My old moto/android 4 phone, I plugged into my PC via usb and it showed as a disk or device and I could move files normally. My new moto x4 and android 9 I find that was turned off. Didn't even offer "you've plugged in, did you want to enable xfer?" Nope. Dead silence on both ends. I had to dig deep to find where to turn it on. It warned about "only connect to trusted devices" like maybe the reason to have the default off was safety. I'm guessing this means most people don't transfer files by usb anymore (even those of us using PCs). Probably some other method has become more typical. Like emailing them to yourself or friends (ridiculous). Or texting them or an NFC exchange (well, not to my pc). So what is the more common method? Or is this just a nonsensical way to set defaults?
