This preview shows that mobile phones have developed way beyond the peer-to-peer communication devices which they once were. The emphasis seems now to be on augmented reality and AI neural networks. These are both compute-intensive applications where the higher powered models will benefit most. This beside improvements in communication and security of course.
Nice that they used a rotary phone dial with an eleventh mark for this Android version 11. I am sure 95% of the new Android 11 users won't recognize it as a phone dial :)
