The Samsung Galaxy S3 and the HTC One X are the indisputable stars of the Android smartphone market these days. Neither one has enjoyed a proper US release, but pretty much everyone agrees that the two are the best Android has to offer right now.

However, things change so rapidly in today’s technology world that nobody would be surprised if someone came out with a better  Android smartphone by the end of the year. Well, that possibility is now a probability: a so-called LG LS970 Eclipse has just been leaked with some out of this world specs.

The device, while far from being official, is said to be powered by a quad-core 1.5 GHz Qualcomm Snapdragon S4 processor (codenamed Krait) and to feature an Adreno 320 GPU, as well as 2 GB of RAM. That’s right, this might be the second ever phone to come with 2 GB of RAM (after the recently unveiled LG Optimus LTE2) and it could also feature a faster chipset than anything we’ve seen before.

You might remember some benchmarks from a while ago that showed the dual-core S4 processor performing faster than Nvidia’s Tegra 3 platform. Well, that was only dual-core and was doubled by an Adreno 225 GPU. So, can you imagine how a quad-core S4 chipset could perform, helped by an Adreno 320 graphics processing unit?

The rest of the Eclipse’s leaked specs include an impressive 13-megapixel rear-facing camera, a 1.3 MP front-facing webcam, 16 GB of internal storage, a 2100 mAh battery, and a 4.67-inch WXGA LCD TFT display with a 1280 x 768 pixels resolution.

The Eclipse might be sold by Sprint and run on its budding 4G LTE network. In spite of the amazing specs inside, the device is set to measure a mere 8.6 mm (0.33 inches) in thickness. We are unsure if BriefMobile’s unnamed source is trustworthy, but it has seemingly managed to get hold of a photo, in addition to the phone’s spec sheet.

There’s not much we can say about the Eclipse’s design from looking at the pic (it is from the back and not very bright), but it seems to look a bit similar to the Motorola RAZR. You will also probably notice a strange hole in the phone’s body, but we’re positive that’s the result of the testing process.

As far as availability and pricing goes, the source failed to offer any specifics, but said that the phone is expected to ship somewhere in the fourth quarter. That could be five months to seven months away, but I feel that this device, if it proves to be real, is definitely worth waiting for. How about you? Do you think that LG has what it takes to challenge Samsung and HTC for the Android smartphone “throne”?
