My android phone has 5.5gb of internal storage and I have used around 3.9. I have the rest of the apps on a SD card set as adoptable storage . Google now says it cannot display cards because of low storage space. Why is that?
Just clearing the cache didn't fix the problem. But restarting the phone afterwards solved it.
I think it is becasue of cache files go in settings>storages>cache data and clear them.
