If you can’t do that, that’s a manufacturer restriction. I’ve never had a phone that couldn’t do that and my current one is only last year’s model. I plug it in, it gives me a few options: charge, usb storage, i think something else also, and it works like it always has. I assume the OS files and some app files are protected but everything else is drag and drop as if it was any other storage device like it has been since my first Android in 2010.
