Mobile phone screens sometimes fail or get out of control. Any good ideas?

Please refer to the processing method 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℃.

2. Turn on the barrier-free intercom mode by mistake.

If the intercom mode is turned on, the touch screen mode will change, and the screen will display a green box when touching the screen. You can press and hold the volume up key+down key for 3 seconds at the same time to exit intercom mode, or double-click Settings-Double-click More Settings-Slide two fingers to accessibility-Double-click Accessibility-Double-click to turn off intercom.

3, a key to accelerate the deletion of background programs

If there are too many background programs, or there are abnormal programs in the background, it may affect the touch screen effect. It is recommended that you try again after one-click acceleration or cleaning up the background program.

* Note: Please check whether the "one-button screen lock" application is installed. Some third-party "one-button screen lock" software will conflict with the screen lock that comes with the system, leading to jumping around, such as jumping to the screen lock interface. It is recommended to uninstall the third-party "one-button screen lock" software.

4. Are there any liquids or stains on your fingers or screen?

Liquid or stains on the finger or screen will affect the sensitivity of the touch screen. It is recommended to clean with a clean dry cloth and try again.

5, check the film:

If you use non-original film, it may affect the touch screen effect. I suggest you try to remove the film or go to the customer service center to re-film it.

6. Replace the standard charger or data cable.

If a non-standard charger is used, the touch screen function of the mobile phone may be affected when charging. It is recommended that you use a standard charger and data cable for charging.

7. Restart the phone:

Please restart the phone or force it to try to see if it is back to normal.

Forced restart method:

20/kloc-models launched before September, 2007 (models before X20): press and hold the "power button" for more than 12 seconds.

Models released after September 20 17 and new models (X20 and higher): press and hold the "power button"+"volume down button" for more than 10 second at the same time.

NEX 3/NEX 3 seconds: Press and hold the top round key for more than 10 seconds.

8. Upgrade the system version:

The new version improves compatibility and stability, and can be upgraded to view the system.

9. Check whether a single software or all software is insensitive to the touch screen in a fixed area:

Single software is insensitive to touch in this area: this is usually due to software incompatibility. It is recommended to go to the app store to upgrade the software and give feedback to the software customer service.

All software is insensitive to touch in the same location: the screen may be faulty.
