Design concept offered by Samsung F400 can be called “attractive”. Construction adopted owned SGH-i450, “Dual slide“. When movable to the top of the range that appears keypad is flat surface with the meeting without separating the cavity between the keys. Meanwhile, when the movable down will raise funnel the audio loudspeaker.
The second of this sliding action, at the same time raise the menu of multimedia options. For example: FM radio, music player and movie player. Let’s select one, you can also enjoy the direct fury of the sound preparation from Bang & Olufsen ICEpower. Unfortunately, this performance loudspeaker can not rival the Walkman series of Sony Ericsson.
Back to the keypad and navigation key. The SGH-F400 presented two key fast with a new use. First, the “switch”, this button works as shortcut to choice menu favorite (Call, Message, Internet). Second, to directly display the video call mode, with a location in the top left.
On the front, we have the 2.2” TFT display with QVGA (240 x 320 pixels) resolution and 262k colors. The picture looks beautiful and bright but unfortunately in direct sunlight the glass covering the screen transforms into a mirror and nothing can be seen. Besides, it scratches easily which is very annoying. It “took us” about an hour of carrying it in a pocket with some keys to get some streaks.
From all navigational buttons, only the 5-way D-pad is not standard and is a rotating wheel. The same means of navigation are used in other models of the manufacturer like U700 and Juke. All buttons are easy to press and clearly felt.
The sliding mechanism of this dual slider is relatively shaky and doesn’t look very reliable. Pushing it down reveals the two stereo loudspeakers and at the same time, activates the music menu (more about it in Interface). Moving it in the opposite direction discovers the keyboard with purple backlight. All its keys are easily distinguished and pressed.
