As i said before, they started well with the marketing but they lost themselves when they started production. I think that the production cost with all of those features was too high for them and they cut some or it was just a marketing mistake.
Anyway, it's not the money, it's the principle that counts.
If you recieve a answer from them please share it with us.
OK, so I asked them about the key specifications and expected an honest answer. Here is their answer: "Hi, the functions of voice control and GPS are not available so far, but our engineers are working on them, will update these functions to the future firmware. Yes, we confirm the S300 action camera built with Sony IMX377, Hi3559v100 chip and 8G all-glass lens. Thank you."
I'm from the States, so I am not sure exactly how products are made, advertised and sold oversea. But my thought is they are not used to being completely consistent throughout their design, engineering and marketing process. Marketing department did not work closely with other departments prior to S300 being released. They rushed out a product that wasn't ready with all initial features.
