It's labeled as "Mobile Services Manager" under Settings > Apps (it does not appear in your app drawer in your launcher).
Previously called DT Ignite (or just Ignite), it can and does install apps without your permission as instructed by your carrier. This is in addition to the apps installed on first boot by ConfigAPK (android.autoinstalls.config.samsung) and is guaranteed to just be bloat.
The package name is com.LogiaGroup.LogiaDeck and was found on my device under /system/carrier/priv-app/IgniteVerizon/IgniteVerizon.apk. Without root, you can't delete this package, but you can disable it, which will prevent it from continuing to do its dirty work.
