Signature features
Xperia™ go comes with a range of Xperia™ features as standard. Below is a summary of the key
signature features.
Xperia™ Timescape™
Communication made easy
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.
