Sony Releases Android 5.1 Lollipop Upgrades For The Xperia C4 And The Xperia C5 Ultra

Jan 18, 2016 01:32 AM EST

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.

For the Xperia C4, here are the details of the Android 5.1 Lollipop Update:

-The update is applicable to all Xperia C4 single-SIM and dual-SIM variants, except for the Xperia E5343.

-The build number for the Xperia C4 single-SIM models is 27.2.A.0.155 while the build number for the C4 Dual models is 27.2.B.0.155.

For the Xperia C5 Ultra, here are the details of the update:

-The update will roll out on the single-SIM E5553 and E5506, as well as the dual-SIM E5533 and E5563.

-The build number for the Xperia C5 Ultra single-SIM models is 29.1.A.0.87 while the C5 Ultra Dual SIM models will have 29.1.B.0.87 as its build number.

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.
