I’m stumped why LG has named its KF750 mobile the ‘Secret’. What's it supposed to hide, exactly? Not the fact that its touchscreen has some limitations, surely? But let me stop waffling and cut to the chase. And so, here's my take on LG’s stylish new handset.
Form Factor
This 12mm thick handset has a stylish carbon fiber body accentuated with leather. The chrome border only enhances its appeal. The KF750’s single button surrounded by a 6-key touch sensitive pad located just under its 2.4 inch 240 x 320 pixel display gives it a nice touch of sophistication and elegance. On the downside, the screen is a bit tricky to view in sunlight.
The slider is swift and extremely smooth going up, it’s on the way down that the Secret seems to have a problem. It could be that a locking mechanism prevents the upper portion from sliding down without a little effort. The keypad is well-designed and easy to use.
Just below the volume/zoom keys on the side of the handset is a shortcut key to access the Touch Media menu that activates the touchscreen features. Below that is the active applications key that shows you shortcuts to the desktop, main menu, and any active apps running in the background. A small symbol appears at the top to indicate any active apps. There's a dedicated camera key and the USB-cum-charging port-cum-(sigh)-handsfree slot on the other side.
A 5 MP camera with LED flash is located on the back and the hot-swap slot for microSD cards is under the rear panel. You won’t need to remove the battery to access the card, so no worries there.
Features and Performance
Interface, Interactivity
The KF750 has a certain Symbianesque feel. At least, the menus and navigation system look decidedly familiar, even without the colors and icons. On the whole the menu system of the KF750 is easy and clear enough to maneuver through.
