The mobile world is sometimes a funny one. The coined word "frenemies" seems to be perfect to describe some of the relationships here. Sometimes vicious rivals in public can actually be partners and suppliers in private. Take for example this latest rumor about Apple's 2018 iPhones, which in turn are rumored to finally switch to OLED displays. Those panels are now said to be provided by two Korean manufacturers, namely LG and Samsung, the latter of whom is Apple's sword rival in the smartphone biz.
