I'm still want a phone with expandable storage and a headphone jack. Sony had one, but I don't know if they're selling them and I've heard they have their own issues too.

Honest question here - is there a situation where you need to be able to use the headphone jack and USB-C at the same time?

Because there are very cheap, lightweight adaptors to headphone jack from USB-C.

One extra 'thing' to need - at the moment I know that I can play music through anything that has a line-in, with just a cable. However Bluetooth seems to work ok - for devices that support it.

Not OP but my concern is putting strain on the charging port by walking with headphones while my phone is in my pocket.

Wireless chargers are pretty good but it’s still a pain to wear out your port.

There are some 90-degree adapters that would probably minimise that.

I can dual-SIM my iphone by using one e-Sim and one physical. The only thing it is not, is small...
