My iPhone 6 is totaled and I was wondering if there was any way to fix it?

The screen itself is starting to fall of the phone and is not responsive at all when i plug it into an outlet, however the phone itself makes a continuous charging sound every few seconds. Also some of the frame under the screen is starting to come off too. The phone itself isn't damaged just the screen but i don't know if the screen is replaceable. Can anyone give any suggestions on what to do?

Take it to an Apple Store of course.
