Right now, everyone is expecting to hear news about the devices that will get Android Marshmallow as not many devices are currently running this version of the operating system. Sony has never been among the fastest manufacturers to release updates for their handsets, but they update many devices in their portfolio to newer versions of the OS. There are different approaches to updating a device into a new version of Android, one might be to periodically update it with almost every update that gets released and another one would be to skip a few versions only updating it to major versions of the OS. It seemed that Sony would take the latter approach in a few of their devices, but this week, it was reported that the company has updated the Xperia C4 to Android 5.1 and now, the update is being rolled out to one of the most unique looking phones of the company, the Xperia C5 Ultra.
The Xperia C5 Ultra is a mid-range device, but its 6-inch display barely has any bezels on its sides and the front also includes a large 13-megapixel camera with LED flash. The Xperia C5 Ultra with model number E5553 and E5506 are getting updated to firmware version 29.1.A.0.87 and the Xperia C5 Ultra Dual with model number E5533 and E5563 is being updated to version 29.1.B.0.87. Android 5.1 was released a while ago for their flagship models, and it is currently running on the majority of their handsets. It contained improvements to the volume controllers, additional control options built into the shortcuts of WiFi and Bluetooth from the Quick Settings menu, a few UI changes such as new icons in the Settings menu and additional themes and other enhancements.
Users will receive this update OTA, so they should expect the notification any time now, but if they want to manually check for it, they could go the Settings menu, go into the About Phone section and tap Software Update. Let's remember that this kind of updates is usually rolled out in phases and it might not be available in every region at the same time.
