@nico1345 Are all apps up to date including Camera and particularly One UI Home . Have you checked your permissions to see all is ok there, Apps-Camera-Permissions. When clearing cache an idea to Force stop via Apps-Camera and then clear cache via storage-Clear Data and cache.
could also try in Safe Mode: https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
If camera works there would pinpoint issue with recent third party apps.
If no resolution advisable to wipe the cache partition to clear temporary files, the cache can contain unnecesary or corrupted files and the temporary files are deleted but Data is intact.
1. Turn off the device.
2. Connect To Computer or plug in USB-C Headphones , Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release all three keys.
4. An 'Installing system update' message will show for 30 - 60 seconds before the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.
can also repair apps via the same Recovery Menu.
If there are still issues check the Diagnostics to see if any errors are identified. Go to Samsung Members-Support-Diagnostics-Camera. You may need to send Error Report: Samsung Members-Support-Error Report.
I would suggest trying additional troubleshooting before seeking inspection.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
