Hello txangyl.86,
Welcome to Apple Support Communities!
We want to help with your iPhone camera concerns regarding the condensation.
We see you viewed the Apple Support page for About splash, water, and dust resistance of iPhone 7 and later - Apple Support
You should let the iPhone fully dry to see if that resolves the issue.
From the link: "If your iPhone has been exposed to liquid, unplug all cables and do not charge your device until it’s completely dry. Using accessories or charging when wet might damage your iPhone. Allow at least 5 hours before charging with a Lightning cable or connecting a Lightning accessory.
For wireless charging, wipe off your iPhone with a soft, lint-free cloth—for example, a lens cloth. Make sure that your iPhone is dry before you place it on a compatible wireless charging mat."
If the issue continues, please reach out to an Apple Support Advisor for further assistance as it could be hardware related: Apple Support
For the best steps to clean your iPhone, see here:
"iPhone 14, iPhone 13, iPhone 12, and iPhone 11 models
These models feature glass with advanced textured matte finishes either on the back glass or around the camera area. With normal use, the textured glass on your iPhone might show signs of material transfer from objects that come in contact with your iPhone, such as denim or items in your pocket. Material transfer might resemble a scratch, but can be removed in most cases.
Clean your iPhone immediately if it comes in contact with anything that might cause stains or other damage — for example, dirt or sand, ink, makeup, soap, detergent, acids or acidic foods, or lotions. Follow these guidelines for cleaning:
Your iPhone has a fingerprint-resistant oleophobic — oil repellent — coating. Cleaning products and abrasive materials will diminish the coating and might scratch your iPhone."

We hope this helps to resolve the issue with the camera or get Apple Support involved directly to reach a resolution.
Cheers!
