You can use tons of 3rd party apps to do such thing, just do a little search in the play store
I know that, but 3rd party are either paid, or contain a lot of ads, or from suspicious developers (or all of this =) ). This function from phone manufacturer would unlikely be paid or ad-driven. And I have to trust the manufacturer as long as I'm using a device from it. So this any function out-of-box (especially such privacy-sensitive) would be much more convenient. I know that for sure as BV6000 owner (where it is present).
