Having really annoying issues with my wife's S4 and the SD Card.
Have a class 10 32gb SD Card fitted. Used to work find until Samsung rolled out loads of updates. Now when taking photos/videos that is saving to the SD card they are corrupting straight away, So I took the SD card out and copied all the usable photos over to a external HDD to have a back up. formatted the SD card and transferred the non corrupted photos back to the card and re-inserted into the phone.
Looked in the gallery and there was double the photos that were corrupted.
Any ideas why the phone is doing this? Does the SD cars need to be formatted to FAT32 or NTFS?
Is using a Samsung on better?
