I'm using a Meizu M6, and a newly bought Sandisk Ultra micro SD XC 64gb. Internal storage is about 1.67 gb free out of 16gb.
For the record, I have already checked the wiki tags and similar topics, as well as format, remount, cache clear, and/or reboot, but none of them worked.
So my phone and desktop can detect my SD, but:
everytime I tried to create an empty, new folder on my SD, it gave me the "insufficient storage space" message... despite being empty as a clean slate.
everytime I tried to use the camera, it gave me the "insert SD card" message... despite being able to detect it earlier.
Yet I can create new folders and move items to my SD if I connect it to my PC with some card reader.
What might caused this? Any pointers?
