The Samsung is determined to be a frustrating repair. 

It's all working but the new case adhesive, it's predecessor having been a [insert vective of choice] to get apart, is now refusing to adhere.  Hey, adhesive, you only have one job.

Hello, glue designer; Little Blue Pointy Things are waiting for you.

Hey ho, the gap's smaller after heating and clamping repeatedly and when the new protective case arrives it'll make the problem go away.  Out of sight...
