iPhone 4S Rival Alert : Samsung Galaxy S Advance Now Official

Samsung will get a few puzzled looks from journalists and observers after it announced the Galaxy S Advance, yet another addition to its popular Galaxy range of smartphones.

The phone, which is pitched as the successor to the Galaxy S (rather than a "lite" version of the S2), will be sold in Russia in February, before rolling out to the rest of the CIS, Europe, Africa, Middle East, Southeast and Southwest Asia, Latin America and China.

Samsung didn't say whether the U.S. would see the launch of the handset in 2012. Like the Samsung Galaxy S, it has a 4-inch, 800x480 pixel Super AMOLED screen with 768MB RAM, either 8GB or 16GB onboard storage, a microSD card slot, a 1500mAh battery, Wi-Fi, Bluetooth, GPS, a front-facing 1.3-megapixel camera and a rear five megapixel one and Android 2.3 Gingerbread.

The only real improvement is the addition of a 1GHz dual core processor (almost certainly the Nvidia Tegra 2 chipset) instead of the single core Samsung Hummingbird Cortex-A8 model.

At less than 10mm thick and 120g, the Galaxy S Advance is fairly light and pocketable. It's worth noting that Samsung already has a similar device in the UK, the Galaxy R which costs £300 and has a slightly bigger LCD screen.
