Product overview
Xperia™ ray
Sleek and irresistibly elegant with a clear vibrant display, the Xperia™ ray combines compactness with
high functionality and style. Here’s a summary of the main features:
•Elegant smartphone with aluminium frame, mineral glass – and only 9.4mm thin
•Great stills and videos even in low light with Exmor R™ for mobile
•Reality Display with Mobile BRAVIA® Engine
•Fast, powerful smartphone with all the apps you need
9.4mm thin
Just 9.4mm thin and 100g light, the Xperia™ ray can fit neatly into the palm of your hand, or slide
comfortably into a small shirt or jeans pocket. Its flat aluminum frame adds further grace and style. But it’s
got more than just good looks. The Xperia™ ray combines the best of Android with the latest goodies
from Sony Ericsson.
Vibrant visuals
The Xperia™ ray delivers HD video and 8.1 megapixel photo capturing. Capture exceptionally clear
photos and videos even by candlelight with Exmor R for mobile, a back-illuminated CMOS sensor that
uses light more efficiently than conventional front-illuminated pixel technologies. Mobile BRAVIA ENGINE
further enhances the visual experience, combining magically with the scratch-resistant mineral glass and
3.3 inch Reality Display. The black screen finish cuts down on light lost through reflection, resulting in a
clearer image. And if that’s not enough, you get to browse the web in FWVGA resolution.
Power to go
The Xperia™ ray’s durable 1500mAh battery combines with the pre-installed power save mode
application to give you up to five times more staying power. So you can chat, watch videos and enjoy your
music for as long as you want.
Grow with Android Market
With the Android Market application installed as standard on your Xperia™ ray, you can easily download
everything from games to everyday tools and entertainment apps. With more than 200,000 apps available,
there are thousands of ways to personalise your life.

Sony Ericsson signature features
The Xperia™ ray comes with a range of Sony Ericsson features as standard. Below is a summary of the
key signature features.
Sony Ericsson 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 dif-
ferent applications to see what's going on.
Sony Ericsson 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.
Sony Ericsson Sync™
Your mobile life on the web
Synchronise your phone data using Sony Ericsson Sync so that you always have a backup. While you’re
at it, match your phone contacts with your Facebook™ contacts. All your synchronised phone data is right
at your fingertips and in your account on www.sonyericsson.com.
Sony Ericsson Local connectivity
More control over your media
Using Sony Ericsson Local connectivity, you can exercise more control over how media files get trans-
ferred and stored. For example, you can select MTP mode to transfer files if you want to limit the risk of
data corruption or select MSC mode if you want to have more control over the data storage.
Sony Ericsson 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.
Note: Some of the services mentioned above may not be available in all markets.

* Applications from the Android Market™ vary widely in size, from less than 100 KB for small utilities to 3-4
MB for full games, music player applications, or other major offerings. The average size, if a representative
selection of useful and fun applications is selected, is about 1 MB. This means that, on average, more than
100 applications can be downloaded and used on your device without negatively impacting performance.
With the ready availability of the Android Market™ application in the phone, it is also very easy to delete
and later reinstall infrequently used applications.
