Why mobile phone screens tend to fail in winter

Why is the touch screen sometimes not very sensitive after winter?

This problem is also quite common in daily life. Many factors can cause the touch screen of a mobile phone to malfunction. The reason why the capacitive screen malfunctions is that the surface is partially charged, which is commonly known as static electricity, making it impossible to determine whether there is a finger or other conductor (such as a capacitive pen) pressing on it. The screen may be partially charged due to friction in the pocket, frequent strong pressing, dust on the screen, excessive sweat on the hands, or static electricity on the human body due to dryness in winter. In addition to the static electricity on the human body caused by dryness in winter, temperature is also an important factor. Capacitive screens have relatively strict use conditions, such as temperature and humidity. In theory, the ambient temperature of the capacitive screen is required to be between 0 and 35 degrees Celsius. In winter, the temperature in the north is generally below 0 degrees Celsius, so the screen may naturally malfunction.

After simply answering the question, let's continue reading. Today, the editor will introduce to you how to repair screen failure and how to maintain the capacitive screen of your mobile phone.

How to fix a screen failure

No matter what the reason is for the screen failure, don't subjectively conclude that there is a problem with the phone. You can try the following methods:

1. Turn off your phone, let it sit for a few minutes, then turn it on and try again. If the battery of a phone can be removed, it is best to remove the battery as well.

2. Find a USB data cable, then connect your phone to your computer and try the effect again.

3. Wash your hands or wet them before operating the screen.

4. With wet hands, touch the metal part of the USB port on the phone with one finger, then press the other finger on the ground for about two seconds and try again.

5. If the screen drifts, if conditions permit, you can consider using a hot hair dryer to blow the screen, set it to medium settings, and turn the phone off. When the screen feels hot, restart it.

6. Use transparent tape to repeatedly stick and tear off the malfunctioning area until the screen resumes touch function.

7. If the above methods are ineffective, you can try a more radical electric shock method. The method is very simple. First, cover the faulty part of the screen with a paper towel moistened with water, and then use the electrostatic device in a lighter to shock the screen to change the electric field. Note that this method is the last resort. Try not to try it unless it is absolutely necessary.

If all methods have been exhausted and still don't work, then you can consider sending it to a repair station for inspection. However, normally speaking, if it is not a problem with the phone itself, one of the above methods can always repair screen failure problems caused by the environment in daily life.

The weak points of mobile phone screens and daily maintenance methods

Mobile phone screens are not that delicate. In fact, we can prevent screen failure through detailed maintenance. Here we will take stock of some weaknesses of mobile phone capacitive screens, and summarize the methods of daily maintenance of mobile phone screens.

1. Capacitive screens are extremely sensitive to static electricity: it is easy to break through the capacitive screen. Although the glass on the surface of capacitive screen phones has been treated with anti-static treatment, it does not mean that it can withstand the static electricity of the human body in winter. In addition, many people like to stick a low-quality screen sticker on it that is prone to static electricity. Therefore, friends who like to put their phones in their trouser pockets and run naked should pay attention. If it is not troublesome, you can consider buying a cloth bag for your phone.

2. Afraid of conductive media such as oil and sweat: covering the screen will form a conductive layer, which will cause the screen to drift. So before using the phone, try to wash your hands and dry them before using. Also pay attention to cleaning the screen regularly to keep the screen dry. In addition, when taking a shower in winter, try not to bring your phone into the shower room, regardless of whether your phone is waterproof or not.

3. Afraid of "high" temperature: "High" temperature here does not mean baking with fire, but a temperature of about 40 degrees may cause the capacitive screen to drift. If it is kept at this temperature for a long time, the capacitive screen will easily be game over. This is why it is not recommended to use mobile phones to run large games for a long time. At the same time, try not to sunbathe with your mobile phone, and do not use it for a long time under the hot sun.

4. Afraid of magnetic fields: especially electromagnetic fields. If a small magnet is placed on the capacitive screen for a while, the capacitive screen will temporarily fail, and it may also cause permanent damage. Don't get close to speakers or magnetic screwdrivers and other items. When you get home, don't put your phone on the speaker.

5. Afraid of unstable voltage: Generally, when a finger touches the capacitive screen, it will "suck" away a little current, and then the screen will evenly send electricity from the four corners to the position of the thumb, and use this for positioning. Therefore, the capacitive screen will "drift" or even fail when the transmission voltage is unstable. It is best to charge it immediately when the power is less than 20%.
