I recently upgraded to 6.0.1 Marshmallow on my Galaxy S5 and I would like to adopt an SD card as internal storage. However, there is no option to do this.
When I format the SD card, there is no "Internal" option, only a "Portable" option.
I am using this SD card:
I have tried formatting the SD card in windows, deleting the partition in windows, and even wiping the parition in windows. But Android always wants to add it was portable storage.
How can I force Android to add this as internal storage?
EDIT: According to this article, the Galaxy S7 doesn't support adoptable storage. So it's likely the S5 doesn't support adoptable storage either. I'm looking for a way to enable it using the adb command line if possible now.
