Did you know that Samsung has a 5-inch smartphone of its own? The Samsung Galaxy Grand (GT-i9080) – as it’s called — isn’t garnering too many headlines probably because it’s just teased last month. Though you can’t find the phone in stores yet, the first firmware for the dual-SIM variant, which is known as the Galaxy Grand Duos, is already available to download.

You can get the Android 4.1.2 Jelly Bean firmware for the Samsung Galaxy Grand Duos (GT-i9082) on Sam Mobile’s website. From the description, it looks like the phone will be released in Russia and India first, possibly sometime in the first quarter of the year.

Despite the gigantic size, the Grand doesn’t sport a 1080p screen. Instead, you’ll find that it boasts a not so hot WVGA display (800 x 480 resolution). Other expected specs include a dual-core 1.2GHz processor, 1GB of RAM, 8MP main camera, and the aforementioned Android 4.1.2 Jelly Bean.

The Galaxy Grand and Galaxy Grand Duos will come in Chic White and Dark Blue. Those who are looking for some pricing information will have to wait until Samsung spills the beans some more.
