I bought this phone sometime last year on eBay and it was still available on some other online stores, it got stolen a few months later. I want to buy another now but it seems to be sold out from every corner of the internet now.
It was a limited release so that might explain the scarcity but I still expected at least one shop to have it in stock.
I would not be surprised if you can't buy one since the LG V Series of phones change very rapidly:
The V35 looks like a V30 with a faster CPU. The V40 has the same CPU as the V35, but a newer camera setup. The V50 close to the V40, but with a newer CPU and 5G support.
My guess is that once LG starts making a new V series they stop making the previous one and that would explain the limited release.
