No warranty for water ingress How does Apple officially know that mobile phones have water ingress| Love to play computer games

Cherish your mobile phone and stay away from the toilet. The toilet has become the largest killer of mobile phones. Since most of the current mobile phones are not waterproof, they will be completely destroyed once they fall into the water, and this belongs to man-made damage, which is not officially guaranteed, as is the case in Apple's warranty regulations. But maybe some people will want to dry their mobile phones and who will know that my mobile phone has fallen into the water. But how could Apple be so easily fooled? Just shine a flashlight and you can immediately know whether the phone has ever been flooded.

How did they know that the mobile phone had entered the water? Apple staff will shine a flashlight on the headphone socket and the data cable interface. There is a water ingress test paper at the headphone socket and the data cable interface, which can be used to detect whether the phone is water ingress. It is difficult to find these test papers because they are stuck in some inconspicuous positions.

How to judge whether there is water ingress through these test papers? In fact, it is very simple. These test papers were originally white, but they will turn red when they are exposed to water. So Apple staff can only use a flashlight to see what color the test paper is. Of course, we can also use this method to check whether the purchased second-hand iPhone has received water.

In addition to the outside of the fuselage, there are also these test papers inside the fuselage. The red circle in the following figure is the water inlet test paper inside the fuselage. The test paper was originally all white. Now we see that the right side of the test paper turns red because we used water drops to test before, and the part of the test paper stained with water will turn red immediately.

However, it is often said that my mobile phone has not fallen into the water, but why the water test paper turns red. In fact, these water ingress test papers not only turn red when they touch water, but also turn red when they are exposed to extreme humidity, such as when you take your iPhone into the bathroom.

Can we buy back new water ingress test paper so that we can paste them back on the iPhone and cheat Apple staff later? We can really buy these on the omnipotent Taobao. It's not easy to paste them back, because the test paper is placed in some narrow parts. However, if Apple's staff is not discerning enough and RP is good, we will still have some special solutions, such as applying correction fluid or white paint for painting on the water inlet test paper. Red will turn white immediately, and we will not be afraid to touch water in the future!!
