery might explode, but at least the screen will be fixed.

    Enjoy!

    Not to completely discount the adhesive and/or temperature theory, there clearly is a hardware aspect of this as well. Every one of these exhibiting the issue has it occurring on the same side of the device. That is not just a coincidence.

    You are probably right. It sounds like a design flaw that relies entirely too much on glue. I wonder what those iFix folks have to say about it. They are the ones who took one completelty apart to judge it's "fixability" score. They said it seemed well constructed. They might have a suggestion better than my "bake it in the oven/throw it in the freezer" idea.

    Just received My nexus 7 from GP this morning. Inspected the screen for issues and saw no seperation issue . But after handling the screen with my hand noticed a slight play/movement with a small clicking snd (not the nexus snd effect) on the left hand side towards the center.

    No issue with performance yet, but will be watching this for further issues.

    Just called my local GameStop about the separation on mine. I noticed this morning it was back. Since I need my Nexus 7 for work they are ordering a replacement and will have it ready to exchange. Was told likely by the end of the week.

    Actually, all the Game Stop Nexus 7's were made on Monday, while Google Play ones were made Tuesday - Thursday.

    I believe the heat theory because most seperation problems seem to be on the left side, and I think the left side gets the hottest when extended use

    Does the left side get the hottest with extended use?

    Gosh, I read the first post again and I think I completely misunderstood what the problem is. I think these are possible causes for the problem:

    1) The glass is too large for the case and, since the ends are glued securely and giving no quarter, it's bowing the glass upwards in the middle. Since it always seems to be the same edge that separates, I'll bet that was the last part to be pressed down during the assembly process. When you get the tablet warm, the glass softens a little and relaxes back down to the bezel.

    But, it seems when you get it warm, the glass would expand as it heats and the bowing would get worse. So...

    2) The case underneath expands as the device gets warm, allowing the bowed section of glass a place to settle back down to.

    3) There must be too much disparity between the expansion of the case and the expansion of the glass. If they repeatadly expand and contract at different rates, they'll start to come apart.

    4) To counteract the shifting action between the glass and the case, they used a rubber cement that would allow flexing, but chose one with too low a "melting" point(too gooey). IF they chose a glue with too much hardener, the glass would probably break from being stressed and flexed by the shrinking/expanding case it was attached to.

    5) The case and glass do not heat and expand evenly, because the source of heat is greatest near the cpu and other chips, causing that area to flex more.
    If you look on the IFixit website, you can see that the motherboard, including the processor and chipset, are located on the same side of the tablet that is coming apart(the left). It makes sense that this part of the tablet gets the hottest during heavy use. They probably have to peek at that side as they are closing it up to ensure all of the ribbon cables remain connected before "sealing the tomb".

    Nexus 7 Teardown - iFixit

    See the Step 5 photo. The right hand is holding the front of the tablet with it's back to us. That puts the CPU on the left if it was turned back around to face us.

    I think if you turn the tablet off (so that no heat is being generated from the inside), then evenly warm the tablet in a shaded part of a car interior on a hot day or in the oven when it's set on WARM, all edges of the tablet will flex at the same time and the glue will soften evenly. When it cools and contracts evenly, the glue will firm up as everything seats itself evenly. I would not heat the tablet past 100-110F. I don't think you need to place it in the freezer afterwards, per my earlier post.

    Otherwise, it sounds like the trick is to only use the tablet outdoors when it's cold and only play HD movies or 3D video games for 5 minutes at a time, with a 30 minute cool-down intermission. That's not so bad. Just kidding.

    Don't we have any engineers that ordered one of these?

    Good advice, same thing I said yesterday. So if you don't have the problem out of the box, don't allowed the tablet to overheat until the glue is cured.

    I am hopfully hours away from receiving my pre-order tablet via UPS. I am anxious to see if this batch has the same issue as the retail versions. If it doesn't, I guess I will be glad I didn't cancel my order.

    I suggest anyone else buying one retail open it right there in the store in front of the manager or counter employee so you can ask for another one, on the spot. Too bad they won't open all of them ahead of time so customers don't have to deal with the problem when they get home.

    I put in a request for an RMA with Asus and it looks like that's going to be a whole ordeal (with no cross ship). Just going to return to Sam's and not refuse delivery on the Google Play one as I was planning to do. Hopefully will be luckier with that one.

    Hopefully man, I was hoping mine (from GP) wouldn't be defective but unfortunately, It has the separation issue.

    Received my GP Nexus 7 two hours ago. It looks perfect, no sign of screen separation.

    I did notice an adhesive smell when I opened the box. Could be the adhesive had not completely cured when they put it in the box. I'm going easy on letting it get too hot for a few days to let it cure.

    I'm surprised nobody has posted photos of this yet.

    Does it protrude enough to irritate your finger/thumb while holding it? Could it possibly cut you? Does the screen not respond to touch near the effected edge? Does it warp or distort the image near the effected edge?

    Not trying to belittle everyone's problem, but I'm trying to find out if it's something that can be lived with or something that's actually detrimental to using the device.

    Mine looks like it bows to the center on the left side if your looking at the screen and bezel at 45degrees... straight on It looks fine.. it does have a sponge feel to the left side and the corners are flush with the case corners.. I think people maybe looking to hard at this. Lol I'm turn on a movie and see if it gets worse

    Mine has this issue as well. Left side starting from the middle about two inches worth. Not quite as extreme as posted prior. I can run my finger nail up to the metal trim with the glass sitting below the trim. However, on the part where it's raised the glass is ever so slightly higher. It makes a clicking sound when I press on the glass there. Display and touch is not affected.

    I just had mine delivered today from Google.

    I don't think mine would significantly affect performance, but the sound of the adhesive trying to adhere and the spongey feel is definitely annoying. Since my screen also ghosts hardcore, it's getting returned to Staples while my elusive 6/27 order pends.

    Thanks for the impressions guys. Mine just arrived at my apartment and I'll check it as soon as I get home. Hopefully it doesn't have the problem, or if so, it's minor enough to not get bugged by.

    Now that you mention it, I think if it made that spongy feel or the click noise each time I was touching that side of the screen I would get annoyed pretty fast. Hope you get your replacement soon!
