Do you have an iPhone 13 Pro?So some users aren’t caught by surprise when the cameras on the iPhone 13 Pros do what they are designed to do.
My 13 Pro Max changes to the Ultrawide camera when an object get about 2 ft to my phone. Which is a huge PITA as the Ulrawide camera isn't anywhere near as good as the Wide camera. I'd have thought that the ultra wide would kick in when an object is around 10cm from the camera.
