Samsung
Although not technically “partners,” the relationship between Apple and Samsung is certainly an interesting one. As smartphone makers, Apple and Samsung are bitter rivals who are always trying to outdo each other. But their relationship gets a bit trickier than that.
Samsung is Apple’s largest supplier of OLED displays panels for its iPhones. And the Cupertino tech giant is actually Samsung’s biggest external customer. While Apple is trying to tap other display makers to compete with Samsung, it’s probable that the two companies rely on each other a lot more than you might expect.
