I recently ran an scan on my phone using MVISION, the scan indicated that com.pivotmobile.android.metrics was sideloaded and that it should be deleted. I could not find any valuable information of its origin on the web, but looking at the application tab on my phone setting, I could find out that it was installed by Claro, my mobile service provider. So I went ahead and deleted, without a problem Take this with a little caution (backup before deleting, bla, bla, bla), but it looks to be a mobile service provider tracking file.
Just a collection of the solutions I have found to my life problems (Technical problems only, sorry)
