Is there a way the format a SD card for adoptable storage using Oreo version 8 Android operating system on a Samsung S7. I've tried to locate instructions but everything located on the internet gave instructions using the marshmallow operating system
I realize how frustrating this must be. Our Memory Support Team would be the best option for further troubleshooting. Please either email firstname.lastname@example.org or call 1-800-Samsung and choose option 7 for SD support. The SD support team is available M-F 9 AM - 9 PM. Also, for best performance be sure to always use a class 10 or higher SD card with your device. Older SD cards may not work as well with a newer flagship device. Older model SD cards can cause freezes, malfunctions, and it can cause your phone to reboot.
