Product overview

Sony Xperia™ U – Powerful and personal

Get yourself a front row seat. Enjoy the sights and sounds of your favourite films and music bombarding

your senses. On Xperia™ U’s razor sharp Reality Display, and in 3D surround sound. Snap photos fast,

film videos in super-sharp HD, and share them with your friends in a flash. Enjoy it all with super quick

performance powered by a dual core processor. Let the true you shine through with super snazzy

coloured bottom caps and a transparent band that changes colour to suit your themes, photos and album

art.

Made for movies

Watch every moment from every movie in crystal clear colours. See every smile from last year’s party in

true detail. Sheer video magic on the 3.5” Reality Display with Mobile BRAVIA® Engine. And with a dual-

core processor at its heart, you’ll enjoy super-fast performance whether surfing the web or enjoying the

latest Hollywood blockbusters from Sony Entertainment Network.

Don’t miss the hit

Watching volleyball on the beach? Capture the smash, not the sand. Fire up the camera. Fire off the shots.

From sleep to snap in just over a second. And with 5 megapixels and face detection you’ll shoot that

winning smile. Fancy something more moving? Why not film the whole tournament in razor sharp high

definition?

Live the sound

Start your own sing-a-long. Download that summer playlist. Enjoy it all in crisp and loud sound with xLoud

and 3D surround sound Sony audio technology. Plug in your earphones, sit back and listen, as the deep

bases and high trebles shoot around your head.

Add some shine to your life

Watch the transparent band light up your life. It reflects your favourite artists’ album arts with matching

colours when you browse through your music, and changes to match the shades in your photos. Or why

not choose a theme that matches the exchangeable cap? Then you'll see the transparent band light up in

the same colour when you receive a call.

Signature features

Sony Xperia™ U comes with a range of features as standard. Below is a summary of the key signature

features.

Xperia™ Timescape™

The place to meet your friends

The Timescape™ application manages all your communication with one person in one place. You can

effortlessly browse by category your Facebook™, Twitter™, email and text communications, as well as

view your photos. Now everything is all together and in chronological order, so you don't have to open

different applications to see what's going on.

Xperia™ Infinite button

Everything you want – from everywhere

Tap the infinite button in the Timescape™ application and smart filter each category of communication by

person. For example, when viewing a text message from a friend in Timescape™, tap the infinite button to

view a list of all chat messages with that friend.

Xperia™ Local connectivity

More control over your media

Using Xperia Local connectivity, you can exercise more control over how media files get transferred and

stored. For example, you can select MTP mode to transfer files if you want to limit the risk of data corrup-

tion or select MSC mode if you want to have more control over the data storage.

Xperia™ Home screen application

The place you call Home

Customise your Home screen with widgets, shortcuts, folders, themes, wallpaper and other items.

Where’s best for you? Email top right? Music player bottom left? You decide. With four extensions to your

Home screen, you’ve got plenty of space to put things where you want. Just remember to flick left or right

to find them.
