Why did vivo mobile phone fail to install Gansu Party Construction app?

If you mean the prompt when installing the software: Not installed or failed to install, please investigate and handle it according to the following methods:

1. Please check whether the storage space of the mobile phone is enough. It is suggested to use I housekeeper to clean up the storage space of mobile phones in time, uninstall uncommon software, and keep the remaining storage space above 20%.

2. This may be caused by inconsistent signatures of software versions. If the old version of the software is installed on the mobile phone, it is recommended to uninstall the old version before installing it.

3. If the installation of the app in the app store fails, the data in the app store may be abnormal. You can press and hold the app store icon -App Info-Store- to clear the data on the desktop.

4. Some software may not be compatible with the Android system of the current mobile phone due to its long development time. It is recommended to download other similar software for use.

5. If the application is installed through other third-party channels (not the application store), the "Install Unknown Application" may not be opened, resulting in the failure of software installation. You can go to Settings-Applications and Permissions-Permission Management-Install Unknown Applications-Find the corresponding software-Allow unknown applications to be installed.

6. If the problem is not solved, it is suggested that the screenshot or screen recording of the problem be sorted out and fed back to the online customer service for help. You can enter vivo official website-My-Online Customer Service, enter labor, and consult online customer service feedback.
