Expandable storage was the other major feature abandoned on last year’s S6. The S7 brings storage back and supports microSD cards up to 200GB. That’s all thanks to its hybrid SIM tray—it squeezes a microSD card slot into the SIM tray. Yet Samsung’s only half-committed to integrating microSD into the S7. The company left out a key feature from the latest version of Android.
Flex Storage, also known as adaptable storage, allows Android devices to treat external SD cards like built-in storage. That means you can hold more than photos and videos on the card itself, and it encrypts the SD card and links it to the specific device, so it’s much more secure.
