LG doesn't generate the same amount of fanfare as Samsung, Apple, or even Google, but it's mostly down to lack of marketing and poor global availability, not poor products. Hardware wise, LG has been pioneering and producing great phones with great specs and components for years. They were among the first to have a wide-angle camera, they got the boll rolling with curved displays, and to this day they still have some of the best audio in the smartphone industry. But, their software is what usually turns people away. A poorly made Android skin and close to non-existent software updates have hurt the brand tremendously, despite the so called "Software Upgrade Centre" that was launched last year.
As for the dual screen, it's definitely a different approach from what the likes of Samsung and Huawei are doing with their folding screens, but it just doesn't look as elegant as what Microsoft showed off a few weeks ago. But I'm not about to criticise LG for doing something different. In a world where Apple and Google only prefer to imitate the competition rather than innovate, it's down to the likes of LG, Samsung, Huawei, Xiaomi, and even Microsoft to deliver the out-of-the-box smartphone concepts of the future.
