Last to leave their metal home are the two AMOLED displays. And behind them is some of that copper we were looking for!

Samsung has long lined their displays with copper to help disperse heat—and that's still the case here, despite the switch to the graphite underneath the motherboard.

Both these phones share the code name Canvas. Not quite as clever as last year's Davinci, but apt nonetheless.

The back side of each display hosts an integrated ultrasonic fingerprint sensor. Meanwhile, Corning's new Gorilla Glass Victus protects the front—promising "significant improvement in both drop and scratch performance, for the first time ever in the Gorilla Glass family."
