Can I ask what phone did you buy? Only if you confortable to share it ofc. I am looking for a new one. I loved my Samsung Note9. Everything was great, it had stylus, jack, battery life, oled screen, decent cameras. The only thing missing is andoid OS update support. It still better than most middle range phones...

The point isn’t whether it’s needed or not. It’s not about space or features. The point is that a major player made a design decision and bucked the system. And while there may still be some phones with audio jacks, the majority of mainstream phones don’t. That major player is still successful, and other companies followed suit.

Can we agree this is what should happen to HDMI. No?

tbh I looked at audio jacks in internals, and they do usually have double the footprint on a pcb than what you see outside of it, at least on low end consumer devices:

That's not to say that they couldn't put anything more compact in a highend device like a smart phone.
