Description
Android boot time could be dramatically improved by leveraging checkpoints/snapshots approaches (might be sufficient for variety of products/use cases), on the other side it would be great to study deeper if Android cold boot speed could be improved, at least for automotive/IVI scenarios (get display/video/audio enabled early)
