I tried a new 64gb sdxc and sdhc and they both had the same issue. every time i want to transfer and high res pic or vid from the device to sd storage it shows the broken icon in the gallery, and even if i set it to automatically save to sd card same thing happens. 8gb and 16gb works fine.The card saves other things but not high res stuff. Ive tried the format in the phones settings already and no it still doesnt work. any help???
