please help

Hi i own a galaxy s3 with sprint. I've only had it 2 weeks or so. I was just fiddling around and i went to my device administrators under security settings i noticed one of them was.

com.sec.sprextension.phoneinfo

I tried to deactivate it but it won't do it. Can anyone tell me what this is, how to deactivate it and if i should be worried?
