Google confirms that the Galaxy Nexus will not get Android 4.4
Android 4.4 KitKat may be bringing better support for low-end and older devices, but that doesn't mean that Google is bringing the update to all of its Nexus devices. When Google announced the availability of Android 4.4, we noted that the Galaxy Nexus was not on the list of devices. Now, Google has confirmed that it will not be pushing the update to its two-year old device.
Interestingly, Google is citing the 18-month update policy as the reason why the Galaxy Nexus won't be getting the update. Google's support page says, "Galaxy Nexus, which first launched two years ago, falls outside of the 18-month update window when Google and others traditionally update devices." This makes sense, but it is also annoying given that Android 4.4 is supposed to make older phones run better.
The 18-month update policy has made a bit of difference in the ecosystem, but of course manufacturers and carriers will exploit the loophole in the policy, which is that there is no real timetable as to when the update has to come, just that it has to. Either way, if you have a Galaxy Nexus, you may want to look into grabbing a Nexus 5, before they're all gone.
