HTC is currently rolling out the much-anticipated Android 4.4.2 KitKat over-the-air (OTA) update to all unlocked models of its flagship phablet, the One Max, in Europe. In terms of functionality, the upgrade brings Android 4.4.2 KitKat and Sense 5.5 to the device, complete with the usual plethora of bug fixes, speed optimizations and stability improvements that we’ve grown to expect from any major software update.

Android 4.4.2 is a considerable upgrade from 4.3, packing a completely redesigned user interface, SMS message integration in the standard Hangouts application, Google Now on the home screen, Wi-Fi printing capabilities for HP ePrinters and Google Print customers, autocomplete for the traditional telephone dialer, Emoji integration for Google Keyboard, built-in word processing software and lots more.

The full changelog for the rather hefty 300MB update can be seen below:

• Android 4.4.2 OS upgrade.
• Improved system performance.
• Increased transfer speeds via MTP.
• Hangouts has been named as the new default messaging application.
• Transparent notification bar.
• Improved RAM management.

If you’re in a European country and own an unlocked variant of the HTC One Max, and haven’t yet received the OTA update, you can head into “Settings,” then “About Device,” and select “Check for Updates” to manually scan for the upgrade.
