The LG G5 has a replaceable battery that pops off the bottom of the phone and pulls out. The G5 also halts the trend toward larger flagship phones. It runs Android 6.0 (Marshmallow), but with some changes that are sure to be controversial. LG has done some work with the camera, too, with two lenses: a 16-megapixel camera with a 75-degree range and a wide-angle 8- megapixel camera. The Galaxy S7 and Galaxy Edge are the latest phones to be unveiled at Mobile World Congress.”]
