The Xperia Z Ultra has Android 4.2.2 Jelly Bean, enhanced with the custom modifications by Sony. The basic option for multiple home screens is present here too, though the range is between 5 and 7 home screens, not that much in the offering. Adding content is also consistent to Android defaults, using tap and hold or the pinch to zoom option – these can be used in case users want to add widgets or shortcuts on the home screens. The moving of shortcuts / widgets by tap and hold on the shortcut / widget and then moving it around is also consistent.
Sony has provided some custom widgets for services, which make the device look more Sony. Notification contains Sound, Bluetooth, Wi-Fi and Brightness by default, though more can be added. Google Now is also implemented, with its own set of features available for the user’s ease. We noted that the Xperia Z Ultra’s large display lets users get the most out of this option.
The FM radio is available on the device, with the ability to ID the track being played on the radio, as well as the option to post a status on Facebook. The FM this time around is much more stable than with previous devices from Xperia. Many themes also make the user interaction and device display more appealing to users.
The calendar and notes control is pretty standard, though users can create handwritten notes as well. The background, text color etc can be set for notes. There is also the option to integrate with Evernote. Sony also has a Backup and Restore app, which can utilize the memory card, the internal storage or attached USB devices as well to backup or restore. Backups can be made of the apps, respective data of apps as well as any other files, media or otherwise.
The Google Chrome is the degault browser for Xperia Z Ultra, refined to a decent level by Google. Tab switch, resize is all standard, though the tabs can be arranged pretty neatly on this device. Also, the browser sync feature of Chrome allows users to be able to sync their browsing session between the device and PC, creating a more catchy experience. Another new feature, the Reduce data usage lets chrome compress the webpage to display minimal data from the URL, while keeping the full functionality of the site.
The Xperia Z Ultra has Office Suite 7 by default, which makes document view that much simpler. Plain text files, along with Word, Excel, PowerPoint and PDF files can be viewed, though for edit capabilities, the Pro version is to be purchased.
