My Xperia X with Sailfish is running - I really love it! But I have a problem: I have a 128gb micro sdxc card and it is not recognized by Sailfish (Settings=>Storage: "Memory card not inserted"). I tried ext4, fat32 and exFat (formatted outside the smartphone), and I also inserted the card without formating it. The result in Sailfish is the same: "Memory card not inserted". Do I make a mistake?
Maybe remove and recreate partition table on your sd card ?
