Modern smartphones have several built-in cameras. It is therefore necessary to select one of the available cameras. Your selection is saved for later, but can be changed at any time.
Don't be surprised: the names shown are the technical names of the device manufacturers. Choose the camera that you feel takes the best photo. Avoid selecting the wide-angle camera: You can recognize these by the fact that straight lines are very strongly curved. These are less suitable for our purposes.
After the trigger is released, it may take a while for the photo to be taken. Just wait a moment and hold the smartphone still steady!
