This might be obvious but when you connect your phone to your PC have you enabled file transfers? Usually it defaults to charging only. It should show up in your notification bar.
I’d use Kdeconnect or syncthing
syncthing doesnt use usb sadly
This is the way. MTP is horrible and adb is annoying.
MTP sucks, it’s even slower than good WiFi and half the time it locks up in the middle of a transfer.
fun tip, if you have a samba share and your devices are in the same network, use a file manager that can connect to local network (like explorer by speed software), and transfer your files wirelessly. it seems to be equally fast too, i haven’t used a cable for ages except for killing updaters and bloatware with adb.
Plug in cable to PC, go into android USB setting and switch it to file transfer instead of charging mode, it should show in your file manager as a connected USB drive. ( you can tell everyone is a linux or phone techy, everone gave the complicated merhods that didn’t address the question asked, but @OP all the other methods work also )
Plug it in, unlock it, tap the USB notification and change it to “transfer files”. I like to keep my screen on but you shouldn’t have to.
search usb in settings, set it to file transfer while its plugged into your pc. Alternatively you can install kde connect on both of the devices and transfer files wirelessly
Mtp is your friend, here is hiw I do it on my devices (samsung a23 and both opensuse and arch):
-
I connect my phone to my pc. Then select mtp in the phone notification.
-
Start my file manager (dolphine or whatever) and access my phone storage from there.
-
Make sure to allow the notification on the phone asking if you want to sahre your storage with the external device.
