How to fix your cell phone in less than 3 minutes after you have dropped it in water.
Here are the instructions:
Try this from wikiHow:
Remove your phone from the water immediately. The longer your phone stays submerged, the more chance it has of shorting out. Quick reflexes can mean the difference between a working phone and a dead one.
Power down the phone. To do so, press and hold the Power button, then slide the button at the top of the screen right when prompted. The sooner you can turn off your iPhone, the higher its chances of recovery will be.
- If the screen is off but you’re not sure if the phone is on, quickly press the Power button to see if the screen turns on. If it does, proceed to power the phone off. If it doesn’t, leave it off.
Remove any case that is on the iPhone. If your iPhone has a case, it may be holding in moisture; removing the case will allow the phone to breathe.
Remove your iPhone’s SIM card and tray. To do so, insert a SIM removal tool or an unbent paperclip into the SIM tray’s hole to pop the SIM tray out. Completely remove the tray so that water can escape.
Use a dry, absorbent cloth to wipe down the phone. Get all of the excess moisture off with an absorbent cloth. Make sure to get the moisture out of the charging port, the volume keys, the headphone jack and any other crevices.
Swab out ports with a toothpick and piece of cloth. Get a thin piece of cotton, like an old shirt, and wrap a single layer around the end of a toothpick. Use this to absorb any excess water from the charging port and headphone jack.
Place the iPhone in a warm, dry location. The best way to get rid of the water inside of your iPhone is to simply let it air dry in a warm place for as long as possible.
- Many guides will report that placing your iPhone in a bag of rice will help draw the water out. This has been proven false–simply letting your iPhone air dry is the most effective way to fix it.
- Air drying will be more effective if you are able to remove the battery from the iPhone.
Wait at least 48 hours. The longer you can wait, the more successful your drying process will be. If you can wait longer than 48 hours, 72 hours may be even more effective.
Check for the water damage indicator. Each iPhone has a small indicator that tells repair technicians that the phone has received water damage. The indicator is a piece of plastic that turns red when it comes in contact with too much water. You can check this indicator yourself to see if your phone may be damaged. Use a flashlight to help you see inside the port. This indicator usually means that you likely won’t qualify for free repair, in which case you may want to consider fixing the phone yourself.
- iPhone 5 and up – Look for a red indicator in the SIM tray port on the screen side of the phone.
- iPhone 4S – Look for a red indicator in the charging port or in the headphone jack.
