How do I set iPhone Camera app settings for better looking photos?

This screenshot of a part of the video that I just shot was set 4k 60 fps and at only 5x and there is no enlargement of this screenshot whatsoever. Please help me. I have erased all content and reset all settings a gazillian times and I even made about 3 different Apple accounts (or IDs) during the setup process of the iPhone 16 pro max. Any positive advice and comments is much appreciated. But, actually I also see images like they were taken from an adult magazine. They are very vivid and they disappear as I look at them. I believe that I have a virus snd or spyware and or malware that was put on my phone when my roommate borrowed my phone. Because I heard someone on the phone’s spyware telling him how to do something. Like she said “he won’t be able to get it off the phone”. When he gave me back my phone a still voice or my silent thoughts told me that he did something to my phone. He doesn’t like me. And when I was about to go to the iPhone repair shop he was like “where you going Bob! Why you going there! I don’t see anything there’s nothing there!” He’s a boldface liar as those images were very clear as seen in my phone and not sent to a pc or Mac for viewing. He’s a bully! Why would he care or be concerned about where I’m going or doing. For it’s none of his business! H just didn’t want to be found out for installing those infections onto my phone!

They are extremely clear.

It is impossible to make the added images anymore clearer as they were added after the video was taken.

Thanks so very much

I’m very sorry

How to have a great antivirus and an anti spyware/anti malware app?

inside of the circles are images that aren’t really there. It’s ok if you don’t see them. Never mind it’s ok. Take Care. Have a great rest of your day.

Thanks so very much for your suggestion or advice!!!!
