You can almost make out that there's a phone in there!
Luckily, Samsung had plenty of Galaxy S10 5G phones to show off, though these are best thought of working prototypes, rather than finished devices. That means my first impressions here are subject to change, and so is Samsung's software. In fact, I hope some of it will improve.
