Current Nexus devices will not get Android N seamless updates
Slowly, but surely, Microsoft Windows and Google Android are getting closer and closer. For example, Android N will offer seamless updates, downloading and installing them silently in the background, similar to the well-known Windows Update.
Unfortunately, none of the Nexus devices currently available will get support for Android N seamless updates. Even more, the Pixel C will not be supported, either. Android Police writes that "it was confirmed to us that these have no bearing on existing devices getting seamless updates."
This update method uses two partitions, each lives on the device at any one time. While one is in use by the OS at any time, the other can be used to download and install the update. Obviously, the operation takes place in the background, without having to bother the user.
Since Android N should come out pretty soon, we will keep an eye on this matter and get back to it as soon as anything new surfaces.
