I wonder if Samsung has a similar issue with the fingerprint readers on their devices. Has anyone here owned one and needed to replace it?

Apple never fixes the button, they just give you a new phone. I'm not sure if they're able to reset the key assignment and put in a new fingerprint sensor. Being able to do so would be a major security flaw.

It's like the proprietary cables that Apple supplies for its devices. They have security chips in them that verify that they are proper, secure cables to the device. That way Apple sells lots and lots of these cables, and no-one's able to try gain entry into the device through attacking the USB controller in the cable to feed it bad data.
