Editors' note: In light of the 2012 release of the LG Optimus M+, we have lowered the rating on this review.
LG broke new ground recently with its introduction of the Optimus line of Android handsets--affordable entry-level phones with surprisingly lust-worthy features. The company first made the Optimus T and Optimus S available on T-Mobile and Sprint, and Verizon had their own version made, dubbed the LG Vortex. Now LG has spread its Optimus wings to smaller carriers, such as MetroPCS, too. Appropriately named the LG Optimus M, the device also marks MetroPCS's first-ever Android smartphone. It has many of the goodies the other Optimus phones offer--Android 2.2, a 3.2-megapixel camera, Wi-Fi, and GPS--but it does lack certain features like tethering and hot-spot capabilities. The Optimus M is available from MetroPCS for $229, but bear in mind that's without a contract.
While the Optimus T, Optimus S, and Vortex look very similar to each other, the Optimus M is slightly different. At 4.57 inches long by 2.22 inches wide by 0.63 inch thick, the Optimus M doesn't quite have the curves and contours of its cousins, and it has a boxier silhouette. It's even slightly heavier at 5.39 ounces when compared to the Optimus S's 4.6 ounces. Despite its weight, the Optimus M feels a bit cheaper due to its hard plastic casing--the other phones have a soft touch surface for a slightly more luxurious feel.
On the front of the Optimus M is a nice 3.2-inch LCD with a 320x480-pixel resolution that looks similar to the other Optimus phones even though it only sports 65,000 colors. It's still sharp, colorful, and the smooth capacitive touch screen made it easy to tap and swipe around. You can adjust the brightness, the backlight timer, and the animations between window transitions. The screen also has multitouch, pinch-to-zoom, and a proximity sensor that shuts off the screen when you place the phone to your face during a call.
Like the interface on the LG Vortex, there are shortcuts to the phone dialer, the contacts list, the main menu, text messaging, and the browser along the bottom row of the home screen. The phone dialer app is pretty straightforward, as is the messaging interface. We're happy that the Optimus M comes with the Swype keyboard built-in, as an alternative to the standard Android touch keyboard.
Underneath the display are the usual Android hot keys in a row. The Menu key is on the far left, the Home and Back keys share a single panel with an indent in the middle, and the Search key is on the far right. At the bottom of the phone is the Micro-USB charging jack, while the 3.5mm headset jack and screen lock/power key are on top. The volume rocker and camera key are on the right spine. On the back of the phone is the camera lens. You have to remove the battery cover to access the microSD card slot.
Like the other Optimus phones, the Optimus M ships with Android 2.2. Even though it isn't the latest Gingerbread OS, LG has mentioned the phone is upgradeable to Android 2.3. However, Android 2.2 still has a number of notable features. They include voice dialing over Bluetooth, app storage on a memory card, a new camera viewfinder, app sharing, and Facebook integration in the contacts list.
