If you are using an OPPO mobile phone (ColorOS system), it is recommended to follow the following methods to avoid further damage after the OPPO mobile phone tablet is flooded with water or liquid

1. Please do not turn on or charge after water ingress, at this time, powering may cause short circuit damage to the components of the mobile phone and tablet.

2. Please do not try to shake off the water by throwing the mobile phone and tablet, this operation may cause the liquid to seep into other components.

3. Please do not use a hair dryer or oven to bake the mobile phone and tablet, so as to avoid the internal flow of liquid and damage the components, as high temperature and high heat may cause permanent damage to the components of the mobile phone and tablet.

4. Take out the SIM card and memory card of the mobile phone in time, if the mobile phone is a removable battery, please remove the battery.

5. Use paper towels and cotton swabs to dry water stains on the surface of the mobile phone and tablet.

When exercising, avoid putting your mobile phone in your pocket to prevent sweat from entering your mobile phone, and you can wear a mobile phone armbag.

It is recommended not to play with the mobile phone and tablet when showering, and if you really need it, you can put the mobile phone and tablet in a sealed plastic bag or waterproof bag to prevent the mobile phone and tablet from getting wet.

The phone is flooded, don't turn it on immediately to check it, at this time, the water enters the inside of the fuselage, and the motherboard may be burned out when the boot is started, so it is recommended not to do any operation, use a dry towel to absorb the water, and then send it to the local OPPO customer service center in time for testing and processing. You can go to the service of the OPPO official website - service outlets to inquire, choose the OPPO customer service center closer to you to test, the staff will help you, you can also enter the OPPO WeChat***-click [Service Station] - select [Appointment Service], or enter the official website, select the appointment network - select the appointment date and time - fill in personal information, which can save queuing time.

What should I do if my phone can't be turned on when water gets in.

If the OPPO mobile phone is not disassembled in time after the water is entered, there may be a variety of mobile phone failures in the future, such as the black screen of the mobile phone, the mobile phone can not be turned on, the mobile phone does not charge and a series of failures, today we just received an OPPO mobile phone, the customer described that the mobile phone can not be turned on after the water is in, and the mobile phone charging does not have any response, today we Kunming Jiuyi mobile phone repair will come together to see how to repair and solve the OPPO mobile phone that entered the water.

According to the customer's description, since the mobile phone is a water inlet machine, we first disassemble the phone and remove all the accessories of the mobile phone for a comprehensive cleaning, after removing the motherboard, we found that the water ingress of the mobile phone is not very serious, after cleaning up the residual moisture, use the DC power meter to power on and turn on, and find that the mobile phone can be turned on. It's also normal to test other features, it's just that nothing happens when the phone is charged.

According to the master's previous experience in repairing the water inlet machine, the mobile phone does not charge after the water ingress, generally there is a problem with the chip or the path is corroded, just disassembled and found that the motherboard corrosion is not serious, the use of a multimeter to measure the positive pole of the battery is only 1V, and the normal charging should have a voltage of 5V, directly replace the charging IC.

After replacing the charging IC, re-measure the positive voltage of the battery, and find that the voltage of 5V is normal, plug in the charger for charging test, and find that it can be charged, but the charging prompt is abnormal charging, as shown in the figure below

This situation is mostly caused by the open circuit of the battery positive detection path, open the mobile phone repair principle drawing, and find that this detection path is directly connected to the power supply IC, and there is also a protective inductance on the line to the power supply IC.

At first, I suspected that the protective inductor might be damaged, resulting in the disconnection of this path and not charging, but the actual microscope observation of the motherboard found that the protective inductor of this line has been officially waterproofed, and there is obvious sealing treatment around the inductor, as shown in the figure below

Eliminate the inability to charge caused by inductor damage, then only the corrosion under the power IC causes the phone not to charge, directly remove the power IC 380°, replace a new power IC, test and charge again after replacement, troubleshooting.

All functions are normal in the boot test, and the maintenance is over.

For the OPPO mobile phone with water ingress, if you find that the mobile phone has been flooded, the correct thing to do is to turn it off immediately, and then find a repair shop as soon as possible to disassemble the mobile phone for processing, do not try to turn on or charge, once the mobile phone is turned on or charged, it is likely to cause the motherboard to burn out or seriously corrode, which will lead to more serious failures.

Water ingress of the mobile phone After liquid ingression, in order to avoid further damage, it is recommended to dispose of it according to the following methods:

1. Judge the power on and off status of the mobile phone, if the mobile phone is turned on, please turn it off immediately, if the mobile phone has been turned off, please do not try to turn it on;

2. Take out the SIM card and memory card of the mobile phone in time, if the mobile phone is a removable battery, please remove the battery;

3. Use paper towels and cotton swabs to dry water stains on the surface of the mobile phone;

4. If you do not clean up after liquid ingress, it will accelerate the oxidation and damage of the internal components of the mobile phone, so it is recommended to send it to the customer service center for testing and maintenance as soon as possible.

Precautions: 1. Please do not turn on or charge after water ingress, at this time, powering may cause short circuit damage to mobile phone components;

2. Please do not try to shake off the water by throwing the mobile phone, this operation may cause the liquid to seep into other components;

3. Please do not use a hair dryer or oven to bake the mobile phone, as high temperature and high heat may cause permanent damage to the components of the mobile phone.

This is available for all OPPO models.
