Oops. LG is supposed to be unveiling its range-topping G4 smartphone on April 28th, but well-known leaker Evan Blass has discovered an unannounced product site that reveals a ton about the new Android flagship a couple of weeks in advance. A lot of the text is clearly placeholder material, but there are a few noteworthy revelations here. The G4's back will have several color options (including multiple shades of real leather), and that super-fast f/1.8 camera is helped out by an infrared color accuracy sensor, second-generation image stabilization and a full manual mode.
