Sony's new Xperia Z4 smartphones are displayed at the company headquarters in Tokyo, Japan. Sony Corp unveiled the new high-end Xperia handset featuring an aluminium frame and a 5.2-inch screen on April 20, 2015. The unveiling is an attempt to show that the company is still in the smartphone race even as it scales down its struggling mobile operations.

Sony Xperia, known for their high-end hardware but the dismal implementation of the Android, has rolled out an Android 5.1 Lollipop update to two Xperia devices, the C4 and the C5 Ultra. According to GSM Arena, the move came as a surprise, because Sony previously stated that the Xperia models’ updates will jump straight from 5.0 to 6.0.

Cynical readers of the GSM Arena announcement for these two updates speculate that because Sony doubled back on their announcement to update these models straight from 5.0 Lollipop to 6.0 Marshmallow, Sony may NEVER release the Marshmallow update and keep the devices on 5.1 Lollipop. These comments were made with the understanding of Sony’s update lifecycle, though, the commenters could be wrong.

As usual, in order to update your Sony Xperia C4 and C5 Ultra, do these steps:

-Log on to the Internet, either via WiFi, LTE, 4G, or 3G.

-Go to: Settings > About Device > Software Update > Choose “OK.”

-Follow the directions from there.

-Check if the software build version matches the build numbers we provided, and you’ve successfully upgraded your Sony Xperia C4 and C5 Ultra to the latest possible version for the device.

If you don’t find the software OTA upgrade available yet, keep checking back in the coming days, as GSM Arena has pointed out that the update may roll out in stages. Hopefully, the commenters are wrong, and Sony will still upgrade these units to Marshmallow as Android Marshmallow has features that may prove absolutely useful, such as the capacity to choose through the permissions to approve with apps.
