Similar to other slider phones, the SGH-P777 is fun and easy to use. You can make calls with the slider open or closed, or you can set the handset to automatically pick up when it's opened. Be advised, however, that when the handset is closed and the backlighting is off, you must open the phone in order to do anything. Extending the slider exposes the backlit keypad, but otherwise, it's hidden away to avoid misdials. One issue that we've experienced with slider phones is that the keys are flush with the surface of the phone, so dialing by feel can be difficult; the SGH-P777 is no exception. Additionally, the keys seem small and are somewhat cramped. Also, since the phone has so many messaging options, you'll find yourself thumb-tapping messages on it, though this layout isn't terribly good for that.
Just beneath the screen, the SGH-P777 sports a five-way toggle that can be used as a shortcut to four user-defined functions; the OK button also acts as a shortcut to the Web browser. A thin LED light surrounds the toggle, and you can select from seven color options. To the left and right of the toggle are soft keys, while the Talk and End keys sit right below them. Under the toggle, you'll find a Clear key that backs you out of menus and deletes text that has been typed.
On the left spine are the volume rocker and the proprietary headphone jack. On the right side are the IR port, a button for activating the MP3 player, and a dedicated camera key. On the back is the 1.3-megapixel camera lens and flash; when the slider is open, you're greeted with a small mirror that resides above the lens and flash. The SGH-P777 also ships with a USB cable for connecting the port at the bottom of the phone to your PC.The Samsung SGH-P777's phone book stores a whopping 1,000 entries with room in each for three numbers and an e-mail address (the SIM card holds an additional 250 contacts). You can assign a picture and any of the phone's 12 polyphonic ring tones to a contact. In addition, the handset boasts a vibrating alert, an alarm clock, a calendar, a to-do list, a calculator, text and multimedia messaging, voice memos, and a currency exchanger. The P777 also supports three-way calling and auto-answer, as well as speed- and voice-dialing features. When it comes to data, the handset supports EDGE high-speed transmission; supports POP3, SMTP, and IMAP4 e-mail; and ships with mobile versions of AOL Instant Messenger and ICQ. You also get an infrared port and the ability to sync the address book, the calendar, and the to-do list with a PC. Since the SGH-P777 is such a high-end, feature-packed phone, we really would have liked Bluetooth and a speakerphone. Their absence baffles us.
