Apk file not installing in android says "You may not have proper app for viewing this content" I'm trying to install apk file in Samsung but it says "You may not have proper app for viewing this content". I've checked "allow installation from unknown source" option in security, but no luck. Please help me to sort this out.
Such Issues generally occur when you try to open the file from within an Application (Messenger, Whatsapp etc.) other than File Manager (any such application with similar privileges) or Play Store.

So, please make sure you are accessing it from File Manager.


  If you are not aware of the source of the APK and if it's not from a trusted source please don't install it directly.
