Adoptable storage was a feature first made available with Android 6.0 Marshmallow OS back in 2015. It allowed Android phone users to use the external storage of the smartphone for not only storing media and documents, but also for using it to store apps. Among the well-known smartphone brands, Samsung is the only firm that has never provided this feature to its users. Until now that is.
Screenshots of the leaked builds of Android 9 Pie OS for Samsung phones that have surfaced on XDA Developers forums have revealed that it will be soon rolling out adoptable storage feature through the Android 9 update. The probable reason why Samsung did not make adoptable storage feature available for its phones is that it was only meant for low-end devices with less storage. The Android 9 Pie update arriving for the Galaxy Note 9, Galaxy S9+ and Galaxy S9 are expected to include support for adoptable storage.
Even though the leaked beta build contains adoptable storage function, it does not work properly. The feature could be fixed before the Android 9 Pie update officially arrives on Samsung smartphones. Samsung has delayed bringing the said feature to its smartphones as most of its Android devices are equipped with sufficient 32GB of internal storage. Only phones with less storage such as Galaxy J2 Core and Galaxy J2 (2017) will benefit from the adoptable storage feature.

The Android 9 Pie update for Samsung phones will bring along the new One UI skin. The Galaxy S9 series and Galaxy Note 9 are expected to be the first Samsung smartphones to receive the Android 9 update in January 2019. The South Korean tech giant is reportedly working on One UI flavored Android 9 Pie update for Galaxy S8, Galaxy S8+ and Galaxy Note 8. There is a possibility that phones will be treated with the final version of Android 9 by the end of Q1 or in Q2 2019
