Sony is probably the next one on the chopping block.
To be honest I don’t know why - quite literally, not being snarky - they don’t release a Sony Alpha Xperia APS-C sensor phone. Sony’s market is for cameras; nobody cares otherwise.
Man, pour one out for the LG VX-8300, best cell phone ever made.
If you want an APSC phone that can actually focus, the lens will need to be at least 20mm thick.
For that large a sensor you also need a considerable amount of space between the lens and the sensor. The thickness of the A6000 series body is indicative of what you need.
