Cam puts the Sony Xperia Z2 side-by-side with the newly announced Samsung Galaxy Note 4. It's hard to think of two more different flagships in the Android market: Sony's 5.2-inch 1080p display is dwarfed in size and pixel count by the Galaxy Note 4's QuadHD, 5.7-inch Super AMOLED screen. 

It's 20.7-megapixel vs. 16-megapixel in the camera specs battle, but it's the design and build of the phones that show the most interesting differences: Samsung went with a metal frame and shiny, chamfered edges around the ports. Sony's is all glass and metal and is much more square. The Xperia Z3's flat, glass back panel isn't the most pleasant in-hand, but the Note 4's soft-textured rear panel is fantastic to touch.

In all the processing and network specs, the Note 4 trumps the Z2. It has the 805 series Snapdragon (vs. 801), 2.7GHz quad-core vs. 2.3GHz, LTE Cat 6 vs. LTE Cat 4. Both do, however, come shipped with Wi-Fi 802.11ac. 

That said, the both perform well. This isn't a full dogfight by any means, just a quick, on-the-surface comparison.
