Nokia's surprisingly slim 6-inch Lumia 1520 (pictures)

Nokia's ClearBlack Display filter improves outdoor legibility. Its ultrasensitivity means you'll be able to operate the phone with a gloved hand or fingernail.

The 1520 features Windows Phone's new three-column UI.

Now when you press and hold the Back button (left), you'll be able to close apps from the multitasking menu.

This 20-megapixel camera keeps a remarkably low profile, barely sticking out from the phone's back panel. Nokia swapped out the Xenon flash for a dual LED.

The Lumia 1520 comes in black, red, white, and yellow. Red is the only shade with a glossy finish; the rest are matte.

Even though it sells for $200 on-contract with AT&T, off-contract, the 1520 is priced like other premium extra-large phones, $750.

You'll need this tiny tool to pop open both the nano-SIM card slot and the microSD card tray.

You can store up to 64GB of external storage in this compartment, which is flush with the phone's left spine.

A supersize smartphone, the 1520 has the potential to bust through smaller, tighter pockets.

However, it fit fine in my purse, and slips into plenty of looser slackers, blazers, and jackets.

One benefit of a larger screen is all the space you get to view photos, read articles, and watch videos.

Nokia's signature camera app uses sliders to adjust values for brightness, focus, and white balance.

It's impressive how little the camera module sticks out from the back panel.

The speaker grille on the back pumps out songs, videos, and game jingles with aplomb.

Nokia's 1520 and its midrange cousin, the Lumia 1320, are the first Windows phones to join the ranks of smartphone giants like the Samsung Galaxy Note 3 (left) and HTC One Max. Compare their specs here.
