An often overlooked and unrealized line of devices are the LG brand smartphones. Specifically the G4/G5 and the V10 smartphones are the best I've ever used. They have an incredible camera and great multitasking and multiwindow operation. Though the battery in the G and V series may not last as long as it's competition, The Samsung Note and S series, the customization, personalization, and operation are well worth the shorter battery life.
