@ChocoHunter69 Does this occur all the time and directly after rebooting the device? If a simple reboot does not solve your issue, try booting in safe mode and see if it persists. That way, we'll know if you have a third-party application messing with the camera.
Hold the power button -> Long-press "Power off" until it asks you to reboot to safe mode
