For just over a week, I’ve been using two phones interchangeably. The first is the Lava Xolo X900 with Medfield inside, the second is the flagship of HTC’s new One series, the HTC One X on AT&T. It’s a device with lofty goals, as it’s the flagship of HTC’s new branding and strategic positioning behind a single line of devices, industrial design, and focus. The strategy mirrors that of Samsung’s with their Galaxy series, and if successful will rekindle the excitement behind HTC’s brand.

The One X on AT&T is really a One XL (L for LTE), however in the USA the device carries full One X branding. We’ve got the International One X and One S variants which will be reviewed in short order, but for today we’re talking specifically about the One X on AT&T.

The One X is without doubt unlike any other HTC smartphone I’ve held to date. In fact, it’s a testament to how revised HTC’s industrial design is that I can even write that sentence. The phone is machined, not injection molded, from a single machined piece of polycarbonate plastic, and feels anything but cheap in the palm. If Nokia was really the first to demonstrate that you can have a polymer (read: plastic) device without making it feel second rate, HTC is the second OEM to do it properly. Probably the biggest part of that effort is giving the surface a proper texture. In this case the HTC One X backside is given a sand blasting for texture, while the sides remain slick with a piano finish gloss. It’s a great juxtaposition of textures that makes it easy to identify proper grip, and likewise break any homogenaity.

The buttons blend into the glossy sides of the One X, getting pretty close to the optimal combination of protrusion and clickiness. The power/standby button at top is no exception. Speaking of the top, there’s a secondary microphone for noise cancelation, headset jack, and finally the microSIM tray, which requires an ejector tool (provided in the box) like many other newer designs.

The case is again a single piece unibody construction. With exception of the microSIM tray, there are virtually no doors or covers, and the consequence is no flex, creaking, or chattering seams when the vibration motor is going. The speakerphone grille at the back and the earpiece at front are both arrays of pinholes no doubt cut with a laser through the polycarbonate. On the front, the notification LED (which shines green or amber) shines through one of the small holes. The only unfortunate part of this is that it’s hard to see the notification LED from extreme angles. At far right is the 1.3 MP front facing camera.

HTC has opted to place the microUSB port about one quarter of the way down on the left side of the phone. The result is that it’s possible to hold the device in portrait and type like normal without the cable poking into your hand. I also suspect that HTC has placed the majority of the PCB up top, and left the bottom three quarters of the device for the internal battery.

The rear of the device is again a softly textured finish. Our HTC One X is a dark, almost black color, but there’s also a white version as well. The white revision indubitably hides scuffing better than our black unit, though so far loss of texture at the contact points on the One X has been minimal. The surface roughness from HTC's bead/sand blasting is very high frequency, which is what makes it somewhat prone to appearing shiny after rubbing on planar surfaces. Interestingly enough I noticed that Nokia moved to a lower frequency surface texture on the Lumia 900 to combat this. I'm sure we'll eventually see HTC do something similar eventually. That said again the scuffing is minor.

There are five pogo pads at right for using a dock or accessory. I’m not sure whether the HTC Car Kit uses these pogo pins, but we’ve seen HTC and other OEMs use these for audio, power, and USB data signaling before. The camera module bulges out gently from the top center with a single LED flash at right.

The obvious mainstay of the One X is the 4.7" 720p infinity display which has a gentle curve at the left and right edges. The display isn’t curved, however the overall design makes it almost feel that way. Up top, HTC has done an excellent job hiding the ambient light and proximity sensor. I can spot the ambient light sensor, but it’s subtle, and I have no idea where the proximity sensor is, which is awesome. At bottom are the three capacitive buttons, which means the menu button becomes part of the UI for legacy applications that haven’t fully integrated it yet. I have no complaints with the capacitive buttons, this is something that has long since been completely settled and squared away. They’re backlit as well if the ambient brightness level is low enough. The result is even more vertical real estate than the Galaxy Nexus’ 720p display provides.

Overall I can’t understate how great the One X feels as a whole. It’s a new type of minimalism for the handset maker - mature, less chintzy and flashy like so many other Android devices. My only gripe is that the black color shows scuffs and loss of texture (from rubbing other solid surfaces at the contact points) more than I’d like - the white model probably makes more sense purely because I can’t imagine that showing.

What’s really interesting to me is just how many recent handsets from so many other OEMs have taken a similar design approach - microSIM, unibody polymer construction, no microSD card slot, and non removable battery. That combination of features seems necessary if you’re going to craft a device with competitive form factor this generation, and no doubt even more vendors will update with that profile. Polymer makes sense because it’s both a material transparent to RF, and easy to machine, and going with a microSIM makes sense since it’s all about minimizing area that isn’t dedicated to battery.

Next up is our specifications table. Again the chief differentiator between AT&T’s One XL turned One X is that the device has a Qualcomm Snapdragon S4 MSM8960 SoC, this is the first 28nm dual core Krait based part, and marks our first smartphone with it inside. The two krait cores are clocked at up to 1.5 GHz, and MSM8960 includes Adreno 225 graphics. The AT&T One X also includes 16 GB of onboard storage, and again there’s no microSD card expansion option.

To be totally honest, I always found the Sensation’s industrial design to be world class, it was a few other devices with carrier influence that showed definite drift away from HTC’s unique vision. Keeping that from happening with the One series should be the next big concern for HTC.

    oh and i forgot data caps. enjoy running into those more often with LTE and having everything in the cloud.
  • wdb1966 - Friday, May 4, 2012 - link

    Exactly!!!

    On a device specifically targeted to multimedia users, its crazy to NOT have a microSD slot for expansion.

    I hope an engineer somewhere lost their job.

    I would not use this phone even if it were given to me for FREE!

    Samsung S3 is going to launch this week. It's premature to recommend a next generation smartphone without testing the S3, at the very least.
  • dagamer34 - Tuesday, May 1, 2012 - link

    I'll bet you good money that the US version of the Galaxy S III is basically an HTC One XL with a microSD card slot, Super AMOLED+ HD screen, and and 12 MP camera.
  • lowlymarine - Tuesday, May 1, 2012 - link

    Hasn't it more or less been confirmed that the GS3 is going to be using a quad-core A9 of Samsung's own design? Or did you not mean to imply it would use the same Snapdragon S4 SoC?
  • jwcalla - Wednesday, May 2, 2012 - link

    I think I read somewhere that the international version would be the quad-core Samsung A9, but the US version will be a Snapdragon S4. Something about LTE network compatibility.
  • RussianSensation - Wednesday, May 2, 2012 - link

    Well at the very least considering it's launching this week, wouldn't you wait for a test against the S3?

    For starters, the quality of construction already looks better than the HTC One and the screen will be larger.

    Also, if you happen to listen to music on nice headphones the HTC One also falls short:

    All these things already would alone make me want to wait to see how competing new generation Android phones would do.
  • Impulses - Wednesday, May 2, 2012 - link

    You do realize that review is for the Tegra 3 version no? The audio stack and hardware could be completely different on it, the AT&T One X probably shares more in common with the One S since they both run S4...
  • RussianSensation - Thursday, May 3, 2012 - link

    Ya, I know that. There are other issues with HTC One, lack of Micro SD card, smaller screen than S3, worse quality construction most likelyl. Also, the video camera and still camera are not great either, and early benchmarks are showing that the Mali-400 and Exynos 4 Quad chip in S3 will easily beat the HTC One X:

    It won't launch this week. It will be presented this week. Small difference.
