Samsung mobile phone SMS ringtone

According to your description, since the specific model of the mobile phone is not provided, taking an Android phone as an example, if the built-in SMS ringtone disappears, I suggest you try the following operations:

1. It is recommended that you reset the SMS ringtone: Info-Menu Key-Settings-Select Sound.

2. Do you have mobile phone security guard software or some third-party software programs installed in your mobile phone? If so, try uninstalling it. Settings-Applications-Open the application to uninstall-Uninstall.

3. If this situation still exists, it is recommended that you restore the factory settings of the machine according to the following steps: Setup-Reset-Restore the factory settings (however, since the machine will lose all data in the mobile phone when restoring the factory settings, it is recommended that you back up important data such as phone books, videos and pictures in advance).

If there are still problems through the above methods, it is recommended that you bring the purchase invoice, maintenance card and mobile phone to Samsung Service Center for inspection. To view the local maintenance center, please link to the following website:
