What is `/system/app/AutomationTest_JBUP.apk`?
According to this thread from Xda-developers, AutomationTest_JBUP.apk is listed among the apps that can safely be removed from a Samsung Galaxy S2. That will mean it comes installed by the manufacturer as default app.

Its package name is com.sec.android.app.DataCreate and analysis of a subsequent version shows that it is from Samsung. I have no idea of its purpose.
