The Samsung E250, the Samsung T539 Beat and the Samsung R220 are three older Samsung cellphones. Respectively, the phones have slider, flip and bar-type bodies.
Released in October 2006, the Samsung E250 features a phone book that can hold 1,000 entries, 10 megabytes of internal storage and a 2-inch TFT screen that can display 65,000 colors at a resolution of 128 by 160 pixels. The phone supports Bluetooth 2.0, FM radio and WAP 2.0 Web browsing. Users can reveal the keypad by sliding the lower half of the phone downward.
Samsung released the flip-type T539 Beat in October 2007. The phone features two parts, a screen and a keypad, that are connected through a hinge in the middle. The T539 features 30 megabytes of storage, a 2-inch screen with a resolution of 120 by 160 pixels, and a 1.3-megapixel camera. The phone detects when the user closes the hinge and turns off the screen to preserve the battery.
Released in 2001, the bar-type R220 features the screen and the keypad on the front and features no moving parts. The phone has an antenna on the top right. It has a phonebook that can hold 100 entries and a call memory that can remember 10 dialed, 10 received and 10 missed calls. It features a monochrome screen with a resolution of 128 by 64 pixels and blue back-lighting.
