Omnia II sports a 3.7-inch WVGA AMOLED display. AMOLED is becoming the standard for Samsung's high-end smartphones and we were impressed by the quality on phones like the Samsung Moment and Behold II. One disadvantage is that there's no physical keyboard, however, so you'll have to rely on the virtual QWERTY keyboard with Swype technology. Swype lets you type faster and easier with one continuous finger or stylus motion across the screen keyboard.
