Although on the surface the phone looks very similar to previous ones, every aspect of the handset has been improved. Firstly, the camera has been upgraded to a 1 megapixel unit with a flash, the internal screen is now a 176x220 pixel TFT display in 262,000 colours. An obvious addition is three keys on the outside of the case to control MP3 playback E720 has 90Mb of internal memory. And, unlike almost every other Samsung before it, the E720 now includes Bluetooth.
