I just got the Oreo update for my unlocked US996 earlier this month. I couldn't believe LG actually delivered on it. I wasn't happy to read LG was dropping support shortly thereafter. I am relieved they've walked that back. It would be nice to see the Pie update available for this great phone. Especially since their Oreo was finally available 2 years after Oreo was released and after Pie was released!
That said, my update was via LG and the update went smooth and flawless. Not huge changes, but they're nice and the phone runs better. Even added a live wallpaper which is fun. I really love this phone, the Quad-DAC sound and recording capability are just great, as is the call quality (it is a phone after all). AND I don't plan on changing to any smartphone that doesn't have a removable battery - smartphones cost way too much to treat as disposable for something like a battery change (I suppose it's ok if you get regular review models for free, but I don't). I really like the features LG builds into their phones (Quad-DAC being huge for me). Even detail things like (using LG's skin) being able to reverse-pinch the screen to reveal the wallpaper unobstructed, then pinch to bring back the icons, and being able to loop through the home screens without having to swipe all the way back to the first screen (hated that on the galaxy S5 I had before this) AND I find having the power button placed on the back far superior to the side (always kept turning the S5 on/off inadvertently pressing the darn thing). And they were first to put the fingerprint sensor there, below the camera which is also perfect.
It would be really nice to see LG start putting software updates as a priority along with well trained CS. Probably do wonders for their market share too. As far as I'm concerned their phones are hard to beat. Loved the G2 and really love this V20.
