There was incorrect information on Amazon.com that stated that the THETA V has a MicroSD Card. This is incorrect. The THETA V does not have a MicroSD Card.
In addition, I heard that unlike the THETA S, hardware-hacker enthusiasts can’t access the THETA V storage. There is no way to change the MicroSD Card even if you disassemble the THETA V. As far as I know, there is no card inside the THETA V.
