What is the reason for the failure of mobile phone touch screen?

If you are consulting HONOR, your mobile phone has a touch screen failure. You can check according to the following methods:

1. In order to ensure the accuracy of the survey results, please ensure that:

1, the screen surface is clean, and there is no oil stain or water stain. The appearance of liquid on the screen surface may cause the touch screen to jump and be insensitive.

2. Do not operate in soft places such as quilts and sofas. The touch screen will be subjected to uneven pressure and is not sensitive to probability.

3. There are no high-intensity magnetic fields such as microwave ovens and induction cookers nearby, which will interfere with electronic components and cause the touch screen to jump abnormally.

4. The outdoor temperature is low and the indoor temperature is high in winter. After entering the room from the outside, the indoor water vapor will liquefy when it is cold, and there will be a layer of water droplets on the screen of the mobile phone. It will cause insensitive touch and slow response. It is recommended to clean up the water droplets on the surface of the mobile phone before using the touch operation.

5. Please confirm whether the charger is a glory standard charger. If you use the touch screen while charging, the power supply voltage may be unstable, causing great interference to the touch screen, thus affecting the touch screen experience. I suggest you try not to use your mobile phone when charging. If it is necessary to use the mobile phone while charging, please use the original charger and remove the protective case to enhance the touch experience. (When the hand directly touches the mobile phone, it can ensure the conduction between the human body and the mobile phone and reduce the interference. )

6. The film should not be too thick, otherwise it will affect the sensitivity of the touch screen. It is recommended to replace the film with a thickness not exceeding 0.2 mm or replace the official protective film.

7. Please drop down the status bar to view in the shortcut settings menu or search in the settings, and enter "NFC" to see if the NFC function is turned on. NFC will automatically open the specified application after scanning a specific scene.

8. Confirm whether the system response is abnormal because your mobile phone has not been cleaned for a long time. Please confirm whether it can be solved by restarting the phone.

Note: The method of forcibly restarting the mobile phone is to hold down the volume down key and the power on key 10 seconds or more.

2. If there is no problem after investigation, please check whether the touch function of the device is normal according to the following methods:

1. Please open the "My Glory" APP on your mobile phone, find the device detection/intelligent detection, and click to enter (see My Glory APP, Device Detection for details).

The operating interface of different versions of the APP may be slightly different, please refer to the actual interface.

After the interface is opened, the tests will be carried out in sequence, and the steps that do not need to be tested can be skipped by clicking.

2. After detecting the touch screen, click Start Detection on the interface, and start to draw full-screen squares with your fingers according to the interface prompts, and the screen detection is completed.

3. If the detection screen is abnormal, it is recommended that you back up important data in advance and back up third-party applications such as QQ and WeChat separately. Take the purchase voucher to the glory authorized service center for professional testing. Open Glory official website, click Service Support, and find a service shop to inquire about the nearby Glory Authorized Service Center. It is recommended to call the service center in advance to confirm the business hours before going to the service center, so as to facilitate your travel ~
