Siri doesnot work on my I phone 6. Airplane mode is off, siri is on. Volume is up.

You probably haven't set it up. Go on settings, touch id and do it.

Stick your finger through the screen, or just Tap harder or lighter of for longer…

Go to Settings, General, Accessibility and then 3D Touch to see if it is enable. Also 3D touch is not available for all apps yet.

Take it to the nearest Apple Store and in case if you need a good app to hide your private stuffs you can use Leo Privacy Guard.
