I copy photos and videos off my phone all the time; it’s far more convenient than trying to send it over the internet. But even the “slow” speed of 480Mbps that they’re complaining about seems more than adequate; copying a few gigs of photos will only take a minute or two, and even copying my phone’s entire 128GB of storage would only take 35 minutes. Compared to most USB storage devices that’s blazingly fast.
My best guess is they somehow mixed up minutes and seconds? Usually people mix up bits and bytes the other way and overestimate speeds.
