Since the camera app already uses a black background, why should this feature be added? If you're in a dark room or outside at night and need to go into Google Camera app settings, you'll be immediately blinded by the white background of this page. Why does Google enable dark mode when the battery saver is turned on? If you have a phone with an AMOLED screen, a black background means fewer pixels need to be activated, which means that the phone uses less battery power.
Another change can be seen when switching between camera, video and portrait and panorama settings in the app. For example, if a user has switched between camera and video, they would first see a black transitional screen with the icon of the selected center setting. If you switch between settings with version 6.2, the screen will not turn black and instead display what your camera is watching. There is also a zoom effect while the icon of the selected setting remains in the center of the screen. And there is one last change. When the selfie flash front-facing flash is turned on, the flash icon appears on the display.
Remember that you need version 6.2 of the Google Camera app and a Pixel handset to enjoy all these new extras
