To change your ringtone to a song on an Android phone, first ensure the desired song is downloaded to your device as an audio file (e.g., MP3). Then, open your phone's Settings app, navigate to "Sound & vibration" (or similar), and tap on "Phone ringtone." You'll typically find an option to "Add" or a "+" icon that allows you to browse your phone's storage and select your downloaded song. Once selected, confirm your choice to set it as your new ringtone.
