What's your point? If a random pick-pocketer steals a phone from me, they don't care about accessing my data. If they wanted to, it's easier with face/fingerprint recognition. Just grab my picture from facebook/twitter/find me by email or phone number, fingerprints are on my phone, batter, sim card, screen... everywhere. It's slightly more expensive than printing my picture from facebook but many times proven, doable. On the other hand... how can you guess my pattern lock or SHITYPassword1111?

If I'm a victim of a targetted attack, better not to have a phone at all.
