Yi 4K+ action camera review: Powerful, and so simple to use
(Android Central)

Yi Technology makes some great action cameras with decent mobile connectivity. And this is the best of them all. As smartphone cameras continue to improve, for many the need to carry a dedicated camera continues to disappear. But there are times you want something that isn`t your phone. Action cameras aren`t what you take out with you to take high-quality landscape photos, or to cover a wedding. But they`re really good if you`re into mountain biking, or skydiving, or any number of other outdoorsy type activities. You wouldn`t (probably) strap your Pixel 2 to your helmet, but you certainly would an action camera. I`ve spent a bit of time playing around with the Yi 4K+, the company`s most expensive, well-equipped action camera. And it`s really good.
