Android is an open source eco-system which allows the installation of all kinds of Applications without any prior scrutiny. Android scans each APK file during installation and notifies if something is not correct with the App. The error message which is generally seen is “This APK File Might Contain Unsafe Content”, Make Sure You Trust the Sender before you Open and Install it”.
The Error generally comes when you try to install the App from 3rd party Application from where the file is shared. The Android OS which generally scans the App during installation may skip the scan due to Apps small size or Apps nature. This makes it difficult for the Google Protect to detect the App Code and its content. This results in the App being recognized as unsafe and asks the user to trust the App from the source through which he received it.
And many times when you try to install this unsafe file you see the error.
What to Do if the App says APK is not Safe?
Generally, the App is Safe to install and the warning message is due to the inability of the 3rd party app to verify the content of the App. If you believe the App is from the safe source and has normal content then you can proceed forward without any worries. Make sure you enable unknown sources before going for installation;
Settings ⇒ Security ⇒ Unkown Sources (Turn it On)
