This post seems trollish... Or... From a very young person...
Who knows.. But it does seem a bit premature. First. There is not a huge gain from 6 to 8 in ram. I doubt you would see much if any performance gain, especially once Pie is released.
The notch is here to stay. It can already be hidden in settings.
As for comments on the phone itself has LG ever gotten good reviews from all the Apple and Samsung fan boys? You can find some great positive reviews if you ignore certain people or groups that slam the V40. Plus I here V40 sales were great over the holidays. They ran a lot if sales and I am kicking myself for being impatient and ordering day one again. I could have saved $200 or more.
I also doubt you will see a huge battery upgrade as I get the same battery life with this as I did with my V30 and they claim it will improve with Pie as well.
What downgrades has lg done? I suppose that's subjective. Some lined the V20 second screen (I never used it). I did like the swappable battery but it took two batteries to get the life I get with my 40 and previously V30. Battery life was horrendous on the V20.
Prices are not going to drop for Flagship phones. The best bet, as I complained about above, is to wait for sales. Do not buy day one.
