Across the world, the biggest smartphone manufacturers are Apple (28%), Samsung (24%), Xiaomi (12%), Oppo (6%) and Vivo (5%). However, there are geographic patterns in popularity, with Apple dominating North America and East Asia, while Samsung leads in South America, Europe, Africa and West Asia in addition to its home turf of South Korea. Xiaomi is the most popular phone brand across South Asia, Spain, Venezuela, Ukraine, Madagascar, Kyrgyzstan and Palestine, while Tecno is popular in West and Central Africa. Oppo, Vivo and Huawei lead in Indonesia, Bhutan and Togo respectively.
Wait. Apple can’t be ruling in, East Asian countries. Personal experience. (Should not be in China as well.)
Look at the bar chart below. Apple has almost a two-third marketshare in Japan, but only about 20% in China. But China has a variety of Android manufacturers, so that Apple is the single biggest vendor.
