Does Galaxy A8+ 2018 Support the Adoptable Storage Feature?
No, Galaxy A8+ 2018 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 can not guarantee the system stability and protection of data files.
