The latest model introduces a slightly smaller curved AMOLED touchscreen than on last year's Axon 20 Ultra, but its faster refresh rate, larger battery, and upgraded cameras aim to outweigh the smaller size.

I know that many other companies also use 20:9 aspect ratio, but seeing this photo highlights how rediculously tall and wasted screen space there is. Most content would be limited to the width. The only usefulness is when typing in portrait. I wish they would shorten the aspect ratio with the same display to body ratio so that the phones could comfortably fit in your pockets again.
