yep, mine has a really thin gap on the left side between the screen and bezel... it occasionally collects dust and i have to blow it out with a blower....
The first ipad mini i got had a loose screen on the exact same side. Everytime i pushed on the left side it will click downwards. Had to exchange that ....
seems like ipad mini have a problem on the left size of the screen
I am not sure if it warrants another exchange .....
