Please summarize here, your question ringtone is placed in the notification folder, and the SMS ringtone cannot be set or what is the default?

Hello, according to your description, since you didn't provide the specific model, taking the Android phone as an example, I suggest you try the following methods:

1. I suggest you check whether the notifications folder is under sdcard0. If not, you can try to move this folder to sdcard0.

2. I suggest you go to Settings-Apply-All-Settings-Clear Data.

3. Do you have 360 security guards, QQ mobile guards, Jinshan mobile guards and other mobile security guards installed in your mobile phone? If so, try uninstalling them.

4. It is recommended that you restore the factory settings of the machine, as follows: Setup-Reset-Restore the factory settings (however, since restoring the factory settings of this machine will lose all data in your mobile phone, it is recommended that you back up important data such as phone book, video and pictures in advance).

If the customized SMS ringtone cannot be set by the above methods, please bring the purchase invoice, maintenance card and machine to Samsung Service Center, and the engineer will check the machine.

I hope I can help you. Have a nice day!
