I would like to turn off multiple desktops that are on my Android 4 phone (LG Optimus L9 P760, if that matters). I can switch between them with touch, but I don't need that feature. And most of the time, I use it by mistake (when I want to click an icon close to screen's edge). So it's more like disadvantage for me to have multiple desktops.
Unfortunately, I cannot find any such position in top menu, settings menu etc.
