Thank you for working on this! I want to be honest, though, and say I think you're missing what the
majority of users on this forum want in a small phone.

No, bad. What most of us want are the particular set of trade-offs made by phones around 2015. Design wise, that means that you've got to have another hole in the bezel, because there's going to be an earphone jack. That's apparently anathema for modern phones, but probably 90+% of us want it. Again, that's Hacker News specific. I haven't polled the market in general. I just know that I (and many others) won't consider buying your phone unless it has a jack.
Likewise, I have not much interest in a phone with a hole punched in the screen (?!) for a camera or an ugly "notch". I realize this is more controversial, but I don't know the last time I even used a front camera. I think it's more in keeping with the ideal 2015 design to make the bezel just large enough to contain a camera, speakers, light sensor, flash/LED, etc. I would reluctantly buy a phone with a camera hole if it was otherwise acceptable and there was no ideal option on the market.
I'd prefer if the back were completely flat as well, with no camera bump. That's totally just my aesthetic preference though, I don't know how others feel. I think it should be possible to achieve this if we're going back to not worshiping thinness, and making the small phone thicker for the sake of battery life.
I'd also prefer a 16x9 display to whatever Apple is doing now. So much web video is still 16x9.
