Is UUID different for all devices?

Let's say there are a hundred iPhones and one hundred Android phones.

  1. Are they going to have two hundred different UUIDs?

  2. Is the UUID of a smartphone permanent? It can never be changed?

Thanks a lot, Stack Overflow!!

Solution

  • You can pull out as many UUIDs as you want. The odds of you getting the same UUID again are a trillion to 1.
