hey so after I saw your message (cause the same thing just happened to me and my camera is brand new and hasnt taken any fall) i decited to try something. I took it outside when it was supper sunny and turned it on to se what would happen. turns out the camera is smart enough to detect what setting you need. by being outside in the bright sun it turned the setting light on very sunny. then i turned so it had a slight shadow of my body and it switched the light to sunny. then i casted more shadow on it and it turned to cloudy and as u can figure it out when i covered the sensor fully it turned to house. so if you have only noticed this while inside the house, take it out on the sun and see if it changes. then your all good and its a camera feature that suggests which setting u should use lol Hope this helped!
