If the phone is flooded, is the message still there after changing the motherboard?

Please don't panic if the mobile phone is flooded. We divide the situation into three types:

One,

Falling into clear water when electrified;

Second,

Falling into non-corrosive liquid during power failure;

Third,

When charged, it falls into unclean water, or whether it is charged or not, it falls into corrosive liquid or viscous liquid or other partially clean liquid.

The first two cases have a great chance of being saved, and there may not be any sequelae. The latter depends on luck. Of course, if you are unlucky, PPC will rot in your pocket.

The biggest problem after PPC enters the water is how to deal with it. First of all, in the case of 1 and 2, never think that the machine is scrapped. Don't think it's flooded, just tear it down. Below I should make some suggestions for various situations:

One,

In the case of electricity falling into clean water, this situation generally does not need to be disassembled.

1, power off as soon as possible.

2、

Dry it hard (depending on the situation, if you pick up the phone immediately after falling into the water, consider not to dry it), but don't slam the machine and try to throw the water off the screen. If water drops remain on the screen, there will be traces after drying.

3、

Put it under a slight heat source such as a desk lamp and spotlight, and let the water disperse slowly. This process takes more than six hours. Don't use strong heat sources such as hair dryers in a hurry.

4. If there is something left on the screen, and it is serious, don't deal with it according to the first and third points, because the electronic circuit treated in this way can work normally, but the screen may be ugly. Can be sent to the nearest maintenance department for treatment or self-disassembly for cleaning.
