I was gifted a Lenovo A1 with 2 GB if internal memory. It is known as the internal SD card. I put in a 16 GB card that is known by the device as the external SD card. Is there a way to manage between the internal mem, internal SD and external SD? The device only give a choice between internal memory (Tablet) and internal SD. Is there a great Android App for this? Any help would be appreciated.
