Why you should (or shouldn’t) encrypt your SD card.
This is easy to answer. If you don’t want someone who isn’t you, but has access to your phone, to be able to pull the SD card and put it in another computer to see what’s on it, you need to encrypt it. Head into your GS7’s settings and find the Lock screen and security menu to do it. encrypt your SD card
But encrypting an SD card also has a drawback — you can’t ever read the contents in another device. That means if you break your phone while the SD card was encrypted, everything on it is gone. Because of the way encryption works, even using the same password on a different phone of the same model doesn’t give you access.
Outside of the phone you originally used to encrypt your card, your only option to ever use the card again is to erase it and start fresh. If you’re storing things like confidential business documents on your SD card, this is a good thing. If you’re using the card to keep memories from your camera, this isn’t such a good thing. You’ll need to decide if what you store on the card is important enough to lose forever if it falls out of your hands, or important enough that you don’t want to lose it when or if your phone breaks.
You’ll need to think and decide for yourself whether or not to encrypt your SD card. There is no wrong answer.
