LG KF510 Review

Introduction and Design

In the last years, many of the models LG has put on the market have an elegant vision, attracting the eyes of the crowd. LG KF510 is one of the fashion sliders of the company and it has been created as impressive as possible. LG is touting the model as the first one with gradient colors on the panel and a monolith look as if it didn’t open.

The first thing that came to our heads when we saw the LG KF510 was: „Oh, another elegant and beautiful model in the company’s product line”. And it really is, because at 0.4” (10.9 mm) it is quite slim and has pleasantly gradating colors. In our case, they go from black to grey, but the other version, which is red, is even a bigger attraction.

The weight of 3.9 oz (110 g) is justified by the materials (metal and scratchproof) used to make the phone. Unfortunately, the KF510 is a fingerprint magnet and in order to keep it clean and shiny, you’ll have to carry a handkerchief.

The entire front of the LG phone is encircled by a metal edge and is covered in scratchproof glass, which protects the 2.2” TFT, able to reproduce 262K colors. Indoors, the picture is beautiful, but once you try to use it in broad daylight, you get the annoying mirror-like effect, which makes the display almost unusable. Over it, we have its automatic light/brightness sensor and the speaker.

The navigation zone is separated from the upper part of the front with a slightly protruding chrome line, which helps to open the phone. Instead of buttons or a color display, like in KF600, here we see a touch sensitive area with LEDs, where we have the soft keys, the green receiver, and the “Clear” button. There are no arrows and you’ll have to either run a finger in or just touch the area, pointing at the direction desired in order to scroll. This system is actually pretty convenient, but as any innovation, it takes time to get used to it. However, you can only go vertical/horizontal. There’s also an option for a vibration feedback (three levels) or a sound, to confirm commands, in case you have difficulties understanding when it happens.

Opening the phone is easy and thanks to the monolith construction, it is more stable than most other sliders. Doing that, reveals the 12-button numeric keypad. Its design resembles a chessboard (like in Chocolate) and all buttons are in a similar square pattern, making them very pleasant to press. Their relief is slightly expressed and they are hard to distinguish, unless you are looking at them.

On the right side of the KF510, on the metal edge, are located the charger/handsfree connector, the camera/multimedia button and the closing one. Both have a well-expressed relief and are easy to find by touch. One untypical solution is that the red receiver is a sliding key. In order to reject a call, you have to slide and release it, which activates the touch pad so you can confirm. The first action can also be used to switch off the phone, so do not hold it for too long.

On the same side, the phone has a slot for a microSD card, but in order to see it, you’ll have to open the slider. It would have been better if there were indications in the front.

The top and bottom parts are free from any elements and on the left, we have the volume rocker and the strap hole.

On the back, is the back lid, covering the battery and a 3-megapixel camera with a small LED flash and a tiny mirror. Changing the SIM card is pretty hard since its house doesn’t come out completely and you’d have to push it in/out at an angle.
