why i cant find samsung account in my application manager?

[AC Question]

hello everyone, i have few issue on my galaxy j5. i recently updated my phone to android 6.0.1 and i have few issue afterthat. i want to install some new theme in theme store, but it said i must log in to my samsung account which i can find in app manager. but after i go to app manager there is NO samsung account apps and while i go to account settings there is no samsung account option.
before i update my phone, i disabled the bloatware like samsung push service, galaxy apps, hangouts, etc. can somebody help me with this? and one more, i have try to re-enable galaxy apps via app manager since i think i can log in to my samsung account there, but i cant and unfortunately, i cant re-disable that app. can someone give me perfect solution? i mean, without factory reset option

Recheck to locate "Samsung Account" In SGs7- I find it this
way: Settings >Accounts..Here appears: Google-Office and
Personal (IMAP) and +Add an Account <<This is a link
that display the rest of accts included "Samsung"

If there's an error and don't wanto perform a Factory reset..
You can make a "Reset settings" Goto Back up & reset
Tap on "Reset settings" It will reset default-Network
settings: Wi-Fi: Cell Data,.etc. Sign Up Ya!
