What to do if the touch screen of your mobile phone fails

1. If you are using a vivo mobile phone, you can refer to the method for dealing with an insensitive screen: Confirm the ambient temperature. If the ambient temperature of the mobile phone is too high, Low may affect the touch screen effect. It is recommended to keep the mobile phone in an ambient temperature of 0℃35℃.

2. The method to deal with an insensitive screen is as follows: Confirm the ambient temperature. If the ambient temperature of the device is too low, it may affect the touch screen effect. It is recommended to keep the device at an ambient temperature of 0℃35℃.

3. It is recommended to wipe off the water droplets on the surface of the phone before using it for touch operations. Please confirm whether the charger is Honor's standard charger. When using the touch screen while charging, the power supply voltage may be unstable, which will cause greater interference to the touch screen, thus affecting the touch screen experience.

4. Please press and hold the "power button" for more than 10 seconds and try to force restart the phone. If the problem still cannot be solved, it is recommended that you bring the relevant purchase voucher to the Huawei Customer Service Center for testing. Warm reminder: In the EMUI 10 version, the way to force restart the phone is to hold down the volume down button and the power button at the same time for more than 10 seconds.

The phone screen can light up, but the touch screen cannot be used

Take Huawei P40 and EMUI0 system as an example. The reason why the phone screen stays on but does not turn off: The phone screen has static electricity and needs to be cleaned. , static electricity on the mobile phone screen may also cause the touch screen to malfunction. Gently wipe the entire screen with your hands.

If you are consulting about an Honor mobile phone and your phone has a touch screen failure, you can troubleshoot according to the following methods: To ensure the accuracy of the troubleshooting results, please make sure before troubleshooting: the screen surface is clean and free of oil stains and water Stains, etc., and the presence of liquid on the screen surface may cause the touch screen to jump around and become insensitive.

If you are using a vivo mobile phone, you can refer to the method to deal with an insensitive screen: Confirm the ambient temperature. If the ambient temperature of the mobile phone is too low, it may affect the touch screen effect. It is recommended to keep the mobile phone in an environment of 0℃35℃ temperature.

You can try restarting your phone. If it still doesn’t work, it is recommended that you try the following methods: ① Pull down the status bar on your phone and click One-click Acceleration (One-click Cleanup) or enter the program management on the desktop to close the background Programs and clear cache files to increase available memory and avoid phone crashes due to insufficient memory.

If the internal screen of the phone can be displayed but the touch screen cannot be used, it is possible that our touch screen has been damaged, or the cable connecting the touch screen to the motherboard is loose. This requires disassembly. Judgmental.

What types of mobile phone touch screens are divided into

1. There are currently two types of mobile phone touch screens: Resistive screen: The sensitivity is average and requires a little force to be recognized when clicking. Mobile phones with this kind of screen usually have a touch pen with a pen point correction function. Non-intelligent machines, domestic no-name machines, and some Symbian machines also use it.

2. Mobile phone touch screens are divided into two types: resistive screens and capacitive screens. Most of the currently popular touch screens are lens screens, which are flat resistive and mirror capacitive screens. Most of Nokia's are resistive screens and capacitive screens. The representative is iPhone.

3. It is divided into resistive screen and capacitive screen. Resistive screen is the best; resistive screen: used by relatively early touch screen machines.

4. Mobile phone screens are classified according to screen material, including LCD and OLED; according to screen display technology, there are ASV, CBD, NOVA, RetinaDisplay, etc.; according to operation mode, there are touch screen and non-touch screen. Category; divided by form, there are notch screen, water drop screen, pearl screen, hole-punch screen, full screen, etc.

5. Types of touch screens: According to different sensing methods, touch screens can be roughly divided into four categories: resistive, capacitive, infrared, and ultrasonic. Among them, resistive and capacitive technologies currently have the most promising market prospects, and it may be difficult for other technologies to catch up in the short term.

6. Touch screens can be distinguished from technical principles and can be divided into five basic categories: vector pressure sensing technology touch screen, resistive technology touch screen, capacitive technology touch screen, infrared technology touch screen, and surface acoustic wave technology touch screen. Among them, the vector pressure sensing technology touch screen has withdrawn from the stage of history.
