How can I get the data off a locked smartphone?

Episode 1562 (2:07:35)

Marie from Burbank, California
Galaxy S8

Marie has a Samsung Galaxy S8 and has forgotten the password pattern to unlock it. She wants to back up her messages. Leo says that the phone store may be able to get the data off it. Even better, a third party cell phone store may be able to do it better than AT&T can. The downside is the data will be encrypted unless she can unlock the phone, and that may require resetting the phone. Check with the carrier. They may have copies of the messages.
