LG V50 on Corvus OS. Unfortunately nobody is developing for the phone so I guess this is where I stay for a while. A phone that is waterproof, has a headphone jack (Quad DAC) and MicroSD card, and isn't a Sony just doesn't exist nowadays :/
LG V60 here... My next phone will definitely be the Xperia 1V for that exact reason. Cameras are good enough (and gcam exists) on all flagships now for that to be a non-factor for me. Don't get me wrong, I do want good cameras, but I also want my mSD card, headphone jack, IP rating, wireless charging, and large battery. Name another (new) phone that ticks all those boxes.
I just can't stomach the price. I paid $500 to furnish my sister in law, father, brother in law, and my wife with the V50. They are insane value right now.
