Update Sony Xperia Z3 D6603, D6653, D6643 To 23.4.A.0.546 Android 5.1.1 Firmware

Sony took a very long time to update its flagship device Xperia Z3 and its siblings to update to Android Lollipop. While Sony was delaying this update, it disappointed a lot of users as it was not the Sony style this time. Sony has always remained pretty much concerned with the software updates. Sony finally broke the silence and started rolling out the Android 5.0.2 Lollipop update for its flagship Xperia Z3 in March, 2016. It looks like Sony has taken a notice of user’s feedback and didn’t want to make them wait longer for the next update. The Android 5.1.1 Lollipop update has started rolling out for our beloved Sony Xperia Z3, Xperia Z3 Compact and Xperia Z3 Compact tablet now. It took a gap  of only 4 months for Sony to cook this update which makes it look like Sony is going to be good to its users once again.

The update carriers some minor changes. These changes include a new message sending animation in the messaging application, a new dialer, new icons in settings application, new launcher settings, numerical keys on keyboard, some icons (WiFi and Bluetooth) in the status bar, sound quality has improved and camera captures the images faster now. This update carries the build number 23.4.A.0.546 and as mentioned it carries the Android version 5.1.1 Lollipop. As of now, this update is on a slow roll out and will take some time to reach out all the regions. If you’re an Android enthusiasts, you may not be able to wait for the OTA or Sony Companion update to hit your device and you may want to find an alternative way to update it right away.Screenshot_14
