It's part of Samsung's Touchwiz that gives you a quick look at your notifications etc. Even if you abandon Touchwiz (I use Nova Launcher) it keeps on running and giving itself permission to read your notifications no matter how many times you unchecked the permission box. Isn't that nice?
That might be one of those things I disable with Package Disabler Pro from the Play Store. You can disable anything with that and it is only for Samsung devices.
Yup.. Disabling bloat has been the only reason I ever rooted a Samsung phone, never loaded a custom ROM. This solves it. If you get an OS update though, re-enable all and update, then disable again.
