My phone fell in water
My phone fell in water, it's not switching on properly. Only lights then logo comes on and it is swolen
An Android smartphone produced by Huawei, released in April 2015.
As you know water and electronics and electricity are not a good mix.
The minerals in the water cause corrosion and the water also provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion process starts immediately and will not stop until it has been thoroughly cleaned away.
First do not turn on your phone and then you need to with the phone turned off, remove the battery as soon as possible from the phone to minimize further damage.''
Then you need to completely dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% or less and is not as effective. If you do check the label to verify the amount
Here is a link that in general describes the process.
As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.
You may also have to replace the battery as sometimes it is hard to recover a battery from water damage.
Here is a link to a video which shows how to disassemble the phone. Although it is in Russian (I think) hopefully it may still be of some help.
If this process seems too daunting, take your phone to a reputable, professional mobile phone repair service experienced in water damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
