Using a Hard drive with iPhone 11
How can you setup a external hard drive on an iPhone 11?
iPhone 11, iOS 17
if connected to the lighting to usb connector and the hd is self ac powered or connected to a powered USB hub it should be able to import photos from the hd in the same way you would a digital cam or sd card
but it will not let you install apps on the hd and run them as you would if installed on the internal storage of your ios device
