The iPhone 6 & 6 Plus are the best-selling smartphones of all-time at 220M combined.
No matter if you believe Note series is the real Samsung flagship, they don't sell as well as their S line or iPhone. Last year, Note7 was only expected to sell 20M-25M. An iPhone 3Gs has outsold every Note model.
Other brands would die happy if their flagship could sell as well as a S8 at 20M. They would be lucky to hit 10M-15M. Most of Samsung's market share with mobile is with their midrangers similar to Nokia in the previous decade of dominance.
Samsung's market share peaked in 2013 until the Chinese undercut them in prices by 2014 with phones like the OnePlus One and flash sales from Xiaomi.
China's market is very volatile like runners passing on a baton. In 2013, it was Lenovo. In 2014, it was Xiaomi. In 2015, it was Huawei. Recently, it is OPPO. Most Chinese's taste with brands is like their food. They want it cheap, fast, and good!
The truest and best variants of Samsung flagships are made in South Korea. Exynos and Samsung camera sensor over Sony's. That's the truest Samsung where nearly everything is built in-house.
The iPhone X is assembled in China thanks to Foxconn. A patchwork of Asian-manufactured components from Samsung, Sony, and TSMC.
Whatever you do, Samsung's DNA is everywhere. I realized it as early as original Xbox when the Samsung disc trays were superior to the Phillips ones. My LG G3 S' internal storage is made by Samsung. My iPhone SE has the Samsung A9 chip.
Anytime you pick up an iPod, you thank the South Koreans for inventing the mp3 player. Samsung-made components were found in the very first iPhone. Anytime you admire the X's display and pick which storage capacity, remember they are made by Samsung.
Fun fact: GRiDPad was the first commercially available tablet released in 1989. Guess who manufactured it? Samsung.
Anytime you pick up your iPad Pro with Apple Pencil, just remember Samsung manufactured the very first tablet with stylus.
Samsung's DNA is everywhere even if you can't see it. From fish market started in 1938 (older than Sony) to market leader in multiple industries as of today.
It's not about debating. It's about educating.
Geonbae!
