The SD card is back in the S7. Here's how you can protect the data on it.

Samsung listened to its customer-base and brought back the option to add an SD card with the S7. If you're worried about the security of the information stored on your SD card, you have the option of encrypting it. However, you should be aware that you can lock yourself out of your own SD card if you forget your password, PIN, or pattern, or you can't power on your phone.

This article only refers to how to encrypt the SD card, not the data on the device's storage.
