How to turn a mobile phone into a camera

If Samsung mobile phone needs to record video, please operate:

Turn on the camera that comes with the phone-click the camera icon on the right-the phone will be prompted to turn on the camera-and a red dot will appear on the screen. (Operation mode of some mobile phones: After turning on the camera-slide the camera icon to the camera icon next to it)

Tips: If you need to use the front camera to record video, please switch the shooting mode to the front camera first. Mode: Turn on the mobile phone camera, find a small camera icon with left and right arrows, and click the icon to switch.
