I have about 15 gig of MP3's I would like to get onto my 'phone. How do I do this without subscribing to Google Play? I don't want to spend £10 for a service I don't want. I tried plugging it into my PC (USB) in the hope that it would come up as removable media and I could copy them into the music folder on the phone. No joy; I can't even find a file manager on the phone....
Any way of doing this?
