Don't be afraid of fixing your screen!
I didn't want to start a new thread regarding the screen lift issue,bit the solution is extremely simple even my grandma could do it!
I started to expirience the screen lift issue. A few weeks ago it started with a kind of creaking sound coming from one of the sides of the screen....with my finger I could feel that the display glass was slightly higher than the bezel on the side while the rest of the display sat slightly recessed. After some time this issue only became worse with one side of the display protruding by at a couple of milimetres, something had to be done.... I'm well versed in hardware repair but this issue found me lazy and in bed.
These are the steps I took while still under my blankets:
-used my thumb nail to separate the display from the backing case. Was extremely easy, I started exactly in the center of the top (behind the camera and in between where the textured back meets the silver bezel.)
-ran my thumb nail around the entire bezel, at times gently using my fingers to lift a little and the nexus backing easily popped off...very easily
-with the backing off now the screws that tighten the display down were exposed around the perimeter of the logic board/ motherboard ...took a precision Phillips and tightened them all up, they were loose.
-snapped the back back on, good as new
