Square Trade break testing didn’t show very good results. The verdict: iPhone 8 and iPhone 8 Plus are definitely not very durable (although both phones beat the Note 8).

And I understand the back is not covered under insurance as well.

“Square Trade gave the iPhone 8 a breakability score of 67, the iPhone 8 Plus a breakability score of 74, and the Galaxy Note 8 a breakability score of 80. At 67 and 74, iPhone 8 and 8 Plus are at "medium risk" of breakage from a drop, while the Galaxy Note 8 is at "high risk." The Galaxy Note 8 fared worse because it was non-functional after some of the tests, while the iPhone 8 and 8 Plus remained usable despite the broken glass. “

Once replacing the optical drive does one need to flashit/swap pcb boards. Has Microsoft stopped hard coding these.
