what are some problems faced by people with iphone 16 pro

i will go from iphone x to 16 soon and was deciding to get the 16 pro but many people were saying that the camera was of bad quality and gets stuck. my cousin has the 15 pro max and he faced no issues with it and since i had to get a new phone i thought of buying the 16 or 16 pro ofc the 16 pro is better but i want a good camera and performance. and will apple fix those issues?
