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.

It was revealed in late 2011 that Sony Ericsson was working on the ST25i, and on 20 January 2012 a photo of a development model of the phone, codenamed Kumquat, was leaked. On 23 January, its name was revealed as Sony Xperia U. 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.

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(split into 392MB system memory and 120MB for the GPU), 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 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.
