Earlier today, we had reported about the issues being faced by users of the new Sony Xperia Z Ultra. A nasty software bug wouldn't allow users to uninstall any apps. And if they tried to do so, they would be greeted by a system UI restart, which is annoying to say the least. However, an OTA update is now available for the phablet which updates the device to the latest Android 4.4.2 KitKat build. KOT49H fixes all known software bugs, so this 444 MB update package is highly recommended for you to get the best out of your device.
