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.
