The mobile phone was flooded and used for more than a month. I can't open the wireless network now, and so is the data flow of the mobile phone.

1. No matter what kind of water the phone falls into, you should take out the battery of the phone directly at the first time (instead of pressing the power off button).

2. Use napkins or cotton balls, cotton swabs, etc. to absorb all the water that can be dried outside.

3. If you fall into clean water, you can clean your mobile phone with anhydrous alcohol, because alcohol evaporates quickly, and the water on the circuit board can also evaporate together (provided you have anhydrous alcohol). If it falls into sewage, it should be cleaned immediately. Clean up the visible dirt first, and brush off the impurities attached to the component pins with a brush.

4. Swing the hair dryer from a distance with a hair dryer. Be careful not to blow too close or blow in one place for a long time.

5. Keep the mobile phone in a cool and dry place for 24 hours. If there is no hair dryer to dry the water, it is best to leave it for 48 hours.

6. Install a fully charged battery for trial operation. If it can't be turned on, it will be repaired.
