If I either connect my Camera using a USB cable via OTG or inserting the SD card in a OTG reader connected to the phone Android creates automatically two folders: an Android folder an a Lost.Dir folder.
The problem is that as long as these two folders are on the camera (a Pentax K50), this latter thinks that the SD is not properly formatted and asks me if I want to format it or otherwise I cannot use it again. And indeed if I delete the two folders using my PC I can then start using the card again. Obviously I cannot format it.
The problem is that I cannot delete these folders on the phone without reliably preventing android from recreating them. Also the two folders remain on the SD even if I properly eject the OTG storage.
The problem is that I am going on a trip and I won't be having a pc with me. How can I then transfer the photos from my camera to the smartphone?
