That is a very fair statement. I have seen LG take a beating before and all manufacturers have flaws. I am certainly can not standing up for the G5, as I haven't seen it myself in person. I am interested in owning one and I can't say I don't have reservations because of the reviews.
What I do know is. Some people who have bought the phone have said they don't see the gaps. And they like the finish.Love the phone. The internet loves drama and about 75% of the hype around the quality usually can tossed right out the window. Lastly, I get irritated at the mob mentality. Meaning, some people like you post logical posts and concerns about the quality, where as many are just posting to beat down LG just for the fun it, so they can beat their chest about how great their Samsung phone is. They don't add anything to the discussion, nor have they ever considered buying an LG.
Those are the people my post was mostly directed towards. I also think people need to stand back a little and decide if the flaws are as bad as some would have you believe and this might actually be a very good phone. Much like the "bendgate" problem with 6s, which was a problem, but not a problem. That is the wait and see approach I will take.
