LG Quantum Review

Introduction and Design

The launch of Windows Phone 7 has been greeted with open arms and adulation by consumers all around due to its fresh new looks, responsiveness, and the complete reinvention of a Windows OS on a mobile scale. But compared to the majority of the existing pack of Windows Phone 7 smartphones, the LG Quantum C900 separates itself ever so slightly by being the sole one to sport a landscape style QWERTY keyboard. Since it's priced evenly with the existing crop at $199.99 with a contract, will its keyboard become the driving force to persuade customers to choose it over other offerings?

The package contains:

  • LG Quantum
  • microUSB Cable
  • Wall Charger
  • Quick Start Guide
  • 3.5mm Stereo Headset


Even after glancing over the LG Quantum a couple of times, it's quite telling that its design doesn't necessarily take precedence over the alluring look of its brand spanking new mobile platform. Instead, its approach is much too ordinary as it borrows styles featured on previous handsets with its predominantly soft touch coating exterior and accenting metallic rear cover. Upon holding it, there is no hiding the kind of weight (6.21 oz) it's packing as it also looks a bit more bulky (0.60” thick) compared to the streamlined nature of something like the Motorola DROID 2. However, its solid construction provides a sense of durability in fending off the adverse affects of normal wear and tear.

You can compare the LG Quantum with many other phones using our Size Visualization Tool.

The LG Quantum employs a brilliant looking 3.5” TFT display thanks partly to is WVGA (480 x 800) resolution. Essentially, it's able to provide ample visibility with even the tiniest of text, and colors that retain their natural tones in just about every angle.  Moreover, the level of responsiveness is accurate enough in registering subtle touches and complex gestures. Though, we're not particularly too content with its brightness output as it still requires being shielded in direct sunlight.

It's near impossible to accidentally press either of the capacitive buttons, the back and search keys, because they're spaced so far apart from one another. As for the home button, which is an actual physical one, its placement squarely in the center-bottom is fitting – but it's rather difficult to feel out seeing that it's almost flush to the surface.

We're fairly content with the snappy opening and closing mechanism of the handset as it locks firmly into place to expose its 4-row keyboard. Despite being somewhat flush to the surface, buttons are large enough to make them distinguishable by any finger size. Moreover, the decent tactile response it exhibits manages to enable speed typing without much pause or fault. However, we find it strange that the shift and function buttons, which are recessed and difficult to press, are separated from the rest of the keyboard on the left side.

The microUSB port is hidden behind a plastic flap on the left side of the phone, while the thin looking volume rocker and two-level shutter key are placed on the right side. Unfortunately, there is some difficulty in distinguishing them and they offer a lacking response when pressed. On the top edge, we're greeted to the appropriately placed 3.5mm headset jack and dedicated power button – the latter of which shares the same indistinguishable feel of the other buttons.

Turning over to its rear, we find the 5-megapixel auto-focus camera with LED flash in its usual spot, while the speakerphone grill hugs close to the bottom edge. Removing the back cover is accomplished with an effortless yank which will then provide access to the 1,500 mAh battery and SIM card slot.
