this morning I received the android 4.4 update for my moto g. however, some features of kitkat aren't present. for example, I can't say "okay Google" to activate the voice search and if I touch and hold on my home screen the widget option doesn't appear. the home screen still looks like android 4.3 as well. is this really the 4.4 update for moto g?
The only other changes are behind the scenes making the OS run more efficiently and they have introduce ART which is Android Run Time which they will eventually be switching for the dalvik environment they have been running since the first appearance of Android. It will slightly increase battery life but really so slight right now its not anything amazing battery saving wise. What it will do greatly is reduce the amount of force close / crashes of apps while running them. So if you notice that your phone has apps crashing fairly frequent give ART a try it has really made a difference for me as apps very rarely crash while using ART which was not the case running dalvik. ART can be enabled in the developer settings of the device. When turned on it will take a bit as it optimizes your installed apps and restarts the device and will do the same when turning it back to dalvik.
