No auto rotate option in S6 lite tablet

[Avis6tab]

i do not have any option to setup auto rotation in my new samsung s6 lite tablet after os updated to 2.1 one ui. It gives me a small icon when I try to rotate the screen and when I press that it stays in landscape or portrait mode. I have to press this icon again and again in order to change the modes. How can I setup auto rotation. Please help me. I need this autorotation.

When you drag down the notification panel you should see 'Portrait'. Tap this until it says Auto Rotate.

Super confusing. I saw the Landscape button so assumed this was to lock the screen to Lanscape and continued to search for auto-rotate. Just leave it as an auto-rotate buttong with highlight or not. This is the normal fornmat for everyone!
