When you used it on the different device, it may have been changed by the new device. Especially it being a different OS. The only way around it would be to place it back in the device it was in, send whatever files are on it through that device to a cloud account, google account or a computer. Then place the card in the device you want to use it in now, format it (clearing it off) and then download or move the files you saved back over to the phone and card.
