We’re excited to announce the release of the Xperia™ ion, the first LTE smartphone from Sony in the U.S. and carried exclusively by AT&T. And it has all the features that developers and users alike have been looking for in an Android™ smartphone – 1.5 GHz dual core processor with Qualcomm Snapdragon S3 Mobile Processor, 1 GB RAM, a 4.6-inch, 720×1280 resolution reality display, 12 MP camera with Exmor R™ mobile sensor, NFC, and much more!

Our first LTE smartphone in the U.S.

The new Xperia™ ion is Sony’s first LTE smartphone released to the U.S. market and only available through your local AT&T retail store. Xperia™ ion runs on the Android™ 2.3 (Gingerbread) operating system though an official upgrade to Android™ 4.0 will be released later). In order to provide 4G LTE connectivity, Xperia™ ion includes a Qualcomm Mobile Data Modem™ (MDM™) 9200 chipset. The MDM9200™ is the industry’s first integrated multi-mode, single-chip 3G/LTE solution and supports both FDD and TDD modes of Category 3 LTE configured for the AT&T LTE network. In Xperia™ ion, the modem has been configured specifically for the AT&T network.

Also, it’s the first phone from Sony Ericsson supporting Category 14 HSPA+. This means great data rates, whether you are on HSPA+ or LTE. Xperia™ ion also supports five different radio frequency bands, namely LTE 700MHz and 1700MHz, and UMTS HSPA+ 850MHz, 1900MHz and 2100Mhz.

Top key features: Dual core processor, Adreno 220 GPU, OpenGL

Inside boasts a 1.5 GHz Qualcomm Snapdragon S3 MSM8260 dual core processor to deliver great battery life and stunning, fluid graphics. This is further supplemented by an Adreno™ 220 GPU, which provides an enhanced level of 3D graphics performance, allowing for high-end, immersive gaming experiences previously limited to PCs and game consoles. The Adreno™ 220 GPU also supports a number of APIs, including OpenGL ES 2.0, OpenGL ES 1.1 and OpenVG 1.1. For more information on OpenGL, see our previous OpenGL blog post.

Other key features: Mobile BRAVIA engine, NFC, GLONASS, ANT+

Another key feature in Xperia™ ion is the Mobile BRAVIA® Engine, which delivers superior image quality for photos and videos. Images are sharper, contrast is boosted – darks are darker and whites are whiter, and noise is reduced. Xperia™ ion is also NFC enabled, allowing you to share content with other NFC devices and enjoy an increasing number of NFC applications and services, as well as Xperia™ SmartTags. Xperia™ SmartTags are a new kind of accessory that can launch a number of pre-configured profiles in the phone. Another connectivity feature includes GLONASS global satellite detection, which allows greater positioning accuracy when the device is using navigation-related applications. You’ll also find ANT+, which is an interoperability function that enables the collection, automatic transfer and tracking of sensor data for monitoring of personal wellness. Stay tuned to Developer World for more in depth information about the LTE, NFC and GLONASS going forward! For our current information on ANT+, check out these ANT+ blog posts.

    How to switch to LTE Only mode in Sony xperia ion lt28h?

  2. By Michael Cohan


    I live in a very strong area for the 1700/2100 LTE Basebands for T-Mobile and bought this phone unlocked for $130 a few weeks ago. I had a Galaxy S2 with Sprint and this feels like that on steroids because I upload at 40Mpbs, download at 30 MBPS, and Sony has to be user friendly phone manufacturer out there. I have a little bit of developer experience, but have been married to Samsung since 2010 before I got this to carry in my pocket instead of the Note 3 and otterbox I normally lug around. I pay insurance on my main phones, so would never root/unlock via XDA, even though I trust them and they do amazing things. I bricked this phone 10 days ago off a bad GAPPS version to go with a non-stock Kit Kat 4.4.4 and it was literally a waiting game until today. XDA was right about everything, I downloaded all of the freeware I didn’t have needed. Then I saw that Sony not only has, but supports Flashtool, Flashboot, gave me a free unlock code because Flashtool said it relocked. Sony Companion ended up fixing it after the dozen or so hours I took to learn. The only downside to this phone, and I may be wrong, is that the lt28at variant seems to be very lacking compared to the lt28i in terms of support. I do not believe a Jelly Bean 4.1.2 stock kernel ever made it to this phone and the comfort of using all Sony software and firmware to flash/update would feel much more reassuring after what I went through. The Z3 has to be an amazing phone given I am only operating with 1GB of RAM and this phone is Superior to anything out before the S4/iPhone 5 model which came out over a year later

    Anybody please tell me If I bought a LT28at/LT28i from US then will it work in Indian network on 2g/3g ? Unlocked version.
    Please reply.


    • By Rakeshkumar Patel


      definately it will works,, Condition its must be unlock version from US, so all sim Indian will works.

      Advantage– on 3G network of service provider,, it gives your 4 G speed of browsing due to special modem inbuilt.

      i have and its definetly amazing…………


      You will not able to get 2G network and data,, as its not supporting switching of network………

      Must be 3G and above,, works like better than IPhone 5,,.. I tested and comparision,, More more faster than Iphone.

      Hi Ms Prasool,
      If the LTat/LT28i (Xperia ion) is unlocked, you should be able to use it in India.
      Thanks and best regards,

    When is the Xperia Ion going to be upgraded? Is that in the works still? I kinda feel like you guys forgot about it….

  9. By Troy Peralta


    According to site, the AT&T Sony Xperia ION supports 3 LTE bands: 700/1700 & 2100Mhz – the latter is supported in Canada, while Verizon Wireless in the USA supports only the 700Mhz bands.

    Can Sony staff please confirm these are the bands that Xperia ION supports please? If so & if true this would be an interesting choice INDEED!!

    • By Joe Padre


      Hey Troy,
      For Xperio ion, LTE bands supported are LTE Band IV and Band XVII.

    Erm…since the Xperia S and Ion share the same features..Why didn’t put an micro SD slot for the Xperia S. Since it is high end smart phone…The developer should known that a good smart phone need larger storage to keep the video, games, and other software. Please pay concern on the comment of consumers because they are source of financial support to ur company. In other words, u will be down without us.
