Following on from the Optimus G and Optimus G Pro, the G2 takes its place at the top of LG's mobile lineup and it's hoped it will get a bigger global rollout than its rather Asia-orientated predecessors.
Here are the first impressions of the device from the TechRadar team.
LG says the G2 "shifts the paradigm in smartphone design". While we're not so sure about that, it has put the volume buttons on the rear of the device underneath the camera lens, making this the first smartphone to be completely devoid of side controls. Interesting.
This is all part of LG's design "for one-handed operation", something that also comes through on the software side, with features such as Answer Me, which lets you answer the call by pushing the down volume button when the phone is raised to your ear.
The handset houses a powerful 2.26GHz Qualcomm Snapdragon 800 processor with the predictable choice of either 16GB or 32GB of internal storage.
There's 2GB of RAM on board, so it's not short of the ability to multitask. The bad news is that the G2 is running Android 4.2.2 rather than Jelly Bean 4.3. Disappointing.
There's a full HD 5.2-inch display, which should is larger than the Samsung Galaxy S4's and should be rather great to show off the pictures you take with the rear 13 MP camera.
LG G2 release date and networks/carriersLG says the phone will come to over 130 carriers around the world, and we'll let you know as soon as we hear more about any of these as well as the LG G2 release date.
Before we forget how accurate they were, here are the earlier pre-launch rumours surrounding the LG G2.
All our earlier LG G2 rumoursJust hours before the event, notorious Twitter tipster @evleaks tweeted a picture of what appeared to be a press image of the G2.
Having spelled out the name of the handset and the launch date, we're still a little unclear on the LG G2 release date, although rumours until now have pointed towards a late August/early September launch.
The CFO accidentally gave the game away by stating the G2 will launch next month in Korea, September in North America and Europe, and October in other regions, with Verizon as an official carrier partner in the US, but this has since been refuted by the South Korean brand.
However, we're now hearing that the handset could go on sale on the day of its august 7 launch, at least in the US. But as LG's home is Korea,
Pricing is equally as elusive at the moment, but taking a look a the specs below the G2 will probably be going head to head with the HTC One, Samsung Galaxy S4, Nokia Lumia 1020 and iPhone 5 - so expect to be shelling out a lot.
LG G2 displayThe LG G2 is a flagship device which means it's going to be sporting a pretty big display with a juicy resolution to really show off.
Various leaks have pointed towards a 5-inch, full HD screen and apparently it's cued up to sport a super thin bezel, which should keep the dimensions somewhat under control.
However more recent reports have suggested that the screen may actually be slightly larger, with a couple of leaks pitching 5.2 inches as the display size.
Resolution is thought to be a pin-sharp 1920 x 1080, putting the G2 in line with other full HD handsets such as the Sony Xperia Z and Galaxy S4.
LG G2 processorYou can expect to find a pretty meaty processor packed inside the LG G2, with a 1.7GHz quad-core chip appearing as an early leader in the leaks.
A benchmark test claiming to be for the LG G2 shows that the handset could have a Snapdragon 800 processor - which was later confirmed by Qualcomm and LG as the chip of choice for the next generation G-series mobile.
Another report claims there will be a number of variants of the G2, with some packing 2GHz chips and others a more tame 1.5GHz option.
There's also been the suggestion that the G2 could even pack a punchy 2.3GHz quad-core processor, which would deliver some serious power - so in short the speed is still up in the air.
What seems to be staying consistent throughout all the chatter however is the RAM, which has been listed as 2GB pretty much everywhere.
LG G2 operating systemWith Android 4.3 all but confirmed and featuring on the new Nexus 7 2 tablet, the LG G2 is really set up to roll off the production line with the latest version of Google's operating system, or so you may think.
Some reports have said that the G2 will launch with Android 4.2 Jelly Bean, which is certainly not out of the question as manufacturers tend to be a bit behind Google and its software rollout cycle.
It's also been suggested than the G2 could launch with an even older version of the OS, Android 4.1.2, but this seems pretty unlikely.

LG G2 accessoriesDue to an impending leak, the LG G2 official cases have been shown off to the world, with a variety of colours accompanying the little window mode.
This will allow you to control the music, answer the phone, see the time and more without opening the front cover. It's a lot like Samsung's Galaxy S4 S View cover - but it's by LG, and that's a brand that would NEVER copy its South Korean rival... right?
Other specsStorage is another important aspect on today's smartphones and the LG G2 should sport a respectable 32GB of internal space - although some of that will be taken up by the Android OS.
And if a leaked manual is to be believed, phone will use next-gen nano-SIM technology found in the iPhone 5. The same document also reveals that the phone will have a microSD slot, which will be music to a lot of people's ears.
Battery life is always a concern with the highly powered, large screened, full HD handsets and early reports pointing towards a 3000mAh power pack look to be a little optimistic. In fact, if that leaked manual is to be believed, we now believe that the phone will sport a 2610mAh battery.
Conflicting images have popped up apparently confirming a 2540mAh battery for the G2, which is a touch smaller than the Galaxy S4 but bigger than the HTC One - with the added bonus of also being removable.
If the G2 is to go head to head with the Galaxy S4, Xperia Z and Lumia 1020 it will need to have a half decent camera, and a 13MP snapper should fit the bill.
A little design quirk which looks almost certain to be on the LG G2 are a couple of buttons on the rear of the device, just below the camera lens.
From various photo leaks these keys appear to be replacing the traditional volume rocker switch usually found on the side of smartphones.
There's even a video online claiming to show the LG G2 in all its glory - back buttons and all.
Update: If you fancy a bit of colour in your life than you may be in luck, as according to new images which have appeared on Twitter the G2 will be available in a number of hues - although we're less than convinced about the legitimacy of this.
