Why isn't S Note found after restoring a phone?

S note not found after restoring phone

My phone's battery was dying really fast and the phone itself was heating up a lot and I read in one of the posts here that restoring it helped. So I did. And now I can't find the S Note. I already looked in the galaxy essentials and the only thing with the "S Note" name is the "S Note reader" which is something completely different. And I already looked everywhere else. What can I do??
