Weegy: Flip the Optimus 4X HD over and you're greeted by a vast, white, textured and removable plastic back cover adorned with an 8-megapixel autofocus camera mounted in a flush, machined aluminum pod and flanked by a single LED flash (top left), [ another LG logo (embossed and centered below) and two horizontal slits covering the mono speaker (bottom left). Like with the earpiece on the front, the attention to detail and the fit and finish are impressive. The battery door's edges are beveled and contribute to about half of the handset's 8.9mm (0.35-inch) thickness, making the 4X HD extremely comfortable to hold despite its chiseled build.

Pop the back cover off and you'll find an NFC antenna embedded in the back of the door, with matching contacts on the phone next to the standard SIM holder and microSD card slot above the removable 2,150mAh Li-Ion battery. The battery door's edges are beveled and contribute to half of the handset's thickness. What's left of the sides of the Optimus 4X HD - the flat half that's not a part of the beveled back cover - is delimited by two chromed-plastic rims, one following the edge of the front glass, the other meeting the seam of the battery door. This white plastic area is host to various connectors and buttons: a standard 3.5mm headphone jack, secondary mic and power/lock key on top; a micro-USB / MHL port, primary mic at the bottom; a volume rocker on the left; and nothing on the right. Here again, LG shows impeccable craftsmanship, with a subtle, recessed, pyramid-like pattern adorning the white plastic left and right sides, and the volume rocker protruding just enough to be located by feel. Sadly, the Optimus 4X HD's "True HD IPS" capacitive touchscreen falls short of the One X's phenomenal Super LCD 2 and the Galaxy S III's brilliant ... (More)
