If your Xiaomi Mi 4 has fallen in water and has been water damaged
Here’s what you should do if your Xiaomi Mi 4 has fallen if water. It’s quite simple to know how to act when you have the elements in mind about this type of problem.
Before you turn back on your device, if it’s still wet, it should be completely dry first. This holds if you want to charge your battery. Any wet component can damage the entire motherboard and may even destroy some or all of the circuit components.
To completely dry your phone, wrap your Xiaomi Mi 4 in a piece of cloth and put it in a rice bag for 4 to 5 hours at least, the rice dust would absorb much of the moisture inside your mobile.
If you are lucky, you will be able to recover your Xiaomi Mi 4. If not, take it to your preferred repairer’s customer service and have it repaired, if still possible.
Let your Xiaomi Mi 4 dry naturally
The problem with water damage is that it can be very difficult, if not impossible, to hunt down and repair exactly what has been affected. If you have exhausted all options, your last chance would be to disassemble the phone and remove the circuit board from your Xiaomi Mi 4. Especially if you think it has been damaged.
This will remove any trace of water and minerals that water may have left behind, even after drying. Let it dry for several hours and reassemble your Xiaomi Mi 4. We highly recommend going through a professional to do all these steps however.

If your Xiaomi Mi 4 has a liquid contact indicator
A liquid contact indicator can be a good way to tell if the inside of your Xiaomi Mi 4 has taken water or not.
A liquid contact indicator (LCI) is a small indicator that changes from white to another color, usually red, after contact with water. These indicators are small stickers that are placed on several points within electronic devices such as laptops, smartphones in general, and could be available on your Xiaomi Mi 4. But please check if this is the case as it can vary from one specific model to another. In the event of a faulty appliance, authorized service personnel may check that the appliance has been in contact with water. After contact with water or other liquids, your Xiaomi Mi 4 may not be covered by the warranty. Liquid contact indicators are also known by other names, such as water-damaged adhesive tapes, a water damage sticker, a water contact indicator tape, a submersion indicator liquid, or whatever.
The main purpose of the liquid contact indicator is to have a connection to the cause of a defect in electronic devices.
The LCI can also be used to avoid liability and guarantee discussions about your Xiaomi Mi 4, if it is triggered. Yet, there may be reasons to sometimes doubt about the reliability of such an indicator:
- A longer but not extreme exposure of a device in a humid environment can trigger a LCI.
- In theory, water can reach the LCI, but the electronics below could not be affected, for example when a small raindrop falls in the connector of the shell of your Xiaomi Mi 4.
- A user should be able to use a device under normal circumstances.
For example, an Xiaomi Mi 4 is normally used while traveling, often outdoors.
It may rain, or start raining outside.
A device must not fail immediately. Again, such circumstances could trigger LCI on your Xiaomi Mi 4.
Thus, a liquid contact indicator could be triggered on Xiaomi Mi 4, without pointing to liquids causing a default.
Liquid contact indicators are good for eliminating the liquid cause of the fault observed on your Xiaomi Mi 4. LCIs can be replaced, they are easily available in electronic stores online.
But on the other hand, the use in warranty claims, makes them prone to potential misuse.
Manufacturers have therefore introduced LCIs that are more difficult to reproduce, even with small holographic details.
In any case, we do not advise you to ever replace an LCI on your Xiaomi Mi 4, if there is such a LCI on your phone.
Liquid contact indicators can be placed in several places in electronic devices.
For example under the keyboard, in the SIM slot or in several places on the motherboard.
Sometimes the liquid contact indicators are placed so that they can be inspected from the outside.
For example, there may be an LCI in the headphone connector, dock connector, and near the SIM card slot.
We let you check if this is the case on your Xiaomi Mi 4. In a Samsung Galaxy Standard smartphone for example, there may be an LCI under the battery cover near the battery contacts.
