Samsung RCS messaging problems are affecting some owners of newer Galaxy smartphones, with Google now investigating error reports linked to the service. Users of Google Messages have reported difficulties accessing RCS on recent handsets, particularly after moving to a new device or changing mobile networks.
According to reports circulating across Reddit threads and Android-focused websites, affected users are encountering error code 3100, a connection error, when attempting to use Google Messages. The issue appears most common among people switching to new Samsung phones, including the Galaxy S26 and Galaxy Z Fold, or those changing carriers.
“We’re aware of this issue and are working with our carrier partners to get it fixed as soon as possible,” a Google spokesperson said. A Samsung spokesperson did not immediately respond to a request for comment.
Possible Causes and Workarounds
The problem may also affect people who used Samsung’s Smart Switch feature to transfer data to a new phone. Suggested workarounds vary widely, ranging from a six-step process that involves turning off two-step verification and removing Google Play Services updates, to using a VPN to connect through another country before attempting RCS again.
Other proposed fixes include performing a factory reset. For those planning ahead, some users recommend switching off RCS messaging before migrating to a new Android device or changing carriers, which may help avoid the error entirely.
The Rise of RCS
For years, Google promoted RCS, which stands for Rich Communication Services, as a successor to SMS. The company hoped Apple would adopt the protocol, something that eventually happened in 2024. RCS allows Android and iOS users to message each other in ways that bridge the gap between the two operating systems.
Later in 2024, Samsung formally partnered with Google to ensure RCS worked well on Samsung devices running Android. Samsung subsequently discontinued its Samsung Messages app, which went dark in July, encouraging customers to switch to Google’s Messages app instead.
Apple and Google began adding end-to-end encryption to their RCS services during the summer, strengthening the privacy of messages sent between the two platforms.
