Sony has quietly outed a new firmware update (version 14.4.A.0.133) for Xperia Z1 (C6903) users on Vodafone carrier network in Germany. Being a minor carrier-specific update, it is apparently aimed to fixing trivial bugs and stability-related issues that were obviously overlooked in the previous update (14.4.A.0.118). You can download its FTF file via the direct download links given below and flash it manually using the latest version of Flashtool.
