(S7 Oreo update) Do I have to use Samsung default message app for RCS?

brager722

    Hi.

    So I just got the new Android 8.0 Oreo with Samsung experience 9.0 on my S7 and I noticed TMobile added Universal Profile 1.0 RCS update on my phone. I would like to use it. Is it currently available?

    But my main question is do I have to use Samsung default messages app or can I use Android Messages app?

     

    Thanks.
