The HTC One's successor, "The All New One" will come with a dual camera module for 3D-capture and refocusing.

HTC was expected to launch its new flagship smartphone, the successor to last year's HTC One, at the Mobile World Congress in Barcelona but we waited in vain. All we got from the Taiwanese manufacturer at the show was the Desire 816 mid-range device.

By now it seems the new model will finally see the light of day at an event on March 25. Today some of the rumors that have been floating around the web for a while have been pretty much confirmed by a leaked snapshot of a print brochure from Australian carrier Telstra.

At DPReview Connect we are of course most interested in the device's "Duo Camera," about which the promotional leaflet says the following:

Create vivid images even in low light and professionally edit memories after you've taken the shot. Choose where to focus, highlight what you love, soften backgrounds and add 3D effects.

Unfortunately there is no information about pixel count, sensor size, aperture or optical image stabilization, but the leaked information seems to indicate the new model will come with two cameras to facilitate 3D-capture, as well as refocusing of images, with results similar to what one might get from a Lytro light field camera.

This seems like a gamble on HTC's part. Previous attempts at dual-lens 3D-cameras, such as Fujifilm's FinePix Real 3D W3, were commercial failures; and recent smartphone models from the competition, for example Sony's Xperia X2, Samsung's Galaxy S5 or the Nokia Lumia 1520, all offer a software-based version of the refocusing feature that quickly adjusts the focus while capturing a burst of images, and mimics 'refocusing' by letting you choose the image you like best.

Compared to a dual-lens solution, this method has the disadvantage that subject movement can be noticeable in the final result. However, given the fairly gimmicky nature of the function in the first place, this arguably isn't a deal-breaker for most users. 

Apart from the Duo Camera, the leaked leaflet provides the name of the new device. In an almost Apple-esque move it will be called "The All New One". It'll also have a 5-inch display and run an updated version of HTC's user interface, Sense 6.0. You will also be able to double-tap the screen to wake up the phone from sleep mode, just like the LG G2's Knock-On feature. In our review we really liked the sound quality of the HTC One, and it appears its successor will again come with front-facing speakers and HTC's Boom Sound system.

Of course it's possible that HTC will use the dual-camera setup for features and functions that we can't even think of right now. We are curious to find out and learn about the device's complete specification when it's officially launched in a couple of weeks time.
