Hello dear friends:(
Digging into the site, I found several threads on how to move resources to an external memory card, but it seems Logos doesn't care the theme. Is there anything new about it? It is annoying having to download the resources again and again. (having issues with company phone). (Actually 3 times this week
). I found a thread with a complicated instructions, but I didn't dare. Root your phone, risk of flash all data, etc. 
Regards.
Note: Using Samsung Note 2.
