Richard wants to know if moving apps to the SD card will save space. Leo says it can, if he knows how to do it. It's not really easy. Google does have a workaround, through adopted memory, but Leo says it doesn't work very well, depending on what phone he uses. Even if he can do it to save space, he's not saving that much space. The biggest storage hog is data. So why not move the data to the SD card and then keep the app on the phone's internal memory? It's one of the reasons why Apple and Google don't use SD cards.
