For peoples asked to move Phono to sd:
Direct from android dev documentation
Applications That Should NOT Install on External Storage
When the user enables USB mass storage to share files with their computer (or otherwise unmounts or removes the external storage), any application installed on the external storage and currently running is killed. The system effectively becomes unaware of the application until mass storage is disabled and the external storage is remounted on the device. Besides killing the application and making it unavailable to the user, this can break some types of applications in a more serious way. In order for your application to consistently behave as expected, you should not allow your application to be installed on the external storage if it uses any of the following features, due to the cited consequences when the external storage is unmounted:
Your App Widget will be removed from the home screen. When external storage is remounted, your App Widget will not be available for the user to select until the system resets the home application (usually not until a system reboot).
Like developer we think to give to the user a stable application! That's the main reason we do not raccoment to move Phono on sd.
You give us one star cause we don't allow to move Phono on sd, before to be so categorical you could write us a mail and ask the reason about our decision.....or to read the documentation......
