How does the "Format as internal storage" feature work in Android 6.0+? See screenshot below:
Why is it the case that "this USB drive will only work in this device"? Is it due to a partition format? I have tried to read it in Windows but the file format is RAW; is it in EXT4 format so Windows can't read it? What will happen if I insert this card to another Android 6.0 device? Will the other device able to read it?
