My wife has a Samsung Galaxy S9 with Android 10 on it. It has an SD card which has about 11 free GB, and the phone’s internal storage has only 400 free MB or so.
I have two questions concerning photos/videos and storage:
- The phone’s camera is configured to store photos and videos in the SD card. However, we’ve found it arbitrarily stores them in the internal storage or in the SD card rather than respecting the setting. Why could this be happening?
- When we tried to move a photo from the internal storage to the SD card (by going to Gallery, selecting the photo, tapping the three dots at the top-right corner and tapping “Move to folder”), it says there isn’t enough storage in the phone before even asking where the photo should be moved. This happens with all photos in the “Camera” folder in the internal storage, whether or not they’re uploaded to the cloud. It isn't a memory (RAM) issue (unless I'm mistaken as to how virtual memory works), because even if all of the phone's real memory were used up and the phone had to create virtual memory, the size of the required virtual memory would be equal to the size of the file(s) we're trying to move, and 400 MB is much greater than the size of one photo. (Not a duplicate of this question, which is about moving apps to an SD card.)
We’ve tried unmounting and remounting the SD card, but that doesn’t solve either of the problems.
Edit: Added a note on why I don't think memory has anything to do with problem 2.
