If the screen is not sensitive, the following methods can be used for troubleshooting:
1. If the ambient temperature of the equipment used is too low, the touch screen effect may be affected. It is recommended to keep the equipment used at the ambient temperature of 0℃~35℃.
2. 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.
For the method of closing barrier-free service, please click on the webpage link to consult online customer service.
3. 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 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、? 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、? If you use non-original film, it may affect the touch screen effect. It is recommended to remove the film or go to vivo customer service center to re-film it.
6、? 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.
7. If the screen is not sensitive to touch, it is recommended to take the machine to the vivo customer service center for testing and processing.
8、? 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" 12 seconds or more.
For the models launched after September 20 17 and the new mega-silent models (X20 and later models): press and hold the "power button"+"volume down button" 10 second at the same time.
NEX 3/NEX 3S: Press and hold the top round key for more than 10 second.
9、? The new version of the system improves the compatibility and stability, and optimizes the performance. Please go to Settings-System Upgrade (some models are Settings-My Device -iQOOUI Version) to check the system version information. If it is not the latest version, it is recommended to upgrade the experience.
10. If the device is in power-saving mode (the battery icon in the status bar is yellow), in order to increase the 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.
1 1. Check whether the touch screen of a single software or all software is insensitive 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.
Inquire about the address and contact number of vivo customer service center: Go to the service outlet of "vivo official website /vivo Mall" APP-My-or click the webpage link and select the current city to get it.
Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) when you go, and call the service center staff in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
