On my last OS upgrade, my Samsung Note 4 has not worked properly anymore, is there a fix to this?

[AC Question]

Since I updated my phone the apps on my phone are gone Haywire. For instance my clock on the sleep screen stops giving the right time, my notifications on any apps remain on the app icon, when I try to open certain apps it kicks me out unto the homescreen, my alarm does not alarm me anymore. Please help
