Hi there, so my phone fell in a shallow toilet and the water got into it through the charger , headset, and speaker ports. the screen is actually still working however there are two water spots at the from close to the charger ports, (I have an A21S) please can you all provide me with some advice
Hi, The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone’s operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away First do not try to charge or to turn on your phone and then remove the battery as soon as possible from the phone to minimize any further damage. Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use “rubbing alcohol” as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better Here is a link the that describes the process. Electronics Water Damage As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well Hopefully after you have done all this the phone might possibly work correctly again. Here is a link to a teardown video for your phone, that may help. If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
