Majority of the Android-powered devices at this point in time have yet to make the jump over to the Android 4.4.2 KitKat version of the mobile operating system, and it seems that Google is currently testing out version 4.4.3 of Android KitKat, where it comes in the guise of build number KTU72B. This particular bit of information hails from renowned developer LlabTooFeR. Unfortunately, there has been no further information on what kind of new features this particular update will most likely deliver.
However, one of the bug fixes has already been revealed, where LlabTooFeR claims it to be “Probably it will fix known camera bug.” This particular issue could very refer to the issue in Nexus 5 smartphone, where users have observed a rather significant increase in CPU usage whenever the camera application is being used. When that happens, it also places unwarranted stress on the system and also on its battery endurance. Google did promise that they will introduce a fix for the Nexus 5 camera bug in a jiffy, where it allegedly arrives with the next Android update, so this could very well be it.
Apart from that, there are scant little details on the different kinds of enhancements and fixes which supposedly arrives with the Android 4.4.3 KitKat update.
