12 pro waterproof

No iPhone is waterproof.

They are water resistant.

Apple’s official advice:

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

To prevent liquid damage, avoid these:

• Swimming or bathing with your iPhone
• Exposing your iPhone to pressurized water or high velocity water, such as when showering, water skiing, wake boarding, surfing, jet skiing, and so on
• Using your iPhone in a sauna or steam room
• Intentionally submerging your iPhone in water
• Operating your iPhone outside the suggested temperature ranges or in extremely humid conditions
• Dropping your iPhone or subjecting it to other impacts
• Disassembling your iPhone, including removing screws

Buy a device designed for underwater photography. Some cellphones are supposedly designed to high-grade military specs (Caterpillar, the construction equipment company, has their name on a line of these).

If a company does not declare "water proof, guaranteed", is a bad bet in my books. Apple does not guarantee "waterproof".

Even GoPro cameras (biking in the desert, riding on trucks in the desert or for motorcycles on the freeway, at night in the woods, etc) either specifies that a model is waterproof, or provides a plastic case for the cameras that is itself waterproof for underwater activities.

If you want to destroy your iPhone...........please do....

No iPhone is waterproof; never has been.

Nowhere does Apple state any device they make are waterproof.

They clearly state they are water resistant.

I mis-stated with "bad bet". I simply meant that if you intend to use underwater, look to those who guarantee waterproof. My iPhone SE works just fine when used as intended.
