My Samsung Galaxy S7 Edge had a software update on 4.21.18, and since I was not on WiFi, the update did not process until 4.22.18. When I restarted my phone, my phone said that the SD card was corrupted. I plugged the card into my computer, and transferred all of the files to a flash drive. All files except for one transferred over. When I put the SD card back into the phone and tried reformatting the card, my phone says that it cannot read the card and that it is still corrupted. I have rebooted the phone a few times and reformatted the card, but it still isn't fixing the issue. Also, there has not been any damage to the phone (e.g. dropping the phone) that would most likely cause a hardware issue. Any idea what is going on here?
