For those of you who have tried the various fixes on this forum and are having no luck with the screen lift issue, then this fix may be for you. I believe the screen lifting from the frame is caused by something internal that is pushing the screen upwards and causing the adhesive failure. This fix will use glue to re-establish the bond between the screen and the frame.
This fix involves taking the back cover off and removing some screws and creating a gap between the frame and screen for the glue. Oh, and while the glue cures, you will not be able to use your device for at least a few hours depending on the glue you use.
If this is too much for you or if you are addicted to your device and cannot put it down to let the glue cure, there is an alternate glue fix that is faster, does not require any disassembly, but it uses super-glue - which dries too fast for my liking.

I'm not responsible if you break your device doing this fix.
Tools required
1. Guitar pick - or something flat to remove back cover
2. Small phillips head screwdriver
3. Toothpick
4. Glue
5. Damp cloth/ cloth - to wipe excess glue
6. Needle or tack - to apply glue.
7. Rubber bands, eraser, book - anything to keep screen in place and frame against the screen.
First things first. the glue I used is not super-glue, it is epoxy. Why? Because I've had much success using it, but not much luck with super-glue. See pic of the epoxy I used.
Since most of us have screen lift on the left side, these instructions assume the fix will be on that side.
Steps:
1. Turn off N7 and take back cover off
2. Remove the 4 screws on the left side.
3. Take the toothpick and cut it in half. It should now look like this:
4. Now flip the N7 over. Using the guitar pick (or the tool you used to take back cover off). CAREFULLY insert between the frame and screen to create an initial gap. then take one side of the toothpick and insert it to one side of the guitar pick. then take the other side of the toothpick and insert it to the other side of the guitar pick. take guitar pick out, it should now look like this:
5. Open up the glue. Squeeze a pea size amount onto a disposable piece of hard plastic. Even though the one I bought is self-mixing, I mixed it again using the tack, then used the damp cloth to clean off the tack.
6. Take the tack and dip it into the glue. The tack should now have some glue on the tip. CAREFULLY place glue in the gap you created in step 4. You do not need to fill it up, just a small amount. You can either place the glue continuously or spaced out at even points. I chose to put glue at evenly spaced out points approx 1/4" apart. Alternatively, the glue came with a fine tipped applicator (see pic), so you could have applied the glue directly into the gap, but that could be messy.
7. When the glue has been applied, remove the toothpicks and close the gap. Some glue will be squeezed out so wipe it off with the damp cloth. Flip N7 over and put the screws back.
8. take rubber bands and place them evenly spaced around the N7 to keep frame against the glass. then put an eraser on the screen to keep screen flush with frame. LEAVE THE BACK COVER OFF. You do not want anything that could possibly push the screen up at this point.
9. After putting screws back and applying rubber bands, double-check to see that there is no gap and the screen is flush with frame (similar to the right side).
10. I placed a phone book on top which I did not include in the picture.
11. If everything looks fine, let sit for at least 2 hours before touching it. If you used the same epoxy glue I did, I would not turn it on for at least 10 hours. I also did not put the back cover on until the 10 hour mark.
Final result.
I did this about 2 days ago. Since then, I've tested it by running some tegra 3 optimized games like Zen pinball and riptide until the rear lower left of the N7 felt quite warm. I know that when I performed the shim fix and the screw tightening, the screen would have lifted at this point - but it didn't with this glue fix. In fact, after gluing the frame to the screen, it feels more solid because there is no longer any sponginess when holding with my left hand and absolutely no creaks. Also, it feels good to see that after you've punished the tegra 3 chipset, the heat generated didn't cause the screen to lift.
Hope this helps some of you. If you feel that I missed something or have some suggestions, please let me know.
Cheers.
