Samsung S4 mobile phone SD card can't be used (there is a display, but you can't copy and paste files, etc. ), but the card can be used normally with the card reader. How to solve it?

Hello:

According to what you described, I suggest you try to move the file again:

My Files-Select Folder-Long press to move the folder to sd memory card.

If it can't be moved, I suggest you check whether the file is bound to the mobile phone. Files bound to mobile phones do not support moving.

Wish you a happy life!
