Here's how China's Huawei, Oppo are challenging Apple, Samsung's dominance

Apple and Samsung’s domination of the smartphone world is being challenged like never before, with Chinese companies muscling in with cheaper and just as innovative devices.
In an ominous sign for the tech titans - whose iPhone and Galaxy handsets have had a stranglehold on the almost $500 billion market for years -- China’s Huawei Technologies Co. has unseated Apple to become the world’s second-largest smartphone maker. Now, it’s setting its sights on No. 1 Samsung, which has seen disappointing profits as Chinese phones gain share of a market that looks increasingly like it has peaked.

And others are not far behind. Here are the players -- and phones -- to watch:

Huawei: The Big Threat

Based in the southern Chinese tech hub of Shenzhen, Huawei is ploughing cash into bolstering its phones’ camera capabilities in a quest to dominate. Its flagship P20 Pro boasts a three-lens camera that was co-engineered with the 104-year-old German camera maker Leica. Huawei also offers a shiny, rainbow-effect handset finish known as Twilight, differentiating their product from the many monotone smartphones on the market.
