Upgraded from S4 to S8, great phone with no problems until it stopped recognizing SD card I have transferred from S4. It is showing it as 'corrupt'. I've put it again into S4, works fine. It's Kingston, so not some no name card.
A quick look at US community forums shows that Samsung has rolled out a patch to fix the issue (it appears to be a software one). I have an unlocked European version of the phone. Any hope for a software fix here?
