I'm actually trying to use my SD card as internal memory on my Samsung Galaxy J5 with 6.0.1 android version. I saw some post on google and i follow this tutotial :
http://www.phonandroid.com/galaxy-s7-s7-edge-fusionner-memoire-interne-carte-sd-sans-root.html (It's in french because i'm french)
but when i try to use sm partition in adb shell nothing is happening... and my internal memory still the same. As you can see on the tutorial other people got the same bug on Samsung J5.
If someone have a solution or a way to solve it.
