How to provide first aid to a drowned smartphone?

Question

Do it yourself

Guys SOS!!! Dropped xiaomi redmi note 4 in water. Now the display naturally malfunctions (the image flashes). Please give advice on first aid and advise a good service in Moscow. Thanks in advance.

Answer 1

I did this:
1. Disassembled as much as possible.
2. Put everything in rice. It draws out moisture.
3. Waited a day.
The phone worked for a long time after that.

Answer 2

1) immediately remove the battery and do not insert it until the repair is completed
2) if possible, disassemble it
3) dry it with warm air (hair dryer), but not 200+ degrees, so that the plastic does not lead
4) take it to the workshop
I would take it apart completely, dry it so that no water left nowhere and tried to turn it on. Does not plow - change parts. Or a smartphone. New note 4 costs $150

Answer 3

Alternatively, after parsing with alcohol, clean the boards (available)
