Why is the mobile phone screen not rotten and the touch screen often out of control?

Poor touch may be due to poor removal of the touch screen hardware or external factors that cause the touch screen to not be able to use normally, for example, the touch screen may jump when charging, and the poor quality of the screen film may cause the touch screen to be out of control.

Touch screen: touch screen, also known as "touch screen", "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts, when it touches the graphic buttons on the screen, the haptic feedback system on the screen can drive various connection devices according to the pre-programmed program, which can be used to replace the mechanical button panel, and create vivid audio and video effects through the liquid crystal display screen. As the latest computer input device, touch screen is currently the simplest, most convenient and natural way of human-computer interaction.

It gives a new look to the multi-first, and is a very attractive new multi-interactive device.

Nowadays, the touch screen of mobile phones is mostly capacitive screen.

Capacitive screen: Capacitive touch screen technology works using the human body's current induction. The capacitive touch screen is a four-layer composite glass screen, the inner surface and the interlayer of the glass screen are each coated with a layer of ITO, the outermost layer is a thin layer of silicone glass protective layer, the laminated ITO coating is used as the working surface, four electrodes are drawn out at the four corners, and the inner layer ITO is the shielding layer to ensure a good working environment.

When the finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance, which is a direct conductor for high-frequency currents, so the finger draws a small current from the contact point. This current flows out of the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance of the finger to the four corners, and the controller derives the position of the touch point by accurately calculating the proportion of these four currents.

Since it's either hardware or software, restore the appearance settings or go to a repair shop and ask him to calibrate the screen for you.

If you are using a Huawei phone and your phone has a touch screen failure issue, you can troubleshoot it by following the steps below:

1.If the ambient temperature of your phone is too low, the touch screen may malfunction, which is affected by the physical characteristics of the screen device itself, and it is recommended that you try to keep your phone at an ambient temperature of 0 -35.

2.If the problem persists, we recommend that you bring your phone to a Huawei Customer Service Center with your proof of purchase.

If you haven't backed up your data before, you're at risk of data loss when you detect it.

The problem of touching the mobile phone is the problem of damaged touch screen or wiring, it is not excluded that the problem of the motherboard circuit and chip, the screen is not damaged, it does not mean that the screen is not broken, this needs to be detected to know that it is the first problem.

You start by finding the settings menu. Find the corresponding function options in the settings.

It is recommended to go to the after-sales service for repair.

Go to the place where the phone is repaired and ask, this question is a bit professional.

The phone screen is not broken, and the full-screen touch fails.

Dear, I'm glad to answer for you: the phone screen is not broken, the full-screen touch is out of orderA: Dear, The reason why the phone screen is not broken but doesn't slide is usually the following:

1. The mobile phone is used for too long, the background running system and the mobile phone are more garbage, the whole system responds seriously and slowly, and the system response is not timely in the case of screen operation, resulting in jamming failure. 2. There are a small amount of water stains or impurities on the mobile phone screen or mobile phone, which affects the screen recognition process and causes the screen to fail and do not move. 3. After the mobile phone was accidentally dropped to the ground and collided with an external force, the touch screen or internal display cable of the mobile phone was disconnected (poor contact), resulting in the screen being unable to touch and failing.

Extended information: Precautions for mobile phone screen maintenance: 1. Afraid of "high" temperature:

The "high" temperature here is not to bake with fire, but to reach a temperature of about 40 degrees, which may cause the capacitive screen to drift, and if it is at this temperature for a long time, the capacitive screen will be braided, do not sunbathe, and do not use it for a long time in the hot sun. 2. Extreme fear of static electricity: it is easy to break through the capacitive screen.

Although the layer of glass on the surface of the capacitive screen mobile phone has undergone a certain antistatic treatment, it does not mean that it can withstand the static electricity of the human body, and many people like to paste an inferior screen sticker on the surface of the mobile phone that is easy to produce static electricity. 3. Fear of conductive media such as oil stains and sweat: covering the screen will form a conductive layer, which will cause the screen to drift, wash it by hand, dry it and use it again.

4. Fear of unstable voltage: Generally, when the finger touches the capacitive screen, it will "suck" a little current, and then the screen will evenly transmit power from the four corners to the position where the thumb is located, and use this to do positioning, so the capacitive screen will "drift" or even fail when the transmission voltage is unstable In addition, if the power is less than 20%, it is best to charge it immediately. 5. Fear of magnetic fields:

Especially the electromagnetic field, the small magnet on the capacitive screen for a while, the capacitive screen will temporarily fail (may also cause permanent damage) Don't get close to the speaker or magnetic screwdrivers and other items, don't put the handy phone on the speaker when you get home. Thank you for your patience. The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best!

Peace and joy!

First, the mobile phone is used for too long, the background running system and the mobile phone garbage are more, the whole system response is seriously slow, and the system response is not timely in the case of screen operation, resulting in Caton failure, you can clean up the mobile phone garbage to see if it can solve the problem.

Second, there is a small amount of water stains or impurities on the mobile phone screen or rubber mobile phone, if the screen is slowly ringing to the screen recognition, resulting in the screen failure point does not move, you can wipe the screen with a delicate rag.

Third, system problems, restart the phone, long press the power button, and select Restart.

Fourth, after the mobile phone is accidentally dropped and collided by external forces, the touch screen of the mobile phone or the display line of the inner mold part is in poor contact, resulting in the screen cannot be touched and malfunctioning, and it is necessary to go to a professional mobile phone after-sales maintenance station for testing.

This is your mobile phone screen is broken, go to the after-sales service to take a look, no, you can only change the screen.

The touch is out of order, go to the phone store and have a look.
