The Samsung S5230 bar phone is a bit smaller than S5600 and has a larger 3-inch LCD display. This model also has the TouchWiz user interface, Gesture Lock, and a 3-megapixel camera but no 3G support if compared to S5600. The Gesture Lock function allows unlocking the phone and going to menus by drawing an English letter on the display with your finger. The menu-letter link is user-defined. The phone supports microSD memory cards up to 8 GB and has 50 MB of the onboard memory.
