how to set default ringtone?

[Sinansinu]

Can you help me to set back the default ringtone in m31 without Sound Picker option, please.

Just go to settings and select sound and vibration then ringtone and select sim 1 and if you use sim 2 then also select it and select the tone which you want to set

create folder with name Ringtones. All music files in that folder will show up while setting ringtone.
Refer screen shot.
