Basic Features
Released for Cingular Wireless, the Sansung D807 features GSM quad-band
(850 / 900 / 1800 / 1900 MHz) technology, permitting use of the handset
on compatible GSM networks in North America, Europe, and Asia, provided
it has been unlocked.
Locking phones is a common carrier practice to keep customers from purchasing
phones at a discounted rate with a service plan and bringing them to other
carriers. Since the D807 is a Cingular exclusive, it's locked by default.
But good-standing customers can usually request the unlock code after 90
days of service. Only after the handset has been unlocked can users take
it to other networks.
Samsung offers a straightforward 3 x 3 menu that can be easily navigated
with the four-way directional button or by entering the 1-9 keys that correspond
to each item. To get a custom look, the D807 gives the user the option of
changing wallpapers, ringtones, and skins but the menu can not be altered.
Essential for the business user, the phone features a clear and easy
to use speaker phone. To enable the speakerphone, users simply press the
middle select button in the center of the directional button when answering
or during a call. The sound on both the speakerphone and the earpiece is
low. Loud environments can be troublesome for D807 users, who may struggle
to hear the other party they are speaking with whether they are holding
it up to their ear or have it on speakerphone.
 Samsung
rated the D807's 880 mAh Li-Ion battery at 5.0 and 250 hours (10.4 days)
of talk and standby times respectively. However, these times are under optimal
conditions and testing suggested it may yield a lower performance. Moderate
to high users may find it necessary to charge the phone nightly to avoid
battery troubles. While charging, the LCD remains lit so users who are not
interested in having a night light will need to lay the phone on its face.
Screen
The centerpiece of the D807's sleek design is the vibrant 262K-color
LCD screen that offers 176 x 220 px resolution. Built from TFT (Thin Film
Transistor) technology, the D807's high resolution LCD offers bright and
vivid colors that allow the screen to remain visible even in direct sunlight.
With TFT technology, circuit transistors placed directly on the glass
provide fast refresh rates because each pixel location does not have to
be scanned. This allows for noticeably faster response times for games or
for use as a viewfinder and brighter, more distinct colors. The drawback
with TFT is its significant power consumption and the resulting reduced
battery life.
To conserve battery life, the D807's screen can be set for different
intervals to fade out and turn off (15 sec, 30 sec, 1 min, and 3 min). To
see the time or check the phone's static information, the user must slide
the phone up or press the left softkey. With Samsung's knowledge and expertise
in flat panel displays, the D807's 262K-color screen offers an optimal balance
of performance and battery life economy.
