All phones with type c

Not true. My phone, a Pixel, has USB 3.1 Gen 1. The Galaxy S8 is also USB 3.1 but I'm unable to find which gen it is from five minutes' Googling.

The Nokia tablet is the first that comes to mind: https://en.wikipedia.org/wiki/Nokia_N1

That's over two-and-a-half years old though. The kinds of devices using USB-C that are coming out nowadays are using USB 3.1.

Some smartphones.

Older ones maybe. The latest generations of flagship phones use USB 3.1 over Type-C.
