How do I open and clear recently used apps
Select one of the arrows visible at either side of your home screen.
This opens the LUX menu at the side chosen. From here, select the ‘Active’ icon.
This opens a menu that shows all the apps currently running on your system. These can be individually closed by swiping one at a time. Alternatively, selecting the ‘Clean All the Processes’ button will bulk close all active processes.
