Android Tablet won't sync to SD card
I have an Android tablet with KitKat 4.4.4 and I can't upgrade to any later versions. Can anyone direct me on how to sync to my SD card? I do have root access, but no move app to SD card with, or with out root has helped, and I'm officially stumped. If it matters, it's an Acer B1-810 tablet with a 128GB SD card.
