What should I do if the touch screen of my mobile phone fails?

If you use a vivo phone, you can refer to the following methods to deal with screen insensitivity:

1、? 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 equipment at the ambient temperature of 0℃~35℃.

2. Did you 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. Exit into vivo official website-my-online customer service-slide to the end-online customer service-enter into manual customer service for consultation and understanding.

3, a key to accelerate the deletion of background programs

If there are too many background programs, or there are abnormal programs residing in the background, it may affect the touch screen effect. It is recommended to speed up or clean up the background program with one click and try again.

Note: Please check whether the "one-button screen lock" application is installed. Some third-party "one-button screen lock" software will conflict with the system's own screen lock, 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、? Projection film

If you use non-original film, it may affect the touch screen effect. It is recommended to remove the film or go to the customer service center to re-film it. Address of vivo Customer Service Center: Go to the APP-My-outlet of vivo official website /vivo Mall and select the current city to get the address and contact information of the service center. It is recommended to call in advance before going to avoid empty running, plan your trip reasonably and travel safely.

6, whether into the liquid or fall damage.

If the screen is not sensitive to touch, it is recommended to take the machine to vivo customer service center for testing.

7、? Replace the standard leakage charger or data cable.

If a non-standard charger is used, the touch screen function of the device may be affected when charging. It is recommended to use standard charger and data cable to charge.

8、? Restart equipment

Restart the phone:

1), press and hold the phone power button to pop up the restart option to turn it off;

2) Slide down the top of the mobile phone screen twice to bring up the shortcut bar details page/slide up the bottom of the screen to enter the control center, and click the shutdown/restart switch;

3), forced to restart the phone; (Mobile phone crashes or the card is recommended immediately)

① ① models of funtouch OS 3.2 and subsequent systems: press and hold the power button and the volume down button at the same time 10 second or more;

② Press and hold the top round key 10 second or more to forcibly restart the mobile phone (NEX 3/NEX 3S is applicable);

③ System model before ③Funtouch OS 3.2: Press and hold the power button 12 seconds or more.

9、? Upgrade system version

The new version improves the compatibility and stability, and can upgrade the viewing system.

10. 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 respect: it is generally 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. Please bring the purchase voucher and equipment to the vivo customer service center for testing.

Other scenes are insensitive:

1. Tested the touchable area of the screen by third-party software (such as Ann Bunny and other software), and found that the four corners of the screen could not be touched, questioning the screen quality.

The four corners of the screen belong to the cutting position in the manufacturing process, and this area will not respond to the touch operation, which is not a screen quality problem and will not affect the overall touch performance of the screen. Please feel free to use.

2. In power-saving mode, when operating the card, the dynamic effect of the picture is not smooth:

The device is in energy saving mode (the battery icon in the status bar shows yellow). In order to increase battery life, the screen refresh rate will be switched to 60Hz, and the fluency of some dynamic effects (off/start/exit/slide up) will be reduced. It is recommended to enter Settings-Battery, switch to normal mode (turn off power saving mode) and use View.
