A friend got a new high end 2019 Samsung phone. The week it came, we were at the beach. I offered my USB battery. They used a USB-C to USB-C charge cable to connect it. They passed the phone-and-battery to me and I grabbed it by the cable , as I would with a lightning cable.<p>The USB-C detached from the phone and the phone fell 3.5 feet onto the rocky sand. It immediately broke the rear glass.<p>After that experience, I'm still skeptical if the friction available in the USB-C socket is up to the task of day-to-day phone use (vs lightning).
Among other challenges, Apple must have been struggling with this all along.
