I've noticed in my country (UK) that I can pick up a Nokia 7.1 pre owned but in mint condition for around £170 which for the same condition Nokia 7 plus pre owned would be about £20/40 more but would it be worth going for the 7.1 or keep 7 plus? I know 7 plus sd660 us better than 7.1 sd636 but other than small things is it not worth getting 7.1. and why would u get 7.1 over 7 plus if yes
