Unable to activate lotus/four leaf clover default launcher


I would like to ask for the help. I just bought Lenovo S720i and I don't know how to put lotus/four leaf clover louncher on the screen. I changed few themes, but no luck in any of them. I have also Lenovo A820 and it is possible in this phone by long-press in home screen - widgets - lotus. But in S720i I cannot find "lotus" in widgets selection.

Has anyone an idea, please?

Thank you VERY MUCH in advance!!
