LG, like its Korean neighbour Samsung, has been an enthusiastic adopter of touchscreen technology for its phones. As well as producing touchscreen handsets based around its own operating system it has also snuggled up to Microsoft on quite a few occasions to kit its handsets out with Redmond’s Windows Mobile OS. It’s not much of a surprise then to find that the GM750 is among the first batch of devices to run Microsoft’s new Windows Phone offering.
The GM750 closely follows the design template that LG has used on previous handsets like the Arena KM900, Cookie KP500 and Renior KC910. At 13mm thick it’s slightly chubby, but not overly so and as it’s relatively narrow (by touchscreen standards) it actually feels quite comfortable to hold in the palm of your hand. And although the phone is mostly made from plastic it feels quite rigid and solid, while at the same time managing to tip the scales at a rather lightweight 119g.
As it’s a touchscreen phone, the GM750 is mostly controlled via onscreen menus, but LG has still kitted it out with a decent array of hardware controls. There’s an on/off button at the top that doubles as a lock switch, while the right-hand side is home to a volume rocker switch. On the left, you’ll find the dedicated camera button, plus a multitasking button to call up LG’s special multitasking menu. You’ll also find the microSD card slot here, while LG has positioned the micro-USB port on the top of the right-hand edge of the phone. Unfortunately this USB port also doubles as the headphone socket (we would have preferred a dedicated mini-jack socket for this), but at least the headset is a two-piece affair with a standard 3.5mm jack in the middle. This means you can swap the headphones for your own set of cans without losing the hands-free functionality.
The biggest change from the norm with the GM750’s physical design is the optical joystick that you’ll find nestled beneath the touchscreen. This works much like a traditional D-pad except that there are no moving parts. Instead, a sensor tracks the surface of the pad to work out in which direction you're swiping your finger so it can respond accordingly. It can be used for navigating around menus or for scrolling through long lists, like contacts in the address book, and works pretty well as it’s reasonably responsive.
