As the saying goes, “do not judge a book by its cover.” The Galaxy Grand is reported to have a 1.4GHz quad-core Exynos processor, Android 4.1.1 Jelly Bean, 2100 mAh battery, NFC, and supports Wi-Fi in all flavors, as well as LTE. That is not exactly a bottom-of-the-line list. The rest of the device has fairly close dimensions to the Galaxy S III. Given the larger display while remaining within 7 or 8 millimeters in overall chassis size, it would fit Samsung’s method to not let size get out of hand (though arguably not as effectively as with the Galaxy Note II) with a larger screen.
We may see this Galaxy Grand make its debut in the next week or two, and who knows, maybe it will show a design direction for the next flagship.
