Is this blueprint showing us the HTC T6?
While the HTC One is 137.4mm high and 9.3mm thick, the device in the blueprint is measured at 140.4mm tall and 9.4mm thick. The Boom Sound front facing stereo speakers are on board. The rumored specs for the handset include a 5.9 inch screen with resolution of 1080 x 1920, a quad-core 2.3GHz Qualcomm Snapdragon 800 processor and an UltraPixel camera. A 3300mAh battery powers the model and it is believed that the HTC T6 will be powered by Android 5.0. or Key Lime Pie.
The second half of 2013 is going to bring a number of large-screened models. Besides the HTC T6, we will see the Samsung Galaxy Note III and the Sony Xperia ZU. The latter could end the year as the handset with the largest screen in the industry with its 6.44 inch Triluminous display exceeding the 6.3 inch glass on the Samsung Galaxy Mega 6.3.
