Samsung has started to introduce a range of phones with colour screens so vivid and real they'll take your breath away. The technology is called AMOLED, which stands for Active Matrix organic light emitting diode. The great thing about AMOLED screens is that they are ideal for video because of their speed. Older OLED technologies had problems with ghosting when showing fast animations. One of the latest mobiles with an AMOLED screen is the Samsung GT-S8300 UltraTouch, also known as the Tocco Ultra edition, which makes the most of its enormous video capabilities and animation in its  classy and easy-to-use 3D Touchwiz interface. The UltraTouch is a quadband GSM and 3G mobile with HSDPA support. HSDPA stands for  High-Speed Downlink Packet Access, which provides download speeds similar to ADSL broadband. It has a slider keyboard.
