Can I recalibrate the camera on my 15 Pro Max?

My camera will not focus in when I try to scan something. It just remains blurry. None of the fixes I stumbled upon fix it. I feel like this should be covered under the manufacturer’s warranty. Is it? I’ve had it for 4-5 weeks but just discovered the defect. I’m so disappointed in Apple for many reasons, but I feel like Apple stole my $1200 that I paid for this phone. DON’T fall for it my fellow Apple loyal friends. You’ll wish you didn’t buy one.
