Got mine yesterday and noticed the same issue within a couple of mins of use. Left side, middle and I was getting the 'tacky' sound too as it temporarily adhered before losing it's grip again. Looking at the tablet from the side it was also noticeable that the glass was sitting very slightly higher than the metal bezel (1mm or so), whereas on all 3 other sides the glass sits slightly lower than the bezel.



I noticed that the Nexus gets relatively warm on the back on that side (battery or chip?) whilst in use so decided to try holding the glass down with my left hand for 10 mins or so whilst playing a game in the hope this heat and the slight warmth from my hand might help help soften the glue up and rebond itself. So far it seems to have done the trick and the bounce is no longer evident but will give it a few days to see if it starts up again.



The UK retailer I bought from offers a pretty good returns policy so if worse comes to the worst I'll use this one until they get more stock and then RMA it for a replacement.
