After the Galaxy S7 and Galaxy S7 edge were updated to support RCS Universal Profile 1.0 back in June, T-Mobile is now updating more devices with the feature.
The Samsung Galaxy S8 and Galaxy S8+ are now receiving updates that include RCS Universal Profile 1.0 support. This feature brings improvements to the native messaging app, like 100MB attachments and 100 person group chats, so long as you’re messaging a person who also has RCS Universal Profile 1.0. Sprint previously partnered with Google to roll out RCS messaging support.
In addition to the RCS Universal Profile 1.0, this update for the Galaxy S8 and S8+ brings the October 1, 2018 Android security patches. The Galaxy S8 is receiving version G950USQU5CRIB, while the S8+ is getting G955USQU5CRIB. If you haven’t gotten your update yet, you can check for it manually by going into Settings > Software update > Download updates manually.
T-Mobile is also updating its Galaxy S7 and Galaxy S7 edge. These phones are receiving the October security patches, too, along with “various bug fixes and system improvements”. As with the GS8 and GS8+, you Galaxy S7 and S7 edge owners can check for your update by going into Settings > Software update > Download updates manually.
