sorry for my english (by Google Translate)
With Google KitKat has favored the use of internal memory and has imposed on the sd card read-only mode.
I've done several tests and I could see that LG has allowed the writing from the File Manger, USB and the camera (what I've tried so far).
The connection "Archiving Wireless" allows read-only memory microSD.
I wanted to know if there is a way to write anchge.
