What should I do if the touch screen is not sensitive when charging my phone?

The voltage is unstable, it is not the original charging head, it is recommended to change one.

The touch screen is not working, so it is a problem with the screen, you can go to the repair shop to check it. Now the lifespan of the mobile phone is only three years, so you can get a new mobile phone when you arrive.

The temperature of the capacitive screen, when the temperature of the mobile phone is higher than 45, the capacitive screen will fail for a short time, so when the mobile phone is charging, especially the mobile phone with a protective case, the temperature will easily rise, resulting in the screen failure.

Generally speaking, mobile phone charging has nothing to do with the touch screen, if you feel that the touch screen is not sensitive, it is recommended that you go to the mobile phone store to consult.

If you are using a Huawei phone and the touch screen is not sensitive when the phone is charging, you can do it by the following methods:

1.It is recommended that you try not to use your phone while charging.

2.If you must use your phone while charging, it is recommended that you use the original charger and remove the case before using it.

3.If you have used tempered film, it is recommended to remove it, or use Huawei original protective film.

Although playing with mobile phones while charging is not advocated at all, there will inevitably be an accident. If you are chatting with the goddess and suddenly your mobile phone battery is in an emergency, is it very sad? At this time, after connecting to the power supply, something more sad happened, the screen drifted, the words were inaccurate, and finally it simply failed.

In fact, it is not uncommon for the screen to fail while charging. For most people, screen failure is also a very annoying thing. So, what is the cause of screen failure?

We don't need to delve into the knowledge of electricity that is too difficult, so the author will briefly explain the reasons.

In fact, all this is mainly due to the capacitive screen of the mobile phone. We know that the capacitive 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 (conductive glass), the outermost layer is a thin layer of silica glass protective layer, the interlayer 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 a finger touches a metal layer, a coupling capacitance is formed between the user and the touchscreen surface due to the conductor nature of the human body.

The capacitance is a direct conductor, the user's finger can suck a small current from the contact point, and then this current flows out of the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners, and the controller obtains the position of the touch point by accurately calculating the proportion of these four currents.

You must know that the vast majority of mobile phone screens today are capacitive screens. Since the capacitive screen is controlled by capacitive induction, it shows that the capacitive screen has high requirements for the stability of the power supply. The AC waveform is sinusoidal, while the battery power supply is DC, which has high stability.

When charging directly, using a general inferior charger will make the screen not work properly, that is because the stability of the inferior charger is extremely poor, the capacitance used is too inferior or there are no inductive components, and there are very serious ripples when detected with an oscilloscope. However, some chargers cannot remove the pulse waveform of the pulse transformer due to the aging of the capacitor for a long time, resulting in residual waveforms. Working under this kind of ripple, it will dry up the screen, and even cover the surface of the screen with static electricity, so that the screen can not correctly identify the accurate position of the human body** contact, so that it cannot work normally.

That's why the screen is out of order.

Then, after finding the cause, there will naturally be a solution. First of all, use the original charger and data cable of the brand as much as possible. Compared to non-original chargers, original** can provide more stable current.

If you don't have an original charger on hand, it is recommended that you choose to charge your computer.

If you are using an OPPO mobile phone, use a non-original charger and data cable when charging, or charge under an interfering circuit, which may interfere with the touch screen and cause no function, please replace the original charger and data cable of the mobile phone and try charging in other places.

Most of today's mobile phones are touchscreen phones.

How to deal with the insensitive screen of vivo mobile phone:

1. 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 at 0 35 ambient temperature.

2. Mistakenly turn on the talkback mode in barrier-free.

If you enable the talkback mode, the touch mode will change, and a green frame will be displayed on the screen when touched. You can press and hold the volume up button + down button for 3 seconds at the same time to exit the talkback mode, or double click Settings - double click More Settings - Swipe to Accessibility with two fingers - Double click Accessibility - Double click to close Talkback.

3. One-click acceleration to clear background programs.

If there are too many background programs, or there are abnormal programs in the background that may affect the touch screen effect, it is recommended that you speed up or clean up background programs with one click before trying again.

Note: Please check if it is installed"One-click lock screen"class applications, some third-party"One-click lock screen"The software will conflict with the lock screen that comes with the system, resulting in random jumps, such as jumping to the lock screen, etc., it is recommended to uninstall the third party"One-click lock screen"and other types of software.

4. Whether there is liquid or stain on the finger or screen.

Liquid or stains on your fingers or screen will affect the sensitivity of the touchscreen, so it is recommended to clean it with a clean, dry cloth before trying again.

5. Check the film.

If you use a non-original film, it may affect the touch screen effect, so we recommend that you remove the film or go to the customer service center to reapply the film.

6. Replace the standard charger or data cable.

If you use a non-standard charger, it may affect the phone's touch screen function when charging, so it is recommended to use the standard charger and data cable for charging.

7. Restart your phone.

Please restart your phone or force restart your phone to see if it returns to normal.

Force Restart Method:

Models released before September 2017 (models before x20): Press and hold"Power button"More than 12 seconds.

Models released after September 2017 and new models released later (x20 and later): Press and hold at the same time"Power button"+"Volume down key"More than 10 seconds.

NEX 3 NEX 3S: Press and hold the top round button for more than 10 seconds.

8. Upgrade the system version.

The new version improves compatibility and stability, and can be viewed by upgrading the system.

9. Check whether it is a single software or all software in a fixed area The touch screen is not sensitive.

A single software is not sensitive to touch in this area: it is generally a reason for software incompatibility, it is recommended to go to the app store to upgrade the software, and at the same time feedback to the software customer service.

All software is not sensitive to touch in the same position: it may be that the screen is faulty, please bring the purchase voucher and mobile phone to the vivo customer service center for detection.

This is because the model of your charger is not paired, I don't comment on other mobile phones, just use oppo, its mobile phone, I myself have personal experience, no matter when the original is charged? Your play is not affected, but, as long as it is newly matched, reassembled, he is always a little insensitive, so this has something to do with your use method, maybe you go to the place where you sell the mobile phone, that is, where you buy the mobile phone, ask him to help you with an original charger, this problem will be solved, I hope my experience can help you.

Can you get your phone repaired?
