images being cropped on import

Importing images from an sd card (using apple SD card reader) results in importing photos that are cropped on both iPhone and iPads (with the newest ios).

I've tried 3 different devices and this happens with all 3, it does not happen with another manufacturer tablet.

The camera images are 4000x3000.

When I click on the image in the photo app, it appears still as the cropped image but when i tap on "edit" the full image appears and it is not saved unless I make a change and save it under editing.

What's the issue and what's the fix?
