Nexus owners used to have reasons to be proud because they are expected to receive Android updates first. The point of getting a Nexus is to be the first in line for such updates from Google— or at least that’s what we counted on. Now, though, Google is warning that although it has its own targets for firmware updates, the carriers may not play ball.
Supported Nexus devices usually would get important updates within two weeks from Google, but exactly when it will actually reach your device will be be “based on your carrier” the company says.
This is a common problem with Android. Even if a software update is already announced by Google, there is no guarantee you’d get it on your device right away because it’s either you have to wait for the phone manufacturer or the network carrier to officially release it.
Bad news for Nexus owners? Potentially, though it remains to be seen how pro-active carriers are, and what sort of delays they end up introducing. While anyone can get the update without having to wait for the official, over-the-air variety, that's only if they know how to install the software update themselves, not to mention where to get it.
Update: An earlier version of this article suggested all updates would be carrier-controlled and thus delayed. We apologize for any confusion caused.
