    I created an application and sent the .apk file to my client. When he tries to open it he get "Can't open file".

    He's device : Vodafone Smart X9, model VFD 820, running Android 8.1.0

    I told him to enable "Unknown Sources" in Security Settings.

    Can someone please give me advice on how he can open the .apk I sent?

    On my Samsung J7 Pro, I just enable "Unknown Sources" then I can install the apk.
