Interesting. I guess it's different strokes for different folks. I'm not a fan of the bump on the naked phone but I also have a Spigen case and actually appreciate the bump.
The Pixel 8 is a little big in my hands so with a secure grip, to me being fingers on one edge pressing the phone into my palm, I can't reach the full screen. It's also uncomfortable to hold it that way for long periods. So often I have the phone with my fingers on the back and my pointer touches the bump, keeping it from sliding, even at steep angles. I don't find the corners harsh but maybe they have worn down somewhat so they are no longer as sharp?
Assisted full self driving is an oxymoron.
