The phone has been flooded;

The phone is used for too long;

Or you can try to remove the protective film to clean the screen. After finding that the phone's touch screen is not working, we can also try to press the lock screen button back and forth a few more times.

Many friends when using mobile phones, suddenly found that the touch screen of the mobile phone failed, I don't know what caused it, and I don't know how to fix it, this article will talk about the reasons and solutions for the failure of the mobile phone touch screen.

Now there are many kinds of mobile phone touch screens, there are single touch, multi-touch, and the screen manufacturers are different, the quality and sensitivity of the screen are also different, and the touch screen is composed of many parts, one of the parts has a problem, it will lead to the failure of the touch screen, and then talk about the solution.

1. Restart your phone.

In the early years, the system of old-fashioned mobile phones was written inside the phone, which is very different from today's smartphones, and one of the biggest differences between old-fashioned mobile phones and smartphones is that smartphones will crash.

If you find that the touch screen of the smartphone is out of order, it is not necessarily that the touch screen is damaged, it may be that the smartphone is dead, press and hold the power off button for 3 5 seconds, the phone will automatically shut down, and the touch screen will automatically recover after powering on.

Second, the dust problem.

Truth be told, this kind of problem is very rare, but it was encountered once. As mentioned above, there are many kinds of touch screens of mobile phones, and the sensitivity is also different, when some dirty things or dust are stuck on the screen of the mobile phone, it will affect the sensitivity of the touch screen of the mobile phone, if the size of the dirty thing is larger, it will form a touch operation on the touch screen, resulting in the failure of the touch screen of the mobile phone.

If the phone screen hasn't been cleaned for a long time, you might as well clean up the dust, and the touch screen may return to normal.

Third, the problem of wiring.

If the mobile phone has been injured before the problem with the touch screen, it is possible that the mobile phone has been injured and the cable of the touch screen is not in good contact. Although the internal parts of the mobile phone are relatively compact, and the internal injuries are not visible on the exterior of the mobile phone, there is still a chance that the wiring will loosen due to falls and vibrations.

If the touch screen of the phone is still not working after trying to restart the phone and clean up the dust of the phone, then you can only find after-sales inspection and let it help repair it.

1. The touch screen is broken (such as greasy or magnetic environment).

2. Motherboard leakage.

3. The battery is aging and damaged.

When using the mobile phone, if the screen is faulty, the user can press and hold the home button under the lock screen, then turn on the voice control function, and then resume the touch selection function. You can wait for a while, and then you will find that the problem with the touch screen has been solved.
