Nubian z 1 1 How to change the system prompt sound has been root.

Now Nubian z 1 1 system has supported the choice of your own local music as ringtone. You can select local music in Settings-Sound and Vibration, and click ringtone settings, as shown below. For users with root privileges, you can download third-party software, such as many ringtones. After giving the software permission, you can add the ringtone you like in the software to the system ringtone settings. I suggest going to official website, Nubia for more information.
