Why can’t I take pictures on iPhone 6? There is no video function, why?

The reason is that some APPs conflict with IPHONE.

Go to Settings->Privacy->Camera->Disable the conflicting application; ? Or delete the conflicting application. ?

When you turn on the camera again, the lost "video/slow motion" function is back.

The iPhone 6 camera has 8 million pixels (f2.2, 1.5μm pixels) + front-facing 1.2 million pixel camera.

The iPhone 6 does not have sapphire glass or a higher-pixel camera. It only has a 4.7-inch and more powerful A8 quad-core processor to drive a more powerful experience. Whether the new generation of iPhone6 ??meets the upgrade expectations or continues to be a regret, as long as it is incomplete, the product will continue to become better; just like Apple's logo, if it is missing a corner, it will be outstanding.
