Method of setting SMS ringtone in Samsung S8;

Mode 1. Information-More-Settings-Notification-Slide on -SIM 1/SIM2- Prompt tone (default notification tone/mute/built-in ringtone)

Method two. Customize the SMS ringtone, save the song to the Notifications folder in the root directory (if not, please create a new one), and then set it according to the above path.

If the built-in ringtone of the mobile phone system is lost, we recommend that you do the following:

1. Reset application preferences.

2. Back up the data in the mobile phone (contacts, information, photos, etc.). ) and try to restore the phone to the factory settings.

3. If it doesn't work, it is recommended that you take the purchase invoice, three-guarantee certificate and mobile phone to the local Samsung service center for inspection by engineers.
