Here it is! Just got my Nexus 7 but a really bad surprise waited me. As soon as I opened the box, I experienced the "screen separation" issue that a lot of people had. I tried to look on the web for a real permanent fix as Google's supply are not able to bet me an exchange/RMA that would not require to open the back of the device. I had tried to get the screws tighten without success, I also tried to put spacers in between the screws without success also.. :crying:

I read a lot about fixing this issue; one was explaining how to make the CPU/GPU running and generating heat to get the glue to hold the screen and case together. So I was sitting there watching my battery temp going up to 32-35C/90-95F as my meal was in the oven at 190C/375F. Then I got this great idea. I stopped the stress test, put the tablet in power off state and placed it face down on TOP of the hot spot of the oven; in between the two front elements. I put weigh on top of it and waited about 30-40 min. After that period, I started "Stability Test" available on the Play Store to get the battery temp that was around 47C/115F. I stopped the oven and let it sit for the night face down with weigh on top of it to cool it off. Next morning, surprise! The screen was finally glued. I had no screen seperation since then. It's now being my 5th day without any problem.

Conclusion : FIXED !! :laugh:

Let me know if that worked for you as well !

Interesting idea, hadn't heard that one before. Of course, different stoves will have different hot spots from the oven, so YMMV. How much weight did you put on top of it? Also, do you happen to have a way of measuring how hot the spot gets?

I'd be interested to see if this is a truly permanent solution or if the adhesive starts to break down again after a few weeks or months.

I placed my hand over and touched it.. If the "hot spot" was couple of degres higher, I wouldn't be able to let my hand sit there.. I was at the limit.. For the weight, I used casino's pot full of change.. 2x 8 pounds..

Good to know. Different people seem to have different thresholds for heat (for instance, I remember as a kid I couldn't keep my hands under the same water my mom used to wash dishes), but the spot on my stove doesn't seem to run as hot as you described, so I'd be willing to try it if I run into this issue on my replacement.

All in all, though, I like this idea a lot. There's always a risk, but I'm sure the devices are stress tested with the CPU running at temps hotter than you could reproduce using this method (short of actually putting it inside the oven). As long as you can hold your hand on the spot without it getting too unbearable, I would think it's pretty safe to try.

Is there any way that we could just use our better glue to stick the screen tight regardless of the heat when playing games?

regarding heat-guns .... do you think a hairdryer would get hot enough/ too hot etc? I'm keen to try this but dont want to mess it up.




I'm on my 2nd N7 and have screen lift again :(

shocking discovery- missing screws in nexus 7

Long story short:
1st device from best buy : scar like dead pixels, exchanged for second
2nd device from best buy: loose screen/ seperation
Got 3rd device from staples hoping it is better, noticed screen noticeably yellower, minimal seperation problem.

At my last resort, opened up the 2nd and 3rd device, found 3 screws missing from the right side when faced down(or left when screen is up). While the 3rd device is missing one,
. I am so shocked this is happening....no wonder my screen is so loose.

I m a first timer with android device. Own an iphone . Gotta say jelly bean and even the nexus 7 itself is spectacular. But what is with Asus? Have google picked the wrong partner. Or is it is pure poor quality control. Unbelievable.

Okay, so just to make sure what you people do:

1. Heat up the oven
2. Find the hotspot
3. Switch oven off, wait until hot to touch (that'd be a bit over 60C)
4. Switch unit off
5. Put the unit on the hot spot with about 16 pounds (8 kilos) of pressure on top (really?)
6. Wait until it has cooled down naturally

Am I missing anything? How has the fix held for you so far after a month or more?

Thanks, :cyclops:

Did not work for me.

I heated the device to 80C with a hairdryer, then pressed it with clamps (force equal to about 9kg) for about 7 hours.

Separation came back about 1 hour after I released the clamps without turning the device on.

Too bad, as I have no way to exchange it.

I guess I'll just use the case.

5 minute epoxy (or any glue one's comfortable with) is the way to go. The problem is obvious once the bevel is removed - the glue on the left side on my device had cured without holding the glass. Hard to believe heating and pressing would work at all.
