Now, there is no need to panic if your mobile phone gets dropped in water or you get stuck up in a bad rain and your clothes as well as your mobile phone gets wet. All you need to do is follow the following three tips that will fix your phone with water damage:-
(A) Act Quickly : straight away get into action and remove every cover and detachable part you possibly can like memory card, the SIM card, battery and back cover, etc. Now use a toilet paper or a thin cloth to blot away any excess water you can see inside of the phone and be sure to get as much as you can. Otherwise, all this water will start evaporating and collecting in hard to reach various places in your phone.
Your phone may work now if it was only submerged for a short period of time.
(B) Quick Drying : Grab a hairdryer and start drying your phone paying extra attention to the battery housing as this normally has small holes which allow air (and ironically enough water) into the phone.
A warning: Don’t hold the hair dryer too close to the phone. Keep it at a distance whereby if you put your hand in front of the hair dryer it would not burn you. Bringing it closer could damage your phone’s electrical components. If i am sounding serious, try putting a hair dryer up against a sheet of paper for a few seconds. It turns it brown would you want that happening to the inside of your phone?
If 20-30 minutes of this doesn’t work than go to plan C.
(C) Long Term Drying : By putting it in a warm dry place you allow the water to slowly evaporate and escape through the holes in the phone (remove the covers and battery when doing this).
