Key difference: Xperia J was announced in October 2012 as a cheaper variant of the Xperia T, resulting in the phone sporting a similar design to the T. The Xperia J features a 4-inch scratch-resistant TFT touchscreen that offers a pixel density of 245. Sony Xperia T is Sony's first smartphone built on Qualcomm's Snapdragon S4 platform. It features a 4.55 inch screen with a resolution of 720 x 1280 pixels. It runs on a Dual-core 1.5 GHz Krait Qualcomm MSM8260A Snapdragon with 1 GB of RAM. It features Android Ice Cream Sandwich (v4.0.4) out of the box but is upgradeable to Jelly Bean (v4.1).

Xperia is a well known brand of smartphones that are a part of the Sony Mobile. The Xperia brand was initially a collaboration with Ericsson but has since then been dissolved. Now, Sony has single handedly taken it upon itself to ship out new phones, while maintaining the level of quality and design of the older versions. In order to garner response for its new line of smartphones, the company started marketing the Sony Xperia T as the Bond phone, which is featured in the movie Skyfall. Xperia J is the shy, younger brother of the Bond phone, and is also cheap to boot.

The Xperia J was announced in October 2012 as a cheaper variant of the Xperia T, resulting in the phone sporting a similar design to the T. The Xperia J features a 4-inch scratch-resistant TFT touchscreen that offers a pixel density of 245. The pixel density is the not the best among the contenders, but that does not hinder the high-res display that is visible on the phone. The display shows quite smart and sharp images, with very accurate color representation. The display also has excellent viewing angles and does is less reflective under sunlight.

The design of the phone is also quite similar to Xperia T. The phone comes with a plastic chassis that has a sturdy built. The Xperia J has an arched back similar to Xperia Arc series, which is pleasing to hold and grip. The silver plastic lining that graces the other Xperia series has been shifted to the bottom and acts as a second LED indicator during calls. The phone is also quite light, weighing only 124 grams. The Timescape UI is very similar to the original Google Android UI and basically seems like cheap imitations. The phone has three capacitive buttons on the bottom of the screen, Back, Home and Menu buttons. The buttons are placed on the far bottom of the device, making it more prone for the user to drop the device. The top of the device houses the 3.5mm jack, while the left side has the USB/charging port. The right side of the device is quite busy with the power/lock key on the top right hand and the volume rocker just below the power key.

The device is powered by 1 GHz Qualcomm processor and only 512 MB, which makes the device a little glitch and lagging when trying to shift screens as well as switch apps. The device, when not multitasking and doing basic functions, still lags a little. The device comes with 4 GB of internal space, of which only 2 GB is available to the user. This is very little compared to phones that are offering 8/16/32 and even 64 GB. However, the company has provided a SD card slot that allows users to expand memory by another 32 GB.

The device houses a 5 MP rear camera with autofocus feature. Just above it, a LED flash light can also be found. However, the front camera and the video recording capabilities are a little disappointing. Both, the front camera and video recording are VGA, which does provide the best resolution. The 5 MP camera is pretty decent, but if you have gotten used to the high-res 8 and 12 MP cameras, this camera will not at all be pleasing. The camera takes decent photos, but it isn’t sharp, clear or even HD for that matter. However, the phone does come with juice, 1750 mAh to be exact. This ensures that the phone last a couple of days when not in constant use and at least a full day when working with it all day. The company does offer features such as Wi-Fi hotspot, Bluetooth and USB, but it does not offer NFC capabilities.

The Sony Xperia T is another model by Sony that was released in August 2012. It was one of the first few models that Sony has released after its break-up with Ericsson. It is Sony's first smartphone built on Qualcomm's Snapdragon S4 platform. It features a 4.55 inch screen with a resolution of 720 x 1280 pixels. It runs on a Dual-core 1.5 GHz Krait Qualcomm MSM8260A Snapdragon with 1 GB of RAM. It features Android Ice Cream Sandwich (v4.0.4) out of the box but is upgradeable to Jelly Bean (v4.1).

The phone also has a 13 MP primary camera with a 1.3 MP front camera. The phone is powered by a non-removable Li-Ion 1850 mAh battery. The phone also comes with pre-installed Sony apps called Walkman, and Movies. These are part of a pre-loaded software suite that allows for consuming and sharing a vast library of multimedia content.

Sony Xperia T has gotten very popular as it had been featured as James Bond's phone in the 2012 film, Skyfall. In fact, in some European countries, especially the UK, the phone is actually marketed as the Bond Phone.
