Green dot appears briefly when phone is locked
The green dot appears when I wake up my phone by pressing the side button. In the cc it shows that no app is using the camera . Camera access is turned off for all the apps and it is still happening. Face ID is switched off completely and it still happening. I have iPhone 12 with the latest version of iOS. How it is possible that all camera access has been turned off for all the apps including FaceTime and Face ID yet my iPhone is using camera when phones wakes up?
iPhone 12, iOS 14
