I have an 'el cheapo, ID716WTA from CyberUS. When I look at storage, I have 2 'Internal Storage' areas listed, one with .98Gb, and the second with 4.32Gb. Both have apps and data out of the box. If I insert a Micro SD card with 4Gb, it doesn't show up. With SDCard Manager, if I look at /mnt/sdcard there is data, so I'm thinking the 2nd internal storage is listed as sdcard. (In fact, in settings - storage, 'Erase SD card' clears the 2nd internal storage.) How do I set this up to accept another SD card?
