Oh wow I'll try thisJust download the Google Photos app and it'll upload all your photos. When it's finished select clean-up and it'll delete them from your phone. From then on it'll automatically upload new photos, you just need to do clean-up every so often. I usually prefer an Apple solution (which I use for music and mail) but I find iCloud Photo Library a bit clunky and difficult to share. Google Photos is the dog's bollocks, especially the Collage and Assistant.
Having used a 6+ and 7+ iPhone I took the gamble on an X because I wanted Face ID - which is brilliant. I find the screen to phone size ratio excellent for pockets and I'm 100% happy with the X.
I didn't mind paying for the extra iCloud storage since its cheap but if this way is better then why not? How much free storage do you get with google photos?
How do you use apple for music? Do you mean streaming?
