The Moondrop MIAD 01 is one of the most distinctive Android devices of 2024 thus far. It has a 4.4mm headphone jack to go with the more conventional 3.5mm type. Furthermore, it seems it might be as appealing to teardown enthusiasts as well as audiophiles, and may, therefore, also be easier to repair than most modern smartphones.
Like Apple’s magsafe? Not unreasonable, but you’d still need an adapter. I think the biggest issue would be having magnets small enough for the rim of the phone, but still strong enough to keep secure while moving around, but also won’t interfere with other magnetic components like the speakers or compass.
That takes time and effort (i.e. money). Or they could just omit all that stuff and tell people to use the Bluetooth radio they’re going to put in the phone anyway.
