System Sound Changer [root]

按下时更改默认的系统声音，如“嘀”的声音。

This is an app that I created that allows you to customize the way that your device sounds. You can change all of the system sounds in this app without having to do it manually. This app will work with all devices where the system sounds are stored in the /system/media/audio/ui/ directory.

How to use:

To use this app, all you have to do is download a sound that you'd like to use, browse for the file that you downloaded, select the sound that you'd like to change, press the "apply" button, and, when prompted, press "yes" to reboot.

How to revert:

To revert back to the original sound, simply select which sound you'd like to revert back, and then press the "revert" button.
