Do something related to Country Specific Code (CSC). Maybe it only let you change your CSC Every Android device from Samsung has a folder called CSC. This folder contains some XML files that keep the configuration codes for the country and carrier-based customization options. Maybe it's safe to remove if you'll never change your CSC but it needs testing and I lack time for this. (I already have plenty of other packages uninstallation to test)
