Q: When connected SD card to my iPhone, this message shown up in Import tab, "No photos to import." How to fix this?

Hi nuthorn,

I understand you are trying to import pictures from an SD card to your iPhone, but you aren't seeing any photos to import.  The article you referenced in your post, Import photos using Apple camera adapters provides a list of requirements and troubleshooting steps.  

Which device are you using?

• Lightning to SD Card Camera Reader
• Lightning to USB 3 Camera Adapter
• Lightning to USB Camera Adapter
• iPad Camera Connection Kit, which contains both iPad Camera connector and iPad SD card reader

When you put the SD card back in your camera, are you able to see the photos?  Have you tried a different SD card?

Test with a different digital camera or SD card. 

If you can import media with a different digital camera or SD card, there might be an issue with the data on the other camera or SD card

Apple camera adapters can only import content that was captured by digital cameras. You might not be able to import content that was renamed, edited, or copied to the digital camera or SD card.

nuthorn, if you can, please reply back with some additional information after you've reviewed these troubleshooting steps.

Take care,
