lg_g3_conceptLG have been sending out invitations to a special launch of a brand new product on the 27th May. The main event will be held in London with spin-off events also being held in Seoul, San Francisco New York, Istanbul and Singapore. It's fairly safe to say that LG will be unveiling their much anticipated new flagship smartphone, the LG G3. So what can we expect?

Let's start with the design. There are rumours that the LG G3 will feature a polycarbonate frame with a brushed metallic finish. It's thought to be around the same size as the Galaxy S5 but it will come with a bigger screen, possibly as large as 5.5-inches. We could see a super impressive screen on the G3 with claims that LG have used a 1440 x 2560 Quad HD display which would mean a super-sharp resolution of around 534 pixels per inch. There's speculation that the LG G3 will be powered by an octa-core processor possibly a 2.3GHz version and it will come with 3GB of RAM. The G3 could also boast a long-lasting 3000mAh battery.

The LG G3 will run on Android KitKat 4.4 and is expected to include 32GB of onboard storage which can be expanded with a microSD card. It's thought that the G3 will feature LG's Optimus User Interface which is rumoured to have been upgraded especially for the G3. There are reports that the UI has a flatter design and it will customise itself according to the how the handset is most commonly used.

The speculation is that the G3 will come with a 13-megapixel rear camera complete with optical image stabilisation plus, along the same lines as the LG G Pro 2. The rear mounted camera is expected to come with a dual LED flash and the front-facing camera is likely to be 2-megapixels. Like its predecessor the G2, the G3 will also sport volume controls on the back of the handset. The speculation is that the G3 will be available in 3 colours which are said to be White, Black and Gold. It may also include some element of water and dust proofing.
