Just today I winced when I saw a woman at the supermarket, in the queue in front of me, drop her (seemingly new) white X or XS phone. Landed face down, all cracked up on back and her face was like that Edvard Munch painting lol.
Wife and I came to the conclusion that this works much better without the + and MAX phones. We both tried flipping our MAX phones and ... both did what Joe did initially - THUD - right on the desk. lol.
