A new firmware with the build number 23.4.A.1.236 has been certified for the Sony Xperia Z3, Xperia Z3 Compact and Xperia Z3 Tablet Compact over PTCRB. This will replace the previous version 23.4.A.1.232. As we see the build number we can expect that this will be a minor bug fix update. Hopefully this looks like a patch for the Stagefright exploit. Last update with the build number 23.4.A.1.232 patched most of the exploits, but this update will patch the one new exploit (CVE-2015-6602). So stay tune with XperiBlog to know when the update rolls.
