Liquid ingression, commonly known as water damage, is generally a sour point when you are told that your phone or other electronic device has been diagnosed with this problem.
If your mobile phone has been diagnosed as having liquid ingression it means that your phone has signs of water damage inside the phone. It does not necessarily mean that the phone has been dropped into a bucket of water, which is a common misconception.
All electronic devices contain small sensitive electronic parts and a small amount of water can cause that part to corrode over time. Another common misconception is that if someone tells us that our phone has water damage we only recall the recent events and not the phone call we took whilst walking in the rain three months ago. Some of the most common ways that a mobile phone can become water damaged is by using it in the rain and by using it whist sweating. Facial sweat can leak down and creep inside a mobile phone without a person even knowing.
Mobile phones come with a special litmus paper that is stuck to the phone at various places. These litmus papers can often be found under the battery as well as inside the phone on the printed circuit board that the user cannot see. These litmus papers are often white, or are white with a red line. If the phone has been submerged in water the litmus paper will turn red.
It is recommended that you do not keep your mobile phone in your shirt top pocket if around water as it can easily fall out into a bucket of water, toilet, swimming pool or kava! Avoid using the phone when walking outside in the rain and keep the phone away from moisture and car aircon vents.
