Bought PadFone x. from Wal-Mart in April. It sees my 16GB and 32gb sd, yet won't directly save or use. stuck at 8g have to keep deleting for space. How can it use sd card space or is this how it works. I'm use to phones letting me save music and photos to the sd. I have to copy and paste if I want to reserve through file manager or delete for phone... I like for the tablet set up just sucks. I have multiple sclerosis and doing all this extra makes the phone limited. Also many apps I can't install says doesn't have tablet version yet never issues installing on my other devices as long as android. Even when just using phone still won't let me install like credit karma..have to Use browser or laptop
