If you go to settings and search for the word TRUSTED it does not show "trusted places" or "trusted devices"... you have to try and find this my trial and error and browsing through dozens of settings.
And as a side issue once you have set these places and devices the extended unlock does not work very well at all.
Within extended unlock there are trusted devices and trusted places, so they should be things that you can search for and find! but you cannot using the Samsung settings app.
