The PTCRB website issued certification for a new firmware early today, namely 14.4.A.0.157 for the Xperia Z1, Z1 Compact and Z1 Ultra that boosts the current OS to a later version of Android 4.4.4 KitKat. The same build started rolling out to the Sony Xperia Z1 compact smartphone in parts of Europe and Australia hours later. The Z1 C6902 is witnessing the roll out in parts of Asia and Italy.
We are anticipating the same firmware to come for the C6902, C6903, C6906, C6802, C6833, C6806, C6843 and D5503 smartphones. You can verify the model number of yours by turning the device on, navigating to the Settings followed by About Phone and checking the model number.
Countless users are complaining about camera quality and there’s hope that this newfangled version does offer relief. It’s three months since the Japanese phone-maker offered any relief for the users so we are hoping it is inside this build number. It is only a minor update and we have no change-log yet. Please leave a comment with what you find after updating. We know it will come with several bug fixes and likely update a few of the Sony native applications. We predict at least one more upgrade coming the way of these handsets before the Android 5.0 Lollipop. Lollipop is delayed until the 12 of November for the nexus range in any case according to the latest reports. Don’t expect the candy version coming anytime soon.
Furthermore, you can back up the smartphones before updating using apps such as Helium for Android. Those of you with root access will need to revert back to stock software until you will start seeing OTA or Update Centre notifications. In the rare event that you do see the notification appearing with the unlocked system internals, you want to ignore it since it can soft-brick the device if you are using a custom ROM.
