iPhone 6S Homebutton/ Touch ID

Hello, the home button on my iPhone 6S seems to make a much louder noise than the one on my old 6. Also it gets stuck sometimes and is hard to press down on. Also Touch ID sporadically won't recognize that a finger is even on the home button. It's not that it's the wrong part of the finger or anything, Touch ID just doesn't recognize that a finger is on it. Is this a reoccurring problem with other users and how can I solve it?
