IDC reports that Samsung sold 72.4 million smartphones in the second quarter of 2014. The pace of growth is slowing as Samsung faces intense competition from Lenovo, HTC, ZTE in the low end of the smartphone market. High marketing costs are pressuring margins. Samsung second quarter net profit increased by 50% over the prior year quarter. Samsung expects weaker sales of the Galaxy S4 and has ramped up marketing promotion. Demand for expensive smartphones is declining. This has resulted in a 12% decline in Samsung's share price since late April when Samsung started selling the Galaxy S4. Apple faces a 22% decline in profits in the second quarter of 2013.
