What should you do first if your mobile device suffers from liquid damage?

In the event of liquid damage to a mobile device, the first course of action should be to power off the device. This step is critical because keeping the device on can lead to short circuits, which can cause further damage to the internal components. When liquid enters the device, it can create electrical paths that shouldn't normally exist, leading to malfunctions that can permanently damage the circuitry.

Turning off the device prevents additional electrical activity from occurring, potentially saving important components from being compromised. After powering off, further actions such as disassembly, cleaning the circuit boards, or replacing the battery can be considered, but those should only be done after ensuring that the device is completely off.

This approach emphasizes the importance of promptly addressing the immediate risk to the device's integrity before undertaking other repair or salvage efforts.
