HTC began a “teaser” campaign promising “big things ahead”, which was seen as a reference to the recovering Taiwanese vendor’s previously mooted One Max phablet.

This came shortly after further reports of the specifications of the device, which suggest it will have a 5.9-inch full HD (1080p) display. Another possibility is that it will include a stylus, similar to Samsung’s market-leading Note line.

Other mooted specifications include a quadcore Qualcomm Snapdragon 800 processor – similar to that used in Sony Mobile’s Xperia Z Ultra phablet – and support for Android 4.3. The device would also include an “ultrapixel” camera similar to that used in HTC’s One, and have a similar dual speaker format.

The device would join the existing One and One mini to give the vendor three devices in its flagship portfolio – a similar approach to that taken by Samsung with its Galaxy S4 range.
