It seems that this package is a kind of spyware. Very difficult to find information about this.
Some people say it’s linked to Carrier IQ (which is a carrier rootkit for the NSA).
This package also have very stranges permissions: READ_PLACE / WRITE_PLACE. I couldn’t find any explaination on the web.
So either it’s a useless samsung package or a spyware. I deleted it and I didn’t notice anything bad.
