Google Messages RCS Bug Hits Samsung Switchers With 3100 Error After Smart Switch

Summary
Google says some Samsung Galaxy users losing RCS in Messages after device transfers may be hitting corrupted cache files carried over by Samsung Smart Switch, often surfacing as error 3100.
Google’s suggested fix—update Messages, turn off RCS, clear Carrier Services data, restart, then re-enable RCS—did not resolve the problem for at least one reported user.
A factory reset followed by setting up the phone without Smart Switch restored RCS for one user, while another case tied to a Verizon-from-AT&T move appeared linked to an incomplete number port.
A six-step community workaround reportedly fixed some affected phones, and users planning a switch are being advised to disable RCS before transferring or porting and re-enable it only after carrier confirmation.
