How well would it work if it's not supported natively by Android? I mean the current issue right now on iOS is that only few Apple and major apps have that feature. I would think there will be zero 3rd party app using this feature on Android if it's not natively supported by the OS.

The mate s came out before the 6s and 6s plus. The technology is slightly different.
