So do I. Touch ID is extremely fast on it. Perhaps you haven't scanned your fingerprint properly, your home button needs a wipe, or you have a defective unit.
It also might be my fingerprints, I will look into it if I get it fixed.
Nonsense. I had a 6s and it was very fast. Your phone is defective. Take it to Apple to get it fixed.
Even this one was meant to mean: "my iPhone 6S", I am not saying all iPhone 6S's are slow, guess it's my fingerprints or my TouchId is faulty.
