The Nokia 6100 is a popular mid-range Nokia mobile phone that was available from 2002 to 2005. It has since been discontinued in favour of more advanced models.
The Nokia 6100 is Nokia's lightest phone ever with a full 12-key keypad. Combined with its battery, it weighs only 76 grams (2.68 ounces) and measures 102 x 44 x 13.5 mm. Its smaller size compared to other contemporary phones might make it difficult for the elderly, or people with large fingers, to use its keypad. The phone does support X-Press On covers, and is packaged along with any of 4 colours. The Nokia 6100 has a 128 x 128 12-bit (4096 colors) display. Its features include Internet connectivity via GPRS, an infrared port, inbuilt calendar and polyphonic ring tones. It does not have a camera. It could be considered the true successor of the Nokia 8210 in terms of design functionality and its small flat size.
There have been issues with loss of sound or distorted sound from the earpiece, while sound from the speakerphone function is fine. This is caused by a defective speaker which is relatively easy to replace.
The LCD screen comes in two main versions which are very similar. One version of the LCD is controlled by an EPSON S1D15G00 driver chip, whilst the other version uses a Philips PCF8833 instead. There are also clones of these drivers.
Both driver chips allow the display to be used with 8-bit (256 colors) or 12-bit (4096 colors) RGB. Only the Philips version provides, on a low-level, the ability to use 16-bit RGB. This is achieved through dithering. 16-bit RGB gives 65536 different colors, sixteen times that available in the Nokia 12-bit RGB colour mode.
