Video-recording options consist of the same digital zoom, flash, brightness meter, geotagging, color effects, and white balances. In addition, there's audio muting and you can choose from six video sizes (ranging from 1080p to QCIF). There's also the silly faces mode, which will distort your face (for example, bulge out your eyes, squeeze your mouth inward) while the video records, and a background module, where you can change your background to outer space, a sunset, a disco, or your own custom image.
The front-facing camera offers the same brightness meter, white-balance options, color effects, timer, and geotagging feature, but there are only two scene modes (normal and night), no face tracking, and one image size (640x480 pixels). There's also a mirror image option that saves a vertically flipped version of your photo, a beauty shot meter that lets you adjust the brightness and blurriness of an image, and a voice command shutter function called Cheese Shot.
Video features for the front-facing camera are nearly identical to those of the rear camera, including the quirky effect modes, except there is no digital zoom or flash, and there are only three video sizes, ranging from QCIF to VGA.
Photo quality was decent and adequate for a camera in its class. In well-lit outdoor photos, colors were true to life and bright. While some objects outside the main focus area were blurry, the picture overall was clear and sharp. In dimmer and indoor lighting, dark hues were harder to distinguish, and there was a noticeable amount of digital noise and graininess. Colors also looked more washed out.
Video quality was impressive. When I shot in 1080p, objects (both stationary and moving) were in focus and crisp with well-defined edges. Recordings played back smoothly with a good frame rate, audio picked up well, and colors were accurate and true to life. There was little lag between my moving of the camera and what I saw on the viewfinder, and there were no rendering issues.
I tested the LG Mach in San Francisco. Call quality was mediocre. Although I could understand what my friends were saying, their voices sounded muffled and scratchy. During times of silence, I could hear a low but continual static noise in the background. Likewise, my friends said I sounded stuffy. As with past LG devices, speaker quality was poor. Voices, especially on max volume, sounded tinny and harsh. Audio from music and movies sounded similarly sharp as well.

The handset runs on Sprint's 4G LTE network, but I could only clock in 3G speeds in San Francisco. On average, the phone loaded CNET's mobile site in 15 seconds and our desktop site in 27 seconds. The New York Times mobile site took about 13 seconds, while its desktop version took 25. ESPN's mobile site took 33 seconds, and its full site loaded a minute and 14 seconds. Ookla's Speedtest app showed me an average of 0.12Mbps down and 0.02Mbps up. And, on average, it took 9 minutes and 45 seconds to download the 23.32MB game Temple Run.

The handset is powered by a 1.2GHz dual-core CPU. There was no hesitation with basic tasks like unlocking the screen, opening the camera app, and transitioning back to the five home screen pages. Switching between portrait and landscape mode (for instance, like when I opened up the keyboard) also showed little lag. Graphics-intensive games like Riptide GP performed well. Though I've seen smoother and higher frame rates on higher-end phones like the Nexus 4, images still rendered bright and crisp, and the app didn't stutter or freeze. On average, it took 37 seconds for the phone to reboot and 2.88 seconds for the camera to launch.
During our battery drain test for video performance, the phone lasted 7.15 hours. Anecdotally, it has decent battery life. Starting with a full charge, a 2-hour movie with brightness on maximum drained about 90 to 95 percent of its battery, and with heavy use throughout the day, a charge will be needed. According to FCC radiation standards, the device has a digital SAR rating of 0.49W/kg.
Looking at Sprint's current lineup of slider phones, I don't recommend the Mach over the . True, that handset is nearly twice the price of the Mach, but with that extra $100, you'll get an 8-megapixel camera, a beautiful 4.3-inch display, and a 1.5GHz dual-core Snapdragon S4 processor -- all in a stylish design.
