Note 20 Ultra front camera deteorating

[Prashh]

It's been around 18 months with my Note 20 Ultra, over a period of time and updates I feel the front camera clarity or the quality of pics have deteorated. I don't find the pics now to be sharp or crisp enough. Pictures looks Pixelated or of low quality when compared. I took the phone and compared it with other Note 20 Ultra in the showroom and find those phones clarity to be much better when compared. 

Any suggestions or ideas to fine tune it.

P.S. I have tried all the YouTube videos and settings possible.

Ok sure let me give a try

True. But same phones with same processor and same updates and functions should function equally but don't know what's the issue.

Did you checked with service center ?

No since it's out of warranty now they will say we will have to replace it with a new one etc
