Scammers are a real problem, and it's important to take steps to protect yourself from them. One way to do this is to adjust your privacy and security settings on your phone. In the Settings menu, select Privacy and Security, then Calls and Groups. Under Calls, select Who can call me, and choose either My Contacts or Nobody. Under Groups, select Who can add me to group chats, and again choose either My Contacts or Nobody. This will help to protect you from scammers, as you will only be receiving calls and messages from people you know. Additionally, be sure to be wary of any suspicious messages, calls, or emails, and never give out personal information to someone you don't know.
