Here's another excellent idea that will keep people's information like contact's, accounts etc. in the their phone's more safe. Have an option to turn off the pattern password (seeing as if your screen breaks and you can't use the pattern..you have the fingerprint sensor) and make it fingerprint only. Seeing as it automatically requires you at the beginning to have a pattern, give us the option to turn it off after. All these drones in the sky makes that feature useless if some one can just fly by your house and see what your pattern, pin whatever password is. It'll make it to where those losing their phone's, stolen or whatever, don't have to worry about their information being given out to some one listening to them and would have to factory reset the phone if the phone was their only objective. End result, fingerprint password only.
