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?
Nah cut here to open is worse. It's always an inch above where you actually need to cut.
