The company announced the Galaxy Note 4, which comes with a 5.7-inch organic light-emitting diode screen with improved sensitivity to stylus input. The handset also has a camera with enhanced functions, including image stabilization. The South Korean electronics giant showed off another new product, the Galaxy Note Edge, featuring a screen that extends all the way to the curved edge of the handset. The latest Galaxies debuted in Berlin, where the IFA trade show took place from Sept. 5 to 10, as well as in New York and Beijing. The unveiling of flagship products in China was a first for Samsung, which is sharpening its focus on the country. China is the world’s largest smartphone market, accounting for a third of global shipment volume. Samsung faces fierce competition from local players such as Huawei Technologies and Xiaomi, which are significantly expanding their shares. Samsung Electronics’ profit has been shrinking. For the April-June period, its operating profit dropped 25% on the year to 7.2 trillion won ($7.02 billion), a third straight quarterly decline, mainly due to sluggish smartphone sales. For the quarter, Samsung’s global share of the smartphone market, in terms of shipment volume, was still tops at 24.9%, despite being down 7.4 points on the year, according to U.S. research firm IDC. Rival Apple is gearing up to roll out its newest iPhone with a large display — Samsung’s strength — as early as this month. Samsung may be faced with retooling its strategy if the new offerings fail to put the business back on the path to growth.
