Welcome to Android Central! What kinds of things? What Android version is your phone running? KitKat put some restrictions on what the device can do with an SD card, so the ability for an app to save to SD has to be part of its code, and it needs that specific permission. If an app doesn't have SD permission, then it can't save to SD, nor can it read from SD.

You can always use MyFiles or a 3rd party file manager app to copy or move files from the Internal Storage to the SD card and vice versa. The Camera ought to have an option to save directly to SD.

Some (but not all) devices allow you to "move" an app to the SD card, but this is a bit misleading, because it's only moving a portion of the app--most of it needs to remain in Internal Storage to function properly. To move the app, go to the App Manager, select the app, and tap "Move to SD." If that button is not present or greyed out, then it's not possible.
