Please do not give wrong information!
After S10 this option is not available anymore. AOD is always active, for period, on tap to show but WILL NOT turn off ONLY when is in your pocket for example.
Thank you for your feedback.
In "Always On Display" Settings, you can choose "Tap to Show" . This will turn AOD off until you need to use it.
We appreciate your contribution to the Beta Program.
