Prompt APK installation failed during connection, connection button cannot appear
There are two reasons for this problem:
- The installation is not open on the phone to install an unknown source.
- Some phones require manual intervention during the installation process. If you do not click install on your phone, you will not be able to complete the installation.
Solution:
- Open the phone to allow the installation of unknown sources.
- Re-plug the phone, look at the installation prompt pop-up on the phone, and manually click the installation according to the prompt.
