Google Messages moves closer to RCS video call support

New strings and internal checks in the Google Messages beta point to ongoing work on native video calls via the RCS Universal Profile 4.0 standard. The feature is not live yet, but Google keeps building out the UI.

• RCS Universal Profile 4.0 adds native video calls inside chats
• Beta build messages.android_20260924_00_RC00 contains call confirmation screen strings
• First references to RCS video calls appeared in May 2026
• No working video call interface is available in the app yet
