Have they always been there or just appeared ? @Members_INRAoVC
Try running the diagnostic tool test in your Samsung Members app.
Then try > Safe Mode > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict.
Try clearing the camera cache via Settings > Apps > Camera > Storage > Clear Cache, but if that doesnot help and all looks OK including your camera lens module then a Samsung Service Centre can assess your phone.
If I can be of any further help then please don't hesitate. Take care. 😎

The advice I offer is my own and does not represent Samsung’s position.
