NDL top screen replacement.

I recently just purchased a top screen replacement. When i bought it it was great condition, but there is this protective plastic screen protector on it, and some air bubbles between the film and screen. When i replace the screen do i just remove the plastic? or should i keep it? And do i try and remove the air bubbles if i keep it? thanks

Just remove it. It's just to keep it from getting scratched when it was shipped from the factory to wherever you purchased it from.
