Don't know why they don't just make them for their own phones Sony erricsons were my favourite phones lolYou mean their cameras? Yes, Sony makes 42% of CMOS sensor in the globe, not to mention other industrial global shutter sensors.
Actually Nikon, Panasonic (Lumix), Sigma, Leica, Hasselblad, Fujifilm, and many other brands are very dependent on Sony for their sensors. Top end phones, goal tech/eagle eye system in football, olympics, etc. Most of car sensors as well.
