Sony has started rolling out the Android 4.4 update for the Xperia Z Ultra smartphone starting from select regions in Asia. The smartphone with the model number C6833 in Hong Kong is reportedly getting the update first. As of now, this is only available as an OTA, so owners cannot flash the update manually. Users can also try checking the settings to see if an update is available there. Since this is a phased roll out, all Xperia Z Ultra users will not see the update immediately. In the meanwhile, expect the developers over at XDA to come up with a manual update package soon with the OTA now rolling out.
Users of the HTC Butterfly S have also started receiving the update to Android 4.4.2 since Friday. It is a hefty 740MB so make sure you’re on an unlimited connection before downloading the update. Both updates will bring several changes to core functionality, mostly pertaining to stock Android. This is accompanied by standard changes and tweaks to the UIs of the two devices, so a lot will be different after the update.
