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,

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

USB-OTG
support. An illumination bar at the bottom of the phone can change color to adapt to the color rendered in the screen while using the album and walkman apps; third-party apps can be downloaded to change the colour. The phone uses a removable "BA600" Sony battery which has 1290 mAh.

Software

The Xperia U was originally released with Android 2.3.7 Gingerbread, but, on 28 September 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 17 December 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.[4]

Various unofficial updates are available on

rooted
phone.

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. The illuminated strip is used on custom ROMs to show notifications since the notification LED
of the phone is too dim to be really noticeable.

Reception

Xperia U generally received a positive response from critics with some calling it as a budget version of

weasel words] 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."

Storage

The Sony Xperia U has 8 gigabytes of internal storage. 4 GB are available to the user and are internally handled by the phone like an SD card. 2 GB are reserved for the Android OS, and the remaining 2 GB are used for downloaded apps. The phone supports MTP, but this can unofficially be changed on rooted phones so that the 4GB are accessible from the computer like an SD card.

USB-OTG is also supported with separately-sold adapters. Some custom ROMs support file systems like NTFS for this storage, so large external hard drives can be used with the phone too. USB mice and keyboards are also supported when connected with an adapter.
