How to fix “App not installed” Error – Android

While installing some apps you might get the below error:


App not installed error android

This happens for 2 reasons:

1. If an older version of the app is already installed.

2. If Google Play Security Scan is enabled and it doesn’t find the app safe enough to be installed.

Google Play Security Scan normally doesn’t allow apps downloaded outside of Google Play to be installed and throw the above error “App not installed.” while trying to install it.
