Please try the below temporary Workaround and see if it works for you: Go to Settings > Notifications > App notifications > Messages. Tap Notification categories (e.g., "New messages"). From there, you may be able to enable vibration individually while keeping sound enabled for calls.
We’ll share this feedback with the development team, and we recommend you also submit it via the Samsung Members app > Support > Send feedback so it can be reviewed for future updates.
Thank you for bringing this to our attention.
