A Phone to Scratch for : LG U400 mobile phone


The latest LG phone has pretensions of being your personal DJ.

LG entered the UK mobile phone arena around three years ago. Since then the company has increased its mobile product portfolio to its current level of 35 models. One of these is the LG U400 unit which adds a 2.0 mega-pixel camera and DJ-style music...

LG - U400


Looking around at the current crop of mobile phones, you can't fail to notice how high music playback is on the agenda. Sound quality is getting really good, and with dedicated music buttons and plentiful storage ...

This is a neat little handset, visually appealing and suitable for small pockets. The scratching feature may not appeal to everyone, but a lot of attention has gone into the music playback features and generally this is a good little performer.

LG U400 3G Phone


After wooing us with the Chocolate fashion phone, LG is keeping up the pressure with the launch of its music phone, the U400. Can this funketeer have the same impact as its sweet stablemate?

Over-the-air downloads, 3.5mm headphones jack connection, expandable memory and A2DP compatibility - the U400 has the musical talent.

We're still not convinced about the jog-wheel to navigate and the location of the soft keys takes time to adjust. The camera lens is a letdown too.

It may lack the Chocolate phone's swoonsome body, but the U400 is a very capable music phone

LG U400


A mobile phone with an iPod like scroll wheel? No, it's not an Apple product, but rather LG's new 3G mobile handset. Exclusive to 3 Mobile, the U400 o...

Reasonable features list, Display, Music player, 3.5mm headphone jack adapter

Performance of scroll wheel, Battery life

The U400 offers a new control system but its performance isn't really up to scratch. The handset has a solid, if not outstanding list of features, but a poor battery life and chunky design don't do it any favours.

LG U400


For those who long for a music-focused phone with a slider form factor, the 3G U400 could be your device. Just be wary of the temperamental scroll wheel.

Sharp display looks great ; Many modes and options for video and photo capture ; Music playback sounds

Inconsistent scroll wheel ; No FM radio

The main problem with the U400 is the jog dial -- while it was apparently chosen to make navigating easier, the erratic onscreen responses to wheel movement made us long for a conventional button or joystick. We're all for keeping an open mind about...

Snapshot: LG U400


LG's recently launched U400 handset for 3 UK is a music lover's dream. It features a d-pad controller that serves double duty as a scroll wheel that can be used for navigation as well as for adding DJ-inspired scratch sound effects to music.
