What if your Galaxy S4 had 3 GB of RAM, was powered by the scorching Snapdragon 800, instead of 600, had 32 GB of storage, and you could have it in "Coral Pink"? You don't need to dream anymore, as the Galaxy J just went official on DoCoMo in Japan with the upgraded specs above, borrowed directly from the Note 3.
The handset sports a 5" Super AMOLED Full HD display, and is slightly chubbier and heavier than the S4, with its 137mm x 70mm x 8.6mm dimensions and 146 grams of weight. That might be due to the eventual waterproofing that most Japanese flagships go through, though there are conflicting reports whether the handset is waterproof or not.
Still, we get Note 3 specs in a 5" casing that comes in attractive Coral Pink, Satin White, and Lapis Blue, and supports LTE-A download speeds of up to 150Mbps, so the Galaxy J is definitely droolworthy, and hopefully we will see it outside of Japan some day.
