Why isn’t my home button working?

Home button doesn’t work and pop-ups keep coming up about unable to use touch ID touch ID failed to update.

here are some clues:

• first generation iPhone SE
• no obvious correlations like replacing the screen or replacing the home button
• stopped suddenly but not after any iOS update
• had transferred info to a new iPhone SE approximately two months earlier which continues to work well with the touch ID and has no problems with the home button
• restart phone reset to factory settings has not helped
• cleaning the button with rubbing alcohol has not helped
• have yet to test punching it like Mike Tyson as possible fix
