The realme 12 5G has an IP54 rating for dust and water resistance.  

Here's what that means:

• Dust Resistance (IP5x): It offers protection against dust ingress. While not completely dust-tight, the amount of dust that can enter will not be enough to harm the phone's operation.
• Water Resistance (IPx4): It is protected against splashing water from any direction. This means it should be able to handle light rain or accidental splashes without issues.

Important Considerations:

• Not Waterproof: An IP54 rating does not mean the phone is waterproof. It is not designed to be submerged in water or withstand prolonged exposure to significant amounts of water.
• Accidental Damage: The warranty typically does not cover liquid damage, so it's still important to be cautious around water.
• Realme's Advice: Realme advises users to never charge the phone when it is wet and states that liquid damage is not covered under warranty.  
• "Rainwater Smart Touch": Some sources mention a "Rainwater Smart Touch" feature, suggesting the display is designed to be more responsive even with water droplets on it. This is a feature that enhances usability in wet conditions but doesn't change the underlying IP54 water resistance rating.  

In summary, the realme 12 5G offers a degree of protection against dust and splashes of water thanks to its IP54 rating, providing some peace of mind for everyday use. However, it should not be intentionally exposed to significant amounts of water or submerged
