Google Messages users report that Rich Communication Services (RCS) stops working for some accounts, showing a “3100” error. Multiple outlets describe the problem as breaking RCS service within Google Messages rather than affecting SMS, with affected users unable to use RCS features after encountering the error.
Context suggests the issue is concentrated among people using Samsung Galaxy devices and, specifically, those who have moved data between devices. Android Central says Smart Switch may be responsible after users transfer settings or accounts, while 9to5Google also points to Galaxy switchers and indicates the disruption is tied to that group of users. Both accounts frame the “3100” error as a recurring symptom, implying a server-side or account-configuration mismatch triggered by device switching and/or data transfer.
The differing angles are mainly in emphasis: one outlet focuses on the error code and the broader pattern among Galaxy users, while the other highlights Smart Switch as the likely trigger after the transfer process. Neither source describes a long-term fix in the material provided, only the observed breakage and likely correlation with Samsung migration workflows.
