LG KF750 ‘Secret’ review


The LG Secret (KF750) is the long awaited third offering from LG in their Black Label series. The secret with its carbon fibre back and tempered glass front teamed with a 5 megapixel camera, neon touch navigation and an accelerometer to boot it is no surprise it has been a huge success since the phone went on sale around the beginning of May, so can the Secret seriously compete with it’s competition?

The phone is sleek and rather bare button-wise however, this seems to work with the overall look and styling of the phone.











The Front Consists of a four way neon navigation in the centre of which is the main action button, then you have the standard call buttons and a cancel button. The front also houses an inner camera lens for video calls.












The phone just like the two black label series phones that came before it is a slider and when open you have the standard numeric keypad which consists of soft keys as appose to touch sensitive alternatives.

On the Back you’ll find a 5 megapixel camera with flash as well as the carbon fibre battery cover that adds to the phones toughness and overall styling.

The left side of the phone is home to a single proprietary input used for the headset, Charger and data cable.

The right however has slightly more to offer in the way of buttons from left to right you have a camera capture button, button to open multi tasking menu and an interesting Touch media button which if pressed allows you to use a number of applications that utilise the touch media functionality allowing you to use your finger on the LCD to play games view photos and access music and files, however this is not a feature available for all functions on the phone by any means, the volume controls are also located on this side of the phone they are used to control ring volume aswell as speaker volume and also used with the media features such as the MP3 player.

Highlights and Lowlights

+ Great Functionality

+ Slim Design

– Over sensitive neon touch

– Poor Battery Life




The LG secret comes full of promise and it delivers in so many ways, the phone is a great addition to the series and if a phone could be sold on looks I am sure this one would be right up there. However looks are not everything especially in the world of mobile technology. The “innovative” neon touch navigation is a great addition to the phone however due to it’s over-sensitivity can often feel clumsy and temperamental, The phone offers all the feature we have come to expect from an LG black label series phone and adds to them. The 5 megapixel camera is a welcome introduction and teamed with the fun editing function is perfect for those feeling creative however adding flowers and hearts to your city snaps is not going to be to everyone’s taste.

The phone is well laid out and despite the unpredictability of the neon navigation is easy to use and is well equipped for the average persons needs. The usual LG layout is present and offers no surprises in this regard.

Sliding the screen up reveals an attractive looking numeric phone pad consisting of 12 large and well spaced keys. The keys themselves have a nice positive action to them without requiring too much pressure. The only complaint here is that they are rather flat which makes using them without looking a little more tricky. The key illuminate nicely at night though.

The touch media function is an interesting one it allows the user to access music view photos and play games using the LCD as a touch screen however it seems like it would have made more sense to utilise the touch screen capabilities for all of the phones applications rather than a select few, that said this is still a solid feature and works well.

As a media player the Secret does a sterling job. Very impressed with the sound quality of the few sample MP3 files and easily out-performs a number of dedicated MP3 players that we’ve reviewed in the past. The secret has a MicroSD card slot situated under the battery cover but this only supports up to 4GB memory cards and not the MicroSDHC variety. Still, 4GB is good for hundreds of tracks and when you run our of pre-recorded content you can switch over to the FM radio. You can also change memory cards without removing the battery which is handy.

LG have included a pretty decent set of headphones with the Secret. These are the proper in-ear sound isolating kind and are probably the best headphones I’ve ever seen (of heard) included with a mobile phone. And if the headphones don’t suit you for any reason then that’s ok too as you can plug in any of your own that have a standard 3.5mm jack plug thanks to the in-line mic and volume control that’s part of the standard package. Why don’t all phone manufacturers do that?!

As mentioned earlier the phone houses an inward facing camera lens that is great for video calls. Another great feature of the Secret is the ability to use the multi tasking function that is accessed using the button on the right hand side of the phone, this allows for the minimising of files and applications while running several at once.

he web browser on the LG Secret is adequate and does a reasonable job of rendering standard web pages. You navigate the web pages using a virtual mouse pointer that jumps between links. However, just like the one on LG KF600, the mouse pointer moves rather illogically, which can become irritating on more complex pages.

As a final comment I feel I must say that for call quality and clarity the LG Secret is possibly one of the best phones that I have ever used. There’s plenty of volume through the earpiece and it seems to be large enough to produce a good range of sounds. Call quality from the other end is also good to LG must have included a decent MIC too!




Over the Secret is a great addition to the black label series and is certainly a future proof phone with great styling and functionality. The phone would be perfect for the studious university goer as the touch tempered glass front and carbon fibre battery cover means the phone would survive even the toughest nights out, however with hefty price tag the Secret carries it is sure to add to their student debt. Visit for debt consultant services. That said if you have the money to spare and are looking for a feature-rich, future-proof phone then you could do much worse than the LG Secret – it’s just a shame that I’ll have to give it back now!
