There is a package called android-transfer-file or something like that in the void repos but I’m not sure if its also in the mint repos, might be worth checking, its a gui app that makes it very straightforward to transfer files. Or in last resort you can always git clone the project and use ‘make’ to build manually the app
You need the package gvfs-mtp installed, if you want to do it via file manager. Or the adb tools for cli.
But really something you could have googled 3x in the time you asked this.
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.
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
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.
