Understanding Phone Screen Flicker and Blackouts: A Comprehensive Guide

Have you ever experienced the frustration of turning on your smartphone and witnessing its screen flicker briefly before going black just seconds later? This phenomenon, often observed after exposing your phone to water, can be concerning. In this comprehensive guide, we will delve into the reasons behind this behavior and provide actionable solutions.

What Does It Mean When a Phone Screen Flickers Then Goes Black?

When a phone screen flickers and goes black a few seconds later, particularly after exposing it to water, it generally indicates that the device is still dealing with internal moisture. This moisture can be a result of vapor that has not yet fully evaporated or has been trapped within the phone's internal components.

It's important to note that allowing a device to continue functioning while dealing with moisture can lead to serious internal damages such as short circuits or other fatal problems. Therefore, it is recommended to leave the phone off and ensure that it is completely dry before attempting to use it again.

Why It Happens After Water Exposure

If your phone was exposed to water, it's entirely possible that the water has permeated into critical circuits, potentially causing them to short circuit. This is a common occurrence, and although the water may evaporate over time, it's relatively rare for the phone to return to normal without some issues.

However, the more likely outcome is that the phone has undergone a process known as 'toasting,' in which the water has damaged the motherboard and the display panel. This damage can be permanent, especially if the phone was not shut off immediately after exposure to water and the battery was not removed.

Steps to Take After Water Exposure

1. Shut Off the Phone: The first step is to immediately turn off the phone. If possible, remove the battery as well to prevent any further electrical damage.

2. Allow It to Dry: Place the phone under an LED light, which provides some heat to aid in the evaporation process without causing too much damage. Allow the phone to air out for 3-4 days to ensure that all moisture is evaporated.

3. Use Rice for Absorption: Another effective method is to place the phone in a sealed plastic bag filled with uncooked rice. Rice is known for its ability to absorb moisture, which can help dry out the phone.

4. Pray and Incense: For those with a spiritual inclination, placing the phone near an incense stick or under an LED light for a few days can be a symbolic way to ensure the device is prepared to be turned on.

5. Professional Repair: If the phone shows signs of significant damage, such as a flickering screen followed by a blackout, it's best to seek professional repair services. A certified technician can assess the extent of the damage and provide a solution if it's repairable.

Preventing Future Water Damage

To avoid similar issues in the future, consider investing in a water-resistant case and protections. Keep your phone dry and avoid exposing it to water or moisture whenever possible.

Understanding and managing water exposure can save your phone from further damage. Remember, allowing the phone to dry properly and addressing any issues promptly is key to maintaining the health of your device.
