New update everytime I restart my Samsung Galaxy S6

[Android Central Question]

So a Galaxy S6 that has been running Android 6.0.1 since it had been bought brand new, Now on it's 3rd year.... The 7.0 update ( Nougat ) finally shows available... Gets Downloaded, Phone restarts, And every time it restarts it says
" System Update Available " ……

Welcome to Android Central! Does the build number change at all after it seems to finish the update?
