I didn't know it was possible on galaxy s8 to see when a person has read a text, until one day my friend texted me and when i replied, it said delivered and then read. It also shows when he is typing to me… This does not happened with anyone but him so I'm wondering why his text are on a different setting and how to put everyone else on the same setting. Also just fyi, i'm using the default text messages and when i send him text, my sent messages are green versus the orange text that i send everybody else.
