What should I do if I am prompted with "App not installed" when installing the latest PandaVPN for Android?
1. In the security settings of the phone, not enabling the tab "Unknown Sources" to allow the installation of applications from unknown sources will cause this problem, please follow the steps below: Settings => Security => Allow the installation of applications from unknown sources.
2. Insufficient device memory may also cause this problem, please ensure that the device has enough space to install PandaVPN.
3. PandaVPN downloaded from a different source may also cause this problem, please uninstall the old one and install the new version again.
