MY iPhone 6 home button does not take me to the homepage. It recognises my Touch ID. It does not work to close a program, I have to urn my phone off and back on to get from one page to another.
To make sure that this is not software related, set it back to factory settings, without using any backup data afterwards. Set up the rest of the personal settings manually and test the home button. If it still does not work, this is a hardware issue and the phone has to be serviced by Apple or an Authorized Apple Service Provider:
