With a new flagship phone in tow, the HTC One X delivers the goods as its sports the most up-to-date versions of Android and its very own HTC Sense UI. Actually, there’s nothing different with this version, since it’s an exact facsimile to the international version – though, the preloaded apps differ. As every self-respecting smartphone nowadays, the HTC One X runs Android 4.0.3 Ice Cream Sandwich. This latest version of the OS bears tons of improvements in almost every aspect of the system, including the UI, the browser, the core apps, performance and so on. Still, you won't get to see a thing of the ICS interface, because HTC has personalized it heavily with the new Sense 4 UI. We won’t be going into the details here, but if you’re curious, you can read more about it in our review of the international HTC One X.


The main goal for HTC in terms of the interface has been to simplify it. Indeed, previous versions of the UI had so much options and personalization stuff, that it could easily throw the more inexperienced users into confusion. Indeed, we do find Sense 4 to be significantly streamlined. Well, you still get the characteristic weather clock and big widgets, taking up a whole homescreen page, but HTC wanted to remain recognizable among the ocean of Android handsets on the market. However, gone is much of the eye-candy that was present in the previous version of the software. For example, you no longer get the spinning carousel when you energetically switch between homescreens.

The main menu is also different now – the apps are arranged in a 4x5 grid pages, which are scrolled horizontally, instead of vertically as in previous versions of Sense. The new experience is probably simpler this way. The good thing for us is that the handset is moving pretty swiftly now, with no hint of lag or choppy animations. We're not sure how much of this is to be attributed to the optimizations done to the interface, or the Snapdragon S4 processor, but anyways – the result is a perfectly smooth UI, and that's what we care for.

Without question, the HTC One X is easy on the fingers when it comes to typing up messages with its on-screen keyboard – though, its set of directional keys seem to clutter things up. Of course, we’ve always been fond of the Sense keyboard, seeing it provides us with some numbers and punctuations directly from the main layout by performing a long press. Consistently typing at a fast pace isn’t a problem, but we sorely wish for those directional keys to disappear entirely, so that the layout can be spaced out more.

Of course, every way of using email known to humankind is available on the HTC One X. In addition to custom POP3/IMAP accounts, you can also easily set-up Exchange ActiveSync, Gmail (now, that's a surprise!), Yahoo! Mail and Microsoft Hotmail.

Processor and Memory:

Upon hearing about the switcheroo done on AT&T’s version of the HTC One X, some were bummed to find out that it would not be powered by the same quad-core CPU in use with the international one, and instead, it would be outfitted with a 1.5GHz dual-core Qualcomm Snapdragon S4 processor with 1GB of RAM. Well people, there’s no cause for alarm, because seriously, it performs equally to its quad-core sibling. Specifically, it maintains a steady amount of responsiveness with a variety of basic and complex operations, and to tell you the truth, it barely exhibited any strain or lag during our testing. Still not sold by its processing prowess? Well, you’ll be surprised to know that the benchmark results are quite positive, since it obtains scores that are deemed as above average.

Seemingly becoming a standard of some sort with today’s premier Android smartphones, the HTC One X lacks a microSD card slot, which means you’ll need to be more careful with the 9.93GB of free storage that’s available out of the box. Meanwhile, there’s another 2.21GB strictly reserved for apps.

Internet and Connectivity:

For something so awe-inspiring in many ways, we’re a bit perturbed by the web browsing experience – again, much like what we saw previously. Actually, we’re absolutely thrilled that AT&T’s beauty is bearing support for LTE connectivity, which results in vastly superior data speeds over its HSPA+ only sibling. However, just like before, we’re baffled by the experience, as it seems to be clunky with its layout and performance. Specifically, the top and bottom menu bars containing the back button, address bar, “Add to”, “Bookmarks”, “Saved for later”, and “Tabs” all seem to disappear and reappear at random. Furthermore, the same constant blinking action happens whenever we pinch zoom or double-tap-to-zoom. Putting those meddling issues aside, the browser for the most part performs swiftly – even when it encounters Flash content. Still, we come across some delays and choppiness every now and then with its operation.

As we’re clearly mentioned, this version is packing support for AT&T’s 4G LTE network – and boy is it lightning fast! In fact, we’re able to get maximum download and upload speeds of 20.2 Mbit/s and 21.47 Mbit/s respectively while testing it out in the heart of New York City. In addition, it features aGPS, Bluetooth 4.0, 802.11 a/b/g/n Wi-Fi, NFC, and mobile hotspot functionality.
