Samsung's mobile phone message reminds you not to move and keeps ringing.

First, if there are unread short messages on the mobile phone, it will repeatedly ring the prompt tone within the specified time interval. This is because the mobile phone has turned on the function of reminding unread messages repeatedly.

Second, the cancellation method is as follows:

Enter the message-menu key in the lower left corner-Settings-(More)-Check the notification-Select the message repetition tone-Select Never.
