How to deal with water stains on the screen of iPhone 4 after water enters it

What should I do if my iPhone 4 gets wet and there are traces of water stains on the screen?

1. Do not turn on the phone and shake it

After the iPhone is soaked in water, it should be shut down immediately. If left on, eddy currents will be generated, causing a short circuit and burning the motherboard. Therefore, it must not be turned on. In addition, do not shake the fuselage randomly to drain water after water has entered. This will move the water around, causing more parts of the phone to be affected by the water. So, keep your phone stationary and take it to a professional repair shop for repair as soon as possible.

2. The first thing to do after shutting down

After shutting down, use a towel to gently wipe the water on the phone case to ensure the surface is dry. Then quickly remove the SIM card and place it in a dry place. Next, use paper towels to drain the water from the earphones, DOCK interface and SIM card slot.

3. Wipe hard-to-remove stains with a damp towel

There are many situations of flooding and water intrusion, including fresh water, muddy water, sea water, juice, etc. To prevent fresh water from entering the phone, you can first turn off the phone and then use a towel to gently wipe the moisture on the surface of the phone. If water gets into the phone interface, you can use a paper towel or cotton swab to remove the water. However, for water containing impurities such as muddy water, sea water, and juice, it is recommended to send it to the Apple store for repair. Impurities in muddy water and seawater will remain inside the mobile phone and become the main cause of mobile phone failure. Beverages such as juice and coffee contain sugar or salt, which can also corrode your phone. After confirming that the phone is shut down, use a wrung-out towel to carefully wipe away the impurities inside the phone. If there are foreign objects attached to the earphones and DOCK interface, it will also cause corrosion and malfunction of the mobile phone, so they must be removed carefully.

After removing stains, be sure to use a dry towel to absorb the moisture in your phone. Also, avoid using water to remove stubborn stains to prevent additional moisture from seeping into the damp interior of your phone.

After the iPhone is submerged in impurity-rich muddy water or seawater, it is common for the iPhone to be unable to handle it. This must be sent to the nearest Apple store for repair.

4. Do not turn on the machine immediately after the outside is dry

Do not turn on the iPhone even if the body and interface are wiped dry. Because it still takes time to dry out the water that has invaded the inside of the phone. Natural drying is the best way to restore your phone. Never use a hair dryer to quickly dry out the moisture in your phone. The iPhone's battery is built-in, and the heat from a hair dryer may age the battery and cause the phone to malfunction. After drying the water, place the phone in a box with photo desiccant and let it dry for 4 to 5 days. If there is no special desiccant, you can also use the food desiccant included in the food packaging. Although the effect is not as good as the former, the corresponding effect can be achieved by using more points. In addition, if there is no desiccant, you can also use a dehumidifier for closets such as rice or binchotan. Drying time varies depending on the degree of flooding and seasonal changes, and generally takes 2 to 5 days.
