Vernee V2 Pro Camera Review
Specs can be exaggerated as a selling point so if you are expecting the V2 Pro's cameras to perform like it has dual 21MP + 5MP back cameras and 13MP + 5MP front cameras you may be disappointed. Specs on certain sites may say Back camera: 16MP ( SW 21MP ),5.0MP and Front camera: 8MP ( SW 13MP ) + 5.0MP which is honest as long as you know what SW means. SW means software, basically, the phone uses a technique called interpolation using software to add more pixels to images. to be fair camera performance are not solely dependent on pixels. 
During filming the Autofocus keeps refocusing which can be annoying but when taking pictures the effects and filters are nice. No button is designated specifically for the camera. Of course, as stated the Vernee V2 Pro is waterproof making underwater photos and video possible which is a major plus for adventurers.
