Description

The Touch Dual is the slider-variant of the first Touch, very similar in design when closed. Opened, it reveals either standard numeric keyboard or (optional) 20-key QWERTY one with SureType-like design. The Touch Dual features 3G HSDPA 3.6mbps. As software, it is standard WM6 Professional smartphone but features the second generation TouchFlo interface which performs different actions based on they way a finger is scrolled over the display.

  • Technology:

    Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.
