Samsung operating profit from the mobile business recorded its steepest rate of decline since the first quarter of 2017, as cheaper Chinese-made handsets put pressure on margins.

Higher marketing expenses and the disappointing performance of the flagship S9 smartphone, which fell short of its sales target, weighed on its mobile performance

The mobile business booked a 34 percent fall in operating profit to 2.7 trillion won ($2.4 billion) in the second quarter, its biggest decline since the Galaxy S7 was Samsung’s flagship model early last year.

Same thing will happen with cameras (present Sony margins are much more than even Apple ones!), just need fresh though and competition.
