Chrome And Browser Installs
After a deliberate download, Android may open Settings with an option such as "Allow from this source" for Chrome, Samsung Internet or another browser. Confirm that the named app is the browser you used. Enable only that source, return to the installer and read the package prompt before continuing.
When installation finishes, return to Settings, search for "Install unknown apps" and disable the permission for that browser. This reduces the chance that a later website can start another package installation from the same source.
