It’s always worth remembering that Linux is not a product, it is free software. So if you are switching you can’t go into it with the mindset of “somebody better fix this or I’m leaving” because there is nobody that will feel that pressure or care. You have to use Linux because it’s something you want to do.
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.
