I wouldn't say it's a step down from either. They look equal to me. The V30 definitely has more options.
I disagree man. Maybe I have a defective device but of all the phones in our house, iPhone 7 plus, Galaxy S6 edge, Galaxy S4, and LG v30, iPhone is very easily the best camera picture quality on auto-mode, and the v30 easily the worst in auto-mode imo of those 4 phones.
Having said that I'd never want to have an iPhone as my daily phone, other than for the crisp detailed stunning photos it takes.
The Samsungs are nice but are absolute junk for battery life. For me owning Galaxy phones meant either always bring a wall charger to work or your phone will die before you get home.
The v30 with a nearly useless camera but incredible battery life, and it's wonderful DAC has changed my priorities for now in selecting a smartphone. I'd hate to go back to baby sitting the battery and also tethering headphone amps with rubber bands to my phone. The v30 is too good for me to go back to other phones.
