Touch ID doesn't work when it's plugged in?

I've had my iPhone 6 for almost 2 months. I got it around mid-June. And this problem is persistent. I can't plug it in to its charger, to headphones, or an aux cord. The Touch ID just stops working. Force touch still works, and so does the home button. But Touch ID doesn't.

A couple reasons why your Touch ID is probably not working is because: - your finger/phone is wet - when you trigger security overrides - when the sensor is dirty. You may want to contact with The apple people.

Retrain the phone to recognize your fingerprints. And the iPhone 6 doesn't have force touch.
