Nothing. This issue is there in some dslr cameras also. It's just a limitation. Maybe you can search in youtube, but, still there is no solution as far as I know.
We acknowledge your query and apologize for the same. Please perform the below mentioned steps to resolve the issue:
* Clear camera lens with a microfiber cloth or a cleaning wipe. Gently remove the fingerprint, dirt, and dust from the camera lens.
* Reset camera settings Camera > Settings > Reset settings > Reset.
