Even if a wet phone seems dead, there’s a good chance it can be resuscitated as long as you act fast. This is a ASAP moment: Your phone’s warranty probably doesn’t cover water damage. Although, your phone may behave fine at first but soon it will start to react. Here are a few steps that will help you dry out your wet phone.
Step 1. Without wasting time, turn off your phone. Do this within seconds of the accident — even before you dry it off with your t-shirt. The goal is to cut the power before any water has a chance to hit the circuitry and short circuit it.
Step 2. Dry the outside of the phone with a lint-free towel, paying close attention to any ports, speakers, and microphones. Disassemble any parts — like the SIM card and battery — and dry them, too.
Step 3. Place the device and parts in a zip-top storage bag (or a bag of rice as many would suggest), to be very efficient at absorbing moisture.
Step 4. Wait 72 hours. This is probably the hardest part, but rest assured that you’ll be OK, even if you haven’t checked Instagram or snapchat in three days.
Step 5. Power your phone on. Three days have passed, giving the phone ample time to relieve itself of the moisture. If you did everything right, your phone should be back in business.
A few important notes
Here’s the deal: Much of this method relies on chance and a little luck. The most important part is that you rescued your phone quickly, and that it was powered off before any liquid hit the circuit boards.
Know that even if you were able to revive your phone, there’s a chance that any water contact (or worse, chemical- or salt-laden water contact) will corrode the parts over time. So if a year later, your phone begins to die a slow and painful death, you’ll know why.
The goodnews is that you can upgrade to the Samsung s7 or Samsung s7 edge which is fully resistant to dust particles and water resistant up to 3m.
