What steps should be taken immediately after an iPhone is submerged in water

1. Turn off the iPhone immediately: The first and most important step is to turn off the iPhone as soon as possible after it has been exposed to water. This helps prevent short circuits and further damage to the internal components.

2. Disconnect from power source: If the iPhone was charging when it got wet, immediately disconnect it from the power source to avoid potential electrical issues.

3. Dry the iPhone: Use a soft, lint-free cloth to gently dab and wipe the exterior of the iPhone to remove any excess water. Avoid rubbing or pressing too hard, as this could push water further into the device.

4. Remove the SIM card: Take out the SIM card, as water can get trapped in the SIM card slot and cause corrosion over time.

5. Allow to fully dry: Place the iPhone in a dry, well-ventilated area and allow it to fully dry out completely before attempting to power it on again. This can take several hours or even days depending on the extent of the water exposure.

6. Avoid charging or using until dry: Do not try to charge or use the iPhone until it is completely dry, as this could lead to short circuits and further damage.

7. Consider professional repair: If the iPhone has been submerged in water for an extended period or shows signs of water damage, it's best to seek professional repair services from Apple or an authorized repair center. Attempting to repair water damage yourself could cause more harm.

The key is to act quickly, disconnect power, dry the device thoroughly, and avoid using it until it is completely dry to minimize the risk of permanent water damage to the iPhone's internal components.
