TL;DRSome Google Messages users are facing RCS connection issues, particularly on Samsung Galaxy devices.The issue seems to occur only after using the Smart Switch app, with Google saying it may be caused by corrupted cache files.While multiple remedies are currently floating around, not all of them appear to be effective.One of the biggest draws of the Google Messages app is RCS messaging, an upgraded version of SMS that adds features like encryption, read receipts, and media support. So it’s no surprise that it’s the preferred method of communication for most people. It now looks like some are facing trouble connecting to RCS in the app.In a thread on Reddit, a user describes switching over from a Samsung Galaxy Z Fold 6 to the Galaxy Z Fold 8 and being unable to connect to RCS, reportedly seeing the error code 3100. A Google rep has since chimed in with a potential remedy, while hinting that this may be due to corrupted cache files that could have snuck through while switching devices via Samsung’s Smart Switch app.
