Importing about 400 photos takes almost half an hour. Whereas with the Photos app its less than 10 minutes.
I've heard that Lightroom does more with the photos during import than the photos app such as face detection XML sidecars geo-tagging etc. But can't all that be done after the import? Is there a way to just get the stuff off the phone/card so I can eject and continue my day while Lightroom does whatever other photo analytics it wants?
Based on the one time I let Lightroom import from my Android phone, my recommendation would be to manually transfer the images from the phone to the computer, then let LR import the images from the hard drive.
