Samsung always supports the micro SD card support on all Galaxy S and Galaxy Note phones except on Galaxy S6 and Galaxy Note 5. Galaxy S20 can support a micro SD card up to 1TB.
But the support of the micro SD card on Galaxy S20 is different from that in stock Android.
This Galaxy S20 guide explains the supported micro SD card features on Galaxy S20, the requirements of using a micro SD card, how to add and manage the SD card, how to move apps to the micro SD card and how to mount and unmount the SD card on Galaxy S20, and how to choose an SD card for Galaxy S20.
In this guide, Galaxy S20 refers to Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra.
Does Galaxy S20 support adoptable storage so that I can use the micro SD card as internal storage?
No, Galaxy S20 does not support the adoptable storage. But Galaxy S20 does support moving apps to the micro SD card.
Since Android Marshmallow (Android 6), Google introduced the adoptable storage to let you use the micro SD card as internal storage. It essentially increases the internal storage capacity at a far lower price.
Of course, due to performance limitations of the micro SD card, most flagship Android phones do not support the adoptable storage. Some, for example, Google Pixel phones, do not have a micro SD card slot at all. The adoptable storage support can be found in many middle-range and budget Android phones.
The other option is to use the micro SD card as portable storage, where you can save your own files, for example, your music or media collections. Apps can also request to access the portable storage to download and save large files. The “flagship” (usually means expensive and overpriced) Android phones with a micro SD card support, often only support the portable storage.
Unlike other Android vendors, Samsung chose a proprietory way to support micro SD card. It is somewhere between adoptable storage and portable storage.
- You cannot format the micro SD card as the internal storage on Galaxy S20.
- But you can move most apps to the micro SD card if you want.
Actually, this is a better implementation than the adoptable or portable storage, because
- The micro SD card is portable. You can share the media files on the SD card on any
