Just days before Mobile World Congress (MWC) 2013 HTC unveils its Android smartphone flagship-- the HTC One, a 4.7-inch successor for the One X mobile family.

Unibody construction is in aluminium with an optically bonded 4.7-inch LCD display featuring 1920 x 1080 resolution and 468ppi pixel density. Inside are a 1.7Ghz quad-core Snapdragon 600 chip, 2GB RAm, 32 or 64GB of internal storage and a 2300mAh battery. Jelly Bean is the Android version of choice, as reskinned with the latest version of HTC Sense UI.

Connectivity options include HSPA, LTE, NFC, Bluetooth 4.0, 802.11ac wifi and IR (allowing use as a TV remote control via HTC Sense TV app).

HTC claims the One offers "the best audio experience" through "BoomSound," the combination of x2 front-facing stereo speakers (apparently with the biggest sound chambers in a phone), integrated Beats Audio technology and a dual-microphone HDR recording option.

However the component HTC wishes to impress most with is the camera-- a 4MP number it calls Zoe. According to HTC the camera sensor uses "ultrapixels," larger (2.0 microns) pixels able to capture around 300% more light than the average 8MP mobile phone camera sensor.

The camera also has an f/2.0 aperture (the largest in current Android smartphones) with ISO settings ranging from 100 to 1600, allowing for performance levels reaching those of the much praised PureView technology inside the Nokia Lumia 920.

Further camera features include gyroscope-based optical image stablisation (OIS) on both front- and rear-facing cameras, HDR video recording and a Zoe option allowing one to record up to 3 seconds of full-resolution video and x20 still photos simultaneously.

The HTC One will hit most European markets from March 2013.
