As a standalone flagship phone, LG’s new G8X ThinQ doesn’t stand out -- it’s perfectly adequate. Attach its Dual Screen case, though, and things suddenly get more interesting. Combined, these devices offer a taste of the multi-screen life other companies have attempted to popularize, and they’re surprisingly good for multitasking. After all, the G8X and its second screen often act like two entirely separate phones. Where LG falls short is polish: Some experiences that use both screens can be finicky or feel limited. If you can find a good deal on a G8X and its second screen, it’s definitely worth consideration.
