The Factionless, the ones who don't fit in anywhere. Factionless is a status in which a person is not welcome into any faction. This is described as being homeless and even worse than death itself because the factionless have to suffer. It is a common practice for Abnegation to give food and medical attention to the factionless.
The LG G Flex isn't just a curved screen, though. It's a complete, finished product and must be judged as a smartphone in its entirety. The screen, in addition to being curved, is huge: a 6-inch OLED display with 1,280 x 720 resolution.
In 2017 we're starting to see the emergence of QHD+ phone displays. These are longer than typical mobile screens, giving a widescreen appearance which is better suited to movies. The exact resolution of a QHD+ screen will depend on its aspect ratio, but you can expect supremely crisp visuals no matter what. For instance, the LG G6 enjoys an 18:9 aspect ratio (or 2:1 to put it more simply), and a screen resolution of 2880x1440.
