Totally agree with @Epix4G
on this one. I am assuming you had a korean variant? The SK Telecom stock image is pretty ugly. Took me 3 debloat attempts before I had it behaving the way I wanted it to, but before I debloated, I had some lag issues (SK Telecom... grrrhhh).
Historically, Korean carriers (much like AT&T and Verizon) love putting useless junk on the phones for "productivity" but really they are there to charge Korean users more for other services, etc.
If you haven't done so, I would root and debloat, and see how big of a difference it makes (absolutely amazing performance after debloating on my F400S).
