Oh nice, I have a Carbon X1. I knew that fprintd has worked for a while, and has allowed me to enroll fingerprints, but has never successfully worked for authentication.
I've been using android since 2010, and it's gotten significantly better over the years. There's only a few things it doesn't back up, like text messages and app data, most of which you don't need.
I find it hilarious that they're like "It's 14F! Break out the shorts and T-shirts!" Meanwhile anyone anywhere else (except the Arctic regions) is like "This is pretty fucking cold".
