Issue with my S21 phone camera

[L3xy]

Need help. Every time I open the camera app, the “Security policy prevents use of camera” notification appears on my phone screen and prevents me from using my camera. What's wrong with my camera?

Try this. Go to Settings > Security and privacy > Privacy > Camera access. Check does it set to allow. If not, tap once to allow.
