I have a Samsung Galaxy S7 and am trying to change my SD card to adoptable storage. I am using ADB and get the disk:179,0 address, but the real issue is when I do the partition, it returns immediately and doesn't create the partition. I have developer turned on, but under USB Configuration I don't get Software Transfer choice. All I get is Charging, MTP, PTP, RNDIS, Audio Source and MIDI options. What could be wrong? I am baffled as to what is happening. Someone please help. USB debugging is on.
