Jin Li's mobile phone button is broken. The manufacturer insisted that there was water. What should I do?

1. First disassemble the whole machine and prepare to use the corresponding screwdriver before.

2. When disassembling the screen, pay attention to gently separate the small chip connected to the motherboard from the motherboard.

3. Before removing the metal shielding isolation layer, tear off the network access card and the card slot sticker under the network access card.

4. finally, blow dry with a hair dryer, but don't blow on the screen for a long time. Such a high temperature will damage the screen. Even if the screen has a watermark, you can use the phone normally. The water in the screen usually dries up in two days, and you will see that the watermark inside is getting smaller and smaller.

5. Blow the front and back of the motherboard to ensure that there is no water residue. Try to blow out the moisture on the receiver and button.

6. Finally, put the removed mobile phone in a dry and noisy place, preferably for about two days, and then install it.
