Huawei is making some really impressive technology, but I don't trust them at all. Of course it's this age of not being able to trust any companies, but I trust Huawei the least... even though some of their tech and the low prices look amazing.
What I want to know is how come Huawei can stuff so much advance photography hardware in the phone and Samsung can't. I am not talking about risky stuff like fast charging that Samsung doesn't want to take a chance to implement. The low light and optical zoom are so much better than Samsung and Pixel even to regular joes.
Most likely that they have a very tight, efficient supply chain and that they're willing to take a loss or go with incredibly slim margins. Being one of the biggest companies in China tightly connected to the Chinese government and being (probably?) the preferred tech leader in China at the moment gives them negotiating power that even huge companies like Samsung or Apple (both outside of China) can't command.
But, mostly, I think they're willing to take very, very slim (or negative) margins to break further into global markets.
They're also probably more willing to take chances on new technology that the seasoned companies, Samsung, Apple, Google, etc., really can't take. That was the case with OPPO a few years ago.
