LG's V20 flagship phone promises superb hi-fi sound

In the world of smartphones, a "flagship" phone usually designates a company's best, most fully featured product. LG, however, challenges this definition: With its semi-modular design, the company's G5 was a different kind of flagship, and last year's V10, with its dual screen, was also an experiment of sorts.  Now, LG has begun to share details about its upcoming LG V20, scheduled for a Sept. 6 launch.  SEE ALSO: LG will announce first Android 7.0 Nougat phone on Sept. 6 Besides being
