Background and Identification
The Samsung SGH-A237 is a "clam-shell" style cellphone released September of 2008 to be used with AT&T service plans. The hourglass design is distinguished by the display and camera lens on the outside shell. Once flipped open, the inside is characterized by the full color display, keypad (1-9, *, #), and navigation arrow pad. If unsure, the phone can be identified by removing the battery and checking the model number. This will be located on the white label with the round Samsung logo. It should read at the top "MODEL: SGH-A237."
