The Sony Xperia U ST25i (ST25a in the United States), codenamed Kumquat during its development, is an Android smartphone from Sony. It was launched at the 2012 Mobile World Congress held in Barcelona, and is the second Sony-only branded smartphone after Sony acquired Ericsson's stake in Sony Ericsson in January 2012. The Xperia U has a 3.5-inch (88.9 mm) touch-screen with the mobile BRAVIA engine which optimises the picture, a 1 GHz dual core processor, a 5 mega-pixel rear camera, 0.3 mega-pixel front camera, 512 MB of RAM, and 8 GB of internal storage. The cap at the bottom of the phone is interchangeable. The phone is shipped with four caps: pink, white, yellow and black.
Development
It was revealed in late 2011 that Sony Ericsson was working on the ST25i,[1] and on 20 January 2012 a photo of a development model of the phone, codenamed Kumquat, was leaked.[2] On 23 January, its name was revealed as Sony Xperia U.[3] This was one of the first phones to drop the Sony Ericsson brand in favour of Sony, as, on 16 February, Sony finished buying out Ericsson Mobile Communications's share of Sony Ericsson and renamed the brand Sony Mobile Communications.
The handset was introduced in Barcelona on 28 February 2012 before the Mobile World Congress in the United Kingdom in March 2012 and was released worldwide on 15 May 2012.
Hardware
The capacitive touchscreen display measures 3.5 inches with a resolution of 854 x 480 and a pixel density of 280 pixels per inch. It supports multi-touch: up to 4 fingers, features High Definition Reality Display with mobile BRAVIA engine from Sony, and is capable of displaying 16,777,216 colours. The camera has 5 megapixels and is capable of recording video at 720p High Definition. Its front-facing camera is 0.3 megapixels. The device features a STE Nova Thor U8500 1 GHz dual core processor, 512 MB RAM, Mali-400 GPU, 8 GB of internal storage (4 GB of which is available to the user) and a micro-USB connector with USB-OTG supported.
Software
The Xperia U was released with Android 2.3.7 Gingerbread, but, on September 28, 2012, Sony released an update to Android 4.0.4 Ice Cream Sandwich. Users can choose to keep the Gingerbread operating system, or, using Sony PC Companion or Bridge for Mac, they could upgrade to Ice Cream Sandwich; however, downgrading to Gingerbread is not officially supported. The Xperia U is fully Facebook integrated and features Sony's Timescape UI. It is connected to the Sony Entertainment Network, allowing users to access Music & Video Unlimited in some parts of the world. The Sony Xperia U is also DLNA certified. On December 17, 2012, Sony confirmed that the Xperia U will not be updated to Android Jelly Bean 4.1 due to hardware incompatibility. Sony later reported that the Xperia U was not updated due to the lack of RAM..
Design
Over 95% of the Xperia U front is composed of the display portion, and the back is curved slightly for comfort like on the Xperia S and the Xperia P. It has transparent strip with an illuminated light bar at the bottom, which illuminates when the user taps a button, or when viewing pictures or music by picking up the dominant colour in the picture. It has an exchangeable bottom cap below the illuminated strip.
Reception
Xperia U generally received a positive response from critics with some calling it as a budget version of Xperia P and Xperia S. Critics praised the Xperia U for several features, such as its dual core processor, high quality display, and 5-megapixel camera, but criticized it for the lack of external storage and not having Android Ice Cream Sandwich pre-installed. Natasha Lomas of CNET gave the phone 4 out of 5, saying that "for Android lovers looking for a budget smartphone for dainty snacking on apps and mobile websites, the Xperia U is a worthy contender. It fits the budget and is cheerful, cute as a button and – provided you're not too demanding of it – fleet of foot."
Memory
The Sony Xperia U comes with 8 GB of phone memory and 4 GB of accessible internal storage.
