What's in the Box
HTC One X handset, charger, USB cable, quick start guide

Android Ice Cream Sandwich Operating System

The HTC One X runs the Android 4.0 operating system (dubbed Ice Cream Sandwich), which adds powerful new ways of communicating and sharing while improving on the best Android features: easy multitasking, rich notifications, customizable home screens, resizable widgets, and more.

The new Ice Cream Sandwich interface features an onscreen navigation bar that replaces the hardware buttons for Back, Home, and Menu found with older Android-powered phones. And with Google+ integration, you can video chat with groups of up to 9 friends as well as easily upload and share photos and videos. Other features include:

Face Unlock

You can now unlock your phone with just your face using the Face Unlock option. It takes advantage of the front-facing camera and state-of-the-art facial recognition technology to register a face during setup and then to recognize it again when unlocking the device. Just hold your phone in front of your face to unlock (or use a backup PIN).

And the lock screen now lets you do more without unlocking. From the slide lock screen, you can jump directly to the camera for a picture or pull down the notifications window to check for messages. When listening to music, you can even manage music tracks and see album art.

Home Screen Folders

Quickly access related apps right from the home screen by organizing apps and shortcuts into folders--just drag one app onto another to create a folder.


Multitasking is even easier and more visual in Android 4.0. The Recent Apps button lets you jump instantly from one task to another using the list in the System Bar. The list pops up to show thumbnail images of apps used recently--tapping a thumbnail switches to the app.

Voice Input

The new voice engine in Android 4.0 lets you dictate the text you want, for as long as you want, using the language you want. You can speak continuously for a prolonged time, even pausing for intervals if needed, and dictate punctuation to create correct sentences. As the voice input engine enters text, it underlines possible dictation errors in gray. After dictating, you can tap the underlined words to quickly replace them from a list of suggestions.

AT&T 4G LTE Network

AT&T's 4G LTE network allows for quicker access, smoother media streaming, and faster web experiences. LTE technology is capable of delivering mobile broadband speeds up to 10 times faster than 3G. Additionally, LTE technology offers a faster response time due to lower latency--the processing time it takes to move data through a network--vastly speeding download times for web pages as well as improving services such as mobile gaming and two-way video calling.

By the end of 2011, AT&T plans to launch its 4G LTE network in 15 major metropolitan areas, covering at least 70 million Americans. Coverage will continue to expand in the next few years and is planned to be largely complete by the end of 2013.

And when combined with 4G HSPA+ technology, AT&T is capable of delivering a quicker, more consistent mobile broadband experience than ever before. AT&T has deployed HSPA+ to virtually 100 percent of its mobile broadband network, which enables 4G speeds when combined with enhanced backhaul (via Ethernet or fiber). Backhaul is one of the major pieces of a telecommunications network. Think of it as the limbs connecting AT&T's cell towers with AT&T's backbone network that provides access to the Internet.

5.0 out of 5 stars stop whining about locked bootloaders! May 13, 2012
By C. Wang
I'm tech savvy, but I am also aware that 99% of the users will never bother boot loading their phones, and it's not fair to see the complaints of the remaining 1% occupying 50% of the reviews here, making this excellent phone seem utterly worthless.

Now, for the remaining 99%:

I like new phones, and I've recently moved from a iPhone 4 to Galaxy SII, now to this HTC One X.

First of all, the screen is gorgeous. I loved the Retina Display on the iPhone, and although the Galaxy SII has a vivid OLED display, the resolution is significantly lower, and is further worsened by the larger screen. After getting used to the iPhone 4, I simply can no longer stand pixelation when reading! Another thing about the Samsung OLED is that the color looks a lot more saturated than normal. Therefore the pictures simply look inaccurate - a "normal" looking picture on the phone looks washed out on the computer, and a color-balanced picture on the computer simply looks too saturated on the phone. The HTC One X has a color-accurate IPS screen (so does the iPhone 4), but at the whopping 1280x720 resolution (compared to 960x640 on the iPhone). I simply cannot see how anyone will claim this screen is worse than the iPhone's. HD video simply looks amazing on it.

Did I mention HD video? Youtube HD looks great, but the phone does get a bit hot, and drains quite some battery when doing so. The screen is bright enough for usage under sunlight, but does drain more battery. The screen itself can account for >50% of power consumption. Without watching video, I can get a full day of normal usage with about 30% battery left at the end of the day. But if you are one of those who isn't always on your phone, 10 hours of stand-by drains the battery by only 10% (no kidding! I tried that today).

5.0 out of 5 stars Great Smartphone - six year smartphone user May 17, 2012
Been using smartphones for last six years including blackberry, windows, and tons of iphones. But this is my first Android phone. Finally decide to try something new to replace my iphone4. Ice Cream Sandwich has a huge improvement from the last time research android phones three years ago. So far this phone is doing everything very well compare to my old phone.

Android has the Google Play store where you get apps, music, movies, etc. I tried out all built-in apps and they all work well except a few I didn't like. The HTC keyboard app is too crowd with options. Download the ICS keyboard. I didn't like the built-in web browser that much. Download the Chrome Beta. Chrome will be the default web browser on the next major Android update. The Chrome browser works just like the iphone one. All pinch-zone, double tap, and other gesture work. I set up the built-in mail apps, gmail, and yahoo to sync with my work Exchange mail and personal accounts. Only complaint is it doesn't have pinch to zoom on the email app for whatever reason. Not a big deal.
Calendar and contacts sync up up fine. All other apps Clocks, Alarms, Youtube, Google Maps, Music/Video player, Gallery, and Camera work very well.

The phone performs very fast. I played some HD 720 videos and it was fast and beautiful. Internet LTE speed is super fast like 30mbps per second. BTW, amazon only offer the 3 GB 30 dollar plan. I had no issues calling ATT after activation to swap it out and put the 15 dollars 200 MB LTE dataplan to save money. I have wifi at home and work.

The operating system is very easy to learn. You should feel right at home after a few hours. Also, search google if you want to learn how to do something. Android is very customizable.

3.0 out of 5 stars AWESOME PHONE! August 9, 2012
Update 9/23/12: I just downgraded my review of this phone from 5 to 3 stars for two reasons:

1. Battery life is worse than advertised and battery is non-replaceable.

2. This phone does not have an SD card slot and only about 8GB of space is available for storage. I knew this when I bought it, but wasn't concerned because the AT&T sales rep who sold me the phone in an AT&T store showed me in the HTC USER MANUAL where it comes with 23GB free space on dropbox (for two years), and dropbox is integrated into the latest HTC Sense operating system.

According to the manual, after setting up dropbox, photos and videos are automatically uploaded to dropbox after capture. Had also read several reviews that mentioned HTC was doing this due to the lack of an SD card slot. So when I recently started running out of space after several minutes of HD videos (one of the phone's best features) I went to claim my 23GB free space on dropbox (supposedly automatic after completing the "getting started" steps). But it was not to be. HTC & dropbox now say that AT&T is "not participating in this promotion" and only the 2GB free storage is available (with a little more if you jump thru dropbox hoops and invite friends, etc.).

The problem is that the user manual says NOTHING about any "promotion" or required carrier participation. The dropbox storage is depicted as a feature of the phone in the user manual (even the manual currently on the AT&T site), which makes sense due to the miniscule and non-upgradeable on-board memory. And now I see that AT&T is offering a competing online storage plan that you is PAY after 5GB. Maybe that's the reason AT&T?
