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.
I've had my 50 inch LG Plasma TV for about 3 to 4 years now, and over the last year or so, it started developing very thin vertical lines. There are now about 10 lines going down the screen and they are driving me crazy. They show up best on a red background, but they are still visible on almost any colour.
