Xperia 1 Gets First Firmware Update (55.0.a.2.278) Adding June 2019 Security Patches



Xperia 1 gets first firmware update (55.0.A.2.278) adding June 2019 security patches

Sony Mobile is rolling out the first firmware update for its new flagship, the Xperia 1. The update moves the build number from 55.0.A.2.205 to version 55.0.A.2.278, moving the Android security patches from April 2019 to June 2019 in the process. The update is live on both single SIM and dual SIM variants.



Frustratingly, Sony continues to think that no changelog is necessary for its smartphone updates, when pretty much every other manufacturer provides one. This remains the case with the Xperia 1, so we don’t know what other changes have been included.

Sony – if you are listening, then providing a changelog is a general courtesy to your customers, and the transparency over what users are upgrading to should be provided with every firmware update, even if just a bug fix. Your customers want to know.

We imagine the update includes some bug fixes and performance improvements. Sony were promising camera updates, but we can’t see any evidence of this. The ability to take 21:9 pictures for example is still absent. If you have updated, please let us know any changes you’ve noticed in the comments below.

Thanks azzido, mortael and Sebastian!
