How big is too big for a smartphone? That's the question no one seems to know the answer to and some companies seem determined to answer. Sony is one of those companies, and the Xperia Z Ultra is one of its latest experiments. With its display measuring a staggering 6.4-inches, diagonally, it pushes the boundaries of what will fit in your pockets and hands.

Under the hood, however, Sony pulled no punches. It equips a Snapdragon 800 chipset, 2GB RAM, 16GB storage, a 3,050mAh battery, IP55 and IP58 dust proofing and water resistance, and a bevy of connectivity options.

As per usual, we subjected the Xperia Z Ultra to an unboxing before it goes deep into our labs, only to resurface for the full review and comparison videos over the next week. Until then, feast your eyes on the below video! less
