How to remove read only property from micro SD card (Samsung S7)

[AC Question]

Samsung 64 GB EVO micro SD card on Samsung S7 is read only. Excel and Word files cannot be modified.

The only way is to save to another location and then save onto the micro SD card again.

I have a Samsung 32 GB EVO in my Galaxy Tab A 9.7 and all of my Excel and Word files are read only. So is this an issue with the Samsung card? If I purchased a different brand card, say ScanDisk, would that eliminate the problem?
