I took the below photo at daylight at a building roof. There are many strange artifacts that is not hardware fault as it also took good picture in a series. The computation often does this with moving objects too. Like double hands or legs.
Photo res. is 4:3. AI stuff is on. Auto nightmode detect is on. What else do you need? I have set the power button to start camera on double press. I pull phone from my pocket. Double press power to start camera. Press shutter.
