I love the Sony phones. If they sold the Xperia 5 V in my market (or even if the global version was compatible with my carrier's G5 bands . . . ) I would probably buy it in a second. They seem to be deliberately betting on only releasing the 1 V in some wealthier markets though (likely because the 5 V would undercut demand) -- but I refuse to spend 1 V prices with only a couple years of guaranteed updates.
Sony phones though are by far my favourite on the market these days, and it's a shame that they aren't more popular (or have enough developer interest to have LineageOS support).
