However, if you continue to power on and use it after water intrusion, malfunctions and black screens will appear again after a few weeks. The cement mixed with water and dust will corrode circuits, components, and chips to a certain extent, causing short circuits, disconnections, etc. again. Chip burnout, etc., and often it is not the damage of one or two components, but many components, circuits, chips burnt out at the same time, etc. At this time, it is very difficult to repair, and many hidden faults may be left.
