GTA6 in-game social media & dual-protagonist switching

GTA6's in-game phone includes a built-in social media system, deeply tied to dual-protagonist switching. This article covers what's known and what's still unconfirmed.
In-game social media
Accessible from the character's phone:
- Scrolling viral videos
- Following in-game influencers / streamers
- Discovering world events and hidden side missions via the feed
The many short social-media-style clips in the first trailer are seen as a teaser of this mechanic.
Dual-protagonist switching
- You can switch between Jason and Lucia during the story, including real-time switching within missions.
- The mechanic resembles GTA5's character switching, but with a stronger emphasis on "partner" cooperative missions.
- Each protagonist reportedly has unique abilities that affect missions and the crime economy.
Still unconfirmed
- Whether free switching in the open world works exactly like GTA5, or is limited to specific missions/story moments, has not been clarified by Rockstar.
- Some details come from retail listings and leaks (e.g. an Amazon Brazil product page); Rockstar has not publicly confirmed everything.
Dual playable protagonists are officially confirmed, but the exact form of free switching is subject to the final release.
