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.
The LG G3 is also running Android 4.4.2. It has a thickness of 0.35 inches with similar dimensions to the Vista. It weighs a bit less at 149 grams. The display size is 5.5 inches and the resolution is 1440 x 2560 pixels which is way more than the Vista.
