Question

Android

My wife samsung duos gt-s7562 She always
lacks memory. I took a look, I see in the settings that the flash drive is visible, but it is empty. Those. all 7.53 GB out of 7.53 GB are free, the phone continues to use only internal memory, why? Formatted the flash drive, still the same problem. How to make it so that it saves files to flash? At least photos. There is nothing like that in the camera settings.
