I dunno it’s been around on android sound ice cream sandwich in 2012.What's the point of the Galaxy's facial detection? To say "we have something else" to the FP sensor (which is meant to be more secure)?
You can unlock the S10 w/ your eyes close or photos. Is it worth that much convenience though? To me, no. FaceID is so much better, that I would be missing it so much if I stick with my S10e long-term. I don't like the FP sensor in the power button either.
