It was less than a year ago that HTC revamped its smartphone line with the handsome and well-performing One series, but now that the holidays are coming the manufacturer has seen fit to update a couple of its models in the form of the mid-range One VX and the top-end One X+. Both HTC and AT&T have already revealed the two devices — and we have spent a bit of time with the international variant of the One X+ — but now we're getting a closer look at both of these smartphones.

The One VX is the more interesting of the two phones as it features an updated design over the One V that it replaces. Its tapered and curved edges, as well as its inlaid black face fails to make the phone truly stand out, but it does remind us a little bit of the Nexus One, and even more of the One V. The phone feels very plasticy — don't be fooled by that gray bezel. The back plate is removable on this model, however, unlike the One V. When it comes to specs the device's 4.5-inch, qHD display does disappoint a bit, but it is a good sight better than the 3.7-inch, 800 x 400 display on the One V, and it's thankfully not PenTile. It's powered by a dual-core 1.2GHz Qualcomm Snapdragon S4 processor, has 8GB of storage, a 5-megapixel camera, and it's relegated to Android 4.0 for the time being. Performance didn't disappoint.

The One X+, meanwhile, looks nearly identical to the One X before it, except it only comes in matte black with an excellent-feeling soft-touch finish. While the international version features angry red highlights to tip off its upgraded internals, AT&T's variant gets a globe logo front and center instead. You can see a full hands-on of the device here, but be sure to check below for some more photos of the AT&T variant of the phone, which is the same save for its LTE connectivity and carrier logo. The One X+ is thankfully running Android 4.1 Jelly Bean, and it's skinned with what's now called Sense 4+. The skin slightly modifies camera and gallery controls, and Google Now is present.

Niether HTC nor AT&T will give us pricing or availability for the two phones, but the last we heard was that they'll be on shelves "in the coming months."
