I understand and you’re correct for bitcoiners. But for the majority of people verifying something on a different screen is already to difficult. Especially a bitcoin address. I can imagine that people actually just buy these devices to sign transactions and save their bitcoin that’s it. No physical backups, just two of these devices with the same keys synced. They’re fingerprint protected so they’ll just lay them in two separate locations. If this syncing would be possible I’m curious if they would be able to this device to device via bluetooth for instance. You wouldn’t want the keys to touch the phone.
