Earlier quoted context omitted.
plug in USB cable, drag and drop entire directory from one drive to another with file explorer, is the only reasonable way to manage photos. Get everything off the device at the end of each day. Why would you ever put things back on the phone?
And then if I want to look at my photos while I'm out, or show them to someone, I don't have them on my phone anymore?
Being forced to upgrade phones... Ugh.
I don't have a solution if you're not me and you're not paying me, though.
