The most exciting news of the day has to be the fact that Samsung actually left Adoptable storage in touchwiz. The feature is not easily accessed however, and is not at all apparent. Samsung believed that their users would rather have a removable sdcard that they could store photos on and share between devices easily. With adoptable storage your sdcard is formatted and is used as internal storage so you can't just go willy nilly removing it from your phone and sticking it into other devices. Samsung does allow you to store apps on the SDcard, but this is not the same as adoptable storage. "PaulOBrien" did some deep digging and found a way to get adoptable storage working on the S7 and S7 edge! All you have to do is type a few commands in ADB and you are good to go. You don't even need root! Head to the link below for full instructions.
