Google outlined a little more about Android N at its IO conference, including its seamless updates capabilities.
This allows your device to install updates in the background without shutting down the phone entirely. However, it’s unlikely that this feature will work on current handsets.
While it’s technically possible, according to Google who spoke with Android Police, it would require repartitioning the entire phone. This isn’t easy to do and those who try it run the risk of breaking their phone or losing data, so it’s unlikely that it’ll be something that Google supports.
The first Android N devices, likely to be the new Nexus devices, will be released later this year. Picking up one of these handsets seems to be the best way to avoid that inconvenient “Android is updating” screen.
