Question: what is the difference between a iphone 6 and 7?
Answer: While the iPhone 6 has a 1.2-megapixel FaceTime camera, the iPhone 7 has a 7-megapixel sensor with auto image stabilisation for superior selfies. It also supports the clever flash feature introduced on the iPhone 6S, which uses the screen as a flash when taking selfies, but it's now 50% brighter.
