Default [Q] SD card become read only

I am using Samsung 64G with FAT32 formatting, it's very normal before. But I found it will become read only mode now and need to reboot mobile everytime. Unfortunately, same problem occur again after few days and need to reboot again.
I just wondering it's device or SD card issue? Thanks!

I can use it in computer, and as the problem didn't occur immediately, so it's hard to test with other device.

I had a similar problem with my SanDisk 64GB. Unfortunately, the thing was borked. I could still read from it, but couldn't write anything to it. These symptoms appeared on both the phone and computers (via SD adapter and via phone's USB).

Just sharing my experience.

Well, the sd card is long gone now. But no, I wasn't able to. I would be able to move files onto it, via a file browser, but it would disappear on reboot or if I stuck the SD card into a computer. Which meant that nothing was written to the card itself.

i think it's the device issue. because you saying the problem didn"t occur immediately. if the SDcard issue you most see it read only in PC. and whats you android version in your device? if 4.1.2 you most change it to 4.2.2 or 4.3 because 4.1.2 don't support 64GB SDcards
