Heads up: When you upgrade from a current Advanced Messaging smartphone to a new smartphone featuring Messages by Google:

• We suggest you use Samsung Smart Switch to move messages from your current Samsung device to your new one if you don’t choose Copy apps & data. Smart Switch is in the app section in the Samsung folder.
• You can copy text, picture, multimedia, and RCS messages from your old Samsung device to your new one.
• You should know that AT&T Messages Backup & Sync (AMBS) isn’t compatible with Messages by Google.
