Oppo system comes with classic ringtones.

I want to change my ringtone and my mood today. The method is simple:

1, enter "Settings >"; Sound and vibration >: ringtone, you can select the system ringtone, or click "Select from file" and "Online ringtone" to customize the ringtone.

2. When a dual-card mobile phone is inserted into a dual card, you can select the corresponding SIM to set the ringtone: enter Settings > Sound and Vibration >: select the corresponding SIM card and ringtone to set it.

Tips:

After upgrading to the system version of ColorOS 5.2. 1, the ringing tone of the incoming call changes from small to large, and it is the default of the system and cannot be changed manually.
