My Galaxy S23 is not giving clear and focused videos, any reasons?

Few days back, I purchased S23 from Flipkart. I only bought it coz of its camera and Snapdragon Gen2, all checks were right. however I am not getting good and focused videos on the selfie camera. I compared it with my dad's S21FE and FE was clearly better, even some of the photos from the back camera of S21FE were better than S23. I've already went through all the camera settings. Has anyone faced similar issues or Is there something else I can do?
I feel so bad coz this is my first flagship mobile and bought it with my savings
