Although the LG G-series can be viewed as the company's flagship phone, the LG V-series is more high-end. Besides better specs and hardware, LG's V-series phones tend to have more premium features -- like Google Daydream VR support on the LG V30 or the secondary screen on the LG V20. These premium features are what give LG V phones a leg up on the competition, and put them on an even playing field with Samsung's popular Galaxy S phones.

LG will officially announce the LG G7 on May 2. According to Blass, the LG V35 ThinQ may arrive at the same time as the LG G7, which would mean a May or June release. A late summer or early fall release for the LG V40 ThinQ would mean it could get here in August or September. That would line up well with last year's V30 unveiling, which happened on Aug. 31.
