I understand you have to root the tablet or otherwise do some work to move stuff to the external card but if you fill up the internal memory does the tablet start using the external memory automatically? If not then what is the use of the external card? Can I at least specify where my photos and videos get stored? It just seems really stupid to not have a way to specify which memory to use. Even an app like double twist that supposedly allows you to choose external memory did not work, it just put all my music on the internal memory.
