Still I could see two of my camera is working smoothly. All functions are also okay. Just two of my back camera is not working..

If this phone is not waterproof, then why maximum web result says that it can be stay 30minutes in underwater :/

iPhones are water-resistant, not waterproof. They're designed to remain functional when splashed, not when submerged, though in some cases they can survive such an immersion.. See:

About splash, water, and dust resistance of iPhone 7 and later - Apple Support

In addition, wear and tear over time can degrade even that resistance. And putting it in rice to dry it out, if that's what you mean, is likely to cause even more damage (using rice to dry any electronic device is one of those misguided myths that should never be followed).

The bottom line is that water damage is not covered by warranty. You will almost certainly need to pay for any needed repair.

You are confusing a controlled laboratory test with real world conditions. They are not the same.

Apple will not repair a water damaged phone, so you are going to need a new phone.

It's only a matter of time before your phone fails completely. You should make sure you have backed up your device ASAP. It sometimes takes days for corrosion to do it's damage. If this was saltwater, I'd be most concerned of the battery catching fire at some point.

An iPhone is not waterproof. Your phone has been damaged by being under water. You need a new phone.

iPhones are sadly not waterproof, you can try to take it to an iPhone YouTuber but he is in turkey and I do not know the location. If you do go and visit him, next time use a fat case that holds a phone then I will be waterproof underwater. If you don’t visit him go to Verizon and trade it in. They are accepting trade ins in any condition

some iOS phones might be, most… not

iPhones are not submarines.
