To open the phone, push the surface of the phone upward. It feels most natural to do this with your thumb, but even then, we found it awkward as the front of the phone is slippery. A small plastic ledge underneath the display does make this a little easier. Yet as the navigation keypad is located underneath the ledge, we often accidentally pressed keys when we opened the phone. You can also adjust slider settings to answer calls when opened, for example, or hang up when closed.
The D900's display is absolutely stunning. At 2.2-inches on the diagonal, the 262,000-color screen displays rich and vibrant colors and easy-to-read text, even under bright daylight. As with other Samsung phones, the menu interface is colorful and animated, and we especially liked that you could view the submenu of each menu option when scrolling down the lists. You can adjust the screen's brightness, as well as its backlight timer. The dialing text can be configured with different backgrounds, font styles, font colors, and animation styles. Text messaging fonts can also be adjusted.
Even though slim is in, the real attraction of the D900 is its multimedia feature set. Yet the D900 is also chock-full of basic features, such as a 1,000-entry phone book that can hold five phone numbers, an e-mail address, and a note per entry. For caller ID, you can assign a group IP, one of 25 polyphonic ring tones, and a picture. The SGH-D900 supports MP3 ring tones as well, which you can download from your carrier or upload from an existing MP3 collection. Other basic features include: text and multimedia messaging; e-mail; a speakerphone; a vibrate mode; Bluetooth; voice recording; a wireless Web browser; an alarm clock; a calendar; a memo pad; a world clock; a calculator; a currency and unit converter; a timer; and a stopwatch. There's also a TV-out feature that lets you view the photos and videos on your phone on a television screen, as long as you have a connecting cable. The SGH-D900 is a quad-band world phone with EDGE support.
