Not true. A break would mean short term losses for Samsung until it's devices fill the void left by Apple. Apple on the other hand will need to find a new fabrication partner and would set back the release of any new devices by 3 to 4 years. However I am sure there are ironclad contracts between the 2 to ensure that Samsung cannot do this. Why else would Apple be so arrogant.
Well you are right and wrong
a) Yes Apple and Samsung have long term contracts that Samsung couldn't escape. They also wouldnt want to. What Apple does is pay well in advance to lock in the components at a good price. When there was a component shortage (think it was memory or screens) Samsung had to supply Apple before their own telephone arm
To give you an idea Apples often spends more than a Billions in advance to lock in components well in advance
These contracts are very profitable for Samsung. They would not want to lose this contract
b) So Apple always have a long lead time to negotiate these things. They couild switch component suppliers but they probably wouldnt want to because change equals risk
Havig said that if Samsung jacked up priices they would move
c) So Samsung wouldnt really fill any hole because Apple would get their components.
Samsung would lose their component profits.
It would mess Apple around though. Transition costs money and effort
BUT they both need eachother.
And behind the scenes the Execs can separate the battles.
Component Division no issue. Phone Division hassles
