Galaxy Users Hit by Message App Glitch

Samsung Galaxy users are experiencing RCS failures in Google Messages after transferring data to a new device with Samsung Smart Switch. Some see error code 3100 when trying to enable RCS or send messages on their new phones.

Google says it is aware of the problem and believes corrupted cache files from Smart Switch may be to blame.

RCS Failures After Smart Switch Transfers

The problem appears after using Smart Switch to transfer data to a new Galaxy device. Google Messages RCS failures have been reported by several Reddit users after moving to a new Galaxy phone and transferring data with Smart Switch.

Those affected see error code 3100 when trying to enable or send RCS messages. Google believes the issue may be linked to corrupted cache files transferred during the Smart Switch process.

The fact that Google Messages is the only app on Galaxy phones that supports RCS makes it the default choice for users, especially after Samsung discontinued its Messages app in the US. As a result, both new and existing users have switched to Google Messages, leading to a larger user base that may be affected by this issue.

Workaround and Fix Status

Google suggests several steps to try to restore RCS, but these do not work for everyone:

Update to the latest version of Google Messages.
Turn off RCS in the app settings.
Clear the Carrier Services app data.

Android Central notes this workaround does not appear to work for all affected users. Some say they were only able to restore RCS after factory resetting their Galaxy phone, and even then there is no guarantee it solves the problem, making a factory reset a drastic step to attempt.

Google says it is aware of these reports and is working with carrier partners on a solution. There is currently no guaranteed fix for everyone. Google has not given a timeline for a broader fix, so affected users may need to try the suggested workaround and wait for a carrier-side solution instead of relying on a factory reset.

Some users also report RCS problems after switching carriers instead of devices. Google says these cases may be due to the number-porting process not being fully completed.
