So it's SAFE to move to sd apps not included into the rom. If you want to move an app that come perinstalled in your rom onto your sd card with Titanium Backup you need to uninstall the app you want to move or make the app a normal apk not included into the rom on your sd from the rom itself, reinstall it as a normal .apk if you unistalled it and than move it to sd card. That'all folks
I'll write a little and more detailed guide if you think it's useful
O.P. Is safe to freez samsungapps.apk and samsungappsUNA.apk?
