Free CompTIA A+ 220-1101 Practice Question
A customer has brought in a mobile device that has been accidentally submerged in water. The device powers on, but the touchscreen is unresponsive. After confirming that no other physical damage is visible and checking that the device is out of warranty, what is the BEST next step to take in resolving this issue?
Perform a factory reset to eliminate any system errors causing the touchscreen to be unresponsive.
Replace the touchscreen immediately as it's the most likely component to fail due to liquid exposure.
Disassemble the device to inspect for corrosion and residual moisture, then clean and dry the interior components.
Update the device's software to the latest version to ensure that the unresponsiveness isn't due to software issues.
