Well, they don't need any know how... It's an Oppo F5 with some changes to make it more powerful (supposed), and rebranded. And probably exactly with the same camera as OP5. We'll see. The problem for them is that S8/S8+ etc. Are cheaper a long the time, so hardly they can justify ask for 500$, they must start to think in cut the price till 440$ - 400$ if want to be competitive. Or cut the specifications... and sell it cheaper.
