Sony is following up the recently launched 10.1.1.A.1.253 firmware for the Xperia Z and Xperia ZL with another update. Firmware build 10.1.1.A.1.307 has just been certified for the Xperia Z (C6602, C6603) and Xperia ZL (C6502, C6503, C6506) on the PTCRB website.
The ’253′ Android 4.1.2 Jelly bean update brought a number of improvements including the white balance app for the Xperia Z, UI changes and camera/performance enhancements. We expect the latest ’307′ update to bring some bug fixes and could be one of the last updates before we see Android 4.2.2 make an appearance.
