I want to delete the app right now from my LG G3 phone, but don't want to lose my songs. How do I save them to my memory library?
Firstly, locate the content on your phone and use the built-in File manager to move the media to another place. After you have done this, simply uninstall the application from your phone and that's it.
To find things easier, install ES File Explorer from the Play Store: https://play.google.com/store/apps/details?id=com.estrongs.android.pop&hl=en
You can use search to locate the files easily.
