How do I turn master sync back on Galaxy S5?

Go to HOME screen, swipe down from top to reveal actions and click on SETTINGS WHEEL in upper right corner. Under settings click on ACCOUNTS under Personal and your accounts should be displayed. Click on MORE (3 vertical dots) in the top right and "Turn on auto sync" should be displayed.
