1. Disassemble the entire machine first and be prepared to use the corresponding screwdriver before doing so.
2. When removing the screen, be sure to carefully separate the small chip that connects the screen to the motherboard from the motherboard.
3. Before removing the metal shield insulation layer, tear off the network access card and the card slot sticker under the network access card.
4. The last step is to dry with a hair dryer, but do not blow it towards the screen for a long time. Such a high temperature will damage the screen. Even if the screen has a watermark, you can still use the phone normally. Water in the screen is normal. It will dry in two days and you will see the watermark inside getting smaller and smaller.
5. Blow out the front and back of the motherboard to ensure no moisture remains. Eliminate as much moisture as possiblee of the earpiece and buttons.
6. Finally, place the disassembled cell phone in a dry and noisy place. It is best to leave it for about two days before reassembling it.
