usb storage app

[pmheart6]

I see people taking about usbstorage as there internal sd card. It seems to me that on the Kyocera torque, its using internal storage. And its doing so as a system app.


I show 3 pieces of storage :

Internal (apps only - yet it seems it really includes data including data for apps on the external card)

Phone sd
External sd


It seems a lot of apps are saving data to usb storage app. I have the default storage as external sd. The apps saving to usp storage app Include apps on the phone and those moved to external sd.

I delete these apps and space magically appears un internal memory.

How can I make these apps either use there local memory, or make the usb storage app use the external card.

Its not really flexible.

This may be relevant. From the Android Developer reference on App Install Location.

When your application is installed on the external storage:

• There is no effect on the application performance so long as the external storage is mounted on the device.
• The .apk file is saved on the external storage, but all private user data, databases, optimized .dex files, and extracted native code are saved on the internal device memory.
• The unique container in which your application is stored is encrypted with a randomly generated key that can be decrypted only by the device that originally installed it. Thus, an application installed on an SD card works for only one device.
• The user can move your application to the internal storage through the system settings.
