[Galaxy S8/S8+] Does Galaxy S8/S8+ support the Adoptable Storage feature?
No, Galaxy S8/S8+ does not support Adoptable Storage feature.
Mainly, Adoptable Storage is the technology applied to devices with low internal memory
capacity due to technology constraints or price issues. (If you want to use it as internal memory, you
need to format micro SD and encrypt it).
However, Adoptable Storage is not suitable for usage that external memory can be easily
attached/detached because it cannot guarantee the system stability and protection of data files.
