Google Messages RCS is breaking for Galaxy users after using Smart Switch

What you need to know

• Samsung Galaxy users are reporting RCS issues in Google Messages after switching to a new phone with Smart Switch.
• Some affected users are seeing error code 3100 when trying to enable RCS or send messages on their new Galaxy phones.
• Google says corrupted cache files transferred through Smart Switch may be responsible for the RCS connection problems.

Samsung Galaxy users are reporting a surge in RCS issues with Google Messages after recently switching to a new device.

Samsung recently shut down its Messages app in the U.S., asking both new and existing users to switch to Google Messages instead. Google Messages is the only messaging app on Galaxy phones that supports RCS, making it the most sensible replacement. However, it seems that some Samsung users are running into problems getting RCS to work after setting up their new Galaxy devices.

As spotted by Android Authority, several users have taken to Reddit to report that RCS stops working after switching to a new Galaxy phone and transferring their data using Samsung Smart Switch. Some affected users are seeing error code 3100 when trying to enable RCS or send RCS messages from their new device.

It looks like Google has already identified a potential cause. A Google representative said that the issue may be related to corrupted cache files that were transferred during the Smart Switch process.

Google recommends updating to the latest version of Google Messages, turning off RCS, clearing the Carrier Services data, restarting the phone, and then enabling RCS again. Unfortunately, that workaround doesn't appear to be working for everyone.

Some affected users say they were only able to get RCS working again after factory resetting their Galaxy phone. Even then, there's no guarantee that a factory reset will solve the problem for everyone, making it a pretty drastic workaround to try.

There are also Reddit users reporting similar RCS issues after switching carriers. Google says those cases could instead be related to the number-porting process not being fully completed.

Either way, it seems like some Galaxy users are currently having trouble getting RCS working after switching devices or carriers. Google is aware of at least some of these reports, but for now, there doesn't appear to be one guaranteed fix that works for everyone.
