I wonder if the option to stay with a person might work with kids. My cousin does tons of live videos on Facebook with her kids. When she's doing their sporting events, they end up too far to see who is who. She couldn't afford the phone now, but just thought this might work for that.
Only a gimmick for those who don't use it. In the other thread I mention how iris scanning never worked for me with my glasses. It is a gimmick on my phone but other are upset about the loss of it.
