Can Lumia 920 customize ringtones?

Say the answer first, then the method.

You can customize some ringtones, upload your own MP3, or set them through the app. For short messages, "you can't customize", you can only choose from several preset sounds from the original factory (in fact, this is also called customization), but you can't upload new music as a short message ringtone.

Sending ringtones is very simple, just plug in a usb, just like a USB flash drive, and then copy the ringtones into the ringtone directory and customize them in your mobile phone.

It's much simpler than other mobile phones.

And now there is app software on the mobile phone to support directly turning mobile music into ringtones, which is Nokia's own software.
