OnePlus Ultra HD (4K) TV

OnePlus is a Shenzhen-based start-up and producer of smartphones founded in December, 2013. The company's claim to fame is its bid to offer flagship-level specs in its smartphones, at affordable prices. OnePlus initially sold its smartphones only through an invite system where customers would be sent an invite to purchase smartphones and they had to make the purchase within a fixed time frame. Of late the company has held open sales of its smartphones too.
