Just as Samsung unveiled the Galaxy S3 in front of a huge online and offline audience, LG made a similar announcement that for some reason, went unnoticed. LG wants some attention, folks.

The Optimus LTE2 is the most recent monster phone to come from one of Samsung’s longstanding competitors and, while some technical details about the device are still blurry, what we do know makes us think that this could actually be at least as powerful and cool as the Galaxy S3.

Set to hit Korea in just a matter of weeks, the Optimus LTE2 will be the world’s first ever smartphone to feature 2 GB of RAM. Samsung, Apple and HTC have all stuck with 1 GB of memory for quite some time and appeared hesitant to go to the next level in this area, so it’s sure nice to see someone not afraid to push the envelope.

Unfortunately, we don’t know what processor will the Optimus LTE2 pack under its hood, so we can’t say if this will actually be the world’s most powerful smartphone. Rumors point towards either a dual-core Qualcomm Snapdragon S4 chipset or a quad-core NVIDIA Tegra 3 proc, but we should wait and see.

Other known features include LG's own “True HD IPS” display (unknown size, though), as well as a 2,150 mAh battery with 40% longer life compared to the first-edition Optimus LTE. Other known details include Android 4.0 Ice Cream Sandwich, and support for wireless charging via a separate dock. Nice move, LG.

There are a few rumors going around about the phone’s screen size, with the most reliable pointing towards a 4.7-incher, but, once again, we should wait for official news and confirmation. What we do know, however, is that the display will use a full RGB matrix, which might make it brighter and crisper than the pentile screen sported by the Galaxy S3.

As for the phone’s design, this looks very similar to the first-edition Optimus LTE and this year’s L series smartphones. The case is rectangular and elegant, and might actually draw the attention of people who don’t dig the Galaxy S3’s “curves”.

The new Optimus LTE will hit Korea in mid-May (the exact date is still unknown), while other availability or pricing details are being kept under wraps. There’s no way to know, therefore, if the phone will ever see the light of day in the US or Europe, but, considering that it could be a real road-opener, it’s safe to assume that it will enjoy a worldwide release sometime soon.

What do you guys think? Could that extra 1 GB of RAM make the LG Optimus LTE2 rise to the top of your shopping lists? Could this become a more powerful and popular phone than the Galaxy S3? And finally, what’s your view on LG’s marketing abilities, considering the fact that this unveiling pretty much came out of the blue and was almost about to get completely ignored?
