Sony Xperia SP has a new firmware certified by PTCRB having the build version 12.1.A.1.207. Unfortunately, the newly certified software is still running Android 4.3 Jelly Bean based on the numerical coding. Android 4.4.2 KitKat remains under investigation at Sony Mobile software pages.

Newly Certified Firmware for Xperia SP

Sony Xperia SP users worldwide may expect another firmware update coming soon after PTCRB posted a newly certified software version for the smartphone. It has the build version 12.1.A.1.207 and seems like an incremental upgrade to the latest 12.1.A.1.205 firmware build based on the numerical changes.

It is compatible with Sony Xperia SP C5302, C5305 and C5306 variants. However, this newly certified firmware is still running Android 4.3 Jelly Bean by comparing its code to the previous version.

There are no details yet on what Sony Mobile features on this firmware, but since it is an incremental upgrade, expect bug fixes, app optimisations and other system enhancements.

Current Firmware Version

For those who haven't updated their Sony Xperia SP smartphone, Sony Mobile offers Android 4.3 Jelly Bean 12.1.A.1.205 at this time, according to its official software support page. It can be downloaded via OTA, Sony PC Companion for Windows PCs, Sony Bridge for MAC or Software Update Service.
