Bluetooth and Touch ID not functional

Hi,

So I have an iPhone 6, and I've had a long time issue with touch ID and Bluetooth not working. I'm not the first owner of the iPhone, so I am not sure when or how this started. The problem is that wifi works, but Bluetooth just keeps spinning without the on/off toggle. I was also hoping to knock out the second problem in one thread, touch ID isn't functional too, I have tried setting it up, but it always shows an error saying unable to complete touch ID setup, other functions that use the home button also aren't functional, like reachability, but the basic function of going home, and switching between apps still works
