The camera settings only save it to the phone or the internal virtual SD card. I have installed a 32 bit hispeed SD card. How can you force it to save in the external SD card?
It varies from phone to phone, but generally in your camera settings you can set a destination. If that's not an option, you can try something more creative with an app such as tasker to have it automatically move pictures that your camera adds to its folder to a different folder on the SD card. If your stock camera app doesn't let you though, there are solid camera apps on the play store that certainly do.
